Discussion regarding Whispering Coves Phase I proposed modifications. No action taken. Mr. Jacobson provided an overview as described below: Forward Development Group approached City about modifications to the Whispering Coves Phase 1 construction project. The modifications requested are due to a value engineering analysis to reduce the Phase 1 limits (and costs) of their proposed development. Please note that the Developers Agreement  was approved by the Council on March 9, 2020 contingent on City Attorney review. On Thursday May 28, 2020 City Engineer and Director of Public Works meet virtually with the development team regarding value engineering concepts. Some of the modifications proposed are as follows: 1. Reduce mass grading limits 2. Reduce the size of the phase from 56 to 30 residential lots 3. Minor changes to the sewer, water, and storm utility plans 4. Defer storm water pumping station (building and internal mechanicals) a. Intake structure and force main will be constructed 5. Change the grading limits of proposed wet ponds Staff provided feedback on the value engineering concepts and also requested updated engineering plans and storm water analysis for review. City staff and engineering had reviewed the submittals and are requesting feedback from the Committee on deferment request of storm water pumping station and overall changes to the phasing plans. Mr. Jacobson noted that staff had no concerns with items 1, 2, 3, 5 as noted above from the value engineering analysis. Ms. Fischer presented a water surface elevation table that illustrated the Kettle 1 results for multiple scenarios of development which included off-site lands that drain to the Kettle 1. The table presented is included with the packet. Ms. Fischer demonstrated the theoretical analysis for multiple storm events showing that no adverse impact as compared to the pre-value engineering design which included the storm water pumping station pumping station to an infiltration area. Ms. Fischer did note that two (2) scenarios are below the theoretical two (2) foot of freeboard but other conditions may provide additional comfort for the City. These two (2) scenarios are also a worst case. The committee acknowledged no concerns based up on the analysis presented by Ms. Fischer but a series of conditions was noted that shall be included in a revised Developers Agreement where action will be taken at a later date, the conditions presented by Mr. Jacobson are as follows: 1. No development beyond Midthun property along CTH M (Block 1 Lot 1 and Block 2 Lot 1) and Whispering Coves phase 1 stage 1 that includes 26 lots within the Whispering Coves plat. 2. Developer shall accommodate force main construction to allow for connection to mobile pump. 3. Developer shall have a lease agreement with local (Dane County) pump supplier to allow mobilization to site for emergency pumping as directed by City Engineer or designee. 4. Developer shall pump when elevation is at the 100-year design storm water surface elevation (approximately 995 ft). Storm water shall be pumped to an elevation 2 feet above the bottom of the basin (approximately 992 ft). City Engineer shall be determine exact elevations based upon the approved engineering plans. 5. Letter of credit shall be provided for construction of future lift station, with a trigger event for the City to draw on the letter of credit. 6. Midthun and FDG need to acknowledge that the ponds on Midthun property shall be installed with phase 1 stage 1 of Whispering Coves development. 11. MOVED by Touchett, seconded by Ryan, to adjourn at 6:04pm. Motion carried 3-0. Note: These minutes were prepared by Theran Jacobson, Director of Public Works. These minutes are based on the notes of the recorder and are subject to change at a subsequent meeting.
