Hi folks concerned and involved with stormwater quality & quantity issues and better development designs.
I found the following article in Stormwater Journal very interesting and informative in a more detailed manner. They used a number of different approaches, some for sandy soils, clay soils, slope limited sites where they appropriately elongated out with contour strips, etc!
I think that for us locally in Sonoma County we could really use some very explicit stormwater bio-filtering/infiltration monitoring and public educational demonstration sites!
While many projects are being built, to my knowledge none are actually designed to be accessible and educational- while producing scientific data on the efficacy of different designs based on our unique local conditions. If people know of local projects that are designed to do this please let me know.
I have not looked at it enough yet, but does anyone have an opinion of the new landscaping makeover in front of the Board of Supes Office? Is it just a traditional “xeri-scaping” plan or did they actually do anything to harvest all that roof water?
Thanks to Paola of SPAWN for alerting me to this article!
In the mitigation of cerebral imperviousness I strive to percolate,

Monitoring the Success of Infiltration Requirement: Combining regulation with outreach and demonstration sites by Paul E. Moline
Alternative stormwater techniques are becoming more widely used in jurisdictions around the country as local, state, and federal regulations increase. Infiltration, filtration, and bioretention practices are being considered more often as an option or a supplement to more traditional wet-pond treatments. These alternatives are not always easily implemented, however, due to resistance from the development community, skepticism from the planning and engineering community, lack of regulation, climate, soil conditions, and inexperience in construction. Implementation in suburban Minnesota has been slow to progress. Carver County, MN, a rapidly developing Twin Cities suburban area, has been working on this implementation since 2002 and has learned that a combination of uniform regulation, flexible techniques, demonstration, monitoring, and a willingness to evolve has proved successful.
This article covers the results of monitoring; the methods used in outreach to the stormwater management audience (developers, engineers, contractors, and landowners); and the types of practices installed, including the use of “pond shelves.” The approach of combining regulations with outreach, technical assistance, stakeholder input, and demonstration sites has led to successful implementation of innovative stormwater practices and has applicability to other jurisdictions…
