|Field staff locate infrastructure, such as this abandoned outfall, to update inventories of the county's stormwater system.|
The Stormwater Needs Assessment Program (SNAP) assesses watershed conditions, identifies problems and opportunities for stormwater projects, and recommends specific actions to help meet the Department of Environmental Services mission of strategically protecting and enhancing our natural environment.
A standard set of assessment and monitoring tools are applied as appropriate to each sub-watershed in the county. Problems are identified and lists of opportunities are compiled for capital planning evaluation, internal referrals for corrective action, and recommendations on how to better manage water resources.
The SNAP recently completed its first five-year cycle in March 2011, producing thirty-six SNAP reports covering 68 county subwatersheds. A few highlights from this cycle include:
- 80 miles of stream corridor inventoried and assessed for problems and potential solutions
- 15 stormwater capital projects scheduled for construction by 2012
- 100 stormwater facility maintenance issues referred to Clark County Public Works
- 30 streamside trash dumps removed
- 90 landowners contacted with information to help them solve problems discovered during stream inventories
During 2011 the Clean Water Program will revise the SNAP, applying lessons learned in the first cycle, in preparation for the next five-year assessment beginning in 2012.
