7.11  Select appropriate LID Best Management Practices
               (BMPs) for the site.
               When incorporating LID features into the design of a
               building and/or site, consider the following:
                  •  Consider the watershed in which the project is located.
                  •  Consider the existing runoff system around the site.
                  •  Incorporate and design new LID systems and features
                      to work in concert with and improve the existing runoff
                      system.

                                                                                  Incorporate a natural drainage way

               treatment measures that are most conducive to that
               location.
               a.  Consider alternative site layout techniques to reduce
                  the total amount of impervious area. This may include
                  designing compact, multi-story structures, clustering
                  development and creating shared driveways or
                  pathways.
               b.  Minimize the amount of surface parking.
               c.  Use rainwater as a resource to reduce runoff and to be
                  retained on-site for irrigation purposes, where possible.
               d.  Use drainage as a design element, incorporating                Consider the use of LID principles
                  vegetated swales, depressed landscape areas and                 including bioretention or other
                  bioretention areas where possible.                              planted paving systems.
               e.  Maximize choices for mobility, accommodating
                  alternative modes of transportation to automobiles.
               f.  Identify self-treating areas such as green roofs or large
                  landscaped areas to remove pollutants.

        Include a stormwater management feature such as a bioretention area or
        a raingarden.
