Previous Action: None DEPARTMENT: COMMUNITY DEVELOPMENT SUBJECT: Approval of the recommendation of the Sign Board of Appeals for a variance to allow a 6' tall by 11' wide by 22" deep sign at the entrance of Good Shepherd Catholic Community on Tinker Road and allow the existing signs to remain, Case G-03-007 - by Consent Reading and Public Hearing Good Shepherd Catholic Community is currently constructing a new 36,000 square foot facility on its 16 acre campus at 1000 Tinker Road. In conjunction with the new building construction, Good Shepherd Catholic Community is requesting a variance from the sign regulations to construct a 66 square foot institutional monument sign and to allow the existing 32 square foot monument sign to remain. On November 12, 2002, the plant manager for Good Shepherd Catholic Community contacted the Colleyville code enforcement officer and was advised that an institutional sign was limited to 90 square feet. The plant manager was also informed by the planning and zoning assistant on the same day that two monument signs were permitted on the property so long as there was a minimum of 60 feet of separation. The plant manager subsequently placed an order for a block of limestone for the sign's construction under the assumption that the 66 square feet was well under the maximum size limit. No permit had been applied for at the time this information was obtained from City staff. However, on April 15, 2003, a sign permit application was submitted and denied due to the sign exceeding the size limit and the existence of a monument sign on the Tinker Road street frontage. The applicant was advised to request a variance from the sign regulations. Current Requlations The maximum size institutional monument sign allowed by the current sign regulations is 32 square feet. The applicant is requesting approval to construct a 66 square foot monument sign. The maximum height of a monument sign under the current regulations is 10 feet. The proposed monument sign is only 6 feet in height. The current regulations only allow one institutional monument sign per street frontage. The proposed monument sign, if approved, would be a second monument sign along the Tinker Road frontage. Agenda Briefing Resolution R-03-2142 Page 2 of 6 Proposed Requlations Over the past year, the City Council has been reviewing a proposal to revise the Colleyville sign regulations. Included in the proposal is a revision to the size regulations for institutional monument signs. The following is an excerpt from the proposed revision to the sign regulations. B. Institutional Siqns - These regulations provide for on-premises and off-premises Institutional Signs to assist the public with the location of these types of uses. 1. On-Premises Institutional Sign: The purpose of an On-Premises Institutional Sign is to identify schools, churches, hospitals or similar public or quasi-public institutions. One On-Premises Institutional Sign per street frontage shall be allowed on the premises where the institution is located and in accordance with Table 7-1. All On-Premises Institutional Signs shall be constructed as a monument sign as defined in this Land Development Code. The maximum area, height, spacing, and setbacks of an On-Premises Institutional Sign shall be in compliance with the specifications contained in Table 7-2, provided that an On-Premises Institutional Sign located within a commercial zoning district may comply with the requirements of a General Business Sign. Max. Area 45 s. f. T Lo Institutional Sign (On-premises) a. Minimum Setback: Eight feet (8') from an abutting street right-of-way and thirty feet (30') from any side or rear property line adjacent to another property. b. Minimum Thickness: No On-Premises Institutional Sign shall be less than four and one-half inches (4- Y;,") between vertical face planes. c. Changeable Reader Board: An On-premises Institutional Sign may include a changeable reader board area, provided the combined gross surface area does not exceed the maximum sign area and provided that no more than fifty (50) percent of the maximum allowable sign area may be used as a changeable reader board area. A permit is not required to change the message on a changeable reader board. For purpose of this regulation, a changeable reader board may include an electronic message area. Analysis The Good Shepherd Catholic Community campus has approximately 410 feet of frontage and three driveways on Tinker Road. There is one driveway on Pleasant Run Road. There is an existing monument sign adjacent to the Pleasant Run Road driveway. There is also an existing monument sign located adjacent to the western most driveway on Tinker Road and situated approximately 60 feet from the southwest corner of the property. The proposed new monument sign will be located approximately 210 feet east from the existing monument sign on Tinker Road and will be generally centered on the new church building. As a part of the process for preparing the proposed revisions to the sign regulations, staff conducted a survey of existing institutional monument signs and compiled a table showing the sizes, heights and other characteristics of these signs. The information obtained from the field survey is shown in the table below, which has been arranged in order of descending size. The largest institutional monument sign in the table contains 98 square feet. It is not clear when Agenda Briefing Resolution R-03-2142 Page 3 of 6 this sign was constructed. Many cities have sign regulations that contain a formula to allow larger signs in proportion to the lot size or the amount of lot frontage. Colleyville's regulation for institutional signs does not contain this type of provision. City of Colleyville -- Institutional Monument Signs Address Business Name 2600 Hall-Johnson Rd.

Staff review of a permit application would have discovered the oversized sign being proposed and that there was an existing sign along that street frontage. However, even had the applicant applied for a sign permit and the permit denied, the applicant could still have applied for a sign variance. Staff notified all the adjacent properties regarding this sign variance. No written comments have been received regarding this variance request. According to Section F (5) of the Sign Code, the recommendation of the Sign Board of Appeals regarding all sign variances is forwarded to the City Council for consideration. At the April 21, 2003 meeting, the Sign Board of Appeals recommended approval of the sign variance request with the following requirements: The lights on the sign will be turned off at 10:00 p.m., and that other, existing signs would not have to be moved.

CGS Signs is requesting a variance from Chapter 7 - Sign Regulations, of the Colleyville Land Development Code to construct a 50 square foot wall mounted "Reader Board" sign (see Attachment 2) with changeable letters to be used by the owner to announce events at their facility. Currently there are no provisions in the sign regulations to incorporate a changeable "reader-board" in to an attached wall sign. The current regulations allow changeable message boards as a portion of a freestanding Multi- Purpose Monument sign. Current Requlations Wall mounted signs are permitted for General Business purposes limited in size to "two times the length of a building fa9ade. This building is 197 feet in width, therefore single or multiple signs as large as 394 square feet are permitted on this wall. The existing "Sunbelt Gymnastics Academy" sign is only 90 square feet and the proposed "reader board" sign is 50 square feet. The combined area of 140 square feet is well within the 394 s.f. allowed by the current regulations. The proposed sign regulations currently being considered by the City Council limits changeable reader boards to fifty percent of the area of a monument sign. There is no provision proposed for changeable reader boards attached to the side of a building. Analvsis The applicant initially requested approval to place the changeable message board toward the northern end of the building (see Attachment 3). However, at the Sign Board of Appeals meeting on April 29, 2003, the initial location of the sign was denied. The Sign Board of Appeals has recommended approval of the sign variance request, provided the sign be situated under the existing wall sign on the east side of the building as shown on Attachment 3. Agenda Briefing Resolution R-03-2142 Page 2 of 2 According to Section F (5) of the Sign Code, the recommendation of the Sign Board of Appeals will be forwarded to the City Council for their consideration. Staff notified all the adjacent properties regarding this sign variance. No comments have been received regarding this variance request.

Jan Levy r;I- Planning ;~Oning Assistant CITY COUNCIL cae<ll AGENDA BRIEFING 'ex",$ MEETING DATE: ITEM # : ORDINANCE # : 05/06/03 8 0-03-1403 CITY MANAGER ! DEPARTMENT HEAD ! FINANCE REVIEW I Previous Action: 04/15/03 DEPARTMENT: COMMUNITY DEVELOPMENT SUBJECT : Approval of Amendments to Chapter 14 of the Land Development Code regarding drainage, fire lane, construction plans and other engineering requirements, Case G-03-006 Second Reading and Public Hearing Standards for concrete streets have been modified from 3,000 p.s.i. specifications to 3,500 p.s.i. concrete in the attached proposed amendments to Chapter 14 of the Land Development Code. First Reading and Public Hearing Chapter 14 of the Land Development Code contains engineering design standards for public improvements, such as water and sewer lines, street projects and drainage facilities. Over the past several months, Community Development and Engineering Department staff has reviewed the regulations in this chapter in response to repeated questions from developers and their engineers for clarification and/or interpretation. Additionally, state and federal requirements that have recently been imposed on municipalities need to be incorporated into the applicable sections within these regulations. Staff solicited and received comments and suggestions from area engineers and developers who responded to our mail-out on December 13, 2002 advising them of the proposed revisions and requesting their input. Many of the comments and suggestions they offered have been incorporated into the proposed text changes. At the March 4, 2003 Pre-Council meeting, the discussion regarding the sewer service line repair policy resulted in a directive to staff to include the appropriate regulations in the Land Development Code to clarify the inspection procedures associated with new sewer line installations. Language has been added in Section 14-165.G to require a video inspection upon sewer tap installation. Also, at the March 4, 2003 Pre-Council meeting, staff was requested to compare the cost and technical differences between concrete with a 3,000 p.s.i. strength and that with a 3,500 p.s.i. strength. Staff contacted a local concrete supplier who indicated that the cost difference amounted to about $1.50 per cubic yard more to go from the 3,000 p.s.i. to 3,500 p.s.i. concrete. This represents a cost differential of approximately 3% more to increase the concrete strength specifications for a typical subdivision street. There is no additional labor or Agenda Briefing Ordinance 0-03-1403 Page 2 of 4 material costs. Charles Jackson of CMJ Engineering recommends our going to 3,500 p.s.i. concrete for roadway construction projects due to the extended life expectancy of an average street. According to the information obtained by the Colleyville Engineering staff, there would be no issue with brittleness of the concrete due to the increased concrete strength. Staff also contacted our neighboring communities to determine their concrete specifications and these are shown in the following table. The specifications contained in the attached draft version of Chapter 14 have not been changed, pending direction from the City Council.

One of the most visible changes being proposed is the manner in which the chapter is organized and presented in order to make it is easier to find certain topics through better paragraph notation and re-numbering of the various sections. The original system generated numerous complaints regarding the difficulty in navigating through this chapter. Attachment 2 is a copy of Chapter 14-Engineering Design Standards of the Colleyville Land Development Code that has been marked to reflect the proposed changes. Text indicated as "strikethrough" is proposed for deletion and text shown as "bold/italics/underlined" is proposed to reflect new regulation. Recommendation Approval Attachments: .

Section 14-170 Drainage and Storm Sewer Improvements 11.11.1. CEI"JER\h A. General - This section pertains to general design requirements for drainage and storm sewer construction in the City of Colleyville. All drainage facilities shall be sized and designed in accordance with the City of Colleyville Drainage Master Plan or as determined by the Director of Public Works SePlliees. 11.11.B R19nQFf C!.hB19h!. TIml~ 4.!1..Runoff Calculations - The selection of which method to use for calculating runoff depends upon the size of the contributing drainage area at the most downstream point of the project. The "Rational Method" is acceptable for designing projects in which the drainage area is less than one-hundred (100) acres. A unit hydrograph method is required for projects with larger drainage areas. 1. No matter which method is used to calculate runoff, a developer or builder of residential property greater than one (1) acre in size, or any property that was platted as a part of an overall tract which was greater than one (1) acre in size (including churches and schools), shall develop the property so that the rate of runoff created by the development as it leaves the property does not exceed the rate of runoff that is currently occurring in the existing conditions. A developer or builder of commercial property greater than one-half (1/2) acre must follow the above guidelines. ~.2. Runoff computations shall be based upon fully developed watershed conditions in accordance with the land use projections in the latest comprehensive land use plan for the City of Colleyville. The design engineer shall size drainage facilities by disregarding the detention effects of upstream property and calculating the runoff as if the off-site property was developed without any detention. If an approved regional detention/retention facility is in operation, the design engineer may size downstream drainage facilities based on consideration of the detention effects of the regional facility. 4.C.Pn~eea~re fer araiRa~e Drainaqe areas less than one-hundred (100) acres Chapter 14 - Engineering Design Standards Page 14 - 29 Colleyville, Texas, Land Development Code aL Computation of Storm water Runoff for drainage areas less than one-hundred (100) acres shall be by the "Rational Method," which is based on the principle that the maximum rate of runoff from a given drainage area for an assumed rainfall intensity occurs when all parts of the area are contributing to the flow at the point of discharge.

