A site plan or a plot plan is a type of drawing used by architects, landscape architects, urban planners, and engineers which shows existing and proposed conditions for a given area, typically a parcel of land which is to be modified. Sites plan typically show buildings, roads, sidewalks and paths/trails, parking, drainage facilities, sanitary sewer lines, water lines, lighting, and landscaping and garden elements. Such a plan of a site is a "graphic representation of the arrangement of buildings, parking, drives, landscaping and any other structure that is part of a development project". A site plan is a "set of construction drawings that a builder or contractor uses to make improvements to a property. Counties can use the site plan to verify that development codes are being met and as a historical resource. Site plans are often prepared by a design consultant who must be either a licensed engineer, architect, landscape architect or land surveyor". Site plans include site analysis, building elements, and planning of various types including transportation and urban. An example of a site plan is the plan for Indianapolis by Alexander Ralston in 1821. The specific objects and relations shown are dependent on the purpose for creating the plot plan, but typically contain: retained and proposed buildings, landscape elements, above-ground features and obstructions, major infrastructure routes, and critical legal considerations such as property boundaries, setbacks, and rights of way… Site plan topics Site analysis Site analysis is an inventory completed as a preparatory step to site planning, a form of urban planning which involves research, analysis, and synthesis. It primarily deals with basic data as it relates to a specific site. The topic itself branches into the boundaries of architecture, landscape architecture, engineering, economics, and urban planning. Site analysis is an element in site planning and design. Kevin A. Lynch, an urban planner developed an eight cycle step process of site design, in which the second step is site analysis, the focus of this section. When analyzing a potential site for development, the status quo of the site should be analyzed and mapped. This includes but is not limited to: The location of the plot Topography, including information about slope, soils, hydrology, vegetation, orientation Existing buildings Roads and traffic Public facilities and utilities, including water, sewer, and power lines Related laws, regulation, codes, and policies By determining areas that are poor for development (such as floodplains or
