• Document desired site data requirements for incorporating GI into the environmental site screening process. – Minimize overall data collection efforts and expenses during
site screening and assist early site design efforts. • Develop a “kit-of-parts” for integration into other Meijer
design documents. • GI Site Suitability Manual, GI Design Guidance Manual, and
Supporting Documents and Tools.

• Even number of green and yellow boxes. • Local and WDNR SW requirements and accepted
techniques makes this a good candidate. • Poorly infiltrating soils and the site exemption from
required infiltration makes this a marginal candidate. • Final design decision was a wet pond.