Time of concentration is the longest time, without interruption of flow by detention devices that a drop of water takes to flow from the farthest point of the drainage area to the point of concentration (i.e. the point of design). The time of concentration is composed of the inlet time and the flow time in a conduit or channel to the point of design. The inlet time shall be 10 minutes for property zoned multiple family, churches, schools, local business, central business, commercial, or industrial. An inlet time of 15 minutes shall be used for property zoned for parks, cemeteries, agricultural, and single family residential. When designing inlets and laterals, the time of concentration is equal to the inlet time. The design engineer will compare the above specified inlet times to the actual calculated inlet time by computing Chapter 14 - Engineering Design Standards Page 14 - 30 ColleyvilIe, TexJs, Land Development Code the flow time overland and along the gutter to the first inlet. Manning's Equation shall be used to determine flow time to the inlet. The design engineer may use the actual calculated or specified inlet time. In no case shall a longer inlet time be used than 10 minutes for multiple family, commercial, churches, schools, industrial and business areas and 15 minutes for parks, cemeteries, agricultural, and single-family areas. @.D.PFe@e€hm~s Wf; Drainaqe Areas €lrsGlter tFlGlf! of one-hundred (100) acres or more ae.1.For drainage areas if! en(@e~~ of one-hundred (100) acres or more where the use of the "Rational Method" does not provide reliable results, the use of a unit hydrograph method shall be made. The use of a unit hydrograph calculation will be based upon standard and accepted engineering principles subject to the approval of the Director of Public Works SSPli@Qs. Acceptable methods include the Soil Conservation Service (SCS) Technical Release Number 55 or the Corps of Engineers HEC-1 models for drainage areas one-hundred (100) acres or more. &.2. The unit hydrograph method shall be based upon fully developed watershed conditions assuming no effects from the small on-site detention facilities for maintaining the rate of runoff as if the property was undeveloped. The detention effects of large regional detention facilities can be taken into account in unit hydrograph methods. 9.3. Circumstances that may require the use of a unit hydrograph method include sizing open channels, reclaiming floodplains, creating lakes, or building other types of drainage-related facilities on major drainage courses. Design engineers of these types of facilities should be aware that the requirement of designing for fully developed watershed conditions will mean that they will have to calculate these fully developed flows instead of using the flows calculated in the Federal Emergency Management Agency's (FEMA) flood insurance studies for Colleyville or Tarrant County or from studies performed for or approved by the City of Colleyville.

The design of all drainage channels and swales shall assure adequate capacity and minimum maintenance to overcome the result of erosion, silting, sloughing of bends or similar occurrences. fF.4. When performing hydraulic analyses for channel or drainageway design, the one-hundred year (100) Chapter 14 - Engineering Design Standards Page 14 - 35 Colleyville, Texas, Land Development Code year starting water surface shall be based on the following: a. Known water surface elevations should be used where possible. Known elevations are available for some creeks and channels from previous studies approved by the City. b. When known water surface elevations are not available the slope-area method or a rating curve may be used. (1) A rating curve approximates the starting water surface elevation for a given flow by using the relationship between known flows and water surface elevations for the creek. This is an excellent method for determining starting conditions if good data is available to develop the rating curve. (2) The slope-area method approximates the starting water surface elevation by calculating the normal depth for the channel. To calculate normal depth the slope of energy gradient for the channel is required. The energy slope can be approximated using the average slope of the channel or the average slope of the water surface. 9.5. The design of the channel lining shall take into account the super-elevation of the water surface around curves and other changes in direction. In general a radius that is three (3) times the top width of the water surface during the design storm event is recommended for channel bends. +'6. A chain link fence six (6') feet in height, or other improvements as approved on a case by case basis by the Director of Public Works SerVi€BS, shall be constructed on each side of the lined channel. 3.7. Gabion or other forms of channel lining a~El ~ref9rrBel may be used in lieu of reinforced concrete lining with the approval of the Director of Public ~er.ti€ie& Works. 11.11.J DEl'EI'ITI€1rl :DE~mr>1 L. Detention DesiQn - Runoff rates for all land uses shall be limited to the rates that would be produced from single family residential areas. This requirement also applies to the development of sites as churches, schools, and other institutional uses. Detention/retention facilities shall be designed for the fully developed one-hundred (100) year design flood according to the following criteria: 1. The minimum amount of storage volume of the detention basin shall be that volume required to reduce runoff rate durinQ the 100 year event to the undeveloped rate. The outflow structure shall be sized to reduce the 2. 5. 10. 25. 50. and 100 year discharQes to the undeveloped rate. Dedicated detention/retention basins shall also include an additional one foot of freeboard and two feet of sediment storage. The volume of runoff storage for drainage areas greater than one-hundred (100) acres shall be computed using unit hydrograph procedures. Acceptable unit hydrograph procedures are provided in Section 14-170.D.114.S.~.5 of this document. For drainage areas less than one-hundred (100) acres, the above methods are recommended; however, an approximate routing method based on the modified rational method fGrmlolla is allowable. 2. All detention facilities designed shall consider the timing of the flood peak in the main channel into which the detention facility drains. Delaying the peak from a site in lower portions of a watershed may result in a higher peak on the main channel. The Director of Public Works may reauire that upstream and downstream ponds be included in the detention desiQn model. 3. A detention facility shall have enough gradient to ensure positive drainage to the outlet structures so as to avoid nuisance conditions such as standing water, odors, insects, and weeds. A minimum slope of 0.50% towards the outlet structure is required for all grass lined detention facilities. 4. Detention areas in parking lots shall not be: a. In required parking spaces. b. Behind speed bumps unless the speed bumps are made with reinforced concrete. Chapter 14 - Engineering Design Standards Page 14 - 36 Colleyville, Texas, Land Development Code c.

Drainage easements shall be provided for all regional detention/retention facilities and for other detention/retention facilities where two or more owners are involved. 6. Individual Qgetention facilities shall be designed to empty in less than three (3) tv/aRty fe~r ~24) hours, unless it is also serving as an erosion control facility. 7. Detention facilities used as a sediment control facility ~ shall meet the following requirements; a. The sediment control facility shall be designed with minimal velocities such that sediment is dropped and not picked up by flows at any time during the storm event. b. The basin shall be designed with i3€le~~G1te two (2) feet of sediment storage area so that sediment removal is not required more than twice a year. Expected removal periods greater than twice a year must be specified in the maintenance plan and approved by the Director of Public Works S8r;\'ise~. c. Sediment control facilities cannot be used to meet detention requirements unless the volume of sediment is included in the calculations for the detention basin design. 8. The owner shall maintain detention/retention facilities unless the facilities are dedicated to the City of Colleyville. Detention facilities must be properly maintained if they are to function as intended over a long period of time. The following measures are required to ensure the facility functions properly. a. Facilities should be mowed at least twice a year to control weeds and discourage woody growth. b. Debris, litter and accumulated sediment should be removed from detention facilities at least twice a year. Particular attention should be given to removal of debris, litter and sediment around outlet structures. The Director of Public Works may reauire that the property owner remove said debris when in the Director's determination that property damage or a flood hazard may exist. c. Detention basins designed for sediment removal shall be maintained as specified in the maintenance plan and approved by the City with construction plan submittal. 1 ~.1 i.K Fh\:Jl'\fES 4.. M. Flumes - The use of flumes is not recommended for widespread use.

Pressure Grout Mix - Grout shall be comprised of one (1) cubic foot of cement and three and a half (3.5) cubic feet of clean fine sand with sufficient water added to provide a free flowing thick slurry. If desired to maintain solids in the mixture in suspension, one (1) cubic foot of commercial grade bentonite may be added to each twelve (12) to fifteen (15) cubic feet of the slurry. d. Casing Insulators (Spacers) - Use casing insulators for any type of carrier pipe. Insulators shall be high density polyethylene. Insulators shall fit snug over the carrier pipe and position the carrier pipe approximately in the center of the casing pipe to provide adequate clearance between Chapter 14 - Engineering Design Standards Page 14 - 26 Colleyville, Texas, Land Development Code the carrier pipe bell and the casing pipe. Insulators shall be manufactured by "Recon" and be Racci Type or approved equal. 3. Installation a. Tolerances (1) All bores shall be installed at a grade no less that the minimum indicated by TAC, Chapter 317 for the desired pipe size. (2) All bores shall maintain grade enough to ensure desired clearance distances between existing utilities and bore. b. Excavation and Backfill of Access Pits (1) Bore pits must be a minimum of four (4') feet from the back of curb when located for boring under roadways. (2) Do not allow excavation over the limits of the bore or tunnel as specified. Trench walls of access pits adjacent to the bore or tunnel face shall be truly vertical. Shore the trench walls as necessary to protect workmen, the public, structures, roadways, and other improvements. (3) Excavations within the right-of-way and not under surfacing shall be backfilled and consolidated by mechanical methods as specified in these standards for compaction of trenches under roadways. Surplus material shall be removed from the right-of-way and the excavation finished to original grades. Backfill pits immediately after the installation of the carrier pipe is completed. If carrier pipe is not installed immediately after casing pipe installation, the right-of-way Owner may require the access pits be temporarily backfilled until installation of carrier pipe. Plug ends of sleeves to prevent soil migration. (4) Where seeding or sodding is disturbed by excavation or backfilling operations, such areas shall be replaced to meet existing or better conditions. Section 14-170 Drainage and Storm Sewer Improvements A. General - This section pertains to general design requirements for drainage and storm sewer construction in the City of Colleyville. All drainage facilities shall be sized and designed in accordance with the City of Colleyville Drainage Master Plan or as determined by the Director of Public Works. B. Runoff Calculations - The selection of which method to use for calculating runoff depends upon the size of the contributing drainage area at the most downstream point of the project. The "Rational Method" is acceptable for designing projects in which the drainage area is less than one-hundred (100) acres. A unit hydrograph method is required for projects with larger drainage areas. 1. No matter which method is used to calculate runoff, a developer or builder of residential property greater than one (1) acre in size, or any property that was platted as a part of an overall tract which was greater than one (1) acre in size (including churches and schools), shall develop the property so that the rate of runoff created by the development as it leaves the property does not exceed the rate of runoff that is currently occurring in the existing conditions. A developer or builder of commercial property greater than one-half (1/2) acre must follow the above guidelines. 2. Runoff computations shall be based upon fully developed watershed conditions in accordance with the land use projections in the latest comprehensive land use plan for the City of Colleyville. The design engineer shall size drainage facilities by disregarding the detention effects of upstream property and calculating the runoff as if the off-site property was developed without any detention. If an approved regional detention/retention facility is in operation, the design engineer may size downstream drainage facilities based on consideration of the detention effects of the regional facility. C. Drainaoe Areas Less Than one-hundred acres 1. Computation of Storm water Runoff for drainage areas less than one-hundred (100) acres shall be by the "Rational Method," which is based on the principle that the maximum rate of runoff from a given Chapter 14 - Engineering Design Standards Page 14 - 27 Colleyville, Texas, Land Development Code drainage area for an assumed rainfall intensity occurs when all parts of the area are contributing to the flow at the point of discharge. ...... ...P~.~.~...~.~~~.!:l...~....1'l9...~.~\I.~I()p~~...I~.~.~......

