Long-Term Hydrologic Impact Analysis

Local Government Environmental Assistance Network
2011

L-THIA estimates changes in recharge, runoff, and nonpoint source pollution resulting from past or proposed development. It estimates long-term average annual runoff for land use and soil combinations, based on community-specific long-term climate data. In the basic model, the only inputs are: location (state and...

Recycled Content (ReCon) Tool

U.S. Environmental Protection Agency
2010

This tool estimates the greenhouse gas (GHG) emission and energy benefits associated with increasing the recycled content of materials purchased or manufactured. The tool compares baseline recycled content for common materials – including  glass, wood, metals, plastics, paper, PVC, and fiberboard – to...

Rainwater Harvesting Calculator

State of Washington Department of Ecology
2010

This Excel-based calculator was developed to help residents of Washington State size and test scenarios for rain water harvesting systems based on the typical climate. The calculator assumes that water is harvested entirely from roofs and that 80% of precipitation falling on roofs is captured. Inputs are the...
