Storm Water
"The storm water structure on Main Street [at right] successfully and creatively solves our spring flooding problem, and provides space for a small public park. As always, CES, Inc. has done superbly.”
- Dan Foster, Town Manager, Town of Fort Fairfield

Federal, State and local statutes and ordinances set several Storm Water Management guidelines that must be followed on any developed land. For example, most developments require storm water quality standards to be met. Some projects also require that post-development peak storm water flow cannot be higher than pre-development peak flow.

Development permits require detailed analysis of storm water quality treatment and pre- and post-development storm water runoff hydrology. First, a Watershed Study is performed to determine roughly where storm water is being generated, conveyed, and discharged. Then post-development conditions are similarly modeled to evaluate and design measures to create a site design that, when completed, allows a post-development hydrology study to demonstrate discharges similar to the watershed study for undeveloped conditions. The Storm Water Runoff Study, or Hydrology Study, is performed using HydroCAD^® software. Best Management Practices (BMPs) are used to treat the storm water for removal of pollutants and sediment.
