REGULAR MEETING: Application 23-04WF - Proposal by PDS Engineering & Construction Inc. Collier to construct a building addition and related parking improvements within both an upland review area and flood hazard zone on Lot 3A, Block 81, 400 Christian Lane. Barton Bovee, P.E., H. E. Cole & Son, was present for the Applicant. He displayed a revised print and reviewed the proposal. The proposed plan will construction an addition to the rear of the existing building. The addition will be 7,250 square foot. Majority of the building is to be constructed within an area that is currently developed as a gravel roadway. The proposed plan also includes the expansion of the parking lot to meet zoning requirements. The addition building will have bathrooms that are to be connected to the existing sanitary main located along the southern property boundary. Water service will be provided through internal connections to the existing building. Page 1 of 3 The site does contain a 100-yr Floodplain elevation of 45.0 through the site from the potential flooding of the Willow Brook to the north; as well as the associated Floodway. The building addition will be constructed outside the Floodplain, but will have the Floodplain extended to the proposed loading dock area, similar to the existing building’s configuration. The site will have a minor cut for the loading dock and the proposed parking lot is to closely match the existing grade. Detention for the site will be provided in the form of retention basin for storage of runoff from the roof leaders and adjacent parking lot. Stormwater will flow over the parking through to the stone trench and then into the retention system. The basin is anticipated to infiltrate and not outlet control structure is provided as the basin is located within the Floodway. The basin is only sized to decrease the peak flow from the proposed development and is not included in any floodplain filling compensation. The system is also sized to self- contain the Water Quality Volume. Mr. Bovee added that the Applicant, per Staff’s request, will be removing all but one of the structures located within the floodway. The remaining, more permanent structure, will be enhanced to allow floodwaters to move through, and relieve, hydrostatic pressures created during a major storm event. Chairman Nieman asked the Commissioners if they had further questions. Hearing none, asked if there was a motion. Commissioner Pavano made a motion to approve Application 23-04WF conditioned upon the applicant installing AbTech Smart Sponge Filters (or an equivalent approved by Staff) in all existing and new catch basins, and the Standard Conditions of approval. The motion was seconded by Commissioner Russo. The motion was unanimously approved. Other Business to Come Properly Before the Commission 1) Application 20-07WF- Proposal by 550-554 Berlin Turnpike Associates, LLC, to construct a Multi-Family Development and associated appurtenances within an upland review area, floodway and floodplain on Lot 13, Block 83, #522 Berlin Turnpike. Request for Permit Modifications. Barton Bovee, P.E., H. E. Cole & Son, was present for the Applicant. He displayed a revised print and reviewed the proposed permit modifications. The initial Wetlands Approval was in 2020. As part of the Planning and Zoning approval process, the Applicant was advised to add a small rotary between buildings #2 and #3 which causes a slight impact to the previously requested disturbance in the wetlands upland review area. This change, including the reduction of some parking in this area, will have a slight decrease in the area disturbed within the upland review area. The notes on the revised plan describe the FEMA flood hazard zone impacts and the 50’ upland review impacts. Page 2 of 3 Chairman Nieman asked the Commissioners if they had further questions.