Commercial ................................................. . Industrial 0.60 0.70 0.70 0.70 0.70 0.70 0.85 2. Time of concentration is the longest time, without interruption of flow by detention devices that a drop of water takes to flow from the farthest point of the drainage area to the point of concentration (i.e. the point of design). The time of concentration is composed of the inlet time and the flow time in a conduit or channel to the point of design. The inlet time shall be 10 minutes for property zoned multiple family, churches, schools, local business, central business, commercial, or industrial. An inlet time of 15 minutes shall be used for property zoned for parks, cemeteries, agricultural, and single family residential. When designing inlets and laterals, the time of concentration is equal to the inlet time. The design engineer will compare the above specified inlet times to the actual calculated inlet time by computing the flow time overland and along the gutter to the first inlet. Manning's Equation shall be used to determine flow time to the inlet. The design engineer may use the actual calculated or specified inlet time. In no case shall a longer inlet time be used than 10 minutes for multiple family, commercial, churches, schools, industrial and business areas and 15 minutes for parks, cemeteries, agricultural, and single-family areas. D. Drainaqe Areas of one-hundred (100) acres or More 1. For drainage areas of one-hundred (100) acres or more where the use of the "Rational Method" does not provide reliable results, the use of a unit hydrograph method shall be made. The use of a unit hydrograph calculation will be based upon standard and accepted engineering principles subject to the approval of the Director of Public Works. Acceptable methods include the Soil Conservation Service (SCS) Technical Release Number 55 or the Corps of Engineers HEC-1 models for drainage areas one-hundred (100) acres or more. 2. The unit hydrograph method shall be based upon fully developed watershed conditions assuming no effects from the small on-site detention facilities for maintaining the rate of runoff as if the property was undeveloped. The detention effects of large regional detention facilities can be taken into account in unit hydrograph methods. 3. Circumstances that may require the use of a unit hydrograph method include sizing open channels, reclaiming floodplains, creating lakes, or building other types of drainage-related facilities on major drainage courses. Design engineers of these types of facilities should be aware that the requirement of designing for fully developed watershed conditions will mean that they will have to calculate these Chapter 14 - Engineering Design Standards Page 14 - 28 Colleyville, Texas, Land Development Code fully developed flows instead of using the flows calculated in the Federal Emergency Management Agency's (FEMA) flood insurance studies for Colleyville or Tarrant County or from studies performed for or approved by the City of Colleyville. E. Desiqn Storm Frequencies - All developments submitted must provide data for the following design storm frequencies: 2-Year /5-Year /10-Year /25-Year /50-Year /100-Year. 1. Drainage facilities shall be designed in accordance with the following table: Closed Storm Sewer Systems ! 5-year with 1 DO-year positive overflow in streets i such that the depth of flow in the street does not , exceed the right-of-way or drainage easement ....Cios.edSlormSewerSystems \....{m~~2~iwith.positFveoveffiov:;m and Inlets at Street Low Point : g~_~_~9m.__.mm__m _.gl!ly~r,t~.'l.Il<:l...!=l..r..i.<:l9.~~.............. Concrete-lined Channels .................................H.H.H.......H.H......................... Earthen Channels 2. The approved drainage system shall provide for positive overflow at all low points and these areas must be denoted on the plans as such. The term "positive overflow" means that when the inlets do not function properly or when the design capacity of the conduit is exceeded, the excess flow can be conveyed overland along a grassed or paved course. Normally, this would mean along a street or alley, or shall require the dedications of special drainage easements on private property. F. Street and Alley Capacity 1. Streets - Streets and storm drains within new developments shall be designed so that storm water runoff resulting from a design storm of a one-hundred (100) year frequency is contained within the available right-of-way and/or drainage easement. The capacity of the street and right-of-way and/or easement and the storm sewer pipe working in combination must be designed for a capacity to safely contain a storm water from a design storm of one-hundred (100) year frequency. 2. Alleys - The flows created by the one-hundred (100) year storm shall be contained within the capacity of all paved alleys. G. Inlet Placement and Capacity - The storm sewer system is to begin at the point where the storm water from a five (5) year frequency storm reaches curb depth, with the exception of collector streets on which storm sewer facilities must be designed to prevent one-twelve (12') foot wide lane from ponding and on major streets on which storm sewer facilities must be designed to prevent one-twelve (12') foot wide lane in each direction from ponding. At such point where the combined capacity of the street and storm drain system satisfies the five (5) year street capacity criteria (as previously described) but the one-hundred (100) year frequency storm runoff can not be contained within the right-of-way additional pick-up points (inlet capacity) shall be provided along with an increase in storm sewer capacity so that the one-hundred (100) year frequency storm runoff will be contained within the right-of-way. 1. Inlets shall be placed upstream from an intersection whenever possible. At any intersection, only one street shall be crossed with surface drainage and this street shall be the lower classified street. When an alley intersects a street, inlets shall be placed in the alley whenever flow down that alley would cause the capacity of the intersecting street to be exceeded. 2. The minimum inlet size shall be ten (10') feet. No more than twenty (20') feet of inlet shall be placed along one gutter at any given location. Minimum sizes of laterals shall be twenty-one (21") inches for use with ten (10') foot inlets, and twenty-four (24") inch laterals with fourteen (14') foot, twenty (20') foot inlets, and drop inlets. Where laterals tie into trunk lines, place the laterals on a minimum angle forty-five (450) degrees and a maximum angle of sixty (600) degrees with the trunk line and connect them so that the longitudinal centers intersect. Chapter 14 - Engineering Design Standards Page 14 - 29 Colleyville, Texas, Land Development Code 3. Manholes are required every three hundred feet (300'). Junction boxes are required at every change in flow line direction, change in pipe size, and where a convergence of more than two pipes occurs. Manholes are to be five feet (5') square and can be precast or cast in place. H. Pipe Desiqn Standards 1. Storm sewer conduit shall be sized to flow full. Manning's Equation shall be used to determine the conduit size. 2. Design Velocities a. Minimum - two and a half feet (2.5') per second. b. Maximum - twelve feet (12') per second. c. The maximum discharge velocities in the pipe shall also not exceed the permitted velocity of the receiving channel or conduit at the outfall to prevent erosive conditions. The maximum outfall velocity of a conduit in partial flow shall be computed for partial depth and shall not exceed the maximum permissible velocity of the receiving channel unless controlled by an appropriate energy dissipater (e.g. stilling basins, impact basins, riprap protection). 3. In general, storm water shall be carried in concrete pipe conduit within the right-of-way but other types of conduit can be used to carry stormwater in areas other than the right-of-way. However, prior permission to use other conduit materials must be obtained from the Director of Public Works. 4. Hydraulic Gradient (also refer to the Ft. Worth Drainage Manual) a. Conduits must be sized, and slopes must be set, such that runoff flows smoothly down the drainage system. To insure this smooth passage, the hydraulic gradient must be at the proper elevations. The hydraulic grade line shall be established and shown on the plans for all storm sewer design. b. The hydraulic grade line shall in no case be closer to the surface of the ground or street than one foot (1'). The HGL must not exceed the neck into the inlet. c. Hydraulic gradient calculations shall account for all head losses that may occur in the storm sewer line. Friction head loss shall be determined by direct application of Manning's Equation. Minor losses due to turbulence at structures shall be determined using Appendix A of this section. 5. Inspection / Testing a. The compaction of backfill shall meet or exceed 95% Standard Proctor density. b. All storm sewer conduits shall be inspected prior to acceptance by the City. All conduit forty-two inch (42") or less shall be inspected using television inspection. Conduits larger than forty-two inch (42") may be inspected visually. c. A City representative shall be present during the television inspection. d.

