Modeling and permit drawings detailing structural and non-structural LID practices in the design phase will refine the master plan and ensure a sustainable stormwater master plan is to be implemented properly. In addition to the stormwater plan, opportunities to address and convey important information about the stormwater management system may exist on the cover sheet; site layout; grading and erosion control plans; sewer and water plan; landscape plan; mechanical, electrical, and plumbing plans; and details sheet -- in other words, every sheet associated with sitework. Since many of these approaches will be new to your community, extra detail is required.
Design of LID facilities should be informed by the natural and built environment both on- and off-site, as well as client/stakeholder preferences for cost and long-term operations & maintenance considerations. Design is usually an iterative process when used to optimize water quality protection, stream bank erosion reduction, appropriate flow conveyance, and flood storm mitigation.
