Mr.Bruce Westby,P.E. September 26,2022 Page 2 of 3 • Clear and grub the area of The COR bounded by Sunwood Drive, Bunker Lake Boulevard, Armstrong Boulevard and Center Street, • Strip off topsoil for the above area and stockpile the material, • Dewater the area to allow for deep excavations to occur, • Excavate the pond, placing the material in locations identified within The COR, • Place a 2 ft thick clay liner in the pond from the bottom up to the normal water level, • Fine grade the area of the regional stormwater retention pond, and • Revegetate all areas disturbed by construction. We will provide construction cost estimates associated with the improvements. SCOPE OF SERVICES Our anticipated scope of services will be as follows: • Complete a drone flight of the area to provide a current aerial image of the area.The drone flight will provide a level of accuracy of 0.1 ft horizontal and 0.3 ft vertical.This will allow for accurate estimations of excavations and fill volumes required to construct the Waterfront and move the material to adjacent lots within The COR area. • Update the stormwater model to analyze elevations within the Waterfront and impacts associated with filling existing stormwater ponds across The COR. • Analyze the potential for filling the wetland that was created in the southeast quadrant of Bunker Lake Boulevard and Armstrong Boulevard.This will be completed under a separate contract and the results will be discussed in the updated report. • Analyze previous report assumptions and update proposed horizontal and vertical elevations associated with the roadways and public utilities within The COR area. Develop current construction cost estimates based on the analysis. • Prepare a report detailing the findings of our analyses.This will likely be in the form of an update to previously prepared reports. No geotechnical analysis will be performed for the project, although previous soil borings completed for the area will be reviewed.

We estimate fees will be as presented below: Task Fees Drone Flight $ 2,880.00 Stormwater Analysis $ 7,200.00 Roadway and Public Utility Analysis $ 9,680.00 Report preparation, Including Figures $ 4,420.00 Not-To-Exceed Fees $24,180.00 The fees in the above table represent not-to-exceed costs based on the scope present above.