All tapes and log sheets shall become the property of the City. I. Culvert Desiqn - Culverts must be designed using standard engineering practices and engineering judgment. Culverts shall be designed in accordance with the latest edition of the City of Fort Worth Drainage Manual. If the City of Fort Worth Drainage Manual does not incorporate the necessary standards please refer to the Texas Department of Transportation (TxDOT) Hydraulic Design Manual. 1. One (1') foot of freeboard is required between the one-hundred (100) year water surface elevation and the top of curb elevation. Exceptions must be approved in writing by the Director of Public Works. 2. Culvert hydraulic grade line calculations shall consider both inlet and outlet control. 3. Culverts shall be aligned to provide the minimum resistance to the flow of water during the 10, 50, 100 and 500 year events. 4. The maximum velocity through a culvert shall be fifteen (15') feet per second. 5. Stream stability shall be assessed when determining the number of barrels, height and width and culvert skew. Potential for scour shall be accounted for in the design. 6. Hydraulic jumps shall not be allowed from face of culvert to ten (10') feet from the culvert, subject to the approval of the Director of Public Works. Chapter 14 - Engineering Design Standards Page 14 - 31 Colleyville, Texas, Land Development Code J. BridQes - Two (2') feet of freeboard is required between the one-hundred (100) year water surface elevation and the low chord of the bridge. Exceptions to this requirement must be approved by the Director of Public Works in writing. 1. The skew of the bridge piers and abutments shall be oriented as close to the normal or flood direction of flow resulting in an angle of attack as close to zero (0) degrees as possible. 2. Bridge piers shall be aligned to provide the minimum resistance to the flow of water during the 10, 50, 100 and 500 year events. 3. Computer modeling programs used for the hydraulic analysis of bridges shall be HEC-RAS, Version 2.2, or HEC2. 4. Stream stability shall be assessed when designing the abutments and interior bents of the bridge. Scour shall be accounted for in the design. 5. Where flows are supercritical, erosion control measures shall be used in an area from one-hundred (100') feet upstream from a bridge to twenty-five (25') feet downstream from a bridge. K. Channels - Open channels may be used instead of an enclosed system when a pipe greater than an eighty-four (84") inch diameter (or other shape equivalent to more than thirty-eight and a half (38.5) square feet) is required to carry the design storm event. 1. Design Criteria: a. All open channel design must follow the Corp of Engineers Guidelines. b. Channels may be left in their natural state provided that the channel velocities are six (6.0') feet per second or less and that one (1') foot of freeboard is available during the design storm event. c. If the natural channel is to be replaced by an improved channel, the flow from the one-hundred (100') year design flood must be contained within the improved channel while allowing for one (1') foot of freeboard. d. Improved channels shall be trapezoidal shaped and include a lined section if the design velocity is greater than six feet per second. Lining types such as concrete, rock walls and gabions may be used upon approval of the Director of Public Works. The maximum velocity allowed in concrete lined channels is fifteen (15') feet per second. e. Unless shown to be feasible in a soils report sealed by a licensed professional engineer in the State of Texas, and approved by the Director of Public Works, improved channels shall have minimum side slopes of: (1) 4 feet horizontal to 1 foot vertical for earthen, grassed-lined side slopes. (2) 2 feet horizontal to 1 foot vertical for concrete-lined side slopes. f. Where practicable, all unpaved channels should have sufficient grade to avoid ponding. A minimum slope of 1.00% is required for earthen channels and swales, except those used as part of a wetlands area. In areas where 1.00% cannot be obtained a pilot channel approved by the City may be used. All lined channels are to have a minimum slope of 0.50% and earthen channels a minimum slope of 1.00%. g. The developer or owner shall use low maintenance vegetation for vegetative cover, as approved by the Director of Public Works prior to planting. The selection of materials shall comply with the current ground cover listing for North Central Texas furnished through the Texas Agricultural Extension Service. 2. Manning's Equation can be used to design channels and determine water surface elevations and Chapter 14 - Engineering Design Standards Page 14 - 32 Colleyville, Texas, Land Development Code velocities when backwater effects are negligible, subject to approval by the Director of Public Works. Channels where backwater effects occur must be designed using models accepted by FEMA. 3. All channel sections must consider and account for channel stabilization in their design. This requirement pertains to all sections whether they are left in their natural condition or are modified in any manner. The design of all drainage channels and swales shall assure adequate capacity and minimum maintenance to overcome the result of erosion, silting, sloughing of bends or similar occurrences. 4. When performing hydraulic analyses for channel or drainageway design, the one-hundred year (100) year starting water surface shall be based on the following: a. Known water surface elevations should be used where possible. Known elevations are available for some creeks and channels from previous studies approved by the City. b. When known water surface elevations are not available the slope-area method or a rating curve may be used. (1) A rating curve approximates the starting water surface elevation for a given flow by using the relationship between known flows and water surface elevations for the creek. This is an excellent method for determining starting conditions if good data is available to develop the rating curve. (2) The slope-area method approximates the starting water surface elevation by calculating the normal depth for the channel. To calculate normal depth the slope of energy gradient for the channel is required. The energy slope can be approximated using the average slope of the channel or the average slope of the water surface. 5. The design of the channel lining shall take into account the super-elevation of the water surface around curves and other changes in direction. In general a radius that is three (3) times the top width of the water surface during the design storm event is recommended for channel bends. 6. A chain link fence six (6') feet in height, or other improvements as approved on a case by case basis by the Director of Public Works, shall be constructed on each side of the lined channel. 7. Gabion or other forms of channel lining may be used in lieu of reinforced concrete lining with the approval of the Director of Public Works. L. Detention Desiqn - Runoff rates for all land uses shall be limited to the rates that would be produced from single family residential areas. This requirement also applies to the development of sites as churches, schools, and other institutional uses. Detention/retention facilities shall be designed for the fully developed one-hundred (100) year design flood according to the following criteria: 1. The minimum amount of storage volume of the detention basin shall be that volume required to reduce runoff rate during the one-hundred (100) year event to the undeveloped rate. The outflow structure shall be sized to reduce the 2, 5, 10, 25, 50, and 100 year discharges to the undeveloped rate. Dedicated detention/retention basins shall also include an additional one (1) foot of freeboard and two (2) feet of sediment storage. The volume of runoff storage for drainage areas greater than one-hundred (100) acres shall be computed using unit hydrograph procedures. Acceptable unit hydrograph procedures are provided in Section 14-170.D.1 of this document. For drainage areas less than one-hundred (100) acres, the above methods are recommended; however, an approximate routing method based on the modified rational method is allowable. 2. All detention facilities designed shall consider the timing of the flood peak in the main channel into which the detention facility drains. Delaying the peak from a site in lower portions of a watershed may result in a higher peak on the main channel. The Director of Public Works may require that upstream and downstream ponds be included in the detention design model. 3. A detention facility shall have enough gradient to ensure positive drainage to the outlet structures so Chapter 14 - Engineering Design Standards Page 14 - 33 Colleyville, Texas, Land Development Code as to avoid nuisance conditions such as standing water, odors, insects, and weeds. A minimum slope of 0.50% towards the outlet structure is required for all grass lined detention facilities. 4. Detention areas in parking lots shall not be: a. In required parking spaces. b. Behind speed bumps unless the speed bumps are made with reinforced concrete. c. Deeper than six (6") inches unless otherwise approved by the Director of Public Works. 5. Drainage easements shall be provided for all regional detention/retention facilities and for other detention/retention facilities where two or more owners are involved. 6. Individual detention facilities shall be designed to empty in less than three (3) hours, unless it is also serving as an erosion control facility. 7. Detention facilities used as a sediment control facility shall meet the following requirements: a. The sediment control facility shall be designed with minimal velocities such that sediment is dropped and not picked up by flows at any time during the storm event. b. The basin shall be designed with two (2) feet of sediment storage area so that sediment removal is not required more than twice a year. Expected removal periods greater than twice a year must be specified in the maintenance plan and approved by the Director of Public Works. c. Sediment control facilities cannot be used to meet detention requirements unless the volume of sediment is included in the calculations for the detention basin design. 8. The owner shall maintain detention/retention facilities unless the facilities are dedicated to the City of Colleyville. Detention facilities must be properly maintained if they are to function as intended over a long period of time. The following measures are required to ensure the facility functions properly. a. Facilities should be mowed at least twice a year to control weeds and discourage woody growth. b. Debris, litter and accumulated sediment should be removed from detention facilities at least twice a year. Particular attention should be given to removal of debris, litter and sediment around outlet structures. The Director of Public Works may require that the property owner remove said debris when in the Director's determination that property damage or a flood hazard may exist. c. Detention basins designed for sediment removal shall be maintained as specified in the maintenance plan and approved by the City with construction plan submittal. M. Flumes - The use of flumes is not recommended for widespread use. Flumes shall not be permitted when the purpose of a permanent flume is to carry runoff down the sides of earthen channels. 1. A flume may be used to direct overflow runoff along property lines until the runoff can be intercepted by streets or conduits. A flume shall not carry more than ten (10) cubic feet per second during the one-hundred (100) year storm event with a slope of 1.00%. 2. All flumes crossing sidewalks shall be covered or bridged such as to minimize danger to pedestrians. 3. All edges are to be protected with rock rip-rap or other form of protection for erosion control and scour purposes. N. Lakes - Approval to develop in any area subject to inundation by a lake must be obtained from the appropriate agency responsible for that particular lake before the city grants its approval. Agencies that should be contacted include U.S. Army Corps of Engineers, Tarrant County Water Control Board, TCEQ, the Trinity River Authority, and FEMA. Regardless of approvals obtained from those agencies listed above, no filling, development or Chapter 14 - Engineering Design Standards Page 14 - 34 Co/leyville, Texas, Land Development Code construction in any area subject to inundation by a lake shall occur without the approval of the City Manager. The City Manager may require any studies necessary to determine that filling, development or construction will not have a detrimental effect on adjacent, upstream or downstream properties and buildings. This subsection in no way diminishes other requirements of this section. O. Lot Drainaoe and Gradinq - Grading and drainage of all residential lots shall be designed in a manner which will allow one lot to drain across an adjacent lot and into a permanent structure, such as a concrete flume, lined channel, or proper inlet to an adequate drainage facility, or to a street right-of-way. If an approved drainage structure is not present, it will be required of the developer to construct the necessary facilities. (0-00-1261/12/19/00) 1. Sheet flow techniques shall be used for lot to lot drainage where possible. (0-00-1261/12/19/00) 2. Single lots shall accommodate their own drainage into an approved structure where topographic elevations allow this to occur. (0-00-1261112/19/00) Section 14-175 Miscellaneous A. Trench Safety - In conformance with House Bills 662 and 665 as passed by the Seventieth Legislature Regular Session of the State of Texas, all construction projects within the City of Colleyville or its extraterritorial jurisdiction as provided by the Municipal Annexation Act (Article 970a, Vernon's Texas Civil Statutes) shall contain provisions for trench safety. On construction projects in which trench excavation will exceed a depth of five (5) feet, the uniform set of general conditions must require that the bid documents and the contract include detailed plans and specifications for adequate safety systems that meet Occupational Safety and Health Administration standards and that these plans and specifications include a pay item for these same safety systems. B. Underoround Utilities - All distribution lines, cables, etc. for utilities other than those listed above shall be installed below ground within the subdivision. Transmission lines or major cables to provide utilities such as electric, telephone, and cable television to the area as a whole may be located above ground on the perimeter of the subdivision being served. The installation of these utilities shall conform to commonly accepted construction standards and be subject to review by the Director of Public Works. Section 14-180 Drainage Studies and Engineering Certification A. Preliminary Drainaoe Analysis Guidelines - The purpose of a Preliminary Drainage Analysis is to determine the need for drainage facilities and/or drainage easements either within the proposed development or offsite. A Preliminary Drainage Analysis is required for every subdivision plat or a development requesting a building permit on a parcel which does not have a previously approved drainage analysis, unless the Director of Public Works has waived this requirement due to existing conditions. The Preliminary Drainage Analysis shall consist of the following information: 1. A topographical map drawn at a scale of I" = 200' which depicts the watershed that drains to and across the subdivision or development. The map must include the subdivision and an area extending a minimum of 200' in all directions from the proposed subdivision. Sheets shall be either 18" X 24" or 24" X 36" in size and may contain sheet to sheet match lines. The map must include contour lines at five (5') foot vertical intervals in terrain with a slope of two (2%) percent or more, or two (2') foot vertical intervals in terrain with a slope of less than two (2%) percent. Data from the City topographic maps will be acceptable where available. Data from USGS Quad sheets may be acceptable only where City topographic maps are not available. The datum for "0" topography shall be that of the United States Coast and Geodetic Surveyor the City of Colleyville GIS datum. The map shall indicate any offsite or adjoining areas outside the limits of the area being developed which are relevant to onsite drainage. Show all significant physical features such as proposed or existing drainage and utility easements, water bodies, streams, railroads, parks, and drainage ditches. Show location of existing utilities including gas and petroleum lines, electric, telephone and Chapter 14 - Engineering Design Standards Page 14 - 35 Colleyville, Texas, Land Development Code TV cable. Also, the location of any existing structures located within the area being proposed for development. The plan shall include the building footprint and parking areas when the Preliminary Drainage Analysis is prepared for a building permit. 2. Calculation of the drainage areas, time of concentration, and storm water runoff rate for the 2, 5, 10, 25, 50 and 100-year frequency storms. The design calculations shall include preliminary locations of drainage facilities. (0-00-1261/12/19/00) 3. Identification of special flood hazard areas as defined by the Flood Hazard Area Regulations Ordinance and as located by the current Flood Insurance Rate Map. 4. The Preliminary Drainage Analysis shall be sealed by a Registered professional Engineer licensed by the State of Texas. B. Drainaqe Study Guidelines - A Drainage Study is required when it has been determined by the Director of Public Works that the area being developed will require storm water drainage facilities or drainage easements either within the development or offsite. The following criteria shall be used for the developer's engineer to prepare a Drainage Study. 1. The study shall analyze the effect of the subdivision or the development on existing downstream drainage facilities. The study shall be sufficient to verify compliance with the drainage design criteria contained in this chapter. 2. The study shall include a topographical map as defined above in "Preliminary Drainage Analysis Guidelines." 3. Delineation and calculation of drainage areas together with proposed flow arrows shall represent flow patterns from runoff after all proposed improvements have been installed. Surface water drainage patterns shall be shown for each and every lot in the proposed subdivision and for each lot adjacent to the proposed subdivision. 4.

