About the Project
The Jordan Cove Urban Watershed Section 319
National Monitoring Program Project is located in Waterford, Connecticut along the coast
of Long Island Sound. The study began in 1995, and was designed to
determine water quantity and quality benefits of using pollution
prevention Best Management Practices (BMPs)
in a residential subdivision. Monitoring took place for 10 years.
| A Note on Terminology |
At the beginning
of this project, “low impact
development” (LID),
was not a familiar term to most people, although the term “best
management practice” (BMP)
was fairly common. LID embodies an approach of developing
a site, whereas BMP refers to those individual practices
that may be components of LID site design. Therefore,
on this website,
the model subdivision will be referred
to as the “LID
subdivision”,
but when discussing the individual practices used, the
term BMP will be used.

| Project Summary |
The Problem
The project is located in the watershed of
Jordan Cove, which is a small estuary in Long Island
Sound fed by Jordan Brook. The Cove has impaired water
quality based on excess bacteria. Long Island Sound suffers
from hypoxia related to excess nitrogen.
The Goal
The key project goal was to measure the effectiveness
of urban stormwater BMPs in reducing runoff and protecting
water quality.
Specific Objectives
- Reduce sediment, bacteria, nitrogen, phosphorus and
stormwater runoff quantity during and after construction.
- Demonstrate residential BMPs.
- Evaluate selected BMPs (e.g. driveways, lawn management).
