• Reconnoiter and locate subdivision PRM's, PCP's, block corners and lot corners, as necessary. • Perform site specific topography as required by the project engineer to include visually obstructed areas from LiDAR, as built of all drainage structures, IRFWCD and subdivision culverts, driveway culverts. • Locate all trees and vegetation within the Oslo Park Subdivision road right of ways only and rear lot line easement plus 5 feet outside of the easement. • Perform cross sections of IRFWCD drainage canals. • Coordinate with and observe underground utility locations by others. Office Tasks: • Calculations, boundary determination, differential level adjustments, coordination with field and office staff • Prepare survey base map of Oslo Park Subdivision geometry based on platted and observed information. • Prepare topographic survey of project site utilizing 3D LiDar surface prepared by LJA as base map and field observed topography to create overall model and contour map. Topographic survey to also include locations all improvements, above ground (visible) utilities, vegetation, driveways (to garage apron), culverts, mailboxes, etc. in the right of way. • Prepare control sheets with 100 feet stationing for engineering design plans. • Prepare sheets, title blocks and drawing sets for engineering design (approx. 85 sheets at 40 scale —11 "x 17"). • Prepare cover sheet, plan and profile sheets of right of ways and plan view rear lot swale/easement. • Input owner provided utility locations into survey base map. • Quality Assurance and Quality Control LiDAR • LJA Surveying will perform LiDAR topographic survey with the required check shots as specified by state regulations. LJA will produce a topographic survey with 1 foot contours and mapping of all planimetric's within the project limits. • CAI will coordinate and assist LJA Surveying with placement of Ground Control Points/Aerial Targets for performance of LiDar of project site. • Establish horizontal and vertical control of Ground Control Points/Aerial Targets. • Perform ground truthing shots for verification of LiDAR created 3D surface. B. Geotechnical Investigation: CAI will coordinate sub -soil testing of the existing roadways through our sub -consultant KSM. Paving section recommendations will be provided by KSM. (Reference attached KSM Engineering and Testing scope of work and fee proposal dated 10/20/2023). C. Investigate Permitting Requirements: CAI will conduct formal pre -application meetings with St. Johns River Water Management District (SJRWMD) and Indian River Farms Page 3 of 6
