Project Description

Budget: Funding provided per the West Point Settlement Agreement
Construction begins: 7/1/2012
Project complete: 12/2012

WATER LINE REPLACEMENT
Approximately 800 feet of the 8” water main along Kansas Ave that connects to the existing main in the intersection at the south and north ends of the road is being replaced. The existing east-west main between Kansas Ave and the valve assembly will serve as a carrier pipe for a new 2” service line to the Theater site area, and will supply several quick couplers.

Removal of the remaining service drive paving to the Theater site and restoration is planned. Restoration will consist of the removal of existing utilities and surface features, minor grading, and relocation of bollards. Areas of planting will be identified.

NORTH PARKING LOT MODIFICATIONS
Removal of the west bound lane of the access roadway along the north side of the parking area is proposed to eliminate erosion to the ravine below. The area will be regraded to form a shallow swale for bioretention and water quality treatment of stormwater runoff, and a mulch or gravel path added. The roadway transition from the intersection at the east end of the pavement will be modified to accommodate the removal.

The parking lot modifications include the repair and removal of deteriorated paving and repairs to the storm drain outfall. Areas where the pavement is removed will be restored. The design for the failing drainage outfall and flume on the north side of the road will consist of either a pipe with a portion installed on the surface, or channel modifications consisting of log step-down for a more natural system, or a combination of these two schemes.
