IMPLEMENTING LID • Goal of keeping post-development runoff the same as pre-development can be achieved in many ways • Recommend that developments above a minimum size be required to have a PE certify that runoff will be similar to pre- development condition
QUANTIFYING EFFECTS OF PLAN • Existing flood control ordinance will have some effect in reducing runoff • Not take effect until 2010 because of backlog of platted development • Because most new homes in subdivisions, LID applied to 75% of population growth • Central WWTPs assumed to be used in subbasin 9, with 1 and 10 also candidates
