The Goodyear Tire & Rubber Company
General Location
The proposed Goodyear Tire & Rubber Company is bounded by Texas Avenue Frontage
Road on the northeast and by Brothers Boulevard on the southeast side . The site is at the
northwestern intersection of Texas Avenue and Brothers Boulevard . The legal descripti<.m is Lot
1 A, block 15 of Southwood Plaza, Phase One .
Property Description
The Goodyear site is a total of0.84 acres . Lot lA is currently unimproved grassland .
The proposed expansion will add 0.69 acres to the total impervious area.
Construction of this tract as a Goodyear Tire sales and service store is proposed by
0 . A. Kidd ofLondontown Properties. The land is zoned Cl and no change is proposed .
Primary Drainage Basin Description
The tract currently sheetflows at a slope of 1.3 % to 2.5% to the northeast onto Texas
Avenue Frontage Road which then flows into a ditch between Texas Avenue and the frontage
Road . The ditch flows in a southeastern direction under Brothers Boulevard through a 8' X 4'
box culvert. This culvert travels beneath Texas Avenue and discharges into Bee Creek,
Tributary A.
The tract does not lie in the 100 year floodplain, according to the F.E.M.A. "Flood
Insurance Study for the Brazos County, Texas and Incorporated Areas" on panel 22P .
Drainage Facility Design
There currently exists a detention pond adjoining this property to the west which has an
available capacity of93042 cf See Area Drainage Map . This pond services approximately 46.86
acres upstream including Wal-mart and Albertsons which contributes a maximum of 44298 .9 cf
at any time . Likewise GoodYear and surrounding areas contribute a maximum of 450 .7 cf during
any one minute increment. According to _routing calculations, this detention area is not currently
at peak storage capacity and will adequately detain Goodyear's excess runoff for a 100 year
storm . The peak storage currently in the detention pond at any time is 44408 .9. The maximum
depth of the detention pond without Goodyear's runoff is 2.83 ft ., and with Goodyear's runoff is
also 2.83 ft . The maximum depth does not reach 3 ft . and does not seal the 5' X 3' box culvert
passing beneath Texas Avenue Frontage Road .
A flume will provide runoff for the Goodyear site . See Site/Landscape Plan . Water will
flow across flume and drop over existing concrete wall into detention channel, similar to Sonic's
flumes . The 5' X 3' box culvert serves as a restricting device for the detention pond . Therefore,
water will not be restricted from the Goodyear site into the pond.

PURPOSE
This report has been prepared to present the findings of an investigation of the
impact on the existing detention basin in Block 15 of Southwood Plaza in College
Station, Texas, by the Albertson's Center proposed on Lot 4A in Southwood
Plaza phase two. This detention basin was constructed at the time of
construction of the Walmart Discount Center on Lot 3 in Block 15 of Southwood
Plaza.
LOCATION
This detention basin is located in Block 15 of Southwood Plaza phase one in
College Station, Texas, as described by plat recorded in Volume 1212, Page 483
of the Official Records of Brazos County, Texas. The detention basin is shown
as drainage right-of-way and is located immediately downstream of the· storm
sewer running through the Walmart parking lot in Lot 3 of Southwood Plaza. A
drainage map for. this project is included at the end of this report showing the ·
entire drainage area and the travel path for storm water. ·
DRAINAGE AREA
· The drainage area upstream of this detention basin consist of approximatelY. 44
acres of partially developed land that is zoned general commercial (C-1 ). It is
bounded generally by Hilltop Drive, Airline Drive, F.M. 2818 and Brothers
Boulevard. The existing land uses are a U.S. Post Office, an auto repair shop
and service station, a branch bank, a neighborhood convenience store and a
Walmart discount store. Approximately 18.4 acres is presently undeveloped, but
12.2 acres of that is the proposed Albertson's Center.
HYDROLOGICAL CONSIDERATIONS
The rational formula for calculating stormwater runoff will be used since the area
is less than 50 acres.
Table 11-1 on page 23 of the Drainage Policy and Design Standards for the City
of College_ Station, recommends a runoff coefficient of between 0.35 and 0.45 for
natural grasslands that slope between 1 % and 3.5% and a runoff coefficient of
· between 0.65 and 0.75 for Business/Commercial land uses. The land slope in
_.this drainage basin is within the 1 % to 3.5% range.
· When the Albertson's Center is completed, the drainage basin will have 37.8
acres of Business/Commercial and 6.2 acres of undeveloped natural grassland.
Assuming a runoff coefficient of 0.7 for Business/Commercial and a runoff
coefficient o_f 0.4 for undeveloped natural grassland, the following calculations
show that a w~ighted runoff coefficient of 0.66 can be used for the total drainage .

Shed Flow
Sheet flow is flow over plane surfaces. It
usually occurs in the headwater of streams.
With sheet flow, the friction value (Manning's
n) is an effective roughness coefficient that
includes the effect of raindrop impact; drag over
the plane surface; obstacles such as litter, crop
ridges, and rocks; and erosion and transportation
of sediment. TilCsc n values arc for very
shallow flow depths of about 0.1 foot or so.
Table 3-1 gives Manning's n values for sheet
flow for various surface conditions.
For sheet flow of less than 300 f ect, use
Manning's kinematic solution (Overton and
Meadows 1976) to compute Tt:

where
T t = travel time (hr),
n = Manning's roughness coefficient (table 3-
1),
L = flow length (ft),
P 1 = 2-year, 24 -hour rainfall (in), and
s = slope of hydraulic grade line (land slope,
ft/ft).
This simplified form of the Manning's
kinematic solution is based on the following: (1~
shallow steady uniform flow, (2) constant
intensity of rainfall excess (that part of a rain
available for runoff), (3) rainfall duration of 24
hours, and ( 4) minor effect of infiltration on
travel time. Rainfall depth can be obta1ned
from append.ix B.
Shallow concentrated flow
After a maximum of 300 feet, sheet flow
usually becomes shallow concentrated flow.
The average velocity for this flow can be
determined from figure 3-1, in which average
velocity is a function of watercourse slope and
type of channel. For slopes less than 0.005 ft/ft,
use equations given in append.ix F for figure 3-
1. Tillage can affect the direction of shallow
concentrated flow. Flow may not always be
directly down the watershed slope if tillage runs
across the slope.
After determining average velocity in figure 3-
1, use equation 3-1 to estimate travel time for
the shallow concentrated flow segment
Open channels
Open channels arc assumed to begin where
surveyed cross section information has been
obtained. where channels arc visible on aerial
photographs, or where blue lines (indicating
streams) appear on United States Geological
Survey (USGS) quadrangle sheets. Manning's
equation or water surface profile information
can be used to estimate average flow velocity.
Average flow velocity is usually detcrmmed for
bank-full elevation.

