There is one existing commercial building on the site that will remain. The parking for the proposed buildings will be asphalt and concrete pavement with curb and gutter. Parking that will be added behind the existing building will be asphalt pavement without curb and gutter. Underground stormwater collection will be used to route stormwater to the proposed detention pond. The detention pond has been sized to accommodate runoff from the entire site, existing and proposed. Calculations for the detention pond are attached. 4 PERMANENT POOL DETENTION PONDS DESIGN OF POND Diana Gailop - Ehringhaus St. Property 10 Yr, 24 Hr Storm Robey Associates Engineering P. 0.
