HomeMy WebLinkAbout16 Development Permit 243 GoodyearDrainage Report For The Goodyear Tire & Rubber Company College Station, Brazos County, Texas Prepared For: 0 . A. Kidd Prepared By: Municipal Development Group 203 Holleman Drive East . College Station, Tx 77840 (409) 693-5359 Approved By: North Bardell, P .E . 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. 2818 SITE LOCATION ~LANE VICINllYMAP NOTTO SCALE GoodYear Tire Store Drainage Area Area 46 .86 C factor 0.78 · Present Time of Concentration 30 Future Time of Concentration 10 Area around Pond 2.66 0.60 10 10 DRAINAGE AREA • GoodYear Tire Store Rational Method (Q = CIA) Pre-Development Area Description (acres) Q Grassland 0.84 0.35 Post-Development Area Description (acres) Q C(area} landscaping 0.15 0.35 0.053 Impervious Area Q.69 0.90 0.621 0.84 0.674 Cavg = 0.674 I 0.84 = 0.80 Runoff Req'd Storage Frequency Intensity• Cpre Cpost Qpre Qpost Vpre Vpost Volume ~ Cin/inl ---(cfs) Ccfs) {Qfl {Qfl {Qfl 100 12.6 0.35 0.80 3.70 8.49 3334 7637 4304 50 11.1 0.35 0.80 3.26 7.48 2937 6728 3791 25 9.9 0.35 0.80 2.91 6.67 2620 6001 3381 10 8.3 0.35 0.80 2.44 5.59 2196 5031 2835 5 7.7 0.35 0.80 2.26 5.19 2037 4667 2630 *NOTE: Tc= 10 min 100 Year Hydrograph for GoodYear Tire Store 10 -r--~~~~~~~~~~~~ 8 --------------------------------------------------------------------------------------------------------···--··-----···-·-----·-·----·····--····-·--·-·---·-··-·····--··---------·-·--····--------·-·----·-·····-·-··-·····--·-···-··-·------·---··--·-·····--·------ a 4 2 ---···-··········· ---·-······----------··--------------·---·--·---------------------·-·---·-··-------·--··-·--····-·-·-·-·-···············-···--····-······ ·-·-·-·-·········-------·-·-·······----------·····-··-----···-··-···········--·------- 0 ----+---+--+--+--+--+--+---+--+---+---+~ 0 5 10 15 20 25 Time (min) ---Qpre ---Qpost 30 Immediate Area around Detention Pond Rational Method (Q =CIA) Pre-Development Descrjption Pre-Sonic Pre-GoodYear Grassland Post-Development Qescrjption Sonic GoodYear Future Development Cavg :c: Runoff Frequency (years) 100 50 25 10 5 Area (acres) 0 .81 0.84 111 2 .86 Area ~ 0.81 0.84 w 2 .860 2 .288 Intensity* (in/in) 12.6 11 .1 9.9 8 .6 7 .7 I Q 0 .35 0.35 0 .35 .Q 0.80 0 .80 0.80 2 .86 Cpre 0 .35 0.35 0 .35 0 .35 0.35 = CC area) 0 .648 0 .672 0 .968 2 .288 0.80 Cpost 0.80 0.80 0 .80 0.80 0.80 "NOT!: Tc= 10 min Qpre (cfs) 5.34 4.70 4.19 3 .64 3 .26 Req'd Storage Qpost Vpre Vpost Volume (cfs) {£f} {£f} {£f} 12.20 4802 10977 6175 10.74 4231 9670 5440 9 .58 3773 8625 4851 8 .32 3278 7492 4214 7 .45 2935 6708 3773 100 Year Hydrograph for Area Adjoining Detention Pond 14 12 10 .....-... ~ 0 8 ........... 6 a 4 2 0 0 5 10 15 20 25 30 Time (min) ---Qpre ---Qpost 100 Year Hydrograph for Present Drainage Basin 350 300 250 ~ $? 200 0 '-" 150 0 100 50 0 0 20 40 60 80 100 Time (min) -11-Qpre -11-Qpost Drainage Area for Detention Pond Rational Method (Q = CIA) Pre-Development Descrlption Grassland Post-Development Runoff Description WalMart Albertson's Weinerschnitzel Circle K Auto Center Credit Union Motor Bank Post Office Residential Future Development Future Development Future Development Undeveloped Streets Detention Pond Cavg = Frequency (years) 100 50 25 10 5 Area (acres) 46.86 Area (acres) 13.67 7.73 1.12 1.01 1.21 2.22 2.31 6.51 2.60 1.42 1.04 0.88 1.35 3.10 0.69 46.860 36.352 Intensity* (in/in) 12.6 11.1 9.9 8.3 7.7 ~ 0.35 ~ 0.86 0.86 0.80 0.80 0.80 0.72 0.70 0.70 0.60 0.70 0.70 0.70 0.40 0.90 0.40 I 46.86 = Cpre -0.35 0.35 0.35 0.35 0.35 C(area) 11.756 6.648 0.896 0.808 0.968 1.598 1.617 4.557 1.560 0.994 0.728 0.616 0.540 2.790 0.276 36.352 0.78 Cpost 0.78 0.78 0.78 0.78 0.78 "NOT!!: Tc., 10 min Qpre (cfs) 206.65 182.05 162.37 136.13 126.29 (With development d Block 2, Lois 2A & 4R-A) Req'd Storage Qpost Vpre Vpost Volume (cfs) .(Qfi .(Qfi .(Qfi 458.04 185987 412236 226249 403.51 163846 363160 199314 359.89 146133 323900 177767 301.72 122515 271552 149037 279.91 113659 251922 138263 100 Year Hydrograph for Drainage Basin in Future 500 --r--~~~~~~~~~~~--, 400 ~300 0 ............. a 2 o o ·-·······--·······-····-·-·····-· ····-·-·-·····-·····--····-·-··-······· . ····-·-----····-···············-····-·-··-·····-·-·-·-·-········-····--·-·-·-···-··· ·-·--·-·-············-·--·················-····-·-·-···-····-·-·--· 100 o ~~-+--+---4--4--+--+--+--+--t---+~ 0 5 10 15 20 25 30 Time (min) ---Qpre ---Qpost l'loullng for CWolntlon Pond wit'-'!

