MEASUREMENTS AGAINST TECHNICAL TEST REQUIREMENTS Coverage Test SEH utilized data in a GIS (Geographic Information Systems) database, available through Sherburne County and the City of Elk River, to obtain individual parcel information. The GIS database contains both graphic information (parcel shapes) and numerical data based on county tax records. This information was used by SEH for the purposes of this assessment. The total square foot area of each property parcel was obtained ftom county records (GIS) and general site verification. The total extent of site improvements on each property parcel was digitized ftom recent aerial photography. The total square footage of site improvements was then digitally measured and confirmed by general site verification. The total percentage of coverage of each property parcel was computed to determine if the 15% requirement was met. Refer to attached maps: Occupied Surfaces map and Percent Occupied Surfaces map. The total area of all qualifYing property parcels was compared to the total area of all parcels to determine if the 70% requirement was met. The area occupied by public rights-of-way has not been considered in the coverage test calculations. All of the public rights-of-way are improved. If all of the public rights-of-way were treated as a parcel for the purpose of coverage test calculations, the 70% requirement of the coverage test would still be met. Condition of Building Test Replacement Cost - the cost of constructing a new structure of the same size and type on site: R. S. Means Square Foot Costs (2003) was used as the industry standard for base cost calculations. R. S. Means is a nationally published reference tool for construction cost data. The book is updated yearly and establishes a "national average" for materials and labor prices for all types ofbuilding construction. The base costs derived ftom R. S. Means were reviewed, and modified if applicable, against our professional judgement and experience. A base cost was calculated by first establishing building type, building construction type, and construction quality level (residential construction) to obtain the appropriate Means cost per square foot. This cost was multiplied times the building square footage to obtain the total replacement cost for an individual building. Additionally, to account for regional/local pricing, a cost factor was added to the total cost according to R.S. Means tables. Using R. S. Means, consideration is made for building occupancy, building size, and construction type; therefore, the cost per square foot used to construct a new structure will vary accordingly. 7