Approximately 7 acres of highway right-of-way contributes stormwater runoff to
the drainage ·ditch immediately downstream of the detention basin outlet.
Another approximately 8 acres is upstream of the intersection of Brothers
Boulevard and Texas Avenue. Table 1 above is a tabulation of the runoff ·
quantities for the various areas for different storms.
HYDRAULIC CONSIDERATIONS
As presently constructed, the detention basin discharges through a rectangular
reinforced concrete channel under the Texas Avenue frontage drive. The .
channel has a 5' . bottom width and is 3' deep below the frontage drive. The
channel slope under the frontage drive is approximately 1.75%. Manning's
equation for op.en channel flow gives a a of 259 cfs with a velocity of 17 ~3 fps.
At this depth, the volume of detention is approximately 44,000 cubic feet or
about 1 acre foot. With a depth of flow of 2.75 ', the outlet a -180 cfs, V=13 fps
and the volume of detention is approximately 39,000 cubic feet or 0.89 acre feet.
_...,.z;.::..;.;•,. ···-· .
.. .. .. 6
Discharge from the detention basin Is into a drainage ditch between the frontage
drive and the main lanes of Texas Avenue. Downstream of the detention basin
outlet, the flow is through an 8' X 4' box culvert under Brothers Boulevard. The
difference in elevation from the top of pavement over this box culvert to the
flowline is 4.66 feet. The pavement rises 1.0 foot from the top of the box culvert
to the centerline of Texas Avenue approximately 80' away and slopes up at
2 .22% (45:1) back along Brothers Boulevard to the southwest.
The maximum flow through the 8' X 4' box culvert before flowing over the
Brothers Boulevard pavement is approximately 200 cfs which is shown on the
following tabulation of a Box Culvert Analysis Computer Program by Dodson &
Associates, Inc. This agrees with the highway department calculations shown
on the plans for the widening of Loop 507 (Texas Avenue) dated December 18,
1984.

If stormwater is allowed to flow over the Brothers Boulevard Pav·ement, the
drainage ditch will provide additional detention volume. Assuming the pavement
· section over Brothers Boulevard to be a trapezoidal channel with a 45:1 side
slope right and an 80:1 side slope left, a Manning's n value of 0.018 and a
bottom slope equal to the box culvert of 0 .25%, the following tabulation show the
quantity that will pass at various depths over the pavement.

Assuming the present stage of development upstream of this detention basin
plus the development of the Albertson's Center, a 100 year storm would produce
196 cfs of stormwater discharging into the detention basin from the Walmart
stromsewer. Adding to this approximately 19 cfs from the highway right-of-way
upstream of the outlet and another 22 cfs from the 8 acres downstream of the
outlet gives a total of 237 cfs at the culvert under Brothers Boulevard. Assuming
a 2. 75' depth of flow at the detention basin outlet, there will be a discharge of
approximately 180 cfs. This discharge plus the 41 cfs from the two down$tream
areas will produce 221 cfs at Brothers Boulevard which would overflow the street
approximately 6" deep. Results of a computer model of this condition is shown
on the following page.

The required · storage volume of 0.66 acre feet is less than the available 0.89
acre feet at .the 2. 75' depth.
Assuming full development of the drainage basin upstream of the culvert at
Brothers Boulevard and a time of concentration of 15 minutes, a 100 year storm
will produce approximately 300 cfs entering the detention basin from the
Walmart stormsewer, 55 cfs from the 8 acres discharging downstream of the
outlet and 27 cfs from the 7 acres of right-of-way upstream of the outlet. If the
9
outlet channel flows 3' deep, there will be a discharge of approximately 259 cfs
from the detention pond. This produces a quantity of 341 cfs at the Brothers
Boulevard culvert and will overflow the pavement between 0.9' and 1.0' which
will not overflow Texas Avenue. Computer output of a model for this situation is
produced below.

CONCLUSION
Results of this study show that the present detention basin in Block 15 of
Southwood Plaza is more than adequate to contain the excess stormwater from
a 100 year storm after construction of the Albertson's Center with all other parts
of the drainage basin at present conditions. When all parts of the drainage area
are developed, the present detention basin will still detain enough stormwater to
prevent the overflow of Texas Avenue. This should be adequate during a 100
year storm, since adjoining structures are well above this elevation. The real
estate office downstream of Brothers Boulevard has a floor elevation of 3' above
the centerline of Texas Avenue at Brothers Boulevard and the Sonic Drive-Inn
has a patio slab elevation 3.5' above the top of pavement at the detention basin
outlet.

Re: Lot 1A, Block 15, Southwood Plaza
Certificate of Occupancy Permit #94026 71
Dear Veronic:
I sent an application for variance on the sidewalk
situation to the Texas Department of Licensing and
Regulation and received an answer today by phone
and I quote:
(1) "The sidewalk is not an accessibility
route to the building and therefore
is not an enforceable issue.
I asked her for this in writing and she said they
did not give written notices when not an enforceable
issue.
If the above answer does not satisfy your requirements
so that we can get a Certificate of Occupancy, please
use this lett er as my certification to you that in the
event any Government Agency who represents the ADA Act
comes forward and states the sidewa lk is to be torn
out and replaced, I will pay for such costs.
As for as the Certificate of Occupancy is concerned,
I need a new one without exceptions.
Please call me if you have any questions.
Very truly yours,
~

Re: Go odyear Bldg . in College Station located on
Te xas Avenue. Your letter of 9 -2 8-95 .
Dear Ms . Morgan:
I have tried for weeks to find out who sh ould be
respons ible for the sidewalk at the new Goodyear
Store not meeting the A. D. A. requirements. I
would like to relate to you my findings .
Let ra e begin with when I first found out that I would
be building a store for Good~ear in College Station,
I decided to ·use an Engineering firm in College
Stati o n who had worked with the City and was familiar
with requirements . In conversation with . the Seller
of th e land that I purchased, I was told that Municipal
Devel o pment Group (Gregory Ta ggart ) did a lot of work
for t he C~ty and this firm would be recommended to do
whatev er work that was needed.
To ma t e a long story short, Gre g ory Taggart with
Munic ip al Development Group developed a site plac for
the p r oject (which did not include a sidewalk because
he said that one would probably not be required) and
he sutm itted · the drawing (site plan) to your office
and a permit was issued for us to b egin the site work
which included the driveway. Driveway and all concrete
work ~as performed since ~e had a permit to do so.
What h appened next was that a meeting was h eld which
you (Veronica ) and Gregory Tag g art were in attendance
and i t was decided that all new construction was to
have a sidewalk. This information was related to me
by Ge r ald Prickette, the Builder.
He ( GE-rald Pricke t te) were told by your off ice that we
had t c put in a sidewalk. There was never a men~ion
that t he driveway had to be torn up and replaced or
that t he sidewalk had to have a slope at the driveway
to me E t A . D. A. standards.