Rodne, Library Director DATE: April 14, 2003 SUBJECT: Proposed Colleyville Public Library Circulation Policy In preparation of the Circulation Policy, staff reviewed comparable policies of local libraries. General basic guidelines included in most policies of libraries in this area were included in this policy. For this policy, several decisions have to be made. These include: loan periods for materials, item check out limits and fee charges. In consideration of the above, staff developed two charts: Circulation Materials Restrictions and Replacement and Processing Fees. In developing contents of these charts staff considered the following: 'jr Fees and circulation loan periods of area libraries 'jr Proposed collection size of the Colleyville Public Library On the basis of the above, staff proposed the attached Circulation Policy for consideration. COLLEYVILLE PUBLIC LIBRARY CIRCULATION POLICIES o BORROWING PRIVILEGES . ELIGIBILITY TO BORROW Individuals presenting valid Colleyville Public Library cards are eligible to borrow materials from the Colleyville Public Library when the following conditions are met: 1 . No materials which are more than one circulation period overdue on their card. 2. No outstanding fines in excess of the set threshold (Appendix A). The library staff may not waive these regulations without the specific permission of the Library Director or his/her designee; however, the patron may request and receive a 24-hour hold on the item(s) he or she wishes to check out to allow the patron to correct the situation, which has resulted in loss of eligibility to borrow. Waiver of these regulations will be granted only if proof of mitigating circumstances and proof of attempts to correct the situation are presented to the Circulation Supervisor or his/her designee. o LOAN PERIODS The library's basic loan period is 14 days. Materials excepted from the basic loan period may have loan periods of 3, and 7 days (Appendix A). Upon a patron's request, extended loan periods for vacations may be made at the discretion of a circulation staff member. Materials secured for a patron on Interlibrary Loan are governed by the circulation policies of the home library and must be returned to the home library on time. o LIMITS ON BORROWING The library reserves the right to limit the number of items in anyone subject area of anyone medium that may be checked out to an individual patron, on the basis of perceived demand for materials on that particular subject or in that particular medium (Appendix A). o RENEWALS Circulation Policy Revised 4/30/03 Page I of3 Most materials may be renewed, in person, by calling the Circulation Department or online by using the patron's library card number and Personal Identification Number (PIN). Library materials not reserved by another patron may be renewed for additional loan periods (Appendix B). Materials that are on reserve for another patron may not be renewed. Overdue materials will not be renewed without payment of any overdue fines. Interlibrary Loan materials that are overdue cannot be renewed. o DRIVE - UP WINDOW SERVICE The library has a drive-up window through which materials may be picked up during library operational hours. For this service, patrons need to call ahead and request staff to retrieve materials for window pick-up. o MATERIAL RETURNS The library has walk-up material returns inside the library and drive-up material returns outside the library. Patrons will be credited with the return of the item on the day it is put in the return. Items returned on a day the library is closed will be checked in the next day that the library is open. o OVERDUES Materials returned after their due date will be assessed an overdue fine (Appendix A) for each day the library was open between the due date and date of return. A fine will not exceed the replacement cost of an overdue item. Overdue notices will be sent out on the following schedule: 1st notice: 2nd notice: 3rd notice: after materials are 7 days overdue. after materials are 14 days overdue. after materials are 21 days overdue. If the materials are not returned one week after the 3rd notice is mailed, the patron will receive a letter revoking their borrowing privileges. o DELINQUENT PATRONS All borrowing privileges will be suspended if a patron accumulates fines in excess of the Library's threshold (Appendix A), or has unreturned materials for a period exceeding 21 days. Borrowing privileges shall be reinstated upon return of the materials and payment of the accumulated fees, or the payment of the replacement cost of the material and the accumulated fees. CIrculation Policy Revised 4/30103 Page 2 of 3 o LOST AND DAMAGED MATERIAL Borrowers are liable for the replacement cost of any library material lost, damaged or not returned. The charge for replacement shall be the cost of the material as noted in the item record of the Colleyville Public Library Online Catalog. A processing charge (Appendix B) will be added to all items. Borrowers who replace lost or damaged material with an exact copy will be charged a re-cataloging fee (Appendix B). Library staff will determine if the replaced material is an acceptable match. When material is returned with parts missing, the patron is responsible for the cost of the part (Appendix B). If the part is unavailable, the patron is liable for the replacement cost of the original material, plus a processing fee. o LOST AND PAID If a patron recovers library material that has been lost and paid for within one (1) month, the library will refund the cost of the material minus the processing fee. The returned material and the dated receipt of payment must be presented at the time of refund.

(See attached). To date, several of the projects have been completed. The Jackson Road and Cheek Sparger Road project is on hold. City resources will be used to complete the Cheek Sparger and San Bar drainage improvements. The Bedford Road and Saddlebrook Entrance project was funding with available MDUS funds for FY2002-03. Two of the projects (Jewell Estates and Stonecrest) required less funding than the estimates. Staff is proposing that the Drainage Bond Project List be amended to include funding for the Welsh Circle drainage and related paving improvements in the amount of $102,763. (See attached).

CITY MANAGER i I DEPARTMENT HEAD I I FINANCE REVIEW I ; Previous Action: None DEPARTMENT : ENGINEERING SUBJECT: Approval of a Construction Contract for the Welsh Circle Paving Improvement Project with J. L. Bertram Construction and Engineering, Inc., in the amount of $102,763 Reading and Public Hearing In February 2002, City Council approved a list of ten projects to utilize the $1.6 million in drainage bond funds. Over the past year some of the projects included in the original list have been constructed and completed below the engineer's estimates. This has allowed some additional projects to be considered for construction with the remaining funds. Staff met with citizens in the fall of 2002 at Welsh Circle and Montford Drive regarding standing water and improper drainage within the roadway. The current roadway has developed a sag in the gutter line and holds rainwater for weeks at a time until it evaporates. During the rainy season it will not dry up. The streets are asphalt and water has continued to undermine the road at this location causing deterioration of the subgrade, resulting in a greater problem. Construction will consist of removing and replacing the existing pavement with concrete and adjusting the grade to create positive drainage. All driveways, irrigation systems and mailboxes adjacent to the improvements will also be adjusted. Staff has met with the citizens and discussed the proposed improvements. Comments were received and addressed and the project was advertised in March 2003. Three bids were received and opened on March 25, 2003, with Boatner Construction Services being the low bid. However, numerous attempts to collect necessary background information and references from Boatner failed. Also, their bonding company is not listed with the U.S. Treasury; therefore, Boatner Construction Services was deemed non-responsive and the second low bidder, J.L. Bertram Construction and Engineering, Inc. was selected for consideration. The contract amount is $85,635.56 with a 20% contingency of $17,127 for a total of $102,763. A 20% contingency is needed due to the work being performed in a residential area. The City Attorney has reviewed and approved this contract.

DEPARTMENT HEAD I I FINANCE REVIEW i Previous Action: None DEPARTMENT: PUBLIC WORKS SUBJECT: Approval of an Interlocal Agreement with Tarrant County for Glade Road, Rose Street, Cherry Avenue, Lowrie Road and Reagan Road improvements, in an amount not to exceed $65,000 Reading and Public Hearing The City of Colleyville has entered into several interlocal agreements with Tarrant County in recent years regarding road improvements. Bransford Road south of L.D. Lockett (1999), Bandit Trail (2002) and including John McCain Road (2003). Each project was completed at a considerable cost savings to the City. The County provides all of the labor and equipment to conduct the improvements and the City is responsible for traffic control and material testing. Tarrant County is in the process of setting their summer construction schedule. The City has submitted to the County a list of roads that include: 1) the west end of Glade Road; 2) Rose Street; 3) Cherry Avenue; 4) Lowrie Road; 5) Reagan Road. The repair work will include the removal and haul off of the existing top course of asphalt, stabilizing, re-grading and re- compacting the subgrade and applying a 2-inch HMAC overlay. This type of project is a new addition to the City's annual street rehabilitation program and is consistent with the Colleyville Public Works Department procedures. The remaining street rehabilitation fund balance will be used this summer for repairs in other locations in which Tarrant County cannot participate due to workload issues. Financial Impact Funding is available from the Street Department Resurfacing Budget (001-33-6319). Recommendation Approval Attachments . Interlocal Agreement . Cost Estimate .

ABSTENTIONS ON ATTEST: CITY OF COLLEYVILLE: Cynthia Singleton, TRMC City Secretary Mayor CITY COUNCIL c\tYor CC~~ll AGENDA BRIEFING IL'X~S MEETING DATE: ' ITEM # : RESOLUTION # : 05106/03 13 R-03-2124 CITY MANAGER I DEPARTMENT HEAD FINANCE REVIEW I DEPARTMENT: COMMUNITY DEVELOPMENT SUBJECT: Reconsideration of the City Council action taken on a request for waiver of perimeter street improvement requirements on Lot 3R, Block 2, Thompson Terraces, located at 5009 Thompson Terrace Previous Action: Tabled 04/15/03 Update The City Council tabled action on this request when the applicant was called away from the meeting unexpectedly and was not available to finalize the discussion regarding his request for a waiver of the perimeter street improvement costs. Additionally, there was misunderstanding regarding the method for applying perimeter street improvement costs to reduce roadway impact fees. The property contains approximately 180 linear feet of street frontage, which after applying the per-front costs of $134.98, requires a perimeter street improvement cost of $24,295.50. Since Thompson Terrace is a collector street shown on the Master Thoroughfare Plan, the actual perimeter street improvement costs are used to reduce any applicable roadway impact fees collected at time of building permit. The applicant proposes to construct a new office building on the property containing 4,689 square feet, which would require the collection of a $12,107 roadway impact fee ($2,582 per 1,000 s. f. of floor area). State laws pertaining to roadway impact fees require developers be given credit against roadway impact fees for any perimeter street improvement costs. Thus, the roadway impact fee is reduced to zero, and the developer would pay the perimeter street improvement costs. The developer is requesting a waiver or reduction of the $24,295.50 perimeter street improvement costs. Reading and Public Hearing At the April 1, 2003, meeting, the City Council denied a request for a waiver of perimeter street improvement requirements for property located at 5009 Thompson Terrace. The applicant, Dr. Jonathan Richard, was not able to attend the April 1 meeting due to family medical reasons. He has submitted a letter asking that the City Council reconsider the request so he may present his case and discuss the issue with the Council. A copy of the letter is attached. Dr. Michael Richard is the owner of a lot located on the east side of Thompson Terrace, between Glade Road and Colleyville Boulevard. The owner submitted a minor plat of the property that created one non-residential lot for the construction of a medical office. The Planning and Zoning Commission approved the minor plat at the December 2, 2002 meeting. Agenda Briefing Resolution R-03-2124 Page 2 of 2 The owner is seeking a waiver of perimeter street improvement requirements for this property. Dr. Richard does not own any contiguous property, and a letter from the owner is attached that describes this request in further detail. The owner dedicated 1,350 square feet of right-of-way for Thompson Terrace on the plat. Thompson Terrace is identified for future widening on the Master Thoroughfare Plan, though no plans for improvement have been authorized. The future right-of-way for Thompson Terrace is 75 feet. Thompson Terrace is an asphalt street without curb or gutter. The future street would be constructed of concrete. The following tables show the pertinent data relative to this request. Perimeter Street Improvement Cost Estimate STREET FRONTAGE TOTAL ESTIMATE ACTUAL COST PER LINEAR FOOT Thompson Terrace 180.0 feet $ 24,295.50 $134.98 One of the responsibilities of a property owner when property is proposed for platting is to make improvements to adjacent streets if the streets are not currently constructed to City codes. Generally, streets are considered unimproved if the street is not concrete and does not have curb and gutter. Instead of improving the streets, the owner may escrow an equivalent amount of money with the City to meet this requirement. The escrow amount, which is based on the City's costs to construct a similar type of roadway, includes both construction and engineering design costs. Dr. Richard has appealed this requirement as allowed by the Land Development Code. The Land Development Code gives the City Council the authority to consider a waiver from this regulation, as the Council is the appeals body for Chapter 9 of the Code, in which this regulation is contained. The City Council's options in this case are the following: 1. Approve the waiver as requested - This action would waive the perimeter street fee requirement for this property in the amount of $24,295.50. 2. Approve the waiver in part - The Council may waive a portion or percentage of the fee. 3. Denv the waiver - The property owner must escrow $24,295.50 with the City before building permits could be issued on the property.

Box 185 Colleyville, Texas 76034 RE: Richard property on Thompson Terrace I am a long time resident of Colleyville and the current owner of the property at 5009 Thompson Terrace. At considerable time and expense I have endeavored to develop this property to better meet the needs of my patients and keep my practice within the city of Colleyville. As I have 3000 active patients coming to my office from over 12 nearby cities, the development of this property will be convenient for my patients and greatly enhance the visibility of other small business in downtown Colleyville and the nearby Villages of Colleyville. I submitted a minor plat to the City of Colleyville to combine two lots into one in order to build a small professional office building. The Planning and Zoning committee approved the plat at the October 12, 2002 meeting. After completing the platting process and donating the right of way to the City for future street improvements, I was surprised to find that I was still required to pay a $25,000 fee for additional improvements. As a solo practioner with a small medical practice, which requires over 80 hours per week of my time, this is a huge financial burden. Due to the increasing time and financial pressures of running a medical practice, had I known about this additional expense from the beginning, I probably would not have pursued the development of this property in Colleyville. I am concerned that further delay and additional expense may adversely impact my ability to meet the needs of my patients, therefore, I am requesting that the City Counsel grant a waiver of the perimeter street improvement requirement for this plat as allowed by the Land Development Code. . ~,erel~ J6nathan Richard, M.D. IR ErE' '''0' '. ,>-" . ~ : -".. r~m 12003 T I I... c ...< .-..... ... .': j 'l (I f rOll l (VIt,I ~,1~!

