Soil Interpretations for Storm Water Practices
What is the Focus?
Connecticut Cooperative Soil Survey information is used to prepare GIS maps
that are a screening tool for successful selection and implementation of best
management practices. The maps (for a town) can be used by town planning,
regulatory, and engineering staff; state and local agencies, consultants,
realtors, and individual land users. They can help guide the selection of storm
water practices that best fit the soil conditions in comprehensive planning on a
town or watershed basis. They provide guidance for site plan reviews or
preliminary site selection and design. The maps are based on soil and site
characteristics including depth to water table and bedrock, permeability, and
slope to predict suitability for four commonly used storm water practices
(infiltration systems, detention basins, and perennial and intermittent wetland
systems). Properly functioning storm water management systems help protect
ground and surface water quality while preventing increased surface flows as
well as the nuisance and hazards caused by failing practices.
What Does NRCS Offer?
GIS Maps (and the protocols used for the map), soil ratings, training on uses
and limitations of the Maps.
What is an Example of Soil Based Recommendations for Storm Water Practices?
GIS maps showing soil performance for four commonly used storm water
management systems were included in a resource analysis provided for the Town of
Guilford’s Community Landscape Analysis. These and other analyses are being used
by the town to implement their Plan of Conservation and Development.
