<br />Appendix C. Site Inventory and Analysis <br /> <br />A thorough site inventory and analysis is the cornerstone of good site design. The inventory and analysis can help ensure that dnN/opment is <br />compatible with its surroundings and that it is sensitive to the natural features and functions of the site. <br />The documentation and recommendations that result from an inventory and analysis provide the basis for deciding the nature, type, density, and <br />configuration of the proposed development. Since each site is different from most others, the inventory must be broad enough to consider as many <br />'variables as possible (e.g., the presence of slopes, existing watercourses, and access roads). The inventory must also take into account the purpose of <br />the development (e.g., high-density multifamily housing or single-family housing). <br />After the data is collected, it is typically displayed on a base map with an overlay for each variable. Viewed together, the composite map <br />clearly depicts the site's assets and liabilities. There are a variety of methods for using maps to identify the suitability of a site for development. <br />One such method is to map each component of the inventory according to the way it either enhances or constrains development opportunities. <br />Combining each of these will produce a suitability map. <br /> <br />Sample Site I11ventory and AnaltjS1S <br /> <br />Existing Land Uses <br />1. Describe and map the site location in a regional <br />context <br />2. For all property within a 1/ 4-mile radius of the site <br />describe and map: <br />a. existing zoning <br />b. existing land use <br />c. pending rezonings <br />d. subdivision or development plans under review <br />e. existing utility or other easements or <br />restrictions <br /> <br />Topography <br />Describe and map the topographic characteristics of the site <br />including: <br />a. slopes (specify contour interval) <br />b. peaks and ridges <br />c. rock outcroppings <br />d. other significant topographic features <br /> <br />Hydrology <br />1. Identify and map: <br />a. all off-site \vatersheds that affect or are affected by the <br />site <br />b. significant off-site natural and man-made features <br />located within the watersheds mapped above that may <br />affect of be affected by the site. <br />2. Indicate the area in acres for those upstream, off-site <br />watersheds with IOO-year discharges greater than 500 cubic <br />feet per second (cfs). <br /> <br />On-Site Drainage <br />1. Identify and map: <br />a. drainage patterns <br />b. sv,rales <br />c. existing inlets, culverts, or drains <br />d. areas of erosion or siltation <br />2. Identify existing well or well sites within 100 feet of the site <br />and list O\'I.'ners <br /> <br />Floodplains <br />Identify and map on development site: <br />a. flood way boundary <br />b. lOO-year floodplain elevations and boundaries <br />c. wetlands location <br />d. seeps, springs, and wells <br />e. flood control or diversion structure <br /> <br />Soils <br />Map or describe: <br />a. depth <br />b. permeability <br />c. stability <br />d. shrink/swell characteristics <br /> <br />Vegetation <br />Inventory, describe, and map: <br />a. existing vegetation on the site <br />i. tree cover (types and species) <br />ii. understory <br />iii. ground cover <br />b. designated threatened and endangered species <br />c. other wildlife habitat <br /> <br />Viewsheds <br />Describe and map: <br />a. unique off-site views and vistas that may be impaired <br />by development of the site <br />b. those areas of high, medium, and low visibility of the site <br />as determined from off-site locations surrounding the site <br />c. the criteria used in determining high, medium, and low <br />areas of visibility <br />Traffic <br />1. Map the existing and proposed off-site streets onto which the <br />site will have access to their intersection with a major route <br />2. For those streets identified, provide the following information: <br />a. existing rights-of-way <br />b. rights-of-way for all proposed off-site roads in the <br />immediate vicinity <br />c. existing and proposed pedestrian and bicycle ways <br />Sewers <br />Map the location of the existing public sewers in relation to <br />the project site <br />Schools <br />1. Map and identify all existing and proposed schools within <br />a 1.5-mile radius of the site <br />2. Describe the location of all schools that will serve the site, <br />if not within the l.5-mile radius. <br />Recreational Facilities <br />1. Describe and map each of the following that are within one <br />mile of the site: <br />a. trails <br />b. existing and proposed greenways <br />c. parks and other recreation areas <br />2. State the size (in acres) and type (e.g., active or passive <br />recreation) of the areas identified <br /> <br />Cultural Resources <br />1. Describe and map cultural and historic resources on the site <br />2. Provide a letter from the State Historic Preservation Office <br />or a qualified archaeologist stating: <br />a. the probability of archaeologic resources being <br />discovered on the site <br />b. the agency's or individual's recommendation as to <br />whether an archaeologic survey is needed <br /> <br />53 <br />
