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
