2. PRESENTATION AND DISCUSSION
2a Presentation and discussion on the City of Colleyville Storm Drainage
System
Director of Public Works Jeremy Hutt presented this item and answered questions
of the City Council.
Councilmember Lindamood asked about the type of retaining wall at Martin
Parkway. Director Hutt replied some gable stone does exist at this location.
Councilmember Nakamura asked staff the location of this bridge. Director Hutt
replied at Martin Parkway, in the southern part of town, in between Cheek-Sparger
Road and Glade Road.
Councilmember Lindamood asked staff if the blocks in the channel at Jewel Estates
help to slow the flow of water. Director Hutt replied the slower flow was a
combination of opening up the channel, and lining the channel bottom, which
allowed the water to convey better.
Councilmember Lindamood asked staff if the water break blocks lined in the
bottom of creeks help to slow the water to help with drainage. Director Hutt
replied, relative to velocity control issues, you will see those in larger drainage
channels.
Councilmember Lindamood asked if staff has looked into something like that.
Director Hutt replied we have not looked at a product that would benefit that
particular scenario.

Councilmember Nakamura asked staff how many times a year the water crossings
close. Director Hutt replied at least once a month, but that is dependent on the
storms.
Councilmember Nakamura asked staff how much rain falls before the crossings are
closed. Director Hutt replied it depends on the amount of rain and the duration of
the storm.
Councilmember Lindamood asked staff if the headwalls around the crossings are
cleaned when the streets are cleaned. Director Hutt replied yes, anything in the
right-of-way is removed.
Mayor Pro Tem Putnam asked staff about the yearly expenditures. Director Hutt
explained the following slide:
Councilmember Lindamood asked staff if the excess goes into the reserve. Director
Hutt replied yes, any revenues over expenditures will add to the unrestricted net
position.
Councilmember Lindamood asked staff how long those funds have been
accumulating, the $1.6 million. Director Hutt replied since 1993.
Councilmember Taylor asked staff if the $956,550 is the revenue stream based on
the number of meters. Director Hutt replied yes.

Councilmember Lindamood asked staff if the property owner is only responsible for
the property line deeded to that property owner, relative to creeks. Director Hutt
replied yes, in conjunction with the maintenance of the parkway. The property
owner is responsible for keeping the area mowed and free of excessive debris and
trash.
Councilmember Lindamood asked staff if that would also include erosion control.
Director Hutt replied depending on what created the problem to begin with, the
property owner would be responsible for establishing the proper erosion control.
Councilmember Nakamura asked staff if the rain water had created the normal
wear and tear, would that be the City’s responsibility. Director Hutt replied when it
starts to interrupt the drainage and functionality of the drainage system, the City
would then step in.
Councilmember Nakamura asked staff if the modifications have been completed
with the Lakes of Somerset and Carmel Place Estates pond system. Director Hutt
replied yes.
Councilmember Lindamood asked staff if issues with the pond system created the
floodway change in the Carmel Place Estates development. Director Hutt replied
no.
Councilmember Short asked staff if siltation issues still exist. Director Hutt replied
no, there was a separation built between the two ponds.
Councilmember Nakamura asked staff when the Tara subdivision was built. A
member of the audience replied the early 80s.
Mayor Pro Tem Putnam stated the Tara subdivision does not have a fee based
HOA, and the creek issues are basically being impacted by privately owned
individuals. Director Hutt replied correct.
Mayor Pro Tem Putnam asked staff about the example of a neighborhood, along
the creek, that had a separate assessment completed. Director Hutt replied yes,
there are examples of HOAs that have had assessments completed to show the
impact to their HOA.
Councilmember Nakamura asked staff where the water and debris is coming from
to this creek. Director Hutt replied from rain, curb inlets, and fallen trees run into
that creek.
Mayor Pro Tem Putnam suggested taking the information back to the residents and
have a separate worksession to discuss the cost impacts, not only the precedence
it will set, given the 29 miles of creeks to maintain. He added there are a limited
amount of resources, but there may be options, such as increasing the fee.

Councilmember Nakamura asked staff if the Tara creek is the worst along the 29
miles. Mayor Pro Tem Putnam replied this is something that could be addressed
with the master plan. Councilmember Short stated his neighborhood had a similar
situation, and the residents put in money and an HOA assessment was completed.
Councilmember Taylor asked staff if this impedes the flow of the existing storm
water runoff, or is this just an unsightly area. Councilmember Nakamura
answered the erosion is coming up the back of those properties. Director Hutt
added the majority of the concerns are tied to the erosion side of it, and some
debris could accumulate over time and if not freed up, it could ultimately cause a
flow issue.
Councilmember Short asked staff about the options for a homeowner, in the
absence of City participation. Director Hutt replied some of the property owners
have looked at erosion control mitigation to offset or delay the issue.
Councilmember Short asked staff if there are regulations in place. Director Hutt
replied there are regulations the property owner would have to comply with, and
there are mitigation measures they could take on themselves, but they would have
to be in compliance.
Councilmember Lindamood asked staff who is ultimately responsible for keeping
the creek clean. Director Hutt replied the property owner is responsible; there are
no other policies in place.
Councilmember Nakamura asked the City Council if there are other property
owners in this same, unique situation, in which they cannot set up their own HOA.
Councilmember Taylor replied his neighborhood cannot establish an HOA without
90 percent property owner agreement.
Councilmember Lindamood asked staff if there is a small amount that we could
work with, not necessarily to accept responsibility. Director Hutt replied he did not
know.
Mayor Pro Tem Putnam asked City Council if they have any other thoughts on the
process to address the situation. Councilmember Short replied there is an idea of a
Public Improvement District (PID) that could be set up to collect money; or the
property owners may have to dedicate property along the creek to make the
property public.
Councilmember Taylor asked City Council if the property owners are willing to
deed over an easement to solve the problem. Mayor Pro Tem Putnam replied some
have said yes, in the context of talking about dedication of right-of-way for park
land.

