Page 12 of 65 Task 3: Existing Conditions Analysis Background data and existing conditions analysis will be summarized in a single existing conditions presentation to establish the current context. Materials will be shared internally unless otherwise directed. Technical documentation will also be provided in CAD and PDF as indicated below. 3.1 Existing Physical Conditions (partially funded by MTC PSTA) Supported by MTC Priority Sites Technical Assistance funding, existing physical conditions for Sub-Area 1 will be documented and assembled into a base map set for internal reference by the broader Development Plan Consultant Team. The base maps will be provided in a PDF and CAD format with layers that can be edited to serve as background information for multiple types of maps. Refer to final PSTA agreement for final scope for all identified subtasks. A.Base Map Plan Set and Aerial Topographic Survey (partially funded by MTC PSTA Task 2.a) Base Map (MTC PSTA Task 2.a) Supported by MTC Priority Sites Technical Assistance funding, the base map will be informed by title reports (direct cost up to $5,000) and an Aerial Topographic Survey. Consultant will set up ground control and have an aerial survey flown to provide topographical information. The aerial topographic survey will show existing site features such as buildings, parking, and roadway network; contours and topographic features. This survey will be provided in AutoCAD with layers that can be manipulated to serve as a base map. Digital mapping of the aerial photography will be provided at 1”=20’. The consultant team understands that BART will provide recently collected topography, aerial imagery, and digital terrain mapping for its property and B3 will also share existing surveys. This scope of work includes two (2) days to set aerial panels and coordinate control data with the aerial consultant. This aerial topographic survey will be based on the project defined horizontal and vertical datums. This aerial survey is limited to Sub- Area 1. For planning purposes, the Consultant Team will overlay the aerial background with: • Property lines and right of ways (based on information provided by the City/BART/Developer, in acquired title reports or based on approximate record/APN information), • FEMA flood zone overlay, • historically mapped geotechnical/geologic hazards (provided by client), and • major utility infrastructure analyzed in PDA-grant funded Development Plan Task 3.2E • Three sections marked on the aerial topographic survey will be provided with the base plan map set.
