Capital Projects

Stormwater capital improvement projects (CIPs) are construction projects that replace or improve old stormwater drainage systems to protect water quality and reduce the risk of flooding. CIPs typically include stormwater facilities like treatment swales, vaults, and catch basins that remove pollutants from stormwater. They may also include new beach outfall structures that protect the shoreline from erosion or reduce maintenance requirements. Capital projects are designed to reduce the risk of flooding by improving stormwater flow capacity. BBWARM has a CIP program based on the Birch Bay Comprehensive Stormwater Plan and Subwatershed Master Plans. Read more about our capital improvement projects below.

Birch Bay & Pt. Whitehorn Road Drainage Improvements

Birch Bay Drive & Pt. Whitehorn Road Drainage Improvements Phase 1

Project Description:  In December 2017, the failure of a corrugated metal outfall pipe on Birch Bay Drive caused a significant slope failure on a steep bluff to the shoreline, posing a critical public safety issue. The replacement of this outfall was scheduled for construction in 2021, but this pipe failure called for emergency action. Temporary repairs were installed immediately, with the majority of the final repair constructed in early January 2019 (see photo sequence). In May 2019, an additional storm drainage line will be installed near the top of the bank toward the roadway to complete the project.

Birch Bay Drive & Pt. Whitehorn Road Drainage Improvements Phase 2

Project Description:  This project will improve drainage along Birch Bay Drive by installing an upsized storm pipe conveyance system along Birch Bay Drive between Pt. Whitehorn Road and Holeman Ave. This project will also construct a new outfall off of Pt. Whitehorn Road into an exiting pond as the existing outfall ditch to the Beaver Pond is becoming heavily incised and eroded.

The proposed system is designed to convey the 100-year storm event and the new pipe sizes will vary from 12" to 24" in diameter, with approximately 25 new catch basins.

The project design is nearing the 100% design level and all environmental permits will be submitted in May 2019. Underground utility conflicts have been identified and relocation efforts by the affected utilities will begin soon. Construction is anticipated to being in early September 2019 and will require 2 months to complete, weather dependent.

The aerial map shows the regions where the new stormwater infrastructure will be constructed for the project.