ABSTENTIONS ON PASSED BY A VOTE OF THIS THE DAY OF AYES, ATTEST: CITY OF COLLEYVILLE: Cynthia Singleton, TRMC City Secretary Mayor .~ Texas PLANNING AND ZONING COMMISSION MEETING MINUTES - MARCH 24, 2003 CALL TO ORDER Chairman Wall called the meeting to order at 7:00 p.m. ROLL CALL Commissioners Bruce Kelly, Earl Swift, Jeff Byerly, Bud Seller, Mark Jones, and Jeff Wall were present. Barry LeBaron, Clayton Husband, Jeff Jones, and Jan Levy from staff were present. INVOCATION The invocation was given by Commissioner Swift PLEDGE OF ALLEGIANCE APPROVAL OF MINUTES March 10,2003 Commissioner Swift moved to approve the minutes as amended to add a statement to the motion on item #4. Commissioner Byerly seconded the motion. The motion passed by unanimous acclamation. CITIZEN COMMENTS There was none. AGENDA ITEMS Chairman Wall announced that the applicant for agenda item 4 has requested that the Planning and Zoning Commission not take action on the case, but table the case do to the fact that the architect for the project would not be able to attend the meeting. He said it would not be fair to the people who came to speak about the case nor to the applicant to hold the public hearing since the applicant could not respond to the speakers. Chairman Wall moved to table item #4, Case Z-03-008, until the April 14, 2003 meeting. Commissioner Jones seconded the motion. The vote being: Ayes: Kelly, Swift, Byerly, Sellers, Jones, Wall Noes: None Chairman Wall advised staff to resend the notice of public hearing to the surrounding property owners. Planning & Zoning Commission Minutes - March 24, 2003 Page 1 of 8 Approved on Apri/14, 2003 1. Case P-03-008 - Minor Plat of Mockingbird Hill Addition, 10.6898 acres located on the west side of Pool Road in the 3400 block Clayton Husband presented the case to the commissioners and reviewed the staff briefing. There were no questions by the commissioners. Commissioner Kelly moved to approve the minor plat. Commissioner Swift seconded the motion. The vote being: Ayes: Kelly, Swift, Byerly, Sellers, Jones, Wall Noes: None 2. Case Z-03-006 - PUBLIC HEARING - Zoning Change from CN to PUD-R, 2.05 acres located at the northeast corner of Cheek Sparger Road and Steeplechase Drive Clayton Husband presented the case to the commissioners and reviewed the staff briefing. Commissioner Sellers asked Fire Marshal Jones if he was satisfied with the one entrance into the subdivision and about the turning radius. The Fire Marshal said the Land Development Code does not require more than one entrance for only ten lots and the houses are not required to have interior fire sprinkler systems. He said the street is not long enough to require a full turning radius in the cul-de-sac. Commissioner Jones said there are unique parcels in the city yet to be developed and he is in favor of bending a few rules in order to develop those properties; however, this proposal appears to be fracturing the rules. Staff responded there are other approved developments that have similar lot sizes. They mentioned the Villas at Caldwell's Creek and Westgate Villas; however, these subdivisions have open space and the proposed subdivision does not. Chairman Wall opened the public hearing. Those present wishing to speak were: Jimmy Schnurr, applicant. Commissioner Jones asked if it was possible to have open space in the subdivision. Mr. Schnurr said it was not economically viable. He explained that Boardwalk Homes is purchasing the property under commercial rates, yet they believe strongly the area is a residential area and not designed for commercial development. He said it is not a good commercial site as it has residential development on three sides. He explained there would be ten custom-built single family homes, with no two story structures, in the $300,000 range. Mr. Schnurr said the only access to the property is from Cheek Sparger Road since Bridlewood Estates owns the brick wall that runs along the western property line. He said that a commercial development on the property would generate more traffic than ten residential lots. He said he spoke with Bridlewood Estates, The Woods of Colleyville, Wood briar Estates and Saddlebrook Estates Home Owner Association representatives and the developer plans to mirror the Bridlewood HOA deed restrictions. He said this would be a high quality project that will benefit the area. Planning & Zoning Commission Minutes - March 24, 2003 Page 2 of 8 Approved on Apri/14, 2003 Commissioner Sellers asked about the positioning of garages. Monty Thomason, Vice President of Boardwalk Homes, explained this would not be a gated community and the average home would be approximately 2,400 square feet and start at $290,000. He said there would be no front entry garages, but they would probably have a front swing garage entry. Jo Ann Gasper, 4103 Paddington Way, said she would like the property to develop residential; however, there may be a line of sight problem when existing off Steeplechase. She expressed concerns about density and she encouraged the Commission to include the deed restrictions within the approving ordinance. Steve Knight, 3917 Felps Court, expressed concerns about commercial zoning in the area and said he believed that residential would be the highest and best use of the property. He said he has concerns about the density and said the developer commented that fewer lots were not viable because of the commercial rates. He said the developer should not pay commercial rates and he advised the Bridlewood homeowners to hold out for a better proposal for a residential subdivision on the property with fewer lots. He said they should not feel as if this is the only thing that could be developed on the property. Tom Caunitz, 4006 Steeplechase Drive, said his house would face the back corner of the development and he would be looking at the rear of houses. He said when he saw the pictures of proposed home designs, he thought there would be nice looking houses, but he is concerned about the number of houses. Pam Brandon, 3608 Briarbrook Court, said she is the president of the Woodbriar Homeowners Association and they discussed the proposal at a Board meeting. She said there are concerns about the speed of cars on Cheek Sparger and the number of accidents due to the curve in the roadway. She said something needs to be addressed about the road alignment for safety reasons. Steve Lingard, 301 Bridlewood South, said he lives on the corner on Lot 1. He asked questions about the distance from the fence to the rear of the houses, and about the proposal for a 112 story house on the rear lots within the subdivision. He said he did not want someone to have full view into his property. Mr. Lingard also expressed concerns about traffic and speeding on Cheek Sparger. Robert Peters, 4000 Steeplechase Drive, said he would also be facing the back yards of the proposed homes. He said he sent a letter to the commissioners proposing a different layout for the subdivision that will create a horseshoe drive around the houses. There being no one else present wishing to speak, the public hearing was closed. Commissioner Swift said he thinks that single family homes should be built in this area; however, he has issues about density, lack of open space, and the precedent it will set by creating such a high density with the adjoining property that still has the potential for being developed. He said this would be a big mistake. Planning & Zoning Commission Minutes - March 24, 2003 Page 3 of 8 Approved on Apri/14, 2003 There was discussion about the vacant lots in the area and the plans for development in the area. Commissioner Kelly said the Master Plan is currently being updated and they have no way of knowing what that plan will look like. He said the concerns about traffic are valid and if this property is developed, the traffic may turn out into an area of Cheek Sparger that needs to be aligned as required by a new Master Plan. Commissioner Jones moved to deny the zoning change. He said the area may be appropriate for residential development, but there are too many other issues with the request. Commissioner Swift seconded the motion. The applicant addressed the Commission and asked that the request be tabled so that they may continue to work with the surrounding neighbors and address their concerns. Commissioner Jones withdrew his motion. Commissioner Swift said he would not remove his second. It was determined that Commissioner Jones' withdrawal did not require Commissioner Swift to withdraw his motion to be valid. Commissioner Byerly moved to deny the zoning change. Commissioner Swift seconded the motion. The vote being: Ayes: Swift, Byerly Noes: Kelly, Sellers, Jones, Wall [Note: The motion to deny was not approved.] Commissioner Sellers moved to table the case until the April 14, 2003, meeting. Commissioner Jones seconded the motion. The vote being: Ayes: Kelly, Sellers, Jones, Wall Noes: Swift, Byerly 3. Case Z-03-007 - PUBLIC HEARING - Special Use Permit for an accessory building on 10.272 acres located at 816 L.D. Lockett Road Clayton Husband presented the case to the commissioners and reviewed the staff briefing. Chairman Wall asked staff how often a building that requires a special use permit is built without a permit. Staff responded that a building this size being built without a permit is unusual. He said the City's recourse is to require the owner to apply for a special use permit and go through the process of public hearings and if the special use permit is not granted, they would have to comply with the size regulations in the Land Development Code. Chairman Wall opened the public hearing. Those present wishing to speak were: Planning & Zoning Commission Minutes - March 24, 2003 Page 4 of 8 Approved on Apri/14, 2003 Marty Stajduhar, 101 Williamsburg Court, the applicant. He said he bought the land for the sole purpose of having horses and growing coastal hay so that he could get an agricultural tax exemption. Mr. Stajduhar said he used a contractor from Alvarado to build a covered area so that the horses could be ridden in all types of weather. He said the contractor informed him that a permit was not needed because the land was agricultural and used for agricultural purposes. Mr. Stajduhar apologized that he never talked to staff to confirm the information provided by the contractor. He said the information provided by the contractor made sense to him because of the lay of the land and the adjoining properties. He said there was a dilapidated house on the property that they tore down, but they left the pump room and have considered building a house on the property and living on the land in the future. He said there was no malicious intent, only misunderstanding. Commissioner Sellers asked Mr. Stajduhar about the covered arena. He responded that they now have loafing shed stalls and they want a closed area for the tractor and equipment. He said there is a 10' x 10' stone building that may be removed, and the structure that was built was not prefabricated. Lorraine Gohr, 809 Lavaca Trail, spoke in favor of the special use permit. She said since the Stajduhar's have purchased the property, they have cleaned up the property, have put in very safe fencing, and take excellent care of the property. She said they provide a facility that handicapped riders can use, and neighbors help with that endeavor. She said the Stajduhar's and the riding arena are an asset to the community and she wants the rural look to be maintained in the immediate area. She spoke about the enclave of rural uses that currently exist on Lavaca Trail and in the immediate area. Chairman Wall asked Ms. Gohr about the resale potential of her property because of the impact the size of this building has on her property. She responded that the area is clean and provides a wonderful service to the community and has no negative impact on her property, but only enhances the value of the neighborhood. Commissioner Kelly shared appreciation of the rural area of the neighborhood. Marty Gohr, 809 Lavaca Trail, spoke in favor of the special use permit. He said he is concerned about the higher density residential that is encroaching into this very special area of Coileyville. He said there are several nice properties in the area and they are diminishing because of the approval of recent higher density subdivisions like Westgate Villas. Mr. Gohr said the current use and the future intent by the Stajduhar's fit with the neighborhood. Andrew Mittag, 901 W. Lavaca Trail, spoke in favor of the special use permit. He said he has spoken before the commissioners on several occasions and they may have heard before how he moved from New York to Kansas and has now found the oasis in Colleyville on Lavaca Trail. He expressed the need to keep the area rural and how the frontage on Precinct Line will be developed as commercial, but the interior of the area needs to be maintained as rural. Mr. Mittag said he has three horses on his property and this structure does not bother him one bit. He said the Stajduhar's are an asset to the community. Planning & Zoning Commission Minutes - March 24, 2003 Page 5 of 8 Approved on Apri/14, 2003 Chairman Wall asked the Stajduhar's if the property is being used as a commercial venture. Mr. Stajduhar said no. He stated he operates a physical therapy clinic in Bedford, and his wife Lisa is certified to use horses as vehicles to help disabled people gain mobility. He said their family and the neighbors ride horses on the property and they have gate openings to the neighbor's property. There being no one else present wishing to speak, the public hearing was closed. Commissioner Swift told Mr. Stajduhar that he made a very good presentation and he now understands the request. He said the accessory building conforms to the area. Commissioner Sellers moved to approve the special use permit with a condition that the 10' x 10' rock building be removed in order to reduce the number of accessory buildings on the property. Commissioner Kelly seconded the motion. Commissioner Byerly said he does not have a problem with the motion but asked staff if they could put a provision in the ordinance that the removal of the building be given a deadline such as 45 days. Fire Marshal Jeff Jones said that technically a building of this size should have a fire sprinkler system. He said if the building is ever enclosed it would create a problem. Chairman Wall asked what other safety concerns the Fire Marshall had, especially if there were physically impaired people on the property. Jeff Jones responded that the building is all right if it is used as intended and as stated in the ordinance. He said if a building permit were ever applied for, they would reassess the use at that time. Chairman Wall expressed concerns about potential commercial uses on the property. Staff told the commissioners that commercial uses are not allowed unless authorized by the Land Development Code. Staff advised the use of the property is for riding horses, and the only issue the commissioners are considering is for the building proposed in the special use permit. Chairman Wall called for the vote. The vote being: Ayes: Kelly, Swift, Byerly, Sellers, Jones, Wall Noes: None 4. Case Z-03-008 - PUBLIC HEARING - Zoning Change from CC2 to PUD-R, 9.285 acres located on the south side of Centerpark, east of Colleyville Boulevard This item was tabled by the Commission earlier in the meeting. Planning & Zoning Commission Minutes - March 24, 2003 Page 6 of 8 Approved on Apri/14, 2003 5. Case Z-03-009 - PUBLIC HEARING - Amendment to the Land Development Code regarding notification requirements for Special Use Permits for alcoholic beverages Barry LeBaron presented the case to the commissioners and reviewed the staff briefing. There were questions by the commissioners regarding the current notice procedure and the proposed change. Commissioner Kelly said that if the 500-foot notification area was used, it might impede upscale restaurants from coming to Colleyville. He said there might be a red flag raised since no other communities in the area have this requirement. Chairman Wall opened the public hearing, and those present wishing to speak were: Jo Ann Gasper, 4103 Paddington Lane, spoke in opposition of the change in notification area. She said city staff does an excellent job of notification with the use of signs, notice to property owners, newspaper articles, and notice to homeowner associations. She said if they start with this exception, there might be other exceptions to follow. She said Colleyville needs to be on a level playing field with other communities in the area in order to attract businesses. She explained how the distance requirement was changed to comply with the State law in order to attract restaurants to Colleyville. Ms. Gasper encouraged the commissioners to recommend denial of the change. There being no one else present wishing to speak, the public hearing was closed. Commissioner Kelly moved to recommend denial of the change to the notification requirements for special use permits for alcoholic beverages. Commissioner Sellers seconded the motion. The vote being: Ayes: Kelly, Swift, Byerly, Sellers, Jones, Wall Noes: None 6. Discussion of the Master Plan Update. Appreciation to Barry LeBaron was expressed by the commissioners for all of his work that has been done. 7. Staff Comments, Reports and Discussion Items: None. 8. Commissioners' Comments and Reports: The commissioners asked for an update on the status of Bob Culley's request to be reinstated to the Planning and Zoning Commission. Staff informed them that Mr. Culley was asked to submit his application for appointment along with the others that would be considered by the City Council at the April 1 ,2003 meeting. He said advertisements for the opening had already taken place before Mr. Culley requested to be reinstated.

