44 Medium 1.2 Heavy 1.3 Precipitation Value of “S” Multiplier None to Light 1.0 Medium to Heavy 1.3 Residential Buildings City facilities the following formula and building blueprint dimensions will be used for estimating the quantity of debris from a demolished structures will be utilized in the event demolition of single-family residential buildings is required: L x W x S x 0.20 x VCM = cubic yards of debris (cy) 27 Where: L = Length of building in feet W = Width of building in feet S = Height of building expressed in stories 0.20 = Constant to account for the “air space” in the building 27 = Conversion factor from cubic feet to cubic yards VCM = Vegetative Cover Multiplier The VCM is a measure of the amount of debris within a subdivision or neighborhood. The descriptions and multipliers are described as: • Light (1.1 multiplier) includes new home developments where more ground is visible than trees. These areas will have sparse canopy cover. • Medium (1.3 multiplier) generally has a uniform pattern of open space and tree canopy cover. This is the most common description for vegetative cover. • Heavy (1.5 multiplier) is found in mature neighborhoods and woodlots where the ground or houses cannot be seen due to the tree canopy cover. The amount of personal property within an average flooded single-family home has been found to be 25-30 cy for homes without a basement and 45-50 cy for homes with a basement. Estimates of personal property volume assumes all residential properties without basements. Outbuildings In the event the City owned or outreach facilities that are a threat to the community require demolition, the following formula will be used to estimate the debris: L x W x H x 0.33 = cubic yards of debris 27 Where: L = length of building in feet W = width of building in feet H = height of building expressed in feet 0.33 and 27 are constants as noted in 2 above 2.3.4 Vegetation
