Richmond Wwtp and Collection System Weekly RICHMOND WWTP AND COLLECTION SYSTEM MONTHLY OPERATING REPORT SEPTEMBER 2014 EXECUTIVE SUMMARY General • The treatment plant remains in need of high priority capital improvements for both the grit removal system and electrical infrastructure. Cost estimates and task authorizations have been developed and submitted to the City for these projects. Need for both projects poses critical wastewater treatment reliability concerns. • Construction of the Wet Weather Storage Facility is progressing. Veolia Richmond project staff remains involved in weekly meetings, plan reviews and related oversight activities. WWTP Operations • There were no NPDES permit violations during the month. • There were no blending events during the month. • The monthly bioassay passed with 100% survival of the fathead minnows. • Three phoned in odor complaints were received during September. The first on 9/10 was called in from 221 East Scenic Ave. The caller is a repeat complainant and her call was investigated by staff. The other two calls on 9/9 and 9/29 were from residents considerably distant from the treatment plant and calling about odors from the sewer. Both complaints were investigated and the residents contacted by staff. • There was one north fence H2S alert measured during September. The alert were not linked to any plant activities however it was observed using the handheld calibrated Jerome meter that the stationary meter was not responding to field test results. The meter was referred to the vendor for repairs and then placed back in service.

  • Pt. Isabel-Stege Area
    Tales of the Bay Shore -- Pt. Isabel-Stege area Geology: The “bones” of the shoreline from Albany to Richmond are a sliver of ancient, alien sea floor, caught on the edge of North America as it overrode the Pacific. Fleming Point (site of today’s racetrack), Albany Hill, Pt. Isabel, Brooks Island, scattered hillocks inland, the hills at Pt Richmond, and the hills across the San Pablo Strait (spanned by the Richmond Bridge) all are part of this Novato Terrane. Erosion and uplift eventually left their hard rock as hilltops in a valley. Still later – only about 5000 years ago -- rising seas from the melting glaciers of our last Ice Age flooded the valley, forming today’s San Francisco Bay. The “alien” hilltops became islands, peninsulas linked to shore by marsh, or isolated dome-like “turtlebacks.” Left: Portion of 1911 map of SF Bay showing many Native American sites near Pt. Isabel and Stege. Right: 1853 U.S. Coastal Survey map showing N. end of Albany Hill, Cerrito Creek, Pt. Isabel, and marshes/ to North. Native Americans: Native Americans would have watched the slow rise of today’s Bay. When Europeans reached North America, the East Bay was the home of Huchiun Ohlone peoples. Living in groups generally of fewer than 100 people, they moved seasonally amid rich and varied resources, gathering, hunting, fishing, and encouraging useful plants with pruning and burning. They made reed boats, baskets, nets, traps, mortars, and a wide variety of implements and decorations. Along the shellfish-rich shoreline they gradually built up substantial hills of debris – shell mounds -- that kept them above floods and served as multipurpose homesites, burial sites, refuse dumps, and more.

  • Community Participation and Creek Restoration in the East Bay of San Francisco
    Louise A. Mozingo Community Participation and Creek Restoration and Recreation, had been inspired by an article of Bay Area Community Participation and historian Grey Brechin on the possibilities of daylighting creeks Creek Restoration in the East in Sonoma County north of San Francisco (Schemmerling, 2003). Doug Wolfe, a landscape architect for the City of Bay of San Francisco Berkeley, proposed that a short culverted stretch of Strawberry Creek crossing a new neighborhood park in Berkeley then culverted, be opened or “daylit.” As a first step in proposing Louise A. Mozingo the unprecedented idea, Wolfe named the new open space Strawberry Creek Park. As he later reported, this “lead to the ABSTRACT question ‘Where is this creek?’ My answer was that it was ‘Twenty feet down and waiting’” (Wolfe, 1994, 2). Controversial The creeks of the upper East Bay of San Francisco in the extreme, Wolfe found political support from Carol have been the location of two decades of precedent Schemmerling, and David Brower, founder of Friends of the setting creek restoration activities. This discussion will Earth, and a city council member. With vocal citizen support review the essential role of both citizen activism and at public meetings the radical concept prevailed. The notion NGOs in the advent of a restoration approach to creek that a reopened creek could be an asset rather than a hazard management. Beginning with small pilot projects to proved to be a lasting inspiration (Schemmerling; Wolfe, 2-3). “daylight” a culverted creek and spray paint signs on street drain inlets, participation in the restoration of the Also in Berkeley, a small but telling community education act East Bay creeks has evolved into a complex layering took place on city streets.

