d.  Use permeable surfaces that allow water infiltration.           STORMWATER AND
               e.  Use generous site landscaping (and depressed areas) to
                  absorb site runoff.                                              TRASH ENCLOSURES

                  incorporating ‘laundry to landscape’ and other greywater         enclosures is closely related to

               j.  Design landscaping and irrigation to prevent non-
                  stormwater runoff.


        7.15  Perform maintenance on LID systems when necessary.
               a.  Maintain permeable pavement to prevent clogging by
                  vacuum sweeping the surface, replacing permeable
                  media between pavers and/or drilling small holdings in
                  areas of ponding to assist in drainage.
               b.  Check for ponding water (less than 48 hours), dead or
                  diseased plants and accumulated trash.


        7.16  Use a stormwater management feature as a site                       Use rainwater as an amenity by
               amenity.                                                           directing stormwater to planted

               a.  Use rainwater as an amenity by directing stormwater to
                  planted islands and other landscaping.
               b.  Include a detention area as part of an outdoor public
                  space scheme for a site when feasible.
               c.  Incorporate plazas, courtyards and patios into and
                  around stormwater management systems.
               d.  Consider incorporating a green roof to enhance a
                  project (reduce energy consumption in the summer
                  and winter), while also helping to improve stormwater
                  impacts.
