constructed of materials other than metal on at least 50% of the exposed wall when the building is adjacent to a street. A variance from this requirement will be necessary. 10) Drainage: A drainage plan was not submitted nor has a topographic map been provided which would enable the drainage to be analyzed. However, during a site visit the following observations were made concerning the drainage: a) The Northeast half of the property generally drains toward the northeast comer of the site where it enters a drainage swale which occupies the southernmost 20 to 25 feet of the adjacent parcel to the north. b) The above ponding area is connected to city' street and county road ditchlines, however, it appears this system of ditches does not have an outlet since they run uphill to a large natural ponding area located just north of Basalt Street and Industry Avenue. c) The remainder of the property drains to the west boundary of the site and then north to the above mentioned pond and ditch system. Based upon the above observations, I would have to conclude that during a four inch storm event, which is the basis for city design, the present facility will discharge storm water onto the adjacent property and into public right-of-way where it will remain until it percolates away. I would recommend that the lawn area on the northeast comer of the site be regraded to form a small detention pond. This pond might be approximately 3 feet deep with side slopes of 1:5 so that is could be easily mowed to maintain the attractive appearance of the existing site. Although the storage capacity of this pond would not accommodate the design runoff from the site, it would more than offset the increase in runoff from the expansion and be an overall improvement to the area drainage. 11) Curbing: At the present time, no curbing is provided on the site. Concrete curbing is a City Code requirement. 12) Hard Surfaced Drive Areas: At the present time, all drive areas are not hard surfaced. Hard surfaced driveways are City Code requirement. The following is a list of items that were not submitted as required by City Code: a) Property survey certified by a registered land surveyor. b) Topographic of the map property. c) A building design plan certified by a re~stered architect. d) A site drainage plan. e) Location of exterior refuse containers. f) Location of signage.
