discharges from Carnegie SVRA through the use of site-specific structural and nonstructural
BMPs in order to protect and improve water quality while providing high-quality
OHV recreational opportunities. Elements of the SWMP include public education and
outreach, public involvement and participation, illicit discharge detection and elimination,
construction site storm water management, post-construction storm water management,
and pollution prevention/good housekeeping. The SWMP also included an OHV element
dedicated to discussing management goals and activities for maintaining OHV trails and
facilities as they relate to meeting the water quality objectives.
Since 2012, several elements of the SWMP have been implemented. The following section
describes the Resource Management Area (RMA) rehabilitation and public outreach and
participation elements of the SWMP.
Resource Management Areas
The RMAs are discrete zones established to better plan and implement management
activities of areas that share common characteristics. For the most part, the RMAs were
divided by sub-watersheds and cover the entire SVRA. The RMAs are connected to each
other through a trails network and is part of the overall Carnegie SVRA Trails Management
Program.
Each RMA restoration project starts
with a planning process that considers
several items including trail layout,
connectivity, emergency access, user
interest, enforcement strategy, education
methods, buffer zones, and a timeline
for completion of the project. The

East Kiln RMA shows no obvious signs of off-trail riding
with identifying any trails that have proven to be sustainable and that do not convey high
concentrations of storm water elsewhere. These trails are usually incorporated into the
RMAs trail network. Trails that have been identified as erosive per the soil conservation
program’s dataset are eliminated from the trails network and the area is restored.
Eliminating these trails from the network often involves using heavy equipment to place soil
back on the hillside to bring the hillside back to grade. Once in place, the soil is protected
using BMPs from the OHV BMP Manual for Erosion and Sediment Control. Typically, the
BMPs used are a combination of straw wattles that reduce the velocity of concentrated
water and hydromulch that protects the soil from precipitation. If the hydromulch machine
is unable to access the area, straw is used to cover the bare soil. Staff are trained in
proper implementation techniques and the work is supervised by experienced restoration
specialists. These efforts result in an overall reduction in trail density for the area, along
