Low Impact Development (LID) & MS4 What is LID? LID in the HCP is an incentives based program that allows citizens to participate in improving the quality of the runoff that occurs in and around watersheds draining to Landa Lake. How does LID in the HCP differ from MS4? LID program in the HCP concentrates on opportunities for stormwater quality enhancement in areas draining to critical habitats. The MS4 program is a city wide city funded program. 14
LID focus Public education is focused on citizens within watersheds draining to critical habitats Long term establishment of program efficiencies based on water quality monitoring Rebate program for LID features in areas just upstream of critical habitats Website development of the habitat and LID education relationship Pilot and Test projects BMP s New technologies for improving water quality 15
