1 Environmental Site Design Achieving the Promise ceds.org/esd 1

2 The Promise? Cleaner Water + More Growth Benefits 2

3 ESD vs. End Of Pipe Structures 3

4 How ESD Delivers On The Promise 4

5 What Must Happen To Achieve The Maryland ESD Promise Clean water advocates must: Regularly assess ESD compliance; Inform politically-significant constituency of results; then Organize demonstration of public support. Increase inspection-enforcement enforcement capabilities. Restore MDE triennial reviews. Increase incentives for treating runoff from existing impervious surfaces. 5

6 Regularly Assess ESD Compliance 6

7 Initial ESD Concept Plan Review ceds.org/esd 1. Will all impervious surfaces drain to ESD practices? 2. Have aquatic buffer requirements been met? 3. Have Forest Conservation requirements been met onsite? 7

8 2000 MDE Manual Chapter 5 Google: Maryland Stormwater Design 8

9 ESD Practices Practice Category Alternative Surfaces Number of Practices 3 Nonstructural Practices 3 Micro-Scale Practices 9 9

13 Request Access To Project Files 13

14 1. Do All Impervious Surfaces Drain To ESD Practices? 14

15 If All Impervious Surfaces Don t Drain to ESD Practices then, Does the Narrative Document Show the Applicant has Tried to Shift impervious areas to drain to permeable soil; Redirect drainage to permeable soils; Reduce impervious area with Alternative Surfaces and Better Site Design; or Use end-of of-pipe structures. 15

16 2. Are Aquatic Resource Buffer Requirements Fully Met? Calvert County Stream Buffer 16

17 3. Are Forest Conservation Requirements Fully Met Onsite? 17

18 Environmental Site Design Principles Clear the smallest area of vegetation; Avoid steep, highly-erodible soils; Direct runoff away from exposed soil; Quickly apply mulch-grass seed to disturbed soils; Protect aquatic buffers and other sensitive areas; Minimize impervious area; All impervious areas must drain to ESD practices; Increase aquatic buffers and forest. 18

24 Incentives for Treating More Existing Impervious Area Runoff 24

25 Limits Of Disturbance (LOD) Redevelopment Existing Impervious Area > 40% 25

26 Cost Analysis of Proposed District of Columbia Stormwater Regulations 26

27 Land Use Conflicts Best Opportunity to Educate the Public & Decision-Makers 27

28 Winning Full ESD With Equitable Solutions Think negotiation & political action, before litigation; Make the ESD benefits case; Seek to offset increased applicant cost (if any); Work with the applicant & regulators; Demonstrate substantial public support; Lobby key decision-makers; then Move onto the more aggressive aspects of the CEDS Equitable Solutions approach: ceds.org/eqs 28