Councilmember Short asked staff if the issue is with Little Bear Creek itself or
because of the other tributaries that feed into it. Director Hutt replied this
discussion is tied more to the section of Little Bear Creek.
Councilmember Nakamura asked staff if the City has staff who specializes in this
or an expert. Director Hutt replied yes, there are staff members for drainage, and
there are experts on natural drainage relative to creeks; however, there is not
someone on staff with the level of expertise who can do this day in and day out.
Councilmember Lindamood asked staff if this type of study would be included in
the 2019 master plan. Director Hutt replied yes, and a consultant will be chosen
who has this level of expertise.
Councilmember Lindamood asked staff if the master plan update could be moved
up and done now rather than later. Director Hutt replied it could be slated for 2017
or 2018, based on City Council’s direction.
Mayor Pro Tem Putnam suggested having a worksession with a limited topic of
Tara, to discuss options, cost impacts, and challenges the City may have, but with
solutions that would be doable, given the financial situation.
Councilmember Nakamura asked staff when the meeting with the Preservation
took place. Director Hutt replied June of 2015, and staff met with the developer
who built the infrastructure.
Councilmember Nakamura asked staff if it was with the current builder. Director
Hutt replied it was not, staff met with the original developer, who then sold off the
lots.
Councilmember Taylor suggested pre depth tests/measurements be taken of the
ponds, particularly the ones downstream to ensure those residents are not having
to pay for upstream development, and maybe done at the time of development.
Councilmember Lindamood asked staff if there is a moratorium on green tags until
everything is completely finished. Director Hutt replied staff is completing
extensive site inspections before green tags can be issued to ensure compliance
with the original development.
Mayor Pro Tem Putnam stated had some sort of process been in place in the
beginning, such as an escrow account, these issues could have been remediated
quickly on behalf of the impacted residents. Councilmember Taylor agreed and
stated that money could have been used to dredge the pond.
Mayor Pro Tem Putnam asked staff if anything like this is in place. Director Hutt
replied there was an escrow set up during the early part of development to

address dredging the Bridges at Riverwalk pond, which was specifically tied to the
PUD zoning case. He stated he is not aware of any cities where funds are set up
and allowed to be reimbursed over time based on completion.
Mayor Pro Tem Putnam suggested an action item to look at options.
Councilmember Nakamura asked staff what can be done. Director Hutt replied
staff is currently working with the HOA to determine predevelopment siltation
versus development siltation and once the data has been determined, enforcement
actions are being considered.
Mayor Pro Tem Putnam asked staff what the enforcement actions would be.
Director Hutt replied taking enforceable action before the builder is allowed to
proceed.
Councilmember Lindamood asked staff if moving forward ponds could be lined.
Director Hutt replied that is an option, but the fine siltation particles are still going
to get through erosion control.
Councilmember Nakamura asked staff if a liner would have helped the pond.
Director Hutt replied once the vegetation is established and the discoloration is
gone, and the homes and all of the construction is done, the pond should clear up.
Councilmember Nakamura asked staff when the project is scheduled to be
complete. Director Hutt replied the development is complete, but the homes are
still being constructed, and the completion of home construction is dependent on
when the last lot is sold. Councilmember Nakamura stated being concerned the
home builder will be gone before the issues are fixed.
Councilmember Nakamura asked staff if someone is going by the development like
they are supposed to be. Director Hutt replied staff performs post rain inspections,
as well as regular weekly inspections.
Councilmember Lindamood stated the Mayor wanted these issues to be resolved
before any green tags were issued.
Mayor Pro Tem Putnam asked Councilmember Lindamood what needed to be
done. Councilmember Lindamood replied the drainage issues and inlet covers.
Mayor Pro Tem Putnam asked staff where are we with the enforcement issues.
Director Hutt replied staff is working closely with the HOA relative to the pond, and
we are closely monitoring the home building sites with the active construction.
Mayor Pro Tem Putnam suggested for the next follow up session, there should be a
discussion about general enforcement policies and/or maybe define policies.

Councilmember Short asked City Council about expectations, noting you cannot
eliminate the pond being discolored. Councilmember Lindamood replied the pond
should have already established vegetation. Councilmember Short stated the
policy stuff in general or regulations. Councilmember Lindamood replied it is
important to have the SW3Ps in place to prevent this from happening.
Councilmember Taylor asked staff if the pond is collecting more than just from the
development. Director Hutt replied the pond is collecting from the development,
but the Bridges as Riverwalk pond is collecting from the curb inlets. He added the
Preservation pond will need to be dredged based on the amount of siltation
collected.
Councilmember Lindamood asked staff if the developer is responsible for dredging
the pond, even if the cost exceeds the $10,000 in escrow. Director Hutt replied
staff is looking for the appropriate enforcement action and the appropriate party
responsible.
Councilmember Short asked staff how often ponds need to be dredged. Director
Hutt replied it depends on the amount of contributing acreage, and construction
activity which contributes to runoff, as well as heavy rain events.
Councilmember Taylor asked staff if the builder will not get their last final until
there is a resolution with the pond. Director Hutt replied staff will have the
resolution before the last final is issued.
Councilmember Lindamood asked staff about the company who performed the
dredging. Director Hutt replied America Underwater.
Mayor Pro Tem Putnam stated the topics for a follow-up discussion include: the
timing of the master plan revision; a more tactical discussion about Tara options;
and the enforcement policy and maybe a more proactive approach to the
situations like the Preservation, or a mechanism to remediate on our own, without
having to serve as a go between with the developer.
