CODE: C TYPE: CONSENT PUBLIC NO HEARING: SUBJECT: Authorize the Execution of a Storm Water Facility Maintenance Agreement with The Ranches East, L.P., for Property Located in the A.H. Hawkins Survey North of Haslet Roanoke Road and West of Ridgetop Road at No Expense to the City of Fort Worth (COUNCIL DISTRICT 2) RECOMMENDATION: It is recommended that the City Council authorize the City Manager to authorize the execution of a Storm Water Facility Maintenance Agreement with The Ranches East, L.P., for property located in the A.H. Hawkins Survey, north of Haslet Roanoke Road and west of Ridgetop Road, at no expense to the City of Fort Worth. DISCUSSION: The Ranches East, L.P., is the owner of approximately 5.2 acres of property upon which it will construct one detention pond facility (DOE No. 6214). The detention pond will serve the Lost Spurs Apartments Addition. This facility is necessary to limit storm water run-off generated on the property to pre-development levels. The facility is also limiting the public runoff from Westport Parkway between Alta Vista Drive and Haslet Road. The terms of the Maintenance Agreement assure the proper maintenance of one detention pond facility by The Ranches East, L.P., at no cost to the City. The facility is located north of Haslet Roanoke Road and west of Ridgetop Road. The facility is located in COUNCIL DISTRICT 2, Mapsco 8P. FISCAL INFORMATION/CERTIFICATION: The Financial Management Services Director certifies that this action will have no material effect on City funds.
