Assistant City Engineer City of College Station Post Office Box 9960 College Station, Texas 77842 Re: Sonoma Subdivision, Phase 3 — Oversize Participation Request Dear Josh: xc: Mr. Randy French, BCS Development Co. On behalf of the owner, BCS Development Co., I wish to request Oversize Participation by the City of College Station for costs associated with the development of Sonoma Subdivision, Phase 3. The City's Master Utility Plan shows a 24" water line to be extended along the east side of William D. Fitch Parkway. This letter is to request oversize participation from the City for the cost difference between the 24" water Tine and an 8" water line which would normally be required for this development. Accompanying this letter are two exhibits. Exhibit A is a copy of the output file from a KYPIPE computer model of the Sonoma Subdivision including an 8" water line (Pipe No. 19) along William D. Fitch Parkway to serve Lot 1, Block 9. This model shows that the lowest pressure in the system with the 8" is 64 psi under fire flow conditions (hydrant located © Lot 1, Block 9). This exceeds the minimum pressure of 20 psi required by TCEQ. This proves that the system performs adequately with the 8" line. Exhibit B is a series of estimates that shows the cost differential between the 24" and the 8" water line. That difference is $147,614.50. This number is value of the oversize participation the owner is requesting from the City. Additionally, the following items are attached as required for the oversize participation request: • Copy of Corporate Resolution • Copy of Preliminary Plat • Copy of Title Policy If you need additional information, please contact me at your convenience.
