The Tisbury ICD Project arose in 2017 out of a request by the Martha's Vineyard Commission (MVC) to discuss environmental challenges faced by Martha's Vineyard including potential opportunities for EPA SNEP-funded technical assistance to address water quality impacts to Lagoon Pond resulting from uncontrolled nitrogen discharges. As a result of EPA's Sept 2017 meeting with MVC, EPA became aware of stormwater-related flooding and water quality problems in the Town of Tisbury. These problems represented an important, unique and challenging opportunity to address impervious cover disconnection (ICD) in an urbanized context – a further extension of work both EPA Region 1 and the UNH Stormwater Center had been conducting (e.g., EPA's Opti-Tool model; UNH's Berry Brook Dover, NH) but with the added complexity of addressing ICD-related flooding in an urban context having significant topological slope leading down to a business district located near the ocean. The business district experiences chronic (if not acute) flooding on a regular basis.

The goal of the project is to identify, assess and quantify opportunities for the disconnection of impervious cover (IC) within a geographically-constrained urbanized New England community located near the southern New England coastline. The community, the Town of Tisbury (Town), had requested assistance from the EPA Region 1 to address chronic (even acute) flooding and the generally poor transmission of stormwater runoff related to and resulting from IC and older stormwater infrastructure. An equally important project goal is building an understanding and capacity for integrating green infrastructure (GI) and other stormwater control measures (SCM) into municipal land use decision making. This collaborative project is intended to achieve innovative and cost-effective management of stormwater for a broad range of management objectives (e.g., volumetric control (flooding); reuse, resilience and sustainability; control of pollutants and protection of sensitive surface waters).

More information, including background information with links to pertinent information is provided in the documents referenced below. EPA welcomes the interest and input of all Martha's Vineyards towns / communities, as well as the general public that may be interested in stormwater and IC disconnection.

The Tisbury ICD Project was completed on March 27, 2020. The Technical Support Document (TSD) developed under Task 5 provides a best summary of the outcomes of the Project. Additional technical details may be located in the Task 4J Final Report or accessed via deliverables provided for individual project Tasks.
