Case BLADHOLM BROS. - CUP FOR DEMOLITION LANDFILL By: ~erland Otto, Acting Zoning Administrator The proposed demolition landfill site is situated on a 13.3 acre site all of which is zoned I-1 (Industrial). Our review of the pro- posal raises several concerns. Among the most significant are whether the proposed use is consistent with the city's comprehen- sive plan as well as operational concerns. Consistency with Comprehensive Plans The City's comprehensive plan indicates that sewer and water ultimately would be extended through the site (Exhibits A and B). The Highway 10 Corridor Study also proposed a frontage road through the site. The construction costs of locating this infrastructure through a demolition landfill would increase significantly due to obstructions, additional excavation and potential settlement problems. Further, nearly half of the proposed landfill site has been recommended to be acquired for airport property. Should the city proceed with acquisition, purchase of a demolition landfill site would not be in the City's best interest. As the CoMmission is aware, the City has only a finite amount of commercial and industrial property with Highway 10 frontage. These properties would normally be considered prime for the type of development which the City wishes to encourage. It appears inconsistent with city plans to take existing developable land out of this pool and convert it to landfill status. Operational Concerns The proposed filling operation indicates a vertical use of airspace of approximately seven feet. This is an inefficient use of space relative to the land area involved since it uses a large surface area for a relatively small volume of demolition. Production figures are estimated with a potential for a significant increase dependent on whether or not the applicant expands its production line. However, at current waste production rates, the fill would have a capacity to accomodate nearly 85 years of waste production. Pollution/contamination of ground water should be of minimal concern assuming concrete and reinforcing steel are the only components. Cells are sufficiently above the water table. wind and water erosion as well as dust control is of concern. The applicant needs to provide more specifics on cell closure and re- establishment of vegetative cover.