The bLilding was completed in January and to our
surpr i se a conditional Certificate of Occupancy was
issued with the stipulation that the driveway apron
be to r n out and replaced to meet A. D. A. standards.
When e received the Certificate, Gerald Prickett e
had a conversation with you concerning the circumstances
that I now bring to your attention and you a dmitted to
him t h at Municipal Development Gr0up should be made to
r€pai r the driveway. In your discussion (according to
Gera l d Prickette) you indicated that you ·would talk
to Gr e g ory Taggart about the problem and see if they
would do the repairs. You indicated to him that
Munici pal Development Group performs a number of
servi c es for the City of College Station and you would
lean e n him to do the repairs.
Goody Ear Tire and Rubber Comp&ny has expressed to me
that this is the best construction job that I have
perfo r med ·for them and I have done stores from Conroe
to the Valley. They are happy with the driveway as it
appears and if I understand what you are requirin g ,
you a r e askin g for the sidewalk to b:e raised appToximately
1 1/2 " frorn the curb to level out the s idewalk which
accord ing to the Contractor, this is g oing to .cause
a s -it ation like a "sp~ed bump" for Goodyear customers
who i n g re,ss and egress fror:1 the property.
This d is r uption in business at the Goo d year store is
net n · cessary and has been created because of communications
betwe e n your office, Municipal Development Group and my
Build e r. I have received a cost of $5,000.00 to do the
requi red -work and I feel that your office (because you did ·
appro ~e th e site work plan a n d allowed us to do all of ·
the s i te wod< including paving) should share sor.1 _e of the
respo n sibility.
I the r efore request tha t a var iance be issued in lieu of
the r e pairs that you are askin g to be made and a
Certi f icate of Occupancy be issued to Goody e ar without
bein g conditional.

letter to oa kidd October 9, 1995
Dear Mr. Kidd:
I appreciate your letter of October 4, 1995 and I understand that you do not wish to repair the driveway and instead
desire to pursue a variance procedure to the requirement. I have called the A.D.A . Technical Assistance Center
about the matter and will update you as I get further information. In the meantime, I would like to clarify a few
things in yo~ letter, which in my opinion were incorrect or misstated .
First, in your letter, you stated that Gregory Taggert with MDG developed a site plan for the project (which did not
include a sidewalk because he said that one would probably not be required).
I have included for your reference a copy of the Project Review Committee report from a meeting held on July 13,
1995 . The second item on the list is the statement that a sidewalk is required along the Texas Avenue frontage
road as per the Sidewalk Master Plan . And it outlines the procedure for you to request a variance. This report was
mailed to both you and Mr. Taggert.
Secondly , you stated that what happened next was that a meeting was held which I and Gregory Taggert were in
attendance and it was decided that all new construction was to have a sidewalk .
I have included for your reference a copy of a letter from Gregory Taggert of MDG, requesting a variance to the
sidewalk, dated July 15 , 1994 . Also included is a copy of the Planning and Zoning Commission meeting minutes
dated August 4, 1994 , in which the Commission denied the variance request. I can only assume that the meeting
you referenced, where Greg and I were in attendance and decided that Goodyear was to have a sidewalk, was the
Planning and Zoning Commission meeting . I did not decide that Goodyear was to have a sidewalk, I merely made
recommendations to the Commission, who ultimately made that decision .
Third, you stated that there was never a mention that the driveway would have to be torn up or replaced to meet
A.D .A. standards.
MDG was aware that the sidewalk and the driveway, which it crossed , would have to meet all A.D.A. standards.
The building permit for Goodyear was issued on August 19 ,1994, well after the decision was made that Goodyear
would have to build the sidewalk . So at that point, there were no driveways poured. In fact, the original building
permit set even had a note that the site was approved for permitting except the driveway and sidewalk along Texas
Avenue which were pending TexDOT approval . Because both of these are within the State's right-of-way,
e a to approve the construe m o inio MDG set the grades on the site plan, relying on the fact
that the sidewalk variance would be approved . When it was not, MDG put together a sketch of the sidewalk, but
did not revise the grades through the driveway to meet A .D.A. requirements .
Fourth, you stated that I had a conversation with Gerald Prickette concerning the circumstances and that I
admitted to him that Municipal Development Group should be made to repair the driveway.
What I explained to Mr. Prickette was that the sidewalk variance was denied well before the driveway was poured
and if he found that the constructed grades matched the drawing provided by MDG that he should contact MDG
about the problem. When he stated that he was not on good speaking terms with MDG, I offered to contact Mr.
Taggert regarding the driveway to ask him to evaluate the problem . I explained to Mr. Prickette that this was as
much as I could do , as the responsibility of the final product lay with the owner, not with the designer. I indeed
contacted Mr. Taggert and he indicated that he would take some grade shots at the site to see what happened.
Shortly following this , he indicated to me that there was a contractual disagreement between MDG and Goodyear
•
and at that point discussions regarding Goodyear with me ceased . At that point I continued discussions with you
and Mr. Prickette regarding the repair. For several weeks both of you gentlemen indicated that you were trying to
come up with ideas to solve the problem. I even had several contacts from contractors regarding the problem, so it
was apparent to me that you were indeed working on a solution.
Fifth, you stated that Goodyear Tire and Rubber Company has expressed to you that this is the best construction
job that you have performed for them .
I would agree that the site construction is very good , and have no doubt that Goodyear's comments are warranted .
I would also add, however, that if the correction is not done carefully, you may very well switch the problem from a
sidewalk/driveway apron that does not meet A.D .A. to a driveway where cars will "bottom-out" and may cause a
safety concern in that regard . A well-designed solution can accommodate both concerns .
Sixth, you stated that because the City did approve the site work plan and allowed you to do all of the site work
including paving , that we should share some of the responsibility .
Our approval does not indicate that the City has checked every and all grades that are set on the site plan or all
construction details. It is the designer/owner's responsibility to assure that the design conforms to all City , State
and Federal regulations . Your designer should have assured that the grades met A.D .A. and it is not the City's
responsibility to check all design computations, especially when we do not receive design notes .
The way I interpret the chronology of events is as follows :
July 13 , 1994
staff
Goodyear was required to have a sidewalk at the very first meeting with city
July 15 , 1994 MDG requested a variance to this and proceeded with plan review pending the
outcome of the variance hearing
August 4 , 1994 The sidewalk variance was denied by the P&Z
August 19 , 1994 Building permits were issued witl1 a note excepting the driveway and sidewalk
on Texas Avenue frontage pending TexDot permits
September 1, 1994 TexDot permits for sidewalk and driveway approved
January 26, 1995 A conditional certificate of occupancy issued to Goodyear (condition based
upon the driveway apron where the sidewalk crosses being replaced to meet ~ A.D.A.)
I hope this chronology clarifies some of your concerns . It does illustrate to me that the sidewalk was not an "after
thought" and was discussed up front and openly through the entire design and construction process.
I understand your concerns regarding the potential use of the sidewalk by handicapped individuals. You have
stated to me on a number of occasions that you doubt a handicapped individual will ever use this sidewalk and it
would be hard to make this repair when it may never or only occasionally be used by these types of individuals. I
know that your statements were not meant in any way to be callous toward handicapped individuals, but the bottom
line is that the A.D.A. standards were put in place to assure equal treatment toward individuals with disabilities
and whether it may be one individual or many who may benefit from this sidewalk, it is my obligation to see that it
is enforced. It is also my obligation to afford to you any variance procedure available to you . As stated earlier, I
have contacted the A.D .A. Technical Assistance Center and will be back in touch regarding the possibility of a
variance to this situation . I hope my letter has clarified the history of this situation.
Sincerely,
Veronica J.B. Morgan, P .E .

