p:+ry a. Research County benchmark and record maps within project limits. b. Datums i. Vertical: Orange County Surveyor's NAVD88 ii. Horizontal: Orange County Surveyor's CCS-83, Zone VI Horizontal Datum c. Topographic field survey: i. Locate existing centerline monuntentation for basis of bearings. ii. Collect topography from parking lot to existing buildings and limits determined by Tatsumi. iii. Collect all surface features within project limits (curb & gutter, driveways, sidewalks, walkways, existing landscape improvements, trees, shrubs, visible irrigation equipment, valves, etc.). d. Drafting: i. Prepare topographic base sheets, 1" = 20' scale with 1' contours in AutoCAD drawing format including all survey information collected for design of landscape improvements. This mapping will be digital and will serve as the base for all future planning and design of this project. 6. A preliminary utility investigation will be conducted in the form of reviewing the project plans, underground utility plans, and geotechnical information provided for the subject project by the City. This task is conducted to confine that there are no underground utilities which would have to be addressed in the planting. Prepare sketch Opportunities and Constraints analysis will be conducted to quickly determine areas of opportunities. Constaints such as underground utilities, visual clearance of buildings and signage, visitor queueing patterns, and pedestrian movement patterns will be addressed in this analysis. 8. Concept Design: A conceptual layout of the new landscape elements including planting, accent lighting and concrete mow strips (if required) will be prepared in an illustrative manner. If significantly differing avenues of design are identified, additional concept layouts will be provided. For each concept, a schematic cost estimate will be provided. These concepts and < estimates will be presented to the City for its review and comments. Tatsumi will assist the City f=' in selecting a concept which meets most of the project's goals and objectives. Refinements to this preferred concept will be made for final approval by the City. If a new signage design available or pending, Tatsumi will coordinate the location and type of planting as well as the accent lighting with the signage designers. Electrical load and voltage drop calculations will also be performed to insure that adequate power is available for the new electrical demands of the irrigation controller and accent lighting, 9. Upon final approval of the concepts and estimates by the City, Tatsumi will prepare construction documents which conform to the City of Santa Ana standards and requirements. These will include: a. Demolition Plan (or possible tree preservation plan). Proposal: On Call Landscape Architectural Consultant Services City of Santa Ana Tatsumi and Partners, Inc.
