BW's rainwater management policy and guidelines are reproduced below. To effectuate those guidelines, BW retains the firm Neff and Associates (http://pcvcs.com/Neff/projects/educational-municipal/), which specializes in civil engineering and landscape architecture to annually review BW's bioswales and attendant issues (e.g., soil erosion, runoff blockages, debris collection, and etc.). The firm then supplies a checklist of upkeep and maintenance issues to be addressed by Baldwin Wallace University's Building and Grounds Department and files their reports with the City of Berea's Engineering Department. Please see the attached file for BW's 2018 insprection report including diagrams of the bioswales and water remediation sites, photographs, and Storm Water Detention/Retention Structures – Annual Inspection Form for the follwing sites on campus: (1) Adalbert Street Parking Lot (2) Beech Street Parking Lot (3) Church Street Parking Lot (4) CIG (Center for Innovation and Growth) Parking Lot (5) Durst Welcome Center (6) E. Bridge Street Parking Lot (7) MCS (Math and Computer Science) Parking Lot Please note that the large Bonds Parking Lot outside of the main administration building has also been fully updated with bioswales as well. Photographs have been included in the attachment. However, they were too new to receive inspection in 2018 and will await inspection next year. --------------------------------------------------- SECTION 334100 – STORM WATER PART 1: GENERAL 1.1 Any deviances from the following instructions must be approved during design by Baldwin Wallace University Facilities Management Personnel. 1.2 Performance Requirements All new work, taking place within the city limits of Berea or in watersheds feeding the City of Berea, shall be in accordance with the Storm Water Ordinances of the City of Berea and Ohio EPA.
