Storm Water Management Plan in Action
The OHMVR Division initiated an aggressive
storm water management program at
Carnegie SVRA in an effort to protect
the park’s natural resources, improve
water quality, and meet the requirements
of the NPDES and the Clean Water Act
(CWA). In order to achieve these water
quality objectives, a number of projects
and programs have been planned and/
or are being implemented. The OHMVR
Division initiated a study of the Corral Hollow
Carnegie SVRA storm water management
watershed in 2004. The primary goal of the assessment was to provide the OHMVR
Division, Carnegie SVRA staff, and community stakeholders with an understanding of
historical occurrences that have shaped the watershed. Based on the assessment’s
findings, the OHMVR Division developed recommendations to reduce future erosion and
sediment concerns and return Corral Hollow to a properly functioning watershed, while
maintaining visitor satisfaction and preserving the area’s historic value. These conclusions
and recommendations are presented in the Final Corral Hollow Watershed Assessment
(California State Parks 2007, 1-4).
The findings from the watershed assessment were used to develop a number of
recommendations designed to reduce erosion and sediment issues through innovative
BMPs and an active adaptive management framework focused on meeting water quality
objectives. This framework includes continual assessment of erosion and sediment
generators, implementation of appropriate BMPs, ongoing monitoring and evaluation
of these actions, and plans for long-term maintenance to ensure the success of these
actions. Other components of the storm water management program include the ongoing
development and implementation of the Trails Management Plan; the implementation,
monitoring and maintenance of projects associated with the Soil Standard; implementation
of annual species surveys and habitat restoration
activities related to the HMS program; and use
of the OHV-specific BMP manual for selecting,
implementing, and maintaining appropriate BMPs.
The next phase of the storm water management
program included the development and
implementation of a SWMP in 2012. The purpose
of the SWMP is to reduce or eliminate pollutant
