The
Lahontan Project, Truckee,California

This planned
development has approximately 741 acres of land with 43 acres of jurisdictional
wetlands, 315 acres of open space including an 18-hole golf course, and 383
acres of residential lots and roadways. Of the 43 acres of wetlands, only 0.51
acre were impacted due to the project.
Since 1992, H&C, Inc. has been
responsible for baseline water quality data collection and data analysis to
establish discharge standards for the proposed project. H&C, Inc. has also
been responsible for watershed analysis to determine secondary impacts to
wetlands due to the quality of water discharging into wetlands thereby
preserving wetland integrity. Additionally, the impacts from channelized urban
storm runoff and the resultant sedimentation, erosional deposition and nutrient
loading from waters discharging into the wetland have been evaluated. To
mitigate these secondary impacts H&C, Inc. designed a best management plan
to cover the 741 acre property. H&C, Inc. was responsible for preparing and
obtaining approval of the following:
- Wetland delineation, design and
construction of mitigation wetlands
- Rosgen stream classification
- Baseline water quality collection
and analysis
- Data analysis to establish
primary water quality discharge standards
- Watershed modeling to determine
storm water runoff
- NPDES Permit
- Chemical Application Management
Plan
- Best Management Practices Plan
- Construction implementation
- Avoidance analysis
- 401 Lahontan Water Quality Certification
- An approved Nationwide Permit
Additionally, H&C conducted a
stream restoration plan for Martis Creek through the project site that
encompassed the use of hydraulic geometry relationships, analytical
determination of stable channel dimensions and a sediment impact assessment. The
project resulted in additional riffle-pool complexes and a stable meandering
stream course and increased floodplain volume to meet strict regulatory
requirements.
