COFFELL Agency Reviewed By CITY OF COPPELL DRC REPORT Review Date COP'FELL Comments Preliminary Water & Sewer Line - 1. Verify that the 24" and 12" lines are shown properly; make sure you are tying into the 12" line, not the 24" line. 2. For the connection of the sanitary sewer to the existing stub out: verify that the stub out is really there, and that the etevation works for your proposed sewer line. 3. You are proposing a 6" sanitary sewer line and our minimum standard is an 8" line. 4. Each individual property should have a separate water and sewer tap. 5. Remove the General Note that "water service is %" with bullhead connections." Sewer services are 4" but our minimum water tap size is 1". We can altow a %" meter but the tap is a 1" minimum. 6. Valve spacing needs to be no greater than 500' per the Subdivision Ordinance. 7. At the end of this water line you show it to go from 8" to 6" however our minimum line size is 8". 8. This is a 900' dead end waterline. I suggest you tie into the 8" waterline in Bradford Drive which is northeast of your project and would require some additiona~ offsite construction. The City owns a portion of the adjacent property and would entertain the option of an easement for waterline construction. Also adjacent is the TXU easement where you may be able to locate an offsite waterline.
