In late 2010, Community & Environmental Defense Services (CEDS) conducted a survey of local stormwater review officials to learn how well Environmental Site Design (ESD) was working and how it could be improved. We just repeated the survey with some very interesting results. But before getting to that here’s a bit of history that might help put the results into context.
Six years ago, Maryland Governor Martin O’Malley signed the Stormwater Management Act of 2007. The Act required the use of an extremely promising approach to land development known as Environmental Site Design (ESD). Unlike the prior approach, ESD required that consideration of sensitive environmental resources and stormwater management facilities occur at the beginning of site design. ESD also required the use of practices more effective in protecting the suitability of our waters for childhood play, adult recreation, consumption and aquatic ecosystems. In 2009, the Maryland Department of the Environment (MDE) added a new Chapter 5, to the Maryland Stormwater Design Manual, which set forth how ESD was to be applied. In May, 2010 the new ESD regulations took effect.
Following are the major findings from our 2013 survey:
- Of the jurisdictions (23 counties and Baltimore City) asked to participate in the 2013 survey, 14 responded;
- 91% of the jurisdictions that completed the survey feel the overall benefits of ESD are significantly greater when compared to the pre-ESD approach to stormwater management;
- In 2010, 88% of the jurisdictions had found that project review times were significantly greater with ESD when compared to the prior approach;
- In 2013, only 42% still found a significant difference in review times;
- The number of practices per site has tripled with ESD;
- The number of practices in each jurisdiction is anticipated to quadruple in ten years;
- To ensure that this increased number of practices are well maintained, inspection staffing needs to increase an average of 62% over the next decade;
- In late 2010, 492 ESD waivers had been issued, which increased to 556 by 2013; and
- 67% of the waivers were issued by a single jurisdiction, which was 25 times the number issued on average by the other jurisdictions.
