REV: 11-07-23 SK detailed assessment and analysis of the boundary lines. While performing the field work associated with the topography, Consultant will conduct field research for primary monumentation to establish boundary resolution. Once the research and reconnaissance has been completed, Consultant will perform a boundary determination, which includes an analysis of the assembled evidence with respect to its relationship to the title and other documentary evidence. The requirement for a Record of Survey is not known but is assumed to be required. However, Consultant assumes that either sufficient existing monumentation is not recovered, a material discrepancy is discovered, or any other provisions requiring a Record of Survey as stated in Section 8762 of the Professional Land Surveyors Act of the State of California are encountered. Consultant will prepare a Record of Survey to fulfill their legal and professional obligation. Consultant proposes a Time and Materials (T&M) clause to accommodate any additional efforts, time, or resources that may be required based on the initial findings. This clause ensures that the scope and cost of the services provided by Consultant remain aligned with the actual requirements, providing transparency and fairness to the City and the Consultant. Optional Task 5 – GREEN INFRASTRUCTURE DESIGN • Conceptual BMP Layout • Concurrent with Task 4 described, Consultant and sub-consultant, Callander Associates Landscape Architecture, Inc. (CALA), will perform conceptual stormwater treatment Best Management Practices (BMP) sizing calculations and develop a preliminary BMP layout for each pump station alternative to satisfy Provision C.3 of the Municipal Regional Permit (MRP). Given the location and size of the stormwater treatment area is not yet defined, this proposal assumes that one contiguous, lined bioretention planter BMP will be utilized to treat stormwater runoff from the site and the BMP will be in the immediate vicinity of the improvements. Off-site treatment is not anticipated. The BMP will be fed by gravity flow alone and stormwater treatment will not require pumping. Consultant and subconsultant do not anticipate structural engineering will be required for the edge condition, and hydromodification controls are not anticipated to be required. Consultant and subconsultant will prepare narrative text to be included in the Alternatives Analysis and Basis of Design Report (BOD) that documents the BMP sizing calculations and preliminary layout. • 60% BMP Design: Consultant and CALA will refine the stormwater treatment BMP sizing calculations and progress the BMP design to the 60% level of completion. Consultant and CALA will add BMP-related information to the plans, specifications and cost estimates that are described under Task 6. Anticipated elements include the BMP soil layers, underdrain, cleanout, overflow structure, liner attachments, edge condition, irrigation point of connection, irrigation equipment palette and ATTY/AGR.2023.241/BKF Engineers (Price Tract Pump Station Design) (Page 31 of 68)
