Project Locale
Densely Developed Area
Oak Bluffs Harbor
Oak Bluffs
Year round population approximately
4000 people
Summer population exceeds 25,000
Critical Infrastructure
OB wastewater collection and treatment system serves the heavily populated downtown and commercial areas
Three primary wastewater pump stations serve 90% of the wastewater system, and are located within newly mapped FEMA 100 yr flood plain
Stations have already had flood impacts
Bath House Pump Station
Lake Ave Pump Station
Dukes County Road Pump Station
The Project
Design and construct modifications to
these pump stations to ensure safe
operation during a 100 year flood event
Elevate all electrical service and control
panels above flood elevations
Construct elevated platforms for emergency
generators
Install protective flood panels around pump
stations
Sea Level Rise & Project Design
Design will be based upon a SLR
projection of 3.9 feet by Year 2100
(“intermediate-high” scenario)
Pump Station infrastructure has a
design life of 40 years
40 year SLR projection = 1.5 feet
Budget
Total project cost: $250,000
Match amount: $62,500
Grant award: $187,500
