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.


 Pervious concrete infiltrates rainfall at the source.
  Contained planters intercept, then evaporate, rainfall
and are a cost-effective way to beautify anyplace.
  Ecoroofs intercept & evaporate rainfall and greatly
extend roof life.
  Infiltration planters are a great alternative to manage
runoff when it can't be prevented.
