Info

• Limit clearing and grading of forests and native vegetation at a site to the minimum amount needed to build lots, allow access, and provide fire protection. • Promote riparian buffer areas as part of stormwater management planning. Source: Planning for Green River Corridors, Oakland County Planning & Economic Development Services. Wide buffer maintained during residential construction Source: Huron River Watershed Council Stormwater Functions and Calculations Any portion of a site that can be maintained in its presettlement state by using this BMP will not contribute increased stormwater runoff and will reduce the amount of treatment necessary. Calculation methodology to account for this BMP is provided in Chapter 9. Volume Protected riparian buffers are not to be included in the disturbed stormwater management area when calculating runoff volume (Chapter 9 and Worksheet 3). Any portion of a riparian buffer area that is mitigated or revegetated/reforested should be included in the disturbed stormwater management area, but may be granted credit in accordance with the applicable BMP for native revegetation, soil restoration, minimize soil compaction, riparian buffer restoration, or minimize total disturbed area. Peak rate Runoff from the riparian buffers may be excluded from peak rate calculations for rate control, provided that runoff from the riparian buffers is not conveyed to and/ or through stormwater management control structures. If necessary, runoff from riparian buffers should be directed around BMPs and stormwater pipes and inlets by means of vegetated swales or low berms that direct flow to natural drainageways. Water quality improvement Water quality is benefited substantially by avoiding negative impacts which otherwise would have resulted from impacts to riparian buffers (e.g., loss of water quality functions from riparian buffers, from wetland reduction, etc.). Cost The costs of protecting riparian areas relate to a reduction in land available for development. However, most riparian areas are located in wetlands or floodplains, restricting the amount of buildable area. LID Manual for Michigan – Chapter 6 Page 94
Designer/Reviewer Checklist for Protect Riparian Buffer Areas References ITEM YES NO N/A NOTES Define municipal programs requirements or resources for riparian buffer protection, if any Based on above and relevant sources, establish riparian buffer protection standards for development site Map riparian resources at the site which need buffer protection Apply Zone1/Zone2/Zone3 determinations; adjust for steep slopes and/or other natural/made factors. Overlay development program onto site, avoiding/minimizing Riparian Buffer Zone impacts. Provide for Riparian Buffer Zone maintenance?
