Case Study: Title The second page of the fact sheet includes a Michigan case study highlighting several features of the use of an individual BMP. Each case study includes a description of the project, as well as several site considerations including: Project Type Soil Conditions Estimated Total Project Cost Maintenance Responsibility Project Contact Case Study Site Considerations LID Manual for Michigan – Chapter 6 Page 60
BMP Fact Sheet Cluster Development Cluster development (also known as open space development) concentrates development on smaller lots on a portion of a larger site. Clustering allows the site planner to avoid resource sensitive and constrained areas at a site, such as steep slopes and water-sensitive areas including riparian buffers, wetlands, and floodplains without sacrificing the level of development. Clustering reduces the amount of required infrastructure and various development-related costs. Clustering lends itself to residential development, with greatest potential in municipalities where large-lot residential development is typical. Clustering can reduce total impervious area and total disturbed areas at development sites, thereby reducing stormwater peak rates of runoff, reducing total volume of runoff, and reducing nonpoint source pollutant loads.