    LOW IMPACT DEVELOPMENT (LID) SITING METHODOLOGY: A GUIDE TO SITING LID PROJECTS USING A GIS AND AHP A University Thesis Presented to the Faculty Of California State University, East Bay In Partial Fulfillment of the Requirements for the Degree of Master of Arts in Geography By Andrew Jack October 30, 2012 Copyright Andrew Jack © 2012 ii ABSTRACT The purpose of this research project is to develop a straightforward and cost-effective methodology that local governments and nonprofit organizations can use to identify sites that have the greatest potential for Limited Impact Design (LID) stormwater management projects. The methodology is applied to watersheds in Western Contra Costa County, California. A review of LID manuals guided the selection of site suitability criteria and professional opinions from two stormwater managers guided the ranking of the criteria. The Analytical Hierarchy Process (AHP) was used to convert these rankings into coefficients which were then applied to the chosen criteria. A geographic information system (GIS) was used to develop site suitability rankings of the study area. Maps depicting suitable sites for LID placement were generated using this methodology. These maps act as a guide that the aforementioned groups can use for LID project planning. The top ranked sites, suitable for LID, identified by the methodology were primarily areas with large parking lots and building footprints. These sites should be targeted for LID projects because they are often the largest contributors to hydrograph modification and have most significantly altered the site hydrology. iii LOW IMPACT DEVELOPMENT (LID) SITING METHODOLOGY: A GUIDE TO SITING LID PROJECTS USING A GIS AND AHP By Andrew Jack Approved: Date ____________________________ _______________________ Dr.

  • Section Presents an Evaluation of the Potential for Increased Erosion, Sedimentation, and Runoff Due to the WTTIP Projects
    3. Environmental Setting, Impacts, and Mitigation Measures 3.5 Hydrology and Water Quality 3.5.1 Approach to Analysis This section presents an evaluation of the potential for increased erosion, sedimentation, and runoff due to the WTTIP projects. The analysis of water quality impacts is based on field observations and a review of existing EBMUD permits for discharges. In general, implementation of the WTTIP would not have direct long-term effects on the hydrology or water quality of regional and local surface waters. However, short-term construction impacts could result in erosion and sedimentation or discharge of construction-related pollutants to local creeks, causing water quality effects. Diversion of flood flows could also occur. Operational discharges of chloraminated water could cause adverse water quality effects. However, through compliance with existing regulations and established project procedures, as well as mitigation measures specified in this section, construction and operational impacts would be less than significant. 3.5.2 Setting Surface Water Bodies, Drainage, and Flooding The WTTIP project sites lie within the regional drainage of San Francisco Bay; the majority of project sites are located in Contra Costa County, and one project is located in Oakland (Alameda County). Precipitation is variable between East and West Contra Costa County due to the county’s distinct topography and proximity to the California coast. The rain-shadow effect of the East Bay Hills and Mt. Diablo is evident in the average annual rainfall levels, which are highest just east of the crest of the Berkeley-Oakland Hills (33.75 inches per year) and lowest in East County (9.75 inches per year).

  • Tidal Marshes Are Either Exposed to the Open Bay Or Are Protected from Wave and Tidal Energy by Offshore Mudflats
    Assessment Chapter Contra Costa County Adapting to Rising Tides Project Natural Shorelines Natural shorelines include a range of shoreline types and conditions. Fully tidal marshes are either exposed to the open Bay or are protected from wave and tidal energy by offshore mudflats. At the other end of spectrum are muted tidal marshes and ponds, that are protected from the Bay by berms and levees and have water levels controlled by tide gates and other structures. These systems provide an array of ecosystem service benefits, the loss of which will ultimately diminish the value of the Bay Area as a desirable place to live. Natural shorelines help reduce incoming wave heights, protecting shoreline structures from wind, waves, and tidal energy. Natural shorelines provide buffers to neighboring communities of all kinds, including disadvantaged and vulnerable communities, from sea level rise and storm surge. Their loss can place shoreline communities at greater risk of flooding by increasing the likelihood that structural shoreline protection is overtopped or fails, and can increase the cost of maintaining, repairing and upgrading these already expensive structural protection assets. In addition, many natural shorelines, including tidal and muted tidal marshes and ponds, have been restored and represent a significant financial investment. Many of these areas provide habitat to a number of state-listed or federally threatened and endangered species as well as migrating and wintering birds that rely on them for breeding, foraging, and high tide refuge. Additionally, they offer opportunities to view wildlife, provide access to the shoreline, and offer scenic and aesthetic benefits. Tidal Marshes Historically, tidal marshes keep pace with sea level rise by accumulating mineral sediment and by moving upward and landward in the tidal frame.
