Wetland Studies and Solutions
Wetland Studies and Solutions is a LEED gold certified facility with an array of LID
practices on the ground -- green roof, irrigation cistern, toilet cistern, bio-swale, pervious
pavers, pervious concrete, porous asphalt, gravel pave and a rain garden. The presentation will
include a discussion of the pros and cons of design, cost and maintenance after four and a half
years of experience, as well as how this relates to the new draft federal Stormwater Guidance
and the last version of the Virginia Stormwater Management regulations.
11:00 The Hopewell’s Landing Experience – Marc Aveni, Watershed Branch Chief, Prince
William County Department of Public Works, and Chuck Williamson, Stream Protection
Manager, Prince William County Department of Public Works
Section 1 of Hopewells’s Landing is a subdivision of single-family homes on quarter-acre lots,
which was designed with individual lot bio-retention, grass swales, narrow streets with open
ditch sections rather than curb and gutter and the preservation of open space to decrease
impervious cover, promote infiltration and increase the time of concentration of stormwater
run-off. Prince William County Watershed Management Branch has been studying these Low
Impact Development techniques since 2005 as a way to meet more stringent stormwater
regulations as well as learn more about citizen acceptance of LID practices in individual yards.
Also, overcoming some problems with the initial installation of rain gardens provided a
opportunity for lessons learned.
