KELLY-THOMPSON RANCH & THOMPSON ROAD DRAINAGE ANALYSIS
FCE conducted a detailed drainage analysis for a 4.8 square mile watershed area in southern Santa Cruz County. The primary objective of the drainage study was to:
NATIVIDAD CREEK STORM WATER DETENTION FACILITY
ARROYO MOCHO CREEK FISH PASSAGE ENHANCEMENT PROJECT
Fall Creek Engineering brought together a multidisciplinary team of consultants, including John Gilchrist & Associates to conduct a technical study and prepare engineering design plans to restore anadromous fish passage in a reach of Arroyo Mocho Creek, in Livermore, California. The project was completed for the University of California Lawrence Livermore National Laboratory.
ALTO CORRALITOS RANCH STREAM CHANNEL AND BANK STABILIZATION PROJECT
Fall Creek Engineering (FCE) in association with John Gilchrist and Associates prepared engineering design plans and specifications for the channel and bank stabilization project utilizing biotechnical methods to restore a deeply incised stream and eroded bank along a 80 foot long reach of Jesus Creek in Corralitos, California. The project designs include the construction of a four-step boulder vortex weir for grade control, a vegetated redwood log crib wall, and log revetment for bank stabilization. Erosion control and revegetation plans were also prepared for the project. FCE conducted a hydraulic analysis using HEC-RAS to evaluate flood conveyance capacity and to assess shear stress in the channel and along the banks. ARROYO LEON STEELHEAD STREAM ENHANCEMENT PROJECT
Fall Creek Engineering (FCE) with Swanson Hydrology and Geomorphology, JGA and HES developed engineering design plans, specifications, construction bid documents and provided construction supervision for a San Mateo County Resource Conservation District stream restoration project. A steelhead fish barrier (a six-foot diameter and forty-foot long culvert) was replaced with a boulder step-pool sequence and biotechnical bank stabilization measures employing vegetated riprap and log revetment for a perennial coastal stream. A clear span bridge was installed for the access road. FCE performed hydraulic analysis using HEC-RAS to assess flood flow capacity and channel and bank stability under existing and post construction conditions. COWARD CREEK BANK STABILIZATION PROJECT
FCE prepared engineering design plans and construction cost estimates for a biotechnical bank stabilization project on two sites on the stream. The first project includes construction of a 60 feet long vegetated cribwall and the second site includes reshaping the banks and installing vegetated riprap and native plantings on the bank slope and top bank area. The project was completed for the SCCRCD and the landowner. GREEN VALLEY CREEK BANK STABILIZATION PROJECT
FCE prepared engineering design plans and construction cost estimates for a biotechnical bank stabilization project on two sites on the stream. The first project includes construction of a 60 feet long vegetated cribwall and the second site includes reshaping the banks and installing vegetated riprap and native plantings on the bank slope and top bank area. The project was completed for the SCCRCD and the landowner. LOWER WEEK'S CREEK STREAM RESTORATION
Fall Creek Engineering (FCE) has prepared a restoration plan for restoring 1,500 linear feet of Lower Week's Creek to allow for steelhead passage, spawning and rearing habitat. The plan includes the removal of several fish passage barriers including culverts, portions of concrete lined channel and an in-stream pond, and restoring riparian and in stream habitat conditions. The plan includes creating approximately 900 feet of new stream channel, restoring sinuosity in the channel and including overbank terraces to improve flood conveyance, and replacing several culvert with clear span bridges or arched and bottomless culverts. The project was completed for Mazzanti Carnations, Inc. MUNICIPAL WATER DIVISION
Conducted a technical study employing GIS to map critical ground water recharge in the municipality of San Pedro Sula. The study recommended land use restrictions to protect groundwater resources in the basin, as well as presented BMPs to enhance and maintain groundwater recharge areas in rapidly developing portions of the area. MUNICIPAL WATER DIVISION
Developed land use regulations and development standards to protect groundwater resources in the San Pedro Sula area, which were incorporated in the Land Use Master Plan for the County. STONE VALLEY OAKS SUBDIVISION
Prepared a technical study to evaluate the potential hydrologic and water quality impacts resulting from erosion, sedimentation and urban stormwater runoff from a proposed 99 acre residential development. The study identified and recommended BMPs to mitigate erosion and water quality impacts resulting from the project. UCSC HUMANITIES AND SOCIAL SCIENCES FACILITY
Fall Creek Engineering (FCE) conducted a drainage analysis to evaluate the potential environmental impacts associated with the proposed development of a UCSC Humanities and Social Sciences facility. FCE examined site hydrology and storm water runoff under various development conditions, and prepared infrastructure and mitigation recommendations based upon the results. |

Fall
Creek Engineering (FCE) in association with John Gilchrist &
Associates and Joni L. Janecki & Associates, and the California
State University at Monterey Bay's Watershed Institute, prepared
engineering design plans, specifications, site restoration plans and
construction cost estimates for a multi-function flood control project
for the City of Salinas. The project is currently under construction,
will restore 1,500 lineal feet of Natividad Creek, and create 17.5
acres of palustrine (freshwater wetlands) for flood control, riparian,
stream and wetland habitat enhancement. Historically, the project site
was a freshwater wetland that formed a portion of the Carr Lake Basin,
the predominant drainage area for the Northern Salinas Valley. The
wetland facility is contiguous with the Natividad Creek Parkway and
will include a network of trails to provide for recreational and
environmental education opportunities.
A
comprehensive hydrologic and hydraulic (H&H) study was completed by
FCE to analyze flood flows under existing and post project conditions.
The H&H was conducted to size the outlet control structure, design
the stream channel morphology and to evaluate flow conditions for adult
and juvenile anadromous fish through the facility. FCE employed state
of the art engineering design tools including three-dimensional surface
modeling and biotechnical engineering methods to develop a
comprehensive flood control and restoration project that was supported
and approved by several state and federal resource agencies, including
the California State Department of Fish and Game, California Regional
Water Quality Control Board, U.S. Fish and Wildlife Service, the
National Marine Fisheries Service, U.S. Corps of Engineers, Natural
Resource Conservation Services, as well as several local environmental
and community groups.
The
project will involve the replacement of an at-grade road that is
preventing passage of steelhead and trout in the stream and restoration
of approximately 200 linear feet of stream channel. The at-grade road
will be replaced with a clear span bridge. The channel will be restored
to a natural grade and a sequence of vortex boulder weirs will be
installed to control the grade of the channel and to enhance fish
habitat in the stream. The site will also be revegetated with native
riparian plants to restore the wetland/riparian habitat in the project
area.
The
project was completed under the direct supervision of a Technical
Advisory Group comprised of different department staff at the lab
facility.
