HARRISBURG AREA LAND USE PLAN <br />more or less than the area of land classified as undeveloped. Figure 3A displays <br />the land that may be considered available for future development, based on the <br />assumptions explained above. <br />Land Suitability <br />"Developability" refers to attributes other than constraints that make a given <br />area more or less attractive for future growth. For example, areas in close <br />proximity to sewer were scored better than others in terms of suitability. In <br />other words, areas close to existing sewer lines have a higher suitability scoring <br />than those that do not. Scoring decreases the further a site or area is from <br />existing sewer with the rationale that it will be more expensive to build new <br />sewer lines. <br />Factors were applied to six land uses categories corresponding with market <br />forecasts: Sing le- family /Townhome, Multi- family, Neighborhood Retail, Regional <br />Retail, Office and Industrial. Refer to Figures 3B -3G, Suitability Maps. <br />Single - Family /Townhome Suitability Factors <br />• Proximity to sewer collection line - Minimum 8" diameter line. <br />Proximity to sewer line using Euclidian distance. <br />• Proximity to water supply line - Minimum 8" diameter line. Proximity <br />to water line using Euclidian distance. <br />• Existing residential parcels within existing subdivision - These are <br />identified by the presence of parcels that have a land use description of <br />Condominium', 'Duplex, Triplex', Garden Apartment', Manufactured <br />Homes', 'Single Family Residence', or'Town House Apartment'. <br />• Proximity to existing neighborhood commercial - Based on proximity <br />to the nearest parcel with any type of commercial use based on tax data <br />using the cost surface grid representing the road network. <br />• Proximity to recreation sites - Proximity to the nearest existing park, <br />using the cost surface grid representing the road network. <br />• Proximity to elementary schools - Proximity to the nearest elementary <br />school up to a maximum distance of 2 miles, using the cost surface grid <br />representing the road network. After 2 miles, the suitability value will be <br />considered very low. <br />• Proximity to middle schools - Proximity to the nearest middle school <br />up to a maximum distance of 3 miles, using the cost surface grid <br />representing the road network. After 3 miles, the suitability value will be <br />considered very low. <br />Multi - Family Suitability Factors <br />• Proximity to sewer collection line - Minimum 8" diameter line. <br />Proximity to sewer line using Euclidian distance. <br />• Proximity to water supply line - Minimum 8" diameter line. Proximity <br />to water line using Euclidian distance. <br />• Proximity to major intersections - Proximity to an intersection of two <br />major thoroughfares or a major thoroughfare and a minor thoroughfare, <br />using the cost surface grid representing the road network. <br />PART II: EXISTING CONDITIONS <br />AUGUATaAW number 1 <br />G -1 Page 322 <br />