Barry LeBaron explained how commercial lots are not required to have frontage on a public street but are required to provide access from a dedicated access easement. He said these lots are accessible from a dedicated easement, which connects to both Colleyville Boulevard and Sanders Lane. Commissioner Culley moved to approve the minor plat. Commissioner Jones seconded the motion. The vote being: Ayes: Kelly, Culley, Swift, Byerly, Jones, Wall Noes: None Planning & Zoning Commission Minutes - April 14, 2003 Page 1 of 8 Approved on April 28, 2003 2. Case Z-03-006 - TABLED ITEM - Zoning Change from CN to PUD-R, 2.05 acres located at the northeast corner of Cheek Sparger Road and Steeplechase Drive Commissioner Jones moved to remove the item from the table for discussion. Commissioner Swift seconded the motion. The vote being: Ayes: Kelly, Culley, Swift, Byerly, Jones, Wall Noes: None Clayton Husband presented the case to the commissioners and reviewed the staff briefing. There was discussion by staff and the commissioners about the changes in the number of lots, the size of the lots, the density of the subdivision, and the plans to offer open space that will help in the realignment of Cheek Sparger Road. Mr. Husband distributed a larger size of the revised zoning exhibit that reflected the changes. He told the commissioners that a ten foot (10') wide trail is required along Cheek Sparger Road and the applicant has not asked for a waiver from the requirement. Chairman Wall moved to reopen the public hearing. Commissioner Swift seconded the motion. The motion passed by acclamation. Those present wishing to speak were: Jimmy Schnurr, applicant, told about how they took the issues that were problematic to the surrounding homeowners and redesigned the subdivision by reducing the number of lots, and adding some open space. He introduced the developer, Monte Thomason. Monte Thomason, developer, said he met with the Bridlewood Estates Homeowners Association and addressed the line of sight issue by placing open space along the southwestern portion of the subdivision. He said the proposed subdivision will have an entry feature that is compatible with Bridlewood Estates, they reduced the number of lots 20% from 10 lots to 8 and now offer approximately four dwelling units per acre. He said they redesigned the subdivision so that the smaller lots would abut the commercially zoned property to the east and the largest lots would abut the residential lots to the north. He said they now have a 45% reduction in paved area and they will limit the houses along Steeplechase and the two northern lots to one story and there will be three lots along the eastern side of the subdivision that will be allowed to have 1 % story homes. Mr. Thomason said they will exceed the Bridlewood deed restrictions and they will require 95% masonry coverage and no front-entry garages. He said there will be a HOA that will maintain all grass and landscaping and he plans on planting 15' to 17' live oak trees along Steeplechase to the west of the subdivision and they agree to the construction of a ten foot trail that is required along Cheek Sparger Road. He said they contacted Woodbriar Estates, The Woods of Colleyville, and the Saddlebrook homeowners associations to inform them of the proposed changes. Planning & Zoning Commission Minutes - April 14, 2003 Page 2 of 8 Approved on April 28, 2003 Commissioner Swift asked staff about the zoning and use of the lots to the east. There was discussion about the use of the property along Cheek Sparger. Commissioner Swift asked the fire marshal if he was all right with the reduction of paved area in the subdivision and Fire Marshal Jones responded that he did not have any problems with it and it is adequate for that length of street. Tom Caunitz, 4006 Steeplechase Drive, represented the Homeowners Association for Bridlewood Estates and said they met with the developer at the annual HOA meeting. He said they liked the changes and there are tremendous selling points. He said everyone at the meeting is in favor of a residential use for the property and the developer has worked with them to provide landscaping along Steeplechase. Pam Brandon, 3608 Briarwick Court, said she is president of the Woodbriar HOA and is in favor of the changes made by the developer. She said she spoke to four out of the six residents who live along Cheek Sparger Road as they would be most impacted by the development. She said they were in favor. D. J. Garmon, 3720 Oakbriar, said he was very concerned about traffic. He reported that people use Woodbriar Estates as a cut-through and they don't obey the speed limits or stop signs. He said he doesn't agree there would be more traffic generated by a commercial use than a residential development on the property. He said the density is still too high and Bridlewood Estates and the Woods at Colleyville were required to provide 20% open space. Steve Knight, 3917 Felps Court, spoke in opposition. He explained where he lived in relationship to the zoning change request. He said that density is a problem and sited the Sparger/Felps Addition as setting a trend in the area. He told the commissioners that Bridlewood's higher density was a result of the land being originally zoned multi-family and the desire of the citizens to have single family homes on the property rather than multi-family. He encouraged the commissioners to not keep scaling down the size of lots in Colleyville. He agreed that residential is the best use of the land, but still believes there is crunch room and the lots could be larger and fewer. There was no one else present to speak, and Chairman Wall closed the public hearing. Commissioner Jones moved to deny the zoning change as proposed. Commissioner Swift seconded the motion. There was discussion by the commissioners following the motion. Commissioner Culley said he agrees with the denial and the development needs more green belt and also density is an issue because the lots are significantly smaller than Bridlewood. Commissioner Byerly spoke about the need to jealously guard the adjoining commercial space and take a wait and see position in case commercial can develop in the area. Commissioner Kelly said even the representatives from Bridlewood supported reducing the density in order to have residential development on that property. Planning & Zoning Commission Minutes - April 14, 2003 Page 3 of 8 Approved on April 28, 2003 Chairman Wall called for the vote. The vote to deny being: Ayes: Kelly, Culley, Swift, Byerly, Jones, Wall Noes: None Chairman Wall explained that the case can go to City Council for consideration; however it will require a super majority approval vote to grant the zoning change request. 3. Case Z-03-008 - PUBLIC HEARING & TABLED ITEM - Zoning Change from CC2 to PUD-R, 9.285 acres located on the south side of Centerpark, east of Colleyville Boulevard Clayton Husband presented the case to the commissioners and reviewed the staff briefing. He told the commissioners that the applicant and representative are in attendance to make a presentation. Clayton said staff received two letters of opposition and they are in the commissioners' packets. Commissioner Jones moved to remove the item from the table. Commissioner Kelly seconded the motion. The vote being: Ayes: Kelly, Culley, Swift, Byerly, Jones, Wall Noes: None Kennis Ketchum, Portfolio Development, was present to represent the case. She spoke about the need for senior housing and presented statistics supporting her position. She said the buildings would have direct access garages and when they designed the architectural style, they were sensitive to what Colleyville is about and they didn't want to insult the community. Kennis said they will limit the buildings to one story where the buildings abut current residential and will and can legally restrict the rentals to seniors. She said the rents will be between $800 to $1,500 per month. Greg Faulkner, architect, also representing the land owner, showed slides of other similar projects that were developed in Dallas and other parts of the country. He explained the concept and how they try to keep the scale and luxury of single family homes and told about other amenities. Mr. Faulkner said there will be kitchen islands in some units and walk in closets. He said the streets will have names to give a sense of a single family development. He said there will be approximately 142 units and there will be entries off Centerpark and Colleyville Boulevard. He said that all cars will be required to be parked in garages; however they will provide guest parking. Commissioner Swift asked questions about the comparison of the proposed Colleyville project to the Hilton Head project that Mr. Faulkner's company designed. Mr. Faulkner said that the project was built in 1997 to 1998 and the projects would be similar in construction costs, but Planning & Zoning Commission Minutes - April 14, 2003 Page 4 of 8 Approved on April 28, 2003 the Hilton Head project would demand a higher rental cost, and the Hilton Head project was exclusively rentals. Commissioner Culley commented that the fronts of the buildings in the Colleyville design lack brick and masonry. Commissioner Jones questioned the marketing and research study that was performed and asked what brought the developer to Colleyville. Mr. Faulkner and Kennis Ketchum said that the owner has had no good commercial offers on the property and they felt there was a need to propose something different so that the property could be developed. There was discussion about why the developer is proposing rentals vs. sales. Mark Hiller, 6615 Brookshire, Dallas, Texas, owner of the property, said that Colleyville has a situation where parents are living with children and he felt there is a definite need for this kind of project for Colleyville residents. He said that he is not married to an apartment concept and would take the comments offered by the commissioners and consider condominiums. Commissioner Jones asked if the market study indicated that rents are more desirable than condominium ownership. Mr. Hiller responded that according to the economic part of the issue, rentals would be the first choice, but condominiums would not prohibit his interest in the development of the land. Andrew Wayne, 1009 Lakeridge, commented that the developer made a good presentation and said he is 57 years old and there is a need in Colleyville for senior citizen housing; however, the commissioners denial of the previous case because of density issues, negates approval of this item because it has an even higher density. He said there is a need for housing for seniors in Colleyville, but not a need for this type of living quarters. He said that this is not a marketing study provided by the applicant, but a professional study. He said there is very little greenbelt associated with the development and adding a minimum of 100 cars to Centerpark will affect all who live in the area. He said he is opposed to the zoning change. Dr. Susan Hess, 4609 Westbury Drive, said she lives in the Lakes of Somerset subdivision and has concerns that this development does not fit the ambiance of the area. She said density, and traffic concerns are a huge issue and there are better uses for the property. Don Shaver, 1001 Edgewater, said reports by City Council have stated that there are 57 seniors in Colleyville and he supposed those 57 seniors would not downsize to a two story apartment. He said nice garden homes with a lower density should be considered for the property. Ken Wallace, 4205 Green Meadow East, said he is in total opposition of the proposed zoning change. He said there should be no two story structures and has fears that in the future the property would not be maintained and it's value would decline. He said this may be a good concept, but not for where it is proposed. Larry Henry, 4104 Inwood Lane, said he is a 15 year Colleyville resident, and there is a need for more commercial tax producing businesses. He said this proposal is too disparate from the Planning & Zoning Commission Minutes - April 14, 2003 Page 5 of 8 Approved on April 28, 2003 Master Plan and the commissioners need to take time and understand the impact this proposal will have on the area. Margaret Sherlock, 905 Briar Ridge, said the City already has an apartment/town home project that was built by a Dallas developer who built two story buildings with the master bedroom upstairs and that was not a successful project. She spoke in opposition. Phil Charon, 4604 Clearwater Court, said his property abuts the east property line of the proposed project. He said that two story apartments are not designed for seniors. He said the developer has stated he proposes luxury apartments and when he compared rates along Highway 121, the average rental is $1.00 per square foot average. He said this proposed project is not a luxury apartment, but compares with average apartment rentals. He said that even though one story apartments are being proposed along the eastern property line, the finish floor elevations will rise to the west toward the flood plain and those buildings will overlook his property. He spoke about density and traffic problems and said this proposal is not suitable for Colleyville. Steve Ewing, 700 Green Meadow North, said he was on the Board of Directors of Saddlebrook HOA. He spoke in opposition due to density and the negative impact it would have on home values in the area. Ron Grove, 4708 Lakeshore Court, said there are so many boarded up businesses along Highway 26 and the addition of this type of project will degrade property values. Alan Jackson, 4801 Lakeshore Court, said most elderly people do not live in apartments. He said he pays three times the amount of taxes as in Keller, but does so willingly in order to live in a community that does not have these kinds of projects. He spoke about the negative impact the additional traffic and high density have and stated there is a place for this kind of product, but not here. Jim Gormley, 502 Green Meadow North, spoke in opposition sighting high density, lack of open areas and lack of green belts. He said Centerpark access is an issue as is the risk of seniors accessing off Colleyville Blvd. He said patio homes would be a great alternative with fewer units and one story buildings. Brad Trow, 4605 Colleyville Boulevard, said he owns the property where Riceland is located. He said although he relishes the idea of having so many hungry people nearby to support the restaurant trade, the property will become more desirable for commercial development when Highway 26 is widened. Kennis Ketchum, applicant, said that they appreciate all of the comments, and they are trying to come up with the highest and best use of the property. She said the owner has not been able to sell as commercial and they are proposing an alternative use. Chairman Wall closed the public hearing. Commissioner Culley commented that it appears the developer is here to make changes and work with the neighbors and he has never heard such productive comments at a public hearing Planning & Zoning Commission Minutes - April 14, 2003 Page 6 of 8 Approved on April 28, 2003 before. He said that Centerpark can handle more traffic and it can be regulated as the outgoing traffic from the day care center is regulated. He said that density is an important issue and apartments are not needed at this time in Colleyville. Commissioner Swift said that he is qualified to speak as a senior citizen. He spoke about current problems with a similar project, Spring Garden. He said that apartments don't fit the long term image of Colleyville and are counterproductive. He said he was very impressed with the image of Lakewood Estates and is sensitive to their comments. He said he did not believe it was legal to restrict rentals by age. Commissioner Kelly said that the comments by the citizens are not against development and growth in the area, but are against this type of proposal. He said it seemed as if the citizens and developer still want something to happen on the property. Commissioner Jones moved to deny the zoning change request. Commissioner Culley seconded the motion. The vote being: Ayes: Kelly, Culley, Swift, Byerly, Jones, Wall Noes: None Chairman Wall encouraged citizens to get involved with the Master Plan Update process. He said it seems as if the developer is willing to work with the community. [NOTE: The Planning and Zoning Commission took a 5 minute break and then resumed the meeting.] 4. Discussion of the Master Plan Update: Barry LeBaron said he is pleased with the positive feedback he has received regarding the meetings. He went over the upcoming schedule and outlined the process once the neighborhood meetings are concluded. Chairman Wall asked the commissioners to check their June and July schedules and notify staff so that meetings can be scheduled when most members can be present. There was discussion about comments raised in a Master Plan neighborhood meeting about the City pooling resources with the GCISD. Chairman Wall requested that staff meet with the new City Council and Mayor to update them on the Master Plan process with the Planning and Zoning Commission present. 5.