Re: Goodyear Tire Store Site
Dear Jane :
After consultation with our client, 0. A . Kidd, we are officially asking that the sidewalk requirement
imposed on us by the PRC be lifted. Some of the numerous reasons which are immediately obvious
upon critical inspection are:
1) The sidewalk will be a "sidewalk to no where." No other sidewalk exists on this entire stretch of
Texas Avenue. Sonic does not have it; the establishments to the south don't have it. What
useful, practical pedestrian mobility is provided to the citizens of College Station by a 215'
sidewalk which dead ends into a drainage ditch? This seems to be a situation where the master
plan, while generally pertinent to the entire city, does not make sense in this particular
application.
2) The current requirement is unfair. The plan and ordinance establish a desired end which is
clearly applicable to new development--when streets are built, sidewalks should be installed. As
you know, this is not the case here. The Texas A venue frontage road has been in existence many
years, and development has left the site as the last to be developed in the area. A more equitable
approach to providing a sidewalk that goes no where and won't be used is to construct sidewalks
all along that strip at a later date, with aii owners aiong the frontage being assessed for this
infrastructure at that time. The sidewalk construction on Mr. Kidd's project should be saved for
the future when it will actually go somewhere.
Thank you for your assistance and consideration on this matter. We look forward to a public discussion
of our concerns.
Sincerely, /

RECEf VED ,/ fl 1 g 1994
Ms . Ellison informed the Board that traffic is a major consideration and the proposed expansion will
only increase traffic along Harvey Road including the additional employee parking that will utilize the
alley that currently runs behind the subject property . The final concern is the lack of notification of the
Windwood Subdivision property owners. The requirement is to notify property owners within 200';
however, it is 250' from Furrow's to State Highway 30. The neighborhood was not notified of the
expansion and will be impacted the most by the proposed development. Ms . Ellison requested that the
subdivision be notified in the future of any development in the general area.
Chairman Hawthorne closed the public hearing .
Commissioner Hall moved to recommend denial of a rezoning request of 1 . 77 acres located in the
Harvey Road East Subdivision adjacent and to the rear of the existing Furrow's site from C-1 General
Commercial to C-2 Commercial Industrial. The motion died due to lack of a second .
Commissioner Lightfoot moved to recommend approval of the rezoning request from C-1 General
Commercial to C-2 Commercial Industrial. Commissioner Lane seconded the motion .
Commissioner Lightfoot stated that he sympathizes with the concerns of the Windwood homeowners;
however, there are still many trees on the lot located between Highway 30 and the subject property .
The noise from the traffic along Highway 30 is probably more consistent and constant than the
increased noise caused by the proposed addition .
Assistant City Engineer Morgan stated that drainage is more of a site plan issue than a zoning or
platting issue. The site plan must comply with the current ordinance .
Chairman Hawthorne stated that Furrow's has a considerable problem and the proposed rezoning
should not have much of an effect as far as noise and traffic . He requested that staff look at the traffic
of the overall area to see what can be done to solve the traffic problems around the intersection of
State Highways 6 and 30 .
Commissioner Hall expressed concern that Furrow's is attempting to fix an immediate business
problem by providing additional employee parking . Not all cars parked in the Sam's parking lot are for
employees . The proposed expansion is not a so lution to the problem and would only free up
additional parking for employees and customers . Commissioner Hall stated that he cannot vote in
favor of the rezoning request because Furrow's is not looking at providing a long term solution that
will benefit the entire neighborhood . If a business wants to expand , it should be their responsibility to
take care of the existing problems with the business . This is an opportunity to solve a much larger
problem and Furrow's should come back with a better solution .
The motion to recommend approval of the rezoning request passed ( 6 - 1 ); Commissioner Hall voted
in opposition to the motion .
AGENDA ITEM N O. 5: Considera t ion of a n appea l from the P r oject Review Committee to
require a sidewalk a long the Texas Avenue frontage road for the proposed Goodyear Tire Store
to be located on lot lA, block 15 of the So u thwood P laza P h ase One Subdivision. (94-412)
Assistant City Engineer Morgan informed the Commission that the Project Review Committee
required a sidewalk along the Texas Avenue frontage road in accordance with the sidewalk master
plan . There is an existing concrete cap over the adjacent drainage ditch that would allow for
pedestrian access into the Sonic site .
Greg Taggart with the Municipal Development Group informed the Commission that the owner of the
property has concerns with building a sidewalk that leads to the Sonic Site that does not have a
sidewalk . He agrees that sidewalks have to be installed at some point in time ; however, this is not the
time to install a sidewalk that will not be utilized . Timing is the main concern in that other properties
along Texas Avenue must install sidewalks at the same time in order for them to be utilized . The City
could install a continuous sidewalk at a later tim e and assess each property owner for their section of
the sidewalk .
P & Z Minut es A 11g11st ../, 199-1 Page 5of 7
Commissioner Hall expressed concern with inst alling a rail or fence along the drainage cap so that
pedestrians do not fall into the drainage ditch .
Assistant City Engineer Morgan explained that since that secti on is a drainage right-of-way, the City
will install the rail. The sidewalk the applicant is required to build would stop short of the inlet box .
The City would try to fund the small piece that would take you through the 30' drainage right-of-way .
Commissioner Hall stated that the City should not encourage a sidewalk that leads into an open
drainage inlet unless they are prepared to install a rail and build their portion of the sidewalk .
Commissioner Lane questioned if the applicant cou ld make a donation to a sidewalk fund that could
later be used to construct the sidewalk .
Assistant City Engineer Morgan stated that the City does not currently have that capability . The City
can assess the property owners ; however, there is not a full cost recovery due to administrative costs .
Commissioner Lightfoot agreed with Commissioner Hall and stated that there will probably be some
pedestrian traffic with the adjacent Sonic and Walmart developments .
Commissioner Gribou moved to deny the variance request and require a sidewalk along the Texas
Avenue frontage road for the proposed Goodyear Tire Store to be located on lot 1 A, block 15 of the
Southwood Plaza Phase One Subdivision . Commissioner Smith seconded the motion .
Commissioner Hall moved to amend the original motion to require the City to complete their portion
of the sidewalk near the drainage cap including the handrail with the construction of the sidewalk for
the Goodyear Tire Store. Commissioner Lightfoot seconded the amendment which passed unopposed
(7 -0).
The original motion to deny the variance request as amended passed unopposed (7 -0).
AGENDA ITEM NO. 6: Consideration of a previously tabled Zoning Ordinance
Amendment to Section 12.3B and Table II , pertaining to the regulation of subdivision signs.
(94-803)
Commissioner Hall moved to remove the proposed Zoning Ordinance amendment pertaining to
subdivision signage off the table . Commissioner Gribou seconded the motion which passed
unopposed (7 -0).
Staff Planner Kuenzel informed the Commission that after researching the original Section 12 of the
Zoning Ordinance, nothing specific was found that dealt with the 1 O' setback requirement for
subdivision signs . As the Streetscape regulations a ll ow for planting within the right-of-way and the
sign regulations call for landscaping to be placed around subdivision signs, it makes sense that
someone would want to incorporate the two . The proposed ordinance amendment does not allow
placement within the right-of-way without the City's approval. It merely removes the IO' setback
requirement. The City will not approve a subdi vision sign in any location that would impair visibility
or interfere with utilities. The proposed amendment allows the developer and the City some flexibility
in sign placement.
Commissioner Hall stated that he is sti ll concerned with signage being placed in the right-of-way .
When the sign is placed on private property it is clear who is responsible for maintenance; however, if
signs are allowed in the right-of-way, the maintenance responsibility is not as clear. The subdivision
signs for Woodcreek and Emerald Forest Subdivisions are examples of signs placed in the right-of-
way.
Staff Planner Kuenzel stated that the maintenance is still the responsibility of the homeowner or
possibly a homeowner's association if placed in the right-of-way . Even on a residential lot the
property owner is responsible for maintenance to the curb line and not the right-of-way line .