Joe Orr, Inc. S_,ar1 & &1iMu1 2167 Post 03 Circle College Station, Texas 77845 ·. (409) 690-3378 .. 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 . basin. · . ..... . · .. · . .-.: ~ ...... ._, __ _,......._ .. .

EXHmrr 1-Time or Concentration 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: T -0.007(nL)o.I t-(PJrut'-4 [Eq. 3-3] Table 3-1.-Roughness coefficients (Manning's n) for sheet now · Surface description n 1 Smooth swfaccs (conacte, asphalt, gravel, or bare soil) .. -··-······-··········-·········-····· 0.011 Fallow (no rcsiduc) ... -........ -··-···--······-·· O.OS Cultivated soils: Residue cover S209:..-.......... _ •• _............. 0.06 Residue covcr>209:.._ .. _: .... -...... -......... 0.17 Grass: Short grass prairie .•.••• -.......... -...............

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.

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.

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.

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.

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. 11 DEVELOP~1EN T S ERVICES ffOl TE X AS AVE CO LLEGE STAT IO N, TEXAS 77840 Fac si mile C over S heet T o: Company: Phone: Fax: From: Company: Phone : Fax: Date: Pag es including this cover page: ~~ I ~~ S[,61ttv k (409) 7 64-35 70 C409) 76 4 -34 96 FAX /0t~~:rnt ~m:MtMmi tiii ilihL~., ,~ "1·1 ·1 ·1 ·! ·1 ·1•/· i·l·l ·l·/•l•/ •/•l •/•.'·l •l ·l ·l·.'•I · .,.,., .. ,.,.,.,.,.,., .. ,.,.,., .. ,.,.,.,.,.,.,.,., .. ,., ..... , ·l·l ·l ·l·l·l ·l·l·l •l ·l · l·l ·/·l ·l ·l ·l ·l ·l·/ ·!·l ·J l·l ·l •\. \• \. \. \• \ •\• \ •\.

Box 9960 Colle ge Station, Texas 77842-9 960 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.

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.

Box9960 College Station, Texas 77842 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.

