Project: Old Reservoir Management CPA Category: Recreation Amount Requested: $55,000 Amount Recommended: $55,000 CPC Vote: Approval (9 -0) Project Description: This project is being proposed to reconstruct the gatehouse /outlet structures and dredge the retention pond at the Old Reservoir (Old Res). Because the existing gatehouse is located within the Old Res, it is often underwater and inaccessible for operation and maintenance during heavy storm events, leading to extensive flooding and eroding of walking trails and the beach. The gatehouse and outlet structures are important for maintaining the water level in the Old Res. Proper operation of these structures helps to protect the earthen dam and keep suitable water levels for recreation activities such as swimming and fishing. The outlet structure is not functioning properly because of underground damage, causing a backup of water into the Old Res which prevents controlling the rate of exiting water. Dredging the retention pond will help to provide more water storage capacity so that during large storm events the Old Res will not overflow and cause damage. This project is in line with the Recreation Department goals for the Old Res. The Conservation Commission has approved an "order of conditions" for this project. Project Goals and Objectives: • Construct a new gatehouse structure outside of the Old Res that will be accessible for maintenance and allow for proper management of water levels. • Construct a new outlet structure to help regulate the flow of water from the Old Res into the surrounding area to prevent erosion and flooding. • Dredge the pond area to increase the storage capacity during heavy storm events. Project Benefit: The Old Res is an important recreation facility providing both passive and active recreation opportunities for the residents. The Old Res also provides water storage for drainage throughout the area. The preservation work being proposed will help to restore and maintain the major water control structures for the Old Res. Proper control of the water in the Old Res will help to reduce potential flooding, erosion and property damage. Funding Request: The project requests $55,000 of CPA funding. The funds will be used to hire qualified contractors for the gatehouse /outlet structure construction ($35,000) and for dredging the pond ($20,000). The Town's Engineering Department will oversee the project. 10
