Agenda

Meijer Background

• 237 stores in six states • 5 distribution centers and 6 food manufacturing plants

Current LID/GI Practice ST279 Manistee: • Test site for porous pavement • Additional LID/GI practices • Cost competitive • Comparable maintenance

• 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.

Project Goals

Site Suitability – WI site

• 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.
