Mr. Bruce Westby, P.E. April 7, 2023 Page 3 of 5 • Extents of improvements, • Tree removals, • Excavations, stockpiles, and Lot grading, • Wetland impact strategy, • Waterfront configuration, • Roadway layouts, alignments, and grades, • Stormwater strategies, and • Other key issues. To date,we have completed several topographical surveys. We will augment our current data with additional data to compile a full comprehensive base map.The attached exhibit displays our topographic survey strategy. We will then create a base layout showing the improvements and schedule a second meeting with the City.A final layout will be prepared to show the improvements prior to beginning final design on any one component. We have anticipated additional meetings and communications will be required as we work through the preliminary design process.This time has been included for the task. Once final layouts are determined we will begin the right-of-way vacation and plat process.The evolution of The COR area has led to Ramsey Parkway and Center Street rights-of-way likely being obsolete.The final parcel and road layout will require vacation and re-platting.The proposed plat will allow the City to convey available land for development. Geotechnical and Environmental Services We are proposing to augment our design team with Braun Intertec (Braun). Braun will complete geotechnical exploration and review for roadway construction and assist in analyzing the excavation and fill placement of the material located in the regional storm water retention pond. Generally, Braun's services will include the following: • Ramsey Parkway—Seven borings and pavement design, • Zeolite Street—Four borings and pavement design, • Center Street—Three borings and pavement design, and • Regional Storm Water Retention Pond & Mass Grading—55 borings in addition to the 9 borings that already exist within The COR.Assistance with planning for the mass grading of The COR. Environmental testing of materials located in low areas, or other potentially contaminated areas. • Complete a Phase I Environmental Service Assessment (ESA) Continued assistance during the construction phase will allow Braun to also assist with preparation of documents related to the individual sites within The COR that the City can provide to potential developers.The documents will indicate material type, bearing capacity, allowable loads, and foundation recommendations. The attached Fee Proposal spreadsheets detail the hours and staff associated with preliminary design.