ZONING BOARD OF ADJUSTMENT MINUTES OF MEETING - MARCH 25, 2003 REGULAR MEETING: Chairman McNosky called the regularly scheduled meeting to order at 7:00 p.m. on March 25, 2003. Roll Call Present: Rich Munson, Skip Reynolds, Butch Bercher, Larry Henry, Dee McNosky, Ron Sturgeon, Pat Davis Staff: Tom Niederauer, Jan Levy, Eddie Edwards Approval of Minutes March 11, 2003 Butch Bercher moved to approve the minutes. Larry Henry seconded the motion. The motion was passed by a unanimous vote. Chairman McNosky explained the procedures of the Zoning Board of Adjustment and outlined the meeting format for the audience. She explained that approval of a variance requires four (out of five) affirmative votes by members of the Board. The five voting members were: Rich Munson, Skip Reynolds, Butch Bercher, Dee McNosky, and Larry Henry; however, the alternate members may enter into the full discussion of the case. AQenda Items Case A-03-003 - PUBLIC HEARING. Request by Larry Cole, Foxcreek Residential Development, I nc. for a variance from the fence setback regulations of the Colleyville Land Development Code at 401 Vintage Court, Lot 17, Block 5, Remington Park Addition, Phase III Tom Niederauer presented the case to the Board and reviewed the staff briefing. He displayed overheads of the location of the property, the site plan, and pictures of the property and surrounding areas. He said there was one letter of opposition included in their packets; however, three additional letters of opposition were received the afternoon of the meeting and copies of those letters have been made and distributed to the Board members and the applicant. There was a question about the location of the driveway on the adjacent lot at 6104 Remington Parkway. Staff informed the Board and showed a picture to indicate the driveway was located at the far end of the lot and was not immediately adjacent to the lot at 401 Vintage Court. Chairman McNosky opened the public hearing portion of the meeting. Those present wishing to speak were: Larry Cole, applicant, presented the case to the Board. He said he is the developer of Remington Park and also acts as the Chairman of the Architectural Control Board for the subdivision. He Zoning Board of Adjustment Minutes - March 25, 2003 Page 1 of 3 Approved on April 8, 2003 explained how this was a very unusually shaped lot that is impacted by having street setbacks on three sides and the owner, Peter Dibella, wanted to achieve some privacy in the back yard. He said seven of the eight board members on the Architectural Control Board viewed the plans and had no objections. He said they determined there would be no obstruction of view on the street and the aesthetics of the proposal was very important to the subdivision as a whole. He said the good side of the fence will face out and the Architectural Control Board agreed that they didn't want to look into the Dibellas' back yard. He said that Peter Dibella is a landscaper and what he will provide for landscaping will be very attractive and well maintained. Mr. Cole told the Zoning Board of Adjustment members that no neighbors spoke with him, as the developer of Remington Park, or the home owner, so they were surprised by the opposition and have not had time to talk with the neighbors who expressed opposition in writing, and did not attend the meeting to openly discuss their concerns. Pete Dibella, 401 Vintage Court, said there is a beautiful mature live oak tree on the lot closer to Vintage Court and they wanted to preserve the tree for the neighborhood. He said that is why they positioned their home as they did on the lot and they needed to build a home that is in the same style and size for the subdivision. He said they would like to build a pool off the patio as others have done in the neighborhood. Mr. Dibella said he will provide landscaping that benefits the neighborhood and he is open to adjusting the setback a little to provide for the landscaping. He said maintenance will not be a problem since he is in the business. Ron Sturgeon asked Mr. Dibella if he met with his neighbors, could a compromise be reached? Butch Bercher said there was a compromise offered in the packet with the possibility of using a wrought iron fence. Mr. Dibella said that privacy is an issue and the growth ofthe landscaping will not mature until three to four years to provide privacy. He said he has three children and it is very important to him that they have a fenced area to play in that is not visible from the street. Ron Sturgeon asked the applicant if he could split the difference from the setback he is asking for and the required setback and build the fence in that location. Larry Henry said there is possibility of the Board not granting a variance and before they get into negotiating a different setback for the fence, the Board needs to discuss the merits of the case. Larry Cole stated that originally he felt the less ground to be maintained outside the fence, the better it will be maintained. There was no one else present wishing to speak, and Chairman McNosky closed the public hearing portion of the meeting. Rich Munson said he drove around Remington Park and thought this was the only site where a solid fence would be adjacent to the sidewalk. He said the elevation of the street across from the fence, Chestnut Bend, would allow people coming off that street to have a clear view into the Dibellas' back yard. He said he saw another lot with a wrought iron fence around the pool, and he is not inclined to agree with a solid fence built in that area. Larry Henry said the Board needs to deal with the ordinances and constraints they are to work within. He said a wrought iron fence with shrubs as proposed by the letter writer does not present Zoning Board of Adjustment Minutes - March 25, 2003 Page 2 of 3 Approved on April 8, 2003 a good argument for the safety issue. He said when the shrubs fill in, there will be a solid barrier and that will be no difference than a wooden fence. Butch Bercher said the applicant did not receive the letters of opposition until just prior to the meeting and that puts the applicant and the board at a disadvantage because the neighbors did not appear at the meeting. Skip Reynolds said it is significant that the applicant has requested the Board to table the case, but the next time they appear before the Board he wants more information. He said he is troubled with the fencing issues because facing the house the way the applicant has, it disturbs the neighbors. He said there are three issues that are of importance and they are the safety issues, the aesthetics and property values of the neighborhood. He said there have been occasions and it is helpful if an applicant proposes a compromise plan such as a Plan A and a Plan B to the Board. He encouraged the applicant to look at other types of fences that would be appealing to the neighbors. Skip Reynolds moved to table the case until the April 8, 2003 meeting. Butch Bercher seconded the motion. Skip Reynolds amended his motion to include that the case may be tabled up to thirty days if necessary and the applicant will contact the City staff and advise them of the status of the request. Rich Munson seconded the amendment. The vote being: Ayes: Munson, Reynolds, Bercher, Henry, McNosky Noes: None ADJOURNMENT The meeting was adjourned by acclamation. They're being no further business, the meeting adjourned at 8:00 p.m. Respectfully Submitted, Jan Levy, Planning & Zoning Assistant Approved on: April 8, 2003 as written.
