EPA's National Stormwater Calculator

EPA's National Stormwater Calculator (SWC) is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States (including Puerto Rico). Estimates are based on local soil conditions, land cover, and historic rainfall records.

The Value of Green Infrastructure

In clarifying how to assign value to potential green infrastructure benefits, this guide can assist decision-makers in evaluating options for water management. A more clear view of GI's values will help communities decide where, when and to what extent green infrastructure practices should become part of future planning, development and redevelopment.

Watershed Resources Registry
An interactive mapping tool to characterize and prioritize natural resource management opportunities using a Watershed Approach.

EPA Green Infrastructure Design and Implementation Resources
Provides access to design manuals and design tools, as well as resources addressing construction and operation and maintenance. Common design challenges are also addressed, and a few resources for homeowners are provided.

NOAA Digital Coast – Sea Level Rise Viewer

Being able to visualize potential impacts from sea level rise is a powerful teaching and planning tool, and the Sea Level Rise Viewer brings this capability to coastal communities. A slider bar is used to show how various levels of sea level rise will impact coastal communities.

Philadelphia Green Streets Design Manual

The Green Streets Design Manual outlines what types of green stormwater infrastructure (GSI) practices are appropriate on various street typologies, provides standardized design details, and lays out the necessary design review and construction inspection processes. Moving forward, design professionals, engineers, planners, and developers can utilize the approved design standards and procedures therein to expedite green street development in Philadelphia.

Save the Rain - Onondaga County, NY

The "Save the Rain" program is a comprehensive stormwater management plan intended to reduce pollution to Onondaga Lake and its tributaries. During wet weather events, stormwater flows into the local sewer system, causing heavy flow periods that can overload the system.
