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

15

• 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

16

Impervious Cover / Water Quality / LID

• Budget

• Table 7.1 $ 100,000• 2014 WP $ 100,000

• No identified decisions or deviations

Impervious Cover / Water Quality (WQ) / Low Impact Development (LID)

• 2013 work plan activities• Beginning stages of the creation of the overall LID plan through

public involvement and meetings with City of New Braunfels

• 2014 work plan• Further development of LID/WQ program in watersheds

draining to critical habitats• Implementation of the LID/BMP program utilizing public

involvement and feedback
