authorizes a municipality to adopt ordinances, rules, or police regulations that are for the good
government, peace, or the trade and commerce of the municipality.
2. Chapter 211 - Municipal Zoning Authority of the Texas Local Government Code, which authorizes a
municipality to divide a municipality into districts and, within each district, regulate the erection,

6.4. REQUIREMENTS
For any new commercial and institutional buildings or, additions, or alterations exceeding 50% of the
building improvement value based on the current certified tax roll , it shall be the duty of the administrative
official responsible for review of site plans to calculate the design score for all commercial and institutional
buildings as part of the building permit and site planning process. For institutional buildings, if no relevant
appraisal data exists on the certified tax roll, the building improvement value shall be obtained through an
independent third party appraiser, paid by the building permit applicant and provided to the City.
Paragraphs A through G are the basis for the design calculation to meet the requirements of the design
standards. The provided worksheet shall be attached to all commercial and institutional building plan
submissions for review. The final design will be evaluated by the staff on a pass/fail basis.

In order to determine that any two horizontal straight sections of wall in the same plane are

e. Any two or more same-plane wall sections which do not meet all of the requirements of
Paragraphs a, b and c above shall be determined to be part of one complete wall section.

B. Vertical Departure Variables (10 total possible points - See Figure 3 below)

s.f.
2. R= Total surface area of a projection of all sloping or vertical surfaces visible from the street
of the building relative to the four vertical planes of an imaginary cube which would enclose
the building. s.f.
For the purpose of the calculation of "R";
a. Buildings with principal wall sections which are generally rectangular must be aligned so
that principal wall sections are parallel to a face of the test cube.
b. Only those surfaces which slope at an angle of not less than 15 degrees nor more than
75 degrees from the vertical plane may be included in this area calculation.
c. Circular, convex or concave regular surfaces which are offset at the central point of the
curve by not less than one foot from the vertical surface and have a central angle of not
less than 60 degrees may also be included.
d. Q= Number of test cube vertical surface projections (1,2,3 or 4) visible from the street.
3. V= Vertical departure ratio or R/P =
4. Kv = Vertical Departure Score = 10 x V= Sum

a. The floor area of covered exterior balconies may be included. Attached canopies,
porches, verandas, and other shade oriented structural design features may also be
included.
b. The area under detached canopies shall be excluded.

D. Horizontal and Diagonal Roof Planes Variables (10 total possible points - See Figure 5
below)
1. F="F" as previously calculated in Paragraph A(2) above.
5%ofF=
2. E= Total visible horizontal and diagonal eave planes, ridge planes and/or parapet top planes
on the building.
For the purpose of this paragraph:
a. Two eaves in the same horizontal plane but which are separated by not less than 5
percent of "F" shall be considered separate planes.
b. Two parapets in the same horizontal plane but which are separated by not less than 5
percent of "F" shall be considered separate planes.
c. A parapet with a wall length of less than 5 percent of "F" shall be considered a
crenellation and shall not be counted as a parapet.
d. For every five crenellations, regardless of elevation, one equivalent plane may be added
to the calculation of total planes. In like manner, one crenellation shall equal 0.2
horizontal / diagonal planes.
e. For an eave, canopy or mansard which overhangs the vertical surface of the building by
not less than 18 inches, one plane shall be counted for the outer edge of the eave and
one plane shall be counted at the intersection of the eave and the wall.

f. One plane shall be counted for each diagonal ridge or edge of a sloped roof and, if the
edge is also an eve which overhangs the wall by not less than eighteen (18") inches it
shall be counted as two planes.
g. For mansards which wrap around a building corner, planes shall not be counted as
separate unless there are actual changes in elevation.
h. Two parapet tops which intersect at 90 degrees in the same horizontal plane shall be
counted as separate planes.
3. Q= Total # of surfaces visible from the street as identified in Paragraph B(2)(d) above.
4. H= Horizontal / Diagonal Planes Ratio or E/Q = Sum