PRC Report Goodyear Tire Case #94-412 Page 2 of 3 The following are ordinance requirements and comments outlined by the various staff: ORDINANCE REQUIREMENTS: Site Plan Related: Show paving and sidewalk details on the site plan or construction documents. Show the proposed water meter which must be included in an easement. Staff suggested that the meter be located directly off the main so that an additional easement is not necessary. The site must comply with the current drainage ordinance. The site plan submitted is based on no detention requirements which the applicant must prove. If detention is required, the site plan must be reconsidered by the Project Review Committee. Other Ordinance Requirements: A highway department (TxDOT) permit is required prior to construction of the driveway along the Texas Avenue frontage road. The City will coordinate this process. STAFF COMMENTS: The proposed sign must be permitted separately. Underground electrical service will be required. Complete and submit the enclosed electrical service request form and the temporary blanket easement information sheet for construction purposes. Once the project is complete, the necessary easements can be dedicated by an easement dedication plat or by separate instrument. The developer is responsible for 20 % of the cost of electrical service. The developer also installs conduit from the transformer to riser pole locations designated by the City, per City specifications and requirements. The developer is also responsible for the installation of the transformer pad per City design and specifications. Provide the main disconnect size, electrical load data and voltage requirements. A meter will be located on the building with CT's mount inside lockable CT can be provided by the developer. CT's and meter socket furnished by the City and installed by the developer. Service conduit must be installed by the developer per City specifications. The City will furnish and install the service conductor including the CT's and meter socket. Once the transformer location and route of service is decided by the developer and City, the City will prepare the electrical layout and provide a copy of that layout for the developer to use for the installation of conduit and pads. / PRC Report Goodyear Tire Case #94-412 Page 3of3 If there are any conflicts with existing power pole locations, the poles will be relocated at the cost of the developer. The pole will be removed when underground installation is complete. A road bore will be necessary to install two 4" conduit under Brothers to serve the property. Also, two 4" conduit will need to be installed to the riser pole and transformer location. Place one 3" PVC pipe with pull string from the Texas Avenue right-of-way to the outside termination (DMARC). The conduit should ell up 4' at the building termination within 20' of power. Provide requirements and occupancy date. Send copy of site plan indicating GTE conduit placement and coordinate service details with GTE Representative Laverne Akin at (409) 821-4723. SUBMIT 4 COMPLETE SETS OF CONSTRUCTION DOCUMENTS WITH THE REVISED SITE AND LANDSCAPE PLAN A TT ACHED AND 4 ADDITIONAL COPIES OF THE REVISED SITE AND LANDSCAPE PLAN ONLY TO CONTINUE WITH PHASE II OF THE BUILDING PERMIT PROCESS.

Box 9960 College Station, Texas 77842 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, / ~ /(. /;yyo&J '}.rega._r/K Tlsart // Vice Preside t /kim 000004-c .05-06 (2491) 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 .

Bo x 9960 Colle ge Station, Texas 77 842 -9 960 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. ~hnn ~nfutt Jrnperties ~tal ~1brlt !Jeuelop en 4 14nui .sia na J ar k J. ®. illnx !S83 Clrnnrnc . wu:a.s m os Wdcµltnnc (4 09) 760-4 000 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 .

BOX 9960 11 01 TE X AS AVEl'!<IE COL L EGE STATI ON . TEXAS 7784 2 -0960 (409) 764 -3500 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.

A. Kidd Prepared By : Municipal Development Group 203 Holleman Drive East College Station, Tx 77840 (409) 693-5359 June , 1994 Approved By : North Bardell , P .E . 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. !AINAGE AREA -GoodYear Tire Store Rational Method (Q = CIA) Pre-Development Area Description (acres) ~ ~{area) Grassland

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 . basin. · ·' ··,· · .. ·~ ·. =9",.!--........ ,-.-~·· . ~· -.J. • .• .: ....... ., .

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 . 2 . - 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: [Eq. 3-3] Table 3-1.-RoughneM coefficients (Manning's n) for sheet flow · Surface description n1 Smooth surfaces (concrete, asphalt, gravel, or bare soil)............................................... 0.011 Fallow (no residue).................................... 0.05 Cultivated soils: Residue cover S20% ................. -............. 0.06 Residue cover >20% ...... :......................... 0.17 Grass: Short grass prairie .................................. .

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. · · (210-VI-TR-55, Second Ed., June 1986) ··-· 3 .... ..... ........ .... ..... .. Q) a. 0 en Q) en ... :::> 0 0 ...

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. 6 > lf' ; ,, M ~i· ' 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.

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.

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.

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.

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. 11 DEVELOPMENT PERMIT PERMIT NO. 242 FOR AREAS OUTSIDE THE SPECIAL FLOOD HAZARD AREA RE: CHAPTER 13 OF THE COLLEGE STATION CITY CODE SITE LEGAL DESCRIPTION: Lot JA, Block 15 , Southw ood Plaza , Phase 1 SITE ADDRESS: 2998 Texas Avenue between Brothers and Sonic OWNER: O.A.

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) Veronica Morgan Page 2 October 25, 1994 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.

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. TX 2A-14 (Rev. No. 4) ¥ .. ~ Gerald S. rickette Consultin ngineers, Inc. 1001 S.

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. CC: eash, jcallaway, vmorgan, klaza . ., ·~ . ,., . \• •.·\. , .. ,. ,.

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 .

APPLICATIONS RECEIVED A YMEl'ff WILL NOT BE PROCESSED. , 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.

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.
