Rain Gardens Website

Rain Garden WebsiteIn 2012 NEMO partnered with the Connecticut Fund for the Environment's Save the Sound program to create a rain garden "how to" website, focused on helping Connecticut and New England homeowners build their own rain garden. The Rain Gardens website is meant to be a companion site to both the CT NEMO website and Save the Sound's new Reduce Runoff website.

The Rain Gardens website has detailed information about what a rain garden is and why they are so important. The site is divided into easy to follow steps including how to pick a location and size, check the soil, select plants, how to properly install them, and how to maintain the garden both in the short-term and long-term. The site also features videos that discuss each step, a "cost calculator" to help estimate the cost of installing a garden, and a database of mostly native plants ideal for a rain garden in the Northeastern U.S. Plants can be searched based on several factors including type of plant (perennial, grass, shrub, tree) bloom color and sun exposure preferred. Plants fitting the criteria are then listed along with an image, height and width (full grown), seasonal bloom times and any additional notes specific to a particular plant.

CT Low Impact Developement (LID) Inventory Atlas

Low impact development (LID) is designed to reduce the negative impacts of traditional development on our water resources. The goal of LID is to preservation the predevelopment hydrology of a site. Site-level practices, such as rain gardens, swales, and pervious pavements, are some of the stormwater treatment practices that can be used to work towards this goal.

This website allows you to retrieve LID sites from the inventory by clicking on the interactive map or selecting sites by the LID treatment practice. You can also find companies that design and install these LID practices.

Low Impact Development (LID) Regulations

There are many ways to incorporate innovative stormwater management strategies and low impact development (LID) into local town regulations. This website allows you to explore some Connecticut town and city regulations that have introduced innovative solutions to stormwater management. The list of regulations is not meant to be exhaustive. Alternatively, it is meant to help stimulate ideas on how your town can adopt lower-impact practices that protect water resources.

Eagleville Brook Impervious Cover TMDL Website

TMDL MapIn 2007, the Connecticut Department of Environmental Protection issued the first total maximum daily load (TMDL) in the country based on impervious cover (IC).

What does an "IC-TMDL" mean, and how does one respond to it? This website describes the Eagleville Brook watershed TMDL, a project designed to answer these questions. Go to Eagleville Brook Implementation Site page