Re: Goodyear Bldg . in College Sta tion located on
Texas Avenue. Your letter of 9 -2 8 -95.
Dear Ms. Morgan:
I ha ve tried for weeks to find out who sh ould be
responsible for the sidewalk at the new Goodyear
Store not meeting the A. D. A. requirements. I
would like to relate to you my findings.
Let r,1e begin with when I first found out that I would
be building a store for Goodyear in College Station,
I decided to use an Engineering firm in College
Station who had worked with the City and was familiar
with requirements. In conversation with the Seller
of the land that I purchased, I was told that Municipal
Development Group (Gregory Taggart) did a lot of work
for the Ci·ty and this firm would be recommended to do
whatever work that was needed.
To rna~e a long story short, Gregory Taggart with
Municipal Development Group developed a site plan for
the project (which did not include a sidewalk because
he said that one would probably not be required) and
he submitted the drawing (site plan) to your office
and a permit was issued for us to begin the site work
which included the driveway. Driveway and all concrete
work was performed since we had a permit to do so.
What happened next was that a meeting was held which
you (Veronica) and Gre g ory Taggart were in attendance
and it was decided that al l new construction was to
have a sidewalk. This information was re lated to me
by Gerald Prickette, the Bui lde r .
He (Gerald Prickette)were told by your office that we
had to put in a sidewalk. There was never a mention
that the driveway had io be torn up and replaced or
that the sidewalk had to have a sl ope at the driveway
to meet A . D. A. standards.

The bu i ldin g was completed in January and to our
s u rprise a conditional Certificat e o f Occupancy was
issued with the stipulation that the d r iveway apron
b e torn out and replaced to meet A . D. A . stan d ards.
When we received the Cert if ica te, Gerald Pricl<e t te
had a conversati o n with yo u concernin g the circ umstanc e s
t h at I now brin g to your attenti o n and y o u a d ~i t t e d to
hir;l t hat Municipal Developme n t Grou p should be made to
repair the driveway . In y o u r discussion (accordi ng to
Gera l d Prickett e ) you indicated that you wo uld talk
t o Gre g ory Ta gg art about the probleITT and see if they
wo u ld do the repairs . You indicated to hira that
Mu nicipal Development Group performs a n u mber of
services for the City of Coll e g e Station and yo u would
lean on him to do the repairs .
Goo d y e ar Tire and Rubber Comp a ny has e xpr e-ssed to me
that this is the best construction jo b that I have
performed for t h em and I have done s t ores from Conroe
to the Va l ley . They ar e happy with th e driveway as it
appears and if I un d erstand what yo u are requirin g ,
you are as k in g for the sidewalk to be r ais e d appr ox imat e l y
1 1/2 " from the curb to leve l out t he s ide\valk which
according to t h e Contractor , this is g oin g to c a u s e
a situation like a "sp ~ed bump " for Goodyear customers
who in g res s and e g ress f r om the property .
Thi s disruption in business at the Goodyear st o r e i s
n et necessary and has been created b ecause of communicati o ns
betwe e n y o ur office, Municipal Development Group and my
Bu ild er . I have receive d a cost of $5,0 00 .0 0 to d o the
requir e d -work and I f e el that y o u r o ff i ce (because you d i d
app r o v e th e site wo rk plan a n d all o wed us t o do all of
t h e site worok includin g p avi n g) sho u ld share sor.le of the
r e sponsibilit y .
I th e r e fore reque s t tha t a variance be is s ued i n l ieu of
the repairs that yo u are askin g to be made and a
Certi f icate of Occupancy be issued t o Goody e ar without
bein g con d itional .
I a m copyin g your Mayor and all City Councilman and as k
that they g o by the Go odye a r store and observe th e
problem and if they fe el that th e Driv e way n eeds to be

I have reviewed the report submitted for this project, and provide the following comments .
As discussed earlier with your associate, John Conquest, several different projects have been
developed which drain into the detention basin adjacent to this site since the original basin
design report included in your report as an appendix, was prepared . As a result, we believe that
the limited capacity of the basin has been reached, if not already exceeded .
These projects include the First Federal expansion, the Brazos Valley Schools Credit Union Site,
the Albertson's Expansion as well as the Wal mart Expansion, all of which are either approved or
were submitted prior to this application . Therefore we believe that your management of the
storm water runoff must be handled by one of three means .
Your first option is to re-analyze the basin using both existing and currently proposed
development in the area, as well as the existing volume of the basin . Should capacity be
available, this project would be allowed to drain as proposed in your report
Your second option is to analyze the basin including a ll current and proposed upstream
development in order to determine the timing of the outflow of the basin in an attempt to show
that the peak discharge from your small site wo uld in fact be handled by the e?Cisting facilities
prior to the timing if the peak basin discharge. ·
Your third option would be to provide on-site detention per our normal ordinance requirements .
These options were discussed with Mr . Conquest weeks ago during your early planning stages,
and your firm was informed of the existing ba s in situation in writing w hile working on the First
Federal expan s ion drainage repon
Please contact me once you have reviewed this information if you have any questions or wish to
discuss these options in more detail.

The Goodyear Tire & Rubber Company
General Location
The proposed Goodyear Tire & Rubber Company is bounded by Texas Avenue Frontage
Road on the northeast and by Brothers Boulevard on the southeast side . The site is at the
northwestern intersection of Texas Avenue and Brothers Boulevard. The legal description is Lot
lA, block 15 of Southwood Plaza, Phase One.
Property Description
The Goodyear site is a total of0.84 acres . Lot lA is currently unimproved grassland .
The proposed expansion will add 0 .69 acres to the total impervious area.
Construction of this tract as a Goodyear Tire sales and service store is proposed by
0 . A. Kidd ofLondontown Properties. The land is zoned Cl and no change is proposed.
Primary Drainage Basin Description
The tract currently sheetflows at a slope of 1.3 % to 2 .5% to the northeast onto Texas
Avenue Frontage Road which then flows into a ditch between Texas Avenue and the frontage
Road . The ditch flows in a southeastern direction under Brothers Boulevard through a 8' X 4'
box culvert . This culvert travels beneath Texas Avenue and discharges into Bee Creek,
Tributary A.
The tract does not lie in the 100 year floodplain , according to the F .E .M .A. "Flood
Insurance Study for the Brazos County, Texas and Incorporated Areas" on panel 22P .
Drainage Facility Design
There currently exists a detention pond adjoining this property to the west. This pond
services 44 acres upstream including Wal-mart and Albertsons . See Drainage Map contained in
appendix . According to routing calculations, this detention area is not currently at peak storage
capacity and will adequately detain Goodyear's excess runoff for a 100 year storm. The depth of
the detention pond without Goodyear's runoff is 2 . 1 1 ft ., and with Goodyear's runoff is only 2 . 15
ft . The maximum allowable depth is 3 ft . due to the 5' X 3' box culvert passing beneath Texas
Avenue Frontage Road .
A flume will provide runoff for the Goodyear site . See Site/Landscape Plan. Water will
flow across flume and drop over existing concrete wall into detention channel , similar to Sonic's
flumes . The 5' X 3' box culvert serves as a restricting device for the detention pond . Therefore,
water will not be restricted from the Goodyear site into the pond.

