Richard Lyons - Mojave River Watershed Mitigation Bank
DMEC is assisting Mr. Lyons in developing a large wetland mitigation bank in the Mojave Desert at East Cronese Lake, which is located at the north central portion of San Bernardino County, just north of Interstate 15.   The proposed Bank Site is over 400 acres, almost entirely within the bed of East Cronese Lake, which is the terminis of the Mojave River.   The Bank Site supports Chenopod Scrub vegetation types, and extensive stands of Tamarisk, an invasive exotic shrub that will be eradicated to significantly improve wetland functions at the Bank Site.   DMEC conducted a number of surveys and studies in support of applying to the U.S. Army Corps of Engineers, California Department of Fish and Wildlife, the U.S. Environmental Protection Agency, and the Regional Water Quality Control Board to establish a wetland restoration and preservation bank to allow Mr. Lyons to offer wetland credits to individuals and agencies that need to mitigation for impacts to wetland habitats and functions for projects in the Mojave Desert   DMEC conducted surveys of the botanical resources, and performed a delineation of jurisdictional waters and wetlands. DMEC also developed a regional model to measure functionality of desert playa wetlands, using 19 different desert playas as reference sites, and used that model, following the Hydrogeomorphic Assessment Method developed by the Corps, to determine the level of functionality of the six depressional wetland functions of the East Cronse Lake Bank Site. DMEC used the recently release Episodic Streams module of CRAM to assess wetland conditons of the Mojave River Delta portion of the Bank Site.   DMEC also prepared a detail habitat restoration and monitoring plan for the Bank.   These studies are summarized in a Prospectus, that is being used by the Interagency Review Team to evaluate the feasibility and appropriateness of estabishing the Mojave River Watershed Mitigation Bank.
Below is a PDF copy of the reports prepared for the proposed mitigation bank.
CRC Enterprises - Queen of Angels Catholic Church Biological Assessment, Santa Barbara County
David Magney Environmental Consulting (DMEC) was contracted to conduct a biological assessment of the Queen of Angels Church property in the Mission Hills area north of Lompoc, California.   The Church needs to legalize previous lot splits and the County of Santa Barbara must comply with CEQA, hence a biological resources assessment was required.   DMEC biologists surveyed the church property, half of which contains a church, school, rectory, and relative facilities, while the other half is undeveloped and containing Burton Mesa Chaparral, a rare plant community.   DMEC found the undeveloped portion to contain six rare vascular plant species (Arctostaphylos purissima, Arctostaphylos rudis, Ceanothus cuneatus var. fasciculatus, Diplacus lompocensis, Horkelia cuneata ssp. puberula, and Mucronea californica) and a rich lichen flora.   Interestingly, there were more species of lichen identified onsite then vascular plants, which is quite unusual.
Below is a PDF copy of the biological assessment report, "Biological Assessment of Queen of Angels Church, Lompoc, California" (January 2013), covering the entire church property.
Wild Wolves Preserve - Rare Plant Survey, Kern County
DMEC conducted a botanical survey of the lower elevation areas of The Wildlands Conservancy's 97,000-acre Wind Wolves Preserve in southwestern Kern County to determine the locations of rare vascular plants.   The Preserve in located and very southern terminus of the San Joaquin Valley and up the north slope of the San Emigdio Range.   Field surveys were conducted during the spring and early summer of 2010 over about 27,000 acres of the Preserve.   DMEC was contracted to conduct the botanical surveys through the California State University, Stanislaus, to provide the resource information to the Wild Wolves Preserve resource managers.   A total of 581 vascular plant taxa were observed at 200 locations.   Six special-status species were found during the survey, and are documented at 33 locations on the Preserve.

