^~^ Kimley-Horn ~ and Associates, Inc. July 12, 2007 Mr. George Farrell, page 3 south side of Valley Avenue. The location of the drainage facilities will also include a structure inventory indicating invert elevations, pipe sizes, pipe types and general direction of flow. It is not anticipated that potholing of utilities will be required for this project and is not included in this proposals. - A random sampling of the topographic mapping provided by the City. The verification and acceptance of the existing topography will be the responsibility of KHA/City. - The data collected will be based on the same datum as the existing topographic mapping. - Permanent horizontal and vertical control points will be established to facilitate the addition of supplemental topographic information and for use as a basis for construction control Task 3 -Project Research and Coordination KHA will research the project in order to develop the project base plans and to develop engineering services in conjunction with Task 2. The investigation will include record plan research and field investigations. In addition to the topography and files received at the meeting of June 15, 2007, KHA requests as-built roadway plans, utility plans (water, storm drain, sanitary sewer, etc.), right of way maps and development plans for the adjacent subdivisions. KHA will send Utility Information Request Letters to all applicable utility companies requesting current as-builts, schematic maps, etc. The response mapping will be used to supplement the project utility base map. The KHA team will physically walk the project site. The project review will be used to visually evaluate any noticeable or potential roadway design and/or construction issues, including grading conflicts, drainage issues, utility conflicts, etc. In addition, KHA will take the opportunity to verify existing record plans, utility responses, and survey information. Kimley-Horn will produce a photo log of the project site. BSK, the KHA team Geotechnical Engineering firm, will conduct R-Value testing at two locations within the vicinity of the project to perform R-Value tests on the existing soil. The soil samples will be collected from two hand auger borings drilled to a depth of about 5 feet below the ground surface. The ground surface at the two locations would be within a foot of the top of the pavement grade along Valley Avenue. This approach would eliminate the need for lane closures and the associated cost and disruption of traffic. The borings will be located in the lawn-covered landscape areas located along both sides of the street. The borings will be logged by an engineer from BSK in general accordance with the Unified Soil Classification System (ASTM D 2487). Prior to the start of the field investigation, USA will be notified to mark any utilities in the planned drilling locations. KHA will prepare a pavement design technical design memorandum that will include the findings from the tests, locations of samples, and pavement structural section alternatives and recommendations. Task 4 -Conceptual Designs Based on the sketches provided to KHA by the City at the June 15, 2007 meeting, we will develop conceptual designs for the project. KHA will investigate and bring forward the best one or two viable options for: S:UNarketing\_Proposal & SOQ\Pleasanton\Santa Rita and Valley\Updated Letter Proposal.doc
