Russ Chapter 3 Site Planning & Design Handbook
| Question | Answer |
|---|---|
| Site Analysis | The process of gathering and evaluating data about a site’s physical, ecological, and administrative characteristics to determine its suitability for a proposed project. It identifies issues, opportunities, and constraints before design begins. |
| Site Characterization | A detailed investigation following initial analysis, including subsurface exploration (depth to bedrock, groundwater, soil tests) as guided by ASTM D-420 standards. |
| Location | Refers not only to a site’s geographic position but also to its relationship with the surrounding community—visibility, access, traffic, and connectivity are central. |
| Aerial Photogrammetry | Mapping topographic and physical site features using aerial photographs, meeting National Map Accuracy Standards. Provides less costly topographic data than ground surveys. |
| Historical Aerial Photography | Past aerial images used to identify previous land uses, natural features, or alterations. Helpful for understanding site evolution and hidden features. |
| USDA Soil Survey | A comprehensive database of soil characteristics, including texture, slope, erodibility, and depth to bedrock. Used to evaluate suitability for development and identify potential soil hazards. |
| Expansive Soils | Soils that swell when wet and shrink when dry, leading to foundation or pavement cracking. |
| Liquefaction | Loss of soil strength during vibration (e.g., earthquake), causing the ground to behave like a liquid—dangerous for structures. |
| Hydrology | Study of surface and subsurface water movement across a site. Includes drainage patterns, water tables, wetlands, riparian zones, and floodplains, all of which affect development suitability. |
| TMDL (Total Maximum Daily Load) | The regulatory limit for pollutants that a waterbody can receive under the Clean Water Act; affects stormwater design. |
| Local Records & History | Information from local government about zoning, land use, and historical development that influences design constraints and opportunities. |
| Zoning | Local regulation dictating permissible land uses, densities, and setbacks. Determines what can be built and where. |
| Land Development Regulations | Local standards for site elements like streets, landscaping, and lighting that shape the project’s layout and compliance. |
| Utility Mapping | Identification of existing water, sewer, electric, and other service networks; crucial for planning new connections or relocations. |
| Assessing “Fit” | Evaluating how well a proposed project aligns with the site’s character, community values, and physical/environmental constraints. |
| Program Requirements | Functional and spatial needs of a project that drive site design decisions (e.g., parking, access, circulation, building placement). |
| ADA (Americans with Disabilities Act) | Federal law requiring accessibility in site and building design. ADAAG guidelines specify standards for slopes, ramps, walkways, and parking. |
| Community Standards and Expectations | Informal social or aesthetic norms influencing how development is perceived locally—includes materials, styles, and landscape character. |
| Environmental Concerns | Potential contamination or site conditions stemming from past industrial or commercial use; part of environmental due diligence. |
| Environmental Site Assessment (ESA) | Systematic process for identifying potential or existing environmental contamination on a property, typically following ASTM E-1527 guidelines. |
| Phase I Environmental Site Assessment | A non-invasive study reviewing records, historical data, and on-site conditions to identify Recognized Environmental Conditions (RECs). |
| Brownfields | Abandoned or underused properties with actual or perceived contamination. Redevelopment requires mitigation or remediation strategies. |
