BACKGROUND A. Introduction The City of Lakeport is seeking a qualified professional firm to perform a planning study relating to drainage requirements in the Forbes Creek Neighborhood. The firm will analyze the hydrology of the drainage basis and examine the adequacy of the various existing facilities, identify deficiencies, propose potential locations for detention facilities, and provide design flows for each reach of the system from the headwaters to Clear Lake. The review will include street drainage features and make recommendations regarding the location of various street improvements including drainage facilities including inlets, culverts, curb, gutter, cross gutters as well as sidewalks and paving. The focus of the potential improvements is drainage related. The environmental, botanical, and cultural study shall focus on outlining specific elements at each location which will require additional studies during the design of the recommended improvements. Special focus shall be placed on existing and potential detention facilities. B. Background In May 2012, RBF Consulting provided a report for this neighborhood. A copy of the report is available as indicated in the reference documents section of this proposal. The report is attached as an Appendix. The purpose of this study was stated as follows: The purpose of this study is to provide recommendations for improving the Forbes Creek neighborhood while preserving the characteristics that residents value. The study not only outlines street, drainage, and sidewalk improvements, but also offers creative solutions to neighborhood issues and provides a realistic implementation program. Furthermore, as the first neighborhood study in Lakeport, it provides a basis for understanding how the city’s residential areas may be improved and maintained. A Storm Drainage Master Plan was prepared in June 1980 by Barrett, Harris & Associates. An electronic copy of the study is available as indicated in the reference documents section of this RFP. The study has not been updated. This study shall update and replace this older master study for the study area. The report shall include all branches and feeders to Forbes Creek including those to the north and south of the study area. On the downstream end, the study will extend east beyond Forbes Street past Main Street to Clear Lake. However, the proposed improvements including detention facilities shall include the entire drainage area. Improvements relating to street features including culverts, drainage structures, curb, gutters, sidewalks and pavement shall be limited to the original study neighborhood boundary areas. II. PROJECT DESCRIPTION INTRODUCTION The project has three distinct tasks: Hydrological Study; Analysis of Biological, Botanical and Cultural Resources; and Cost Estimates. Hydrological Study The study consists of all of the work necessary to develop hydrological data for the study area and determine design flows for 10, 25, 50 and 100 year events. Design flows shall be prepared for each segment. Segments shall be defined by change in design flows due to the addition of additional drainage channels or elements. 2 | P a g e Detention facilities, both existing, enlarged or potential shall be explored to minimize downstream flows and necessary up sizing of existing facilities where possible. A cost benefit ratio to these improvements shall be included in the third task. Analysis of Biological, Botanical and Cultural Resources The analysis shall consist of evaluating the potential impacts to the biological, botanical and cultural resources which may be influenced or impacted by the recommendations of the hydrological study. Detention basins are of particular concern. Specific areas of study for future project implementation shall be identified. Detailed studies of each element are not included as part of this study. Cost Estimates The study shall provide estimated quantities and costs for each necessary improvement type for each identified improvement segment. Normally, segments will be block to block. Estimate shall be provided in a multi-tab Excel spreadsheet format with a consistent formatting for various types of work. The cost analysis shall also provide a separate cost/benefit analysis comparing detention facility cost compared to improvement savings of downstream facilities (such as culverts). PROJECT LOCATION The project location is indicated on the attached Forbes Creek Neighborhood Improvement Study by