PURPOSE
This report has been prepared to present the findings of an investigation of the
impact on the existing detention basin in Block 15 of Southwood Plaza in College
Station, Texas, by the Albertson's Center proposed on Lot 4A in Southwood
Plaza phase two. This detention basin was constructed at the time of
construction of the Walmart Discount Center on Lot 3 in Block 15 of Southwood
Plaza.
LOCATION
This detention basin is located in Block 15 of Southwood Plaza phase one in
College Station, Texas, as described by plat recorded in Volume 1212, Page 483
of the Official Records of Brazos County, Texas. The detention basin is shown
as drainage right-of-way and is located immediately downstream of the storm
sewer running through the Walmart parking lot in Lot 3 of Southwood Plaza. A
drainage map for this project is included at the end of this report showing the
entire drainage area and the travel path for storm water. ·
DRAINAGE AREA
. · The drainage area upstream of this detention basin consist of approximately 44
acres of partially developed land that is zoned general commercial (C-1 ). It is
bounded generally by Hilltop Drive, Airline Drive, F.M. 2818 and Brothers
Boulevard. The existing land uses are a U.S. Post Office, an auto repair shop
and service station, a branch bank, a neighborhood convenience store and a
Walmart discount store. Approximately 18.4 acres is presently undeveloped, but
12.2 acres of that is the proposed Albertson's Center.
HYDROLOGICAL CONSIDERATIONS
The rational formula for calculating stormwater runoff will be used since the area
is less than 50 acres.
Table 11-1 on page 23 of the Drainage Policy and Design Standards fo'r the City
of College Station, recommends a runoff coefficient of between 0.35 and 0.45 for
natural grasslands that slope between 1 % and 3.5% and a runoff coefficient of
· between 0.65 and 0.75 for Business/Commercial land uses. The land slope in
,. this drainage basin is within the 1 % to 3.5% range .
When the Albertson's Center is completed, the drainage basin will have 37.8
acres of Business/Commercial and 6.2 acres of undeveloped natural grassland.
Assuming a rurioff coefficient of 0.7 for Business/Commercial and a runoff
coefficient o.f 0.4 for undeveloped natural grassland, the following calculations
show that a Wf?ighted runoff coefficient of 0.66 can be used for the total drainage .

To determine the Time of Concentration, the method described in Technical
Release 55 URBAN HYDROLOGY FOR SMALL WATERSHEDS by the United
States Department of Agriculture Soil Conservation Service dated Jun~ 1986
was used. EXHIBIT - 1 on the following page describing sheet flow, Figure 3-1
for determining velocity for shallow concentrated flow and Worksheet 3 for .
determining Time of concentration have been reproduced from this publicatiqn.
The flow path indicated on the ·drainage area map shows that the most
. hydraulically remote point is near the north corner of the Post Office tract near
the frontage drive on FM 2818. From this point there will be sheet flow for
approximately 17 4' and then becomes shallow concentrated flow until entering
the culvert under Longmire Drive. From Longmire Drive through the proposed
Albertson's Center to the Walmart tract, flow will be through 42" RCP and
through the Walmart tract, flow will be through 48" RCP. Manning's equation for
open channel flow was used to determine the velocities through the storm
sewers assuming full flow. ·
V = 1.486r213s 1/2
n
For a 42" RCP with n = 0.014, V = 8.41 fps and for a 48" RCP with n = 0.014, V
= 7.51 fps.
The length of travel for the 42" RCP is 590 feet and the length through the 48"
RCP is 600 feet. When these factors are entered into Worksheet 3, the resulting
time of concentration is approximately 33 minutes .

EXHIBIT 1 -Time or Concentration
Sheet Flow
Sheet flow is flow over plane surfaces. It
usually occurs in the headwater of streams.
With sheet flow, the friction value (Manning's
n) is an effective roughness coefficient that
includes the effect of raindrop impact; drag over
the plane surface; obstacles such as litter, crop
ridges, and rocks; and erosion and transportation
of sediment These n values are for very
shallow flow depths of about 0.1 foot or so.
Table 3-1 gives Manning's n values for sheet
flow for various surface conditions.
For sheet flow of less than 300 feet, use
Manning's kinematic solution (Overton and
Meadows 1976) to compute Tt:

where
T t = travel time (hr),
n = Manning's roughness coefficient {table 3-
1),
L = flow length (ft),
P2 = 2-year, 24-hour rainfall (in), and
s = slope of hydraulic grade line (land slope,
ft/ft).
This simplified form of the Manning's
kinematic solution is based on the following: (1)
shallow steady uniform flow, (2) constant
intensity of rainfall excess (that part of a rain
available for runoff), (3) rainfall duration of 24
hours, and (4) minor effect of infiltratio_n on
travel time. Rainfall depth can be obtained
from appendix B.
Shallow concentrated flow
After a maximum of 300 feet, sheet flow
usually becomes shallow concentrated flow.
The average velocity for this flow can be
determined from figure 3-1, in which average
velocity is a function of watercourse slope and
type of channel. For slopes less than 0.005 ft/ft,
use equations given in appendix F for figure 3-
1. Tillage can affect the direction of shallow_
concentrated flow. Flow may not always be
directly down the watershed slope if tillage runs
across the slope.
After determining average velocity in figure 3-
1, use equation 3-1 to estimate travel time for
the shallow concentrated flow segment
Open channels
Open channels are assumed to begin where
surveyed cross section information has been
obtained, where channels are visible on aerial
photographs, or where blue lines (indicating
streams) appear on United States Geological
Survey (USGS) quadrangle sheets. Manning's
equation or water surface profile information
can be used to estimate average flow velocity.
Average flow velocity is usually determfraed for
bank-full elevation.

Table 1
Approximately 7 acres of highway right-of-way contributes stormwater runoff to
the drainage ditch immediately downstream of the detention basin outlet.
Another approximately 8 acres is upstream of the intersection of Brothers
Boulevard and Texas Avenue. Table 1 above is a tabulation of the runoff
quantities for the various areas for different storms.
HYDRAULIC CONSIDERATIONS
As presently constructed, the detention basin discharges through a rectangular
reinforced concrete channel under the Texas Avenue frontage drive. The
channel has a 5'. bottom width and is 3' deep below the frontage drive. The
channel slope under the frontage drive is approximately 1.75%. Manning's
equation for open channel flow gives a a of 259 cfs with a velocity of 17;3 fps.
At this depth, the volume of detention is approximately 44,000 cubic feet or
about 1 acre foot. With a depth of flow of 2.75', the outlet Q = 180 cfs, V=13 fps
and the volume .of detention is approximately 39,000 cubic feet or 0.89 acre feet.

