No. 2110-028 Date 1/11/2022 By: ALD Chk:. ALD MASTER DRAINAGE PLAN AND CALCULATIONS SECTION 1 PROJECT NARRATIVE Keeler -Webb Associates is acting as agent surveyor/engineer for Mr. David K1ain who is the owner/developer/General Contractor of the above project. Park Place Centre was master planned and built in 1999 and has two remaining building sites in the Commercial Office HPR. Currently, the building pad sites are vacant with all utilities available and all other site improvements in place (i.e., curb cut, signage, site lighting, parking, mailboxes, trash enclosure, etc.). The newly proposed buildings will be constructed by db Klain Construction. Building 4 is a 2-story masonry office building at 712 Adams Street with a 4,382 sq.ft. footprint and Building 6 is a 2-story masonry office building at 708 Adams Street with a 5,255 sq.ft. on the final phase of Block 2, Lot 2, containing 0.835± Acre. There will likely be multiple tenants in each of the office buildings. Other site improvements will include connection to all utilities, installation of ADA ramps and sidewalk in front of the buildings and a new sidewalk between the buildings connecting to the Adams Street sidewalk, mechanical equipment, and concrete patio adjacent to the breakrooms in each building for employees. Parking for employees, and customers will be provided in the spaces shown in the shared parking for all of the buildings in Park Place Center. The building elevations have been designed to match the architectural design elements of a modern federalist theme per the Park Place Centre Master plan approved by the Plan Commission in 1999. Storm water will be collected via gutters and downspouts and directed to a new SWQU structure which is the on -site BMP. Stormwater will be discharged towards Adams Street via an existing private storm sewer and directed to the off -site BMP which is the regional detention pond for Carmel Science and Technology Park.
