out movement of the truck exit is required, the Developer shall be responsible for the cost and <br /> construction of the acceleration lane. Should a problem develop in the future as a result of <br /> operational changes, HEB will work with TxDOT to construct appropriate solutions. The City will <br /> not be responsible to fund any improvements. <br /> The Developer expects an average of eight delivery trucks (18-wheeler) a day at the site and 18- <br /> wheeler deliveries to the store shall be prohibited between 7:00 a.m. — 9:00 a.m. (Monday — <br /> Friday), 11:00 a.m. — 1:00 p.m. (Monday— Friday), and 4:00 p.m. — 7:00 p.m. (Monday— Friday). <br /> Further, 18-wheel delivery trucks exiting the property shall be prohibited from making any U-turns <br /> along Wonder World Drive until such time as Developer elects to construct a truck turnaround <br /> along Wonder World Drive. Preliminary plans for the truck turnaround are shown in Exhibit G and <br /> final design shall be subject to TxDOT approval. A sign prohibiting 18-wheeler U-turns shall be <br /> installed in accordance with approved City specifications at the intersection of Wonder World <br /> Drive and Craddock Avenue. The Developer shall pay for the signage, until such time as Developer <br /> has secured TxDOT approval and elects to construct a truck turnaround. <br /> d. Floodplain: <br /> No grading is proposed within the FEMA effective 100-year floodplain except for the limited grading <br /> associated with the bike path and the northern driveway on Hunter Road. Current modeling shows that <br /> the "Storm of Record" flood line slightly encroaches onto the northeast corner of the proposed site. <br /> See "Exhibit C". The proposed grading for the site will be designed to follow existing grades as closely <br /> as possible, thereby minimizing impact and preventing the 100-year water surface elevation within <br /> Purgatory Creek from increasing downstream of the site. A 2D model based on the storm of record has <br /> been provided to the City by the Developer to verify compliance with the above. <br /> e. Detention: <br /> The property discharges to Purgatory Creek on the north side of the property. Purgatory Creek has a <br /> drainage area of 35 sq. mi. at the project site, and is regulated by two large Natural Resources <br /> Conservation Service (NRCS) Dams. The lower of the two dams (NRCS Dam No. 5) is located only <br /> mile upstream of the site. Detention will be provided as required at the time of site development <br /> permitting once a final site plan and grading are established. A drainage study, including a revised 2D <br /> model, will be provided at this time demonstrating that the final site plan will not increase the water <br /> surface elevation 1,000 feet downstream of the site. In addition, the required onsite water quality <br /> facilities will provide an element of detention so that there is no increase in flow downstream of the <br /> site for the 2-, 10-, 25-, and 100-year storm events and the "Storm of Record" (defined as 10.87 inches <br /> of rainfall in a 24-hour period with a resulting flow depth over the emergency spillway of 5.99 feet as <br /> experienced in 1998) (see Section 4.g). <br /> f. Impervious Cover: <br /> The proposed development will meet the Base Regulation requirement for 80% maximum impervious <br /> cover for General Commercial zoning. In addition, the development will not exceed a maximum of 35% <br /> impervious cover on hillsides with slopes from 15%to 25% and a maximum of 20% impervious cover on <br /> hillsides in excess of 25%. <br /> Doan 12 <br />
