site analysis: first step in site analysis is gathering physical data What are they?
(surveying): boundary lines, north and scale, benchmarks, easements, roads and ROW, bldgs positions, utilities, bodies of water, natural areas to preserve, topography, etc.
Site design determinants:
o areas of steep to moderate slope o macro and micro climate conditions o solar energy considerations o potential flood zones o possible road access o natural areas to preserve o wildlife habitat o soil conditions o geological considerations o exceptional views o adjacent land uses o noise sources
Important environmental considerations:
o air movement
o sun and shadow patterns
o reflections
Urban contextual analysis
o Building typologies and hierarchy o Regional character o City form o Building scale o Building transition o Views
Environmental site analysis
o Slope o Soil patterns o Vegetation o Wildlife o Geology o Surface and subsurface water o Climate
The purpose of site analysis are to?
Gather data for preliminary planning, evaluate the site for compatibility with the proposed project or use, recognize concerns requiring additional study, and form an understanding of the administrative requirements of the project such as required permits and approvals.
Site analyses are conducted in two steps:
a proposal phase to facilitate winning the work and a post contract phase.
Site characterization is
A more detail investigation that is usually undertaken after some degree of preliminary site planning. Generally includes a geotechnical analysis of subsurface conditions such as depth to bedrock, depth to groundwater, seasonal high water table, and specific soil test.
First consideration of the site analysis
Is to locate the site. It refers to the project relationship with the community, concerning about visibility, access and traffic.
Preliminary site assessments
Are based on existing sources of information or first-hand observation.
Topography
May dictate the purposes for which the site may be used. The nature of the material making up the slope is also important.
Slope analysis
Is done to identify the areas of steep slope and the possible location for buildings sites and access; is usually a graphic representation of slope shown in classes or ranges.
Site analysis is the foundation of the plan
It will provide the framework from with the planning and design is developed.
Aerial photogrammetry:
Provides an accurate mapping of topographic and physiographic features using low-level and aerial photography. The topography is interpolated from limited topographic data collected on the ground. May be less expensive than traditional field topographic methods. Collected during winter months.
Historical aerial photography:
Inexpensive and valuable source of information. Enlarged photos reveal site features not clearly visible at ground level such as drainage patterns, sinkholes and remains of historic structures. Helpful in presenting site analysis data to those who may not be comfortable reading plans.
Soil descriptions include:
Info on slope, depth to bedrock, soil texture, erodibility, rock and drainage characteristics.
Land development regulations
Typically include requirements for local street design, open space, lighting, subdivision standards, minimum landscaping, and similar development parameters.
Local officials may have the authority to ___ or ___ iof the land development ordinance on a case by case basis.
wave or modify provisions
Zoning regulations are
enforceable and cannot be waved without justification and a formal hearing process. May contain design criteria such as parking configuration, lot sizes, setbacks, road width, road profile restrictions, and sign requirements.
Zoning dictates the following 4
permitted uses, density, minimum lot sizes and open space.
Historical value:
sources of information include local and state historical agencies and societies, local government records, maps and libraries. Some local historic values are not documented and are unwritten and informal.
Offsite considerations:
traffic issues, local flood, storm water concerns, infrastructure issues.
The phase I ESA
Is designed to be an overview of a site involves no collection or testing of samples and is limited to information already available through public sources, interviews or firsthand observation.
o Sources used to determine the history of the site and surrounding areas: aerial photographs, local historic maps, and historic USGS topo maps, fire insurance maps, tax files, local records, interviews, fifty-year chain of tittle.
Site Analysis and assessment: Determining if you have selected the best site for your project.
o The most environmentally sound development is one that disturbs as little as possible. Building projects also require connections to mass transit, vehicular infrastructure, and utility and telecommunications networks.
o Building characteristics, orientation and placement should be considered in relation to the site so that proper drainage system, circulation patterns, landscape design, and other site-development features can be determined.