Discharge from the detention basin Is into a drainage ditch between the frontage
drive and the main lanes of Texas Avenue. Downstream of the detention basin
outlet, the flow is through an 8' X 4' box culvert under Brothers Boulevard. The
difference in elevation from the top of pavement over this box culvert to the
flowline is 4.66 feet. The pavement rises 1.0 foot from the top of the box culvert
to the centerline of Texas Avenue approximately 80' away and slopes up at
2.22% (45:1) back along Brothers Boulevard to the southwest.
The maximum flow through the 8' X 4' box culvert before flowing over the
Brothers Boulevard pavement is approximately 200 cfs which is shown on the
following tabulation of a Box Culvert Analysis Computer Program by Dodson &
Associates, Inc. This agrees with the highway department calculations shown
on the plans for the widening of Loop 507 (Texas Avenue) dated December 18,
1984.

If stormwater is allowed to flow over the Brothers Boulevard Pavement, the
drainage ditch will provide additional detention volume. Assuming the pavement
· section over Brothers Boulevard to be a trapezoidal channel with a 45:1 side
slope right and an 80:1 side slope left, a Manning's n value of 0.018 and a
bottom slope equal to the box culvert of 0.25%, the following tabulation show the
quantity that will pass at various depths over the pavement.

Assuming the present stage of development upstream of this detention basin
plus the development of the Albertson's Center, a 100 year storm would produce
196 cfs of stormwater discharging into the detention basin from the Walmart
stromsewer. Adding to this approximately 19 cfs from the highway right-of-way
upstream of the outlet and another 22 cfs from the 8 acres downstream of the
outlet gives a total of 237 cfs at the culvert under Brothers Boulevard. Assuming
a 2.75' depth of flow at the detention basin outlet, there will be a discharge of
approximately 180 cfs. This discharge plus the 41 cfs from the two down$tream
areas will produce 221 cfs at Brothers Boulevard which would overflow the street
approximately 6" deep. Results of a computer model of this condition is shown
on the following page.

The required · storage volume of 0.66 acre feet is less than the available 0.89
acre feet at the 2. 75' depth.
Assuming full development of the drainage basin upstream of the culvert at
Brothers Boulevard and a time of concentration of 15 minutes, a 100 year storm
will produce approximately 300 cfs entering the detention basin from the
Walmart stormsewer, 55 cfs from the 8 acres discharging downstream of the
outlet and 27 cfs froin the 7 acres of right-of-way upstream of the outlet. If the
9
.:·'
outlet channel flows 3' deep, there will be a discharge of approximately 259 cfs
from the detention pond. This produces a quantity of 341 cfs at the Brothers
Boulevard culvert and will overflow the pavement between 0.9' and 1.0' which
will not overflow Texas Avenue. Computer output of a model for this situation is
produced below.

CONCLUSION
Results of this study show that the present detention basin in Block 15 of
Southwood Plaza is more than adequate to contain the excess stormwater from
a 100 year storm after construction of the Albertson's Center with all other parts
of the drainage basin at present conditions. When all parts of the drainage area
are developed, the present detention basin will still detain enough stormwater to
prevent the overflow of Texas Avenue. This should be adequate during a 100
year storm, since adjoining structures are well above this elevation. The real ·
estate office downstream of Brothers Boulevard has a floor elevation of 3' above
the centerline of Texas Avenue at Brothers Boulevard and the Sonic Drive -Inn
has a patio slab elevation 3.5' above the top of pavement at the detention basin
outlet.

do this v.hile he is already there will save approximately doublbe.
(SEE A'ITACHED MEMJ)
2. Why was the item not budgeted in the normal budgetary process?
Did not know at ti,rne of budget process that this would be done.
3. Justification as to why the transfer can not be made within the division or department?
This is a capital project and it should be taken from contingency rather than
operating budget.

Re: Goodyear Tire Store Sidewalk-TexDOT Comments
Veronica:
As we discussed on Friday, in reference to the comments from TexDOT, we submit the following
reply . This letter is to be considered as an addendum to our original submission. We have
numbered our responses in the order we received them from TexDOT:
1. Need Plans:
-Sidewalk cross-section is provided on the site plan .
-The location is shown on site plan. The sidewalk is drawn to be 6' wide concrete
and is placed against the back of curb .
2 . The width question has been answered -width is proposed as 61 wide.
3 . All ADA standards will be met, and ramps will be 1: 12 slope (as shown on plan), with cross
slopes a maximum of 1/4"/l'. Ramps will be placed at driveway and at Brothers.
4. Sidewalk will be placed with an expansion joint every 40 feet.
5 . Sidewalk will be built according to city specifications which require that sections are
separated by premolded or board joints.
6 . Per city specifications, expansion joint material will be placed against back of curb and where
obstructions are located in the sidewalk.
000004-c.07-08 (2491)

7 . Sidewalks will be marked every 5' in length with a jointing tool (per C .O .C.S. standards).
8 . Reinforcement steel shall be 3/8" diameter bar on 12" centers (per C .O .C.S. standards), as
depicted on the plan details.
9 . Subgrade will be 2" sand cushion on excavated natural ground, as depicted on the site plan .
10. A traffic control plan will not be necessary. The contractor has agreed to keep all work on
the Goodyear site -no work will be performed on S.H. 6 Frontage Road driving surface,
as we discussed . Please see the attached letter from the contractor.
Please feel free to call if you have other questions of concerns.

TO WHOM IT MAY CONCERN:
Please be advised that all work required, i.e., site work, forming, and the
actual placement of the concrete in the construction of the approximately
180 feet of new sidewalk along Texas Ave. will be done from the property side
only with no work being done from Texas Ave., which would interfere with the
traffic flow along the roadway.
If there are any questions concerning our construction plans/procedure, please
let me know.

Dear Pat :
( 409) 764· 3500
Enclosed please find a response to TXDOT's questions on the sidewalk plans for the Goodyear
Tire Store lo cated at 2998 Texas Avenue. These respo nses are from Municipal Development
Group, the civil consultants on the project. I believe they have answered all the concerns that
TXDOT has on the project. Please note that th e contractor has agreed to keep all construction on
the Goodyear site and therefore has not submitted a traffic control plan . The stop sign at the
intersection of Brothers and the fronta ge road w ill be r e located behind the sidewalk, placing it
approximately 7'-8' behind the curb, well w ithin the gui delines outlined in the MUTCD . If you
have any question s, please do not hesit ate to call me . Thanks for yo ur help in expediting thi s

Re: Go odyear Site Sidewalk
Ms. Morgan:
At your request, we have developed the following construction cost estimate for the installation
of the sidewalk and handrail at this site:
l. 6' Concrete Sidewalk 16 LF x $13.50/LF = $216.50
2. Pedestri an Handrail (City Specification) 1 EA x $900 = $900.00
TexDOT has informed us that if they are the controlling agency for this project, they will require
complete construction plans for the sidewalk and handrail, as well as a traffic control plan and
completed construction permit. Fees for services to produce these items will be determined at a
future date.
We look forward to working with you on this project.

