At this point in the process, we are not able to certify the drainage Improvements tor -the site, as there are several items still incomplete at this time. It appears that the grading around the building has been completed satisfactorily, however, survey points were not provided to verify this. Survey points were provided in the detention pond area, but not all facilities appear to have been constructed. The following is a punch list of Items for completion: • Survey finished floor elevations, ground adjacent to building and away from the building to prove that there is positive drainage away from the structure. • Survey of the field inlets and storm drain pipe, where possible, to verify substantial conformance with design. • Construction of water quality outlet structure for the detention pond (per details on sheets 4 and 9 of the construction drawings). • Raise detention pond berm to elevation 4937.40 to provide adequate freeboard (existing is 4936.94 near the church sign). When these Items are completed, Ayres Associates will be happy to complete a proper drainage certification letter for the site.