Tejon Ranch Conservancy - Lebec, Kern & Los Angeles Counties
The Tejon Ranch Conservacny, headquartered in Lebec, California, contracted DMEC to perform botanical surveys of five large aquisition areas of the very large Tejon Ranch, in the Tehachapi Mountains, in both Kern and Los Angeles Counties.   The Tejon Ranch Conservancy wished to know what botanical resources were present, including special-status species, and vegetation alliances (communities) were present in each of the five aquisition areas, to be purchased in fee, or preserved through a conservation easement at some time in the future.   The acquistions areas are known as: White Wolf, Old Headquarters, Michener Ranch, Bi-Centennial, and Tri-Centennial, totalling over 62,000 acres.   Field surveys were conducted from mid-March through late July 2009, which was a very good year for wildflowers in the grassland areas especially.
DMEC collected floristic and vegetation data at 342 data points across the five acquisition areas: 64 in Tri-Centennial, 91 in Bi-Centennial, 32 in Michener Ranch, 77 in Old Headquarters, and 78 in White Wolf.   A total of 877 taxa were noted, of which 668 tax have been positively identified.   Sixteen (16) special-status vascular plant species were documented in one or more of the acquisition areas.   The vegetation consisted of 76 mappable/identifiable vegetation alliances, of which 39 are newly described based on DMEC's surveys.   A PDF copy of the botanical survey report of the five Tejon Ranch areas, "Flora of the Tejon Ranch Conservancy Acquisition Areas, Tejon Ranch, California", is available below.
Lyons Canyon Ranch - Newhall, Los Angeles County
D.R. Horton - Western Pacific [Housing] Series proposed a residential development on the Lyons Canyon Ranch property in Lyon Canyon, located immediately west of Interstate 5, south of the Stevenson Ranch development, and north of Towsley Canyon Park.   The Lyons Canyon Ranch project site contains portions of two Los Angeles County designated Sensitive Ecological Areas (SEAs): Lyon Canyon SEA 63 and Santa Susana Woodlands SEA 20.   DMEC prepared the EIR for the project and has prepared a wetland delineation and biological constraints report for the project.   The DEIR was made available in October 2006.
Below are PDF copies of the SEA constraints analysis report, "Significant Ecological Areas Biological Constraints for Lyons Canyon Ranch, Newhall, California" (September 2005) and the U.S. Army Corps of Engineers-verified "Delineation of Jurisdictional Waters and Riparian Habitats for Lyons Canyon Ranch, Newhall, California" (June 2004).
SEATAC commended DMEC for its "very good, thorough Biological Constraints Analysis" report, which contained an "excellent" vegetation map.
North Vineyard Greens Development Alternatives Analysis and Wetland Mitigation and Monitorning Plan
DMEC assisted developer Peter Daru obtain permits to fill wetlands at the proposed North Vineyard Greens development project site, located in the North Vineyard Station Specific Plan Area of southern Sacramento County, California, approved in 1998.   The approved housing development will provide approximately 750 homes, single-family and multiple-family units in the middle of the specific plan area.   DMEC prepared an Alternatives Analysis as required under Section 404(b)(1) of the Clean Water Act as part of the Individual Permit application to the U.S. Army Corps of Engineers (Corps) to fill at total of 1.60 acres of seasonal wetlands, including 0.15 acre of vernal pool wetlands.   Based on that analysis, the Corps required 1.75 acres of onsite mitigation for impacts to seasonal wetlands (1:1 creation of non-vernal pool seasonal wetlands and 2:1 creation of vernal pool wetlands).   DMEC then prepared the mitigation and monitoring plan to satisfy permit application requirements, proposing to create 1.75 acres of seasonal wetlands onsite in disturbed annual grassland habitat under existing electric transmission lines.   Corps Regulatory Project Manager, Andrea Jones, wrote of the plan, "I am impressed with the thoroughly researched background information provided for context.   This is a much more 'together' plan than I am used to seeing".
The USFWS issued a No Jeapordy Opinion based on the information DMEC developed, pursuant to Section 7 of the Endangered Species Act.   The Central Valley Regional Water Quality Control Board issued a Water Quality Certificate in response to DMEC's application for the project.   The Corps issued the Individual Permit in March 2009.
