The Fourth Annual Berkeley River Restoration Symposium

The Fourth Annual Berkeley River Restoration Symposium

Saturday 9 December 2006
112 Wurster Hall
University of California, Berkeley

Sponsored by the Department of Landscape Architecture and Environmental Planning (Beatrix Farrand and Child Funds), and the Water Resources Collections and Archives. Free and open to the public.

ABOUT THE CLASS: Restoration of Rivers and Streams (LA227)

Taught since 1992 (the longest-running course devoted to river restoration at a major research university), this course emphasizes understanding of underlying goals and assumptions of restoration and integration of science into restoration planning and design. Students review restoration plans and evaluate completed projects. In addition to lectures and discussions by the instructor, students, and an extraordinary set of guest lecturers drawn from the active restoration community, the principal course requirement is an independent term project involving original research and a presentation at this Symposium. The term projects are peer-reviewed, revised, and ultimately added to the permanent collection of the UC Water Resources Collections and Archives. Restoration of Rivers and Streams is normally taught by Professor Matt Kondolf, but was taught this semester by Mark Tompkins. Paul Atwood (Water Resources Collections and Archives) developed the website and on-line access to class research papers. Funds for refreshments and reproduction of this Program were graciously provided by CH2M HILL.

ABSTRACTS

Post-project appraisal of the Martin Canyon Creek Restoration Project  / Jesse Roseman, Wayne Wagner
Martin Canon Creek drains 1.08 mi² near the City of Dublin, California. In 1999 a restoration project consisting primarily of erosion control and gradient control structures was completed on Martin Canyon Creek. We conducted a post-project appraisal (PPA) of the Martin Canyon Creek Restoration Project, comparing current conditions with the project’s listed goals and as-built conditions. We took photos of erosion control structures and grade control structures at established photo monitoring points and compared them with as-built photos to qualitatively compare and evaluate performance of structural components of the project. In addition, we surveyed a longitudinal profile and a selected cross section to compare current channel slopes and geometry with pre-project and as-built conditions. The project is largely performing as designed in terms of protecting neighboring structures, although some bank stabilization structures show signs of deterioration. Grade control structures also appear to be stable and performing as designed, with significant local sedimentation upstream of most grade control structures. However, Grade Control Structure #4 shows significant signs of deterioration and could be prone to failure without maintenance in the near term. We suspect that the deterioration of this structure is related to its location in a bend and a downstream channel slope that exceeds stated design guidelines, however further research is required to fully understand the performance of this structure. Overall the dynamic equilibrium slope that guided the design of the project appears to have been achieved with fewer structures than originally proposed.

Post-project appraisal of the East Branch Alamo Creek realignment project / Randi Adair, Patricia Perasso
The East Branch of Alamo Creek drains a small watershed in the Windermere Estates subdivision near San Ramon, California. A channel relocation and step-pool creation project designed by Philip Williams and Associates was constructed on the East Branch of Alamo Creek in 2001. The project also included revegetation and creation of off-channel floodplain wetland areas. We evaluated the performance of this project, primarily with respect to its objectives to stabilize creek banks, reduce channel incision, and decrease sediment loads in the creek, particularly in light of recent urbanization in the creek’s watershed. Our study, conducted in November 2006, tracked fluvial geomorphological changes to determine the success of the restoration project given its stated goals. We surveyed channel cross sections and a longitudinal profile and conducted qualitative assessments of vegetation conditions along restored sections of the creek. We also looked at supporting design documentation used to justify the restoration project in order to assess whether the plan was appropriate and adequate for addressing pre-project degradation. We found that despite some localized bank erosion and channel bed scouring, the creek has remained relatively stable and has not incised or migrated excessively. We also concluded that although this project was a functional solution for controlling a creek in an urban area, the project did not truly restore the creek to a natural, healthy condition; rather it created a new creek corridor that is still adjusting in response to local hydrology and succession of vegetation.

Baxter Creek Gateway Park: Assessment of an urban stream restoration project / Judd Goodman, Kevin Lunde, Theresa Zaro
We conducted a post-project evaluation of the Baxter Creek Gateway Restoration Project located in a small, urbanized section of creek in the City of El Cerrito, Contra Costa County, California. The project was conducted to restore sinuosity, provide aquatic and riparian habitat, and enhance public access to a 700-foot section of channelized stream. Our assessment of this project’s performance (completed less than a year after the project was constructed) evaluated the restoration effort’s progress and provides a baseline for future assessments of the project as it matures. Assessment approaches and techniques included physical surveys of the creek’s longitudinal profile and several cross sections, facies mapping of the creek’s bed structure, estimation of a sediment budget for the site’s drainage basin, observations of site users, interviews with community stakeholders, visual evaluation of vegetation success rates, and photo documentation of current site conditions. We found that the creek’s planform was similar to the plans but detected some bank erosion as well as bed material transport from the upstream to downstream end of the project. The current sediment yield for the urban catchment is much less than during historical conditions. Based on bed structure measurements, sediments will need to be managed at the site as frequently occurring flows were predicted to move bed sediment in the restored reach. The quality of potential vegetative and aquatic habitat within the project site has increased as a result of the restoration, but the site’s surrounding culverted creek and urbanized landscape limit the feasibility of fish and amphibian colonization. Exotic riparian vegetation grew prolifically despite the fact that crews removed all vegetation during construction, planted only natives, and a citizen group frequently removed invasives. The multi-use trail and interpretive signs contributed to a successful recreational community space, but the trail needs improvements in connectivity beyond the project site. The existing monitoring plan for the restoration project includes important abiotic and biotic factors, but we recommend installing a permanent stream gauge at the site, monitoring flood overflow conveyance in adjacent streets, conducting physical surveys of the longitudinal profile and established cross sections, and regular facies mapping.

A Restoration Plan for Islais Creek, San Francisco, CA / Lucas Griffith
Historically water accumulated on the shallow soils of the San Bruno Mountains and flowed into Islais Creek -- the largest watershed of San Francisco. Expansion and development in the watershed over the past one-hundred and fifty years altered the original character of the creek and eventually forced it into an underground combined sewer system. I developed a restoration plan for Islais Creek that recognizes the heavily urbanized context of San Francisco but provides an opportunity to restore the symbolic presence of the creek and its history. I analyzed historical maps and surveys to identify a representative baseline for the historical character of Islais Creek. and used standard hydrologic and hydraulic methods to determine a design discharge and appropriate channel geometry for a reach of daylighted and restored creek "scaled-down" to drain a small fraction of the original Islais Creek watershed. I also incorporated educational aspects in my restoration plan to provide opportunities to teach potential users of the site about fluvial processes and aquatic ecosystems, and to enrich their connections to the site.

Using LIDAR to assess rivers and streams and monitor restoration projects / Toby Minear
Terrestrial LiDAR (Light Detection and Ranging) techniques have significant advantages over traditional survey methods, including faster data acquisition, better-resolved data, and reduced costs, yet they have not been adequately tested for river or stream applications. Together with Rune Storesund, a Ph.D. student in the UC Berkeley Civil and Environmental Engineering program, I have been investigating the use of Terrestrial LiDAR techniques for surveying geomorphic features in rivers, including restoration projects on rivers and streams throughout the US. Preliminary results from pilot projects indicate that Terrestrial LiDAR is a significant improvement over traditional survey techniques at most sites, although sites with heavy vegetation or extensive water can pose problems and must be carefully evaluated before applying LiDAR at the site
