Expiration date: 4/22/2020

The applicant seeks authorization to conduct grading and excavation operations within waters of the United States to modify an unnamed intermittent tributary, for the purpose of increasing capacity, and to better manage the amount of runoff flowing through residential properties. The proposal plans for the improvements of approximately 600 feet of channel, with a modification that includes the widening and creation of a shallow trapezoidal channel, to contain 15-year and 100-year design storms. The modified channel would have a bottom width of six feet, a minimum depth of two feet, and side slopes re-shaped 2:1 (h:v). Also, approximately 184 feet of 2-3 foot tall modular block wall would be installed along the left descending bank to minimize impacts to private property. The vacant lot located at 6906 Roland Blvd. will be used as storage in the form of a floodplain bench.

 

Additionally, the project involves 1800-feet of new gravity sanitary sewer ranging in size from 8-inch to 15-inch and the abandonment and filling of existing sanitary sewer ranging in size from 8-inch to 12-inch. The proposed sanitary sewer will run approximately along the same alignment; however, along Winchester Drive the new sewer will be placed across an unnamed tributary.
