The stormwater module builds on a portal platform developed by Critigen and CH2M Hill for assessing the solar energy potential of rooftops. A simi-lar solar module was developed for DDOE that allows users to look at so-lar electric or solar water heating, as well as energy conservation projects (Figure 4). The stormwater module is a Web implementation of the Center for Water-shed Protection’s Rainfall Runoff Model, with property data pre-populated in an easy-to-use template (Figure 5). The tool supports nine different stormwater proj-ect types, which lets property owners decide the best way to reduce stormwa-ter runoff from their property, including: • Simple projects such as rain bar-rels or cisterns, tree planting, rain gardens, and bay scaping • More involved projects such as green roofs, pavement removal, permeable pavement, amended soils, and stormwater infi ltration Sizes, flow rates, prices, illustrations, instructions and SIZING CALCULATOR online at www.FairclothSkimmer.com J W Faircloth & Son Inc.