safety, the height to the bottom of such signs may be 5 feet above the
level of the pavement edge.
For all roadways, Educational plaques erected below Regulatory and Warn-
ing Symbol signs are not to be considered in the minimum clearances
specified in the above paragraphs.
A route marking assembly consisting of a route marker with an aux-
iliary plate (sec. 2D-10) is treated as a single sign for the purposes of this
section.
Overhead signs shall initially provide a vertical clearance of not less
than 1 7'6" over the entire width of the pavement and shoulders except
where a lesser vertical clearance is used for the design of other struc-
tures. Roadway resurfacing or other factors may reduce the vertical
clearance of overhead signs by raising the level of the roadway. When
such factors have reduced the vertical clearance to 1 6 '6" or less, con -
sideration should be given to re -establishing the 1 7 '6" vertical clearance.
The vertical clearance to overhead sign structures or supports need not
be greater than 1 foot in excess of the minimum design clearance of
other· structures. In special cases it may be necessary to reduce the
clearance still further because of substandard dimensions in tunnels and
other major structures such as double-deck bridges.
2A-24 Lat.era! Clearance
Signs should have the maximum practical lateral clearance from the edge
of the traveled way for the safety of motorists who may leave the road-
way and strike the sign supports. Advantage should be taken of existing
guardrail, overcrossing structures and other conditions to minimize the ex·
posure of sign supports to traffic. Otherwise, breakway or yielding su~
ports should be used.
Normally, signs should not be closer than 6 feet from the edge of the
shoulder, or if none, 12 feet from the edge of the traveled way. In urban
areas a lesser clearance may be used where necessary. Although 2 feet is
recommended as a working urban minimum, clearance of 1 foot from the
curb face is permissible where sidewalk width is limited or where existing
poles are close to the curb.
The minimum clearance outside the usable roadway shoulder for ex-
pressway signs mounted at the roadside or for overhead sign supports,
either to the right or left side of the roadway, shall be 6 feet. This
minimum clearance of 6 feet shall also apply outside of an unmountable
curb. Where practicable, a sign should not be less than 10 feet from the
edge of the nearest traffic lane. Large guide signs especially should be far-
ther removed, preferably 30 feet or more from the nearest traffic lane.
Lesser clearance, but not generally less than 6 feet, may be used on con-
necting roadways or ramps at interchanges.

Complaint Re: Goodyear -Reply
Tom: I looked up the file after I got a copy of Mr. Kidd's letter. As it
turns out, he's partly right -MDG DID turn in a site plan for consideration
that did not show a sidewalk. The PRC voted to require a sidewalk, and the
PRC report (which was sent to Mr . Kidd) stated ... "A sidewalk is required
along thee Texas Avenue frontage road as per the Sidewalk Master Plan. The
sidewalk should begin at the Texas Avenue and Brothers intersection with a
ramp meeting ADA requirements and end at the property line near the existing
drainage ditch. If a variance is requested, submit a formal request by noon
on Thursday •••• ".
A variance was requested, taken to P&Z on 8/4/94 where it was denied, but with
the condition to "require the City to complete their portion of the sidewalk
near the drainage cap including the handrail wi th the construction of th3e
sidewalk for the Goodyear Tire Store." (The condition has been taken care
of.)
A brief synopsis of the dates are: 7/13/94 to PRC
variance
Development Permit
issued
8/4/94 to P&Z for
8/9/94 Drainage
8/15/94 Plans
approved for permitting except area of driveway and sidewalk on Texas Avenue
which was pending TxDOT approval
9/13/94 Revised site
plan to address drainage approved by VMorgan
Veronica is replying to Mr. Kidd's letter as we speak. I will make sure you
get a copy when it is complete.
>>> Tom Brymer 10/09/95 09:35am >>>
This in reference to a letter from 0. A. Kidd of London Town Properties of
Conroe who apparently built the Good year Store on Texas near the Walmart.
He's addressed this Veronica, but copied a bunch of folks including each
Council member. Could you please look into this ASAP for me? If you need a
copy of the letter, I have one and so does Jim c.

RE: GOODYEAR CERTIFICATE OF OCCUPANCY
Dear Sirs :
May 15, 1996
Attached please find a copy of the certificate of occupancy for the Goodyear Store in
College Station. We have removed the condition regarding the sidewalk/driveway
approach and accept your offer to correct the problem at any point in the future if it is
cited as an accessibility compliance problem.
It is my understanding from the Texas Department of Licensing and Regulation that their
variance process cannot be used for this sidewalk problem. According to Ms. Brady, the
variance must be applied for prior to the expected completion date. They did tell me that
if any complaints are registered regarding this problem, that the property owner would be
contacted to immediately remedy the situation. I understand that you are willing to
correct the problem at any time, if contacted by this agency or any other that assures
physically challenged individuals accessibility .
If you have any other questions, please do not hesitate to call.

Re: Lot lA, Block 15, Southwood Plaza
Certificate of Occupancy Permit #9402671
Dear Veronic:
·...J !v ._··J
I sent an application for variance on the sidewal k
situation to the Texas Department of Licensing and
Regulation a nd receive d an answer today by phone
and I quot e :
(1) "The sidewalk is not an acc e ssibility
route to the building and therefore
is not an enforceable issue.
I asked her for this in writing and she said the y
did not give written notices when not an enforceable
issue.
If the abov e answer doe s not satisfy y our requir eme nt s
so that we c an get a Certificate of Oc cupancy, pl eas~
use this l e tt e r as my c e rtification to you that in the
event any Government Agency who repr e sents the ADA As t
comes forward and states the sidewalk is to be torn
out and replaced, I will pay for such costs.
As for as the Certificate of Occupancy is conc erned,
I ~eed a new one without exceptions.
Please call me if you have any questions.
Very truly yours,

EXHI3IT "A"
Wh en we applied for a per ~d t to build the Goo dyear Tire
and Rubber Compan y builiing i n College Sta ti o n, the City
Coun c il was takin g up s~bject of requir ing sidewalks on
all new construction. We received our per mit and
sometime in the middle o f the construc ti on period we
were told that we would have to put in th e sidewalks.
We had completed 0ur ingress and egress at that time to
the premises and in laying the sidewalk on City property,
because the sidewalk abutted the curb, this did not allow
the slope at a 2% level, therefore the sidewalk crossing
the driveway was at a slope.
To achiev~ compliance and allowing the d r iveway slope to
be at the 2% level, we would have to tea r out the driveway,
levelinR the sidewalk, and in effect would cause an
abrupt speed bump effect" wh i ch could p oss ibly lead to
damage to some of Goodyea r 's customers ingr e ssing and
egressing the property.
The Tenant, Goodyear Tir e and Rubber Comp a ny has requested
that a change not be ma<le for fear of damaging Customer's
vehicles.
To achieve compliance at the 2% level would cost $5,000.00.

RE: GOOD YEAR CERTIFICATE OF OCCUPANCY
Dear Mr. Kidd :
The previous letter that I sent today is somewhat confusing. I did not intend to address
the comments within the letter to Mr. Bien, but rather inform him of the status of the
project . Where I stated that it is my understanding that you are willing to correct the
problem in the future if contacted, was meant to be a paraphrase of the similar sentence in
your letter . I did not intend the "you" in that sentence to mean Mr. Bien.
I hope this has clarified the previ ous letter. If you have any questions , please do not
hesitate to call.
