95
Four Ways Municipalities Can Control Development
1. Public Investment - transportation, parks, utility systems 2. Regulations - zoning, building codes, subdivision ordinances 3. Incentives and disincentives - preferential taxes, higher taxes on vacant property, zoning bonuses 4. Land Use Planning - comprehensive plan, capital improvement plan - Site Analysis, James LaGro
96
Three Sets of Issues Zoning Addresses
1. Permitted use of land and buildings - typically residential, commercial, industrial, or mixed-use 2. Intensity of the use - minimum lot size for homes, dwelling units per acre, number of stories allowed, etc. 3. Height, bulk, and other dimensional standards - percentage of the site covered by the building, set backs, lighting, signage, etc. - Site Analysis, James LaGro
97
Zoning Overlay Districts
These may impose additional development standards or may allow greater flexibility in the interpretation of the existing zoning. Example: Historic districts promote the preservation and restoration of buildings with historical significance. - Site Analysis, James LaGro
98
Subdivision Ordinances
Regulates the site development by defining street width, sidewalk requirements, shapes and size of lots, installation of public utilities, and specifications for lighting, trees, bus stops, and/or other amenities. - Site Analysis, James LaGro
99
Unified Development Codes
These attempt to eliminate the arbitrary distinction between regulations for subdivisions and all other forms of development. These standards apply to all development proposals, whether or not they require subdivision of land parcels. - Site Analysis, James LaGro
100
Site Plan and Development Review
A systematic assessment of the development proposal by the municipality. The proposal must meet the following basic standards: protect sensitive natural environments, prevent environmental harm, minimal impacts on surrounding properties, efficiency and convenience, proper relationship to public services (ex. fire and police), and adequate consideration to expansion options. - Site Analysis, James LaGro

106
Brownfield
A site that is contaminated with chemical waste. Previous laws (mainly the Superfund Program) accidentally discouraged the redevelopment of brownfields because they created significant legal and financial risks by assigning the liability of clean up costs to the new property owner, even if they were not responsible for the original pollution. - Site Analysis, James LaGro
107
Greyfield
A previously developed site that has minor and relatively easily mitigated environmental contamination. Example: strip malls. Developing these sites encourages urban infill and redevelopment rather than developing on the urban/suburban fringe. - Site Analysis, James LaGro
108
Deconstruction
The practice of reusing or recycling materials found in abandoned and vacant properties. Deconstructing buildings saves useful materials for reuse in new construction and rehabilitation projects and creates more jobs and business opportunities than demolition. - Site Planning and Design, Thomas Russ
109
Ideal Location for Open Space Relative to the Building
Located on the southern side of the building. Southern exposure is preferred over open space with northern exposure.  - Site Planning and Design, Thomas Russ
110
Best Combination of Shape and Orientation of a Building
An elongated building on an east-west axis because in winter the south side will receive three times as much solar radiation as on the east or west (for northern latitudes).  - Site Planning and Design, Thomas Russ
111
Key Elements of Site Analysis 
Location and relationship to the community (roadways, schools, shops, etc), topography, hydrology (including flood plain), vegetation, soil, zoning and regulation, infrastructure (utilities and transportation), and historical value.  - Site Planning
112
Does Proposed Use Effect the Site Analysis?
Yes, the context of the proposed use frames the scope and character of the site analysis. For example: a site with significant changes in elevation is difficult and more expensive for a commercial builder but it could be ideal for a resort of high-end residential developer. - Site Planning and Design, Thomas Russ
113
Elements the Initial Slope Analysis Identifies
1. Ranges or classes of slopes, and areas too steep to build 2. Potential locations for buildings 3. Possible routes for circulation 4. Drainage patterns - Site Planning and Design, Thomas Russ
114
Center for Integration of Natural Disaster Information
A resource for more detailed information on regional and local site hazards such as earthquakes, landslides, floods, ground water conditions, sinkholes and more. - Site Planning and Design, Thomas Russ
115
Liquefaction
When solid ground becomes "mushy" when soils are vibrated, associated with earthquakes. In certain cases, soil will lose all bear capacity, causing buildings to slip or sink and buried structures to rise to the surface. Typical, a soil with 15% or greater clay content is adequate protection. - Site Planning and Design, Thomas Russ
116
Phase I Environmental Site Assessment
Identifies if there is any environmental contamination. It is used to provide a standard that allows a property buyer or developer to meet the requirements established by the laws and courts to minimize the risk of environmental liability. There are ASTM standards for preforming this.  - Site Planning and Design, Thomas Russ
117
Traditional Residential Development Density
1 to 4 homes per acre. - Site Planning and Design, Thomas Russ
118
High Density Residential Development
6 to 12 homes or units per arce. - Site Planning and Design, Thomas Russ
119
Deep, Narrow Lots
Lots are range from 3,000 to 4,800 sq ft. Allowing for 6 to 8.5 lots per acre. Typically the garages are close to the front of the lot and there is minimal backyard privacy. - Site Planning and Design, Thomas Russ
120
Wide, Shallow Lots
Lots are typically 3,500 sq ft. Allowing for 6 to 7 lots per acre. These lots are not as desirable as deep, narrow lots because they have an increased cost and lack useful yard space. - Site Planning and Design, Thomas Russ
121
Alley Houses/Lots
Lots range from 3,300 to 4,500 sq ft. Allowing for 4 to 8 lots per acre. There are no driveways or garage doors . Parking is located in the back of the property, connected to a communal alley. This provides ideal utility corridors. - Site Planning and Design, Thomas Russ
122
Z-Lots
Zero lot line layout; houses are placed on or very near to one property line. Lots lines may job around the building. Houses are designed to increase light and maximize privacy to strategically locating windows and entrances. - Site Planning and Design, Thomas Russ
123
Steps of C.P.T.E.D.
1. Map the positive elements (schools, churches, long-standing bussinesses, etc.) 2. Map the areas of concern (abandoned buildings, high-crime areas, vacant lots, traffic patterns, etc.)  3. Use these two maps to work with the community or identifying and prioritizing the steps towards a safer community. - Site Planning and Design, Thomas Russ
124
Three Aspects of Defensible Space
1. Territory: drawing distinctions between spaces through methods such as changes in texture or elevation and barriers. 2. Access: controlling access by narrowing intersections, traffic calming, signs, etc. 3. Surveillance: seeing and being seen; windows and doors that face the street, porches, and points of congregation. - Site Planning and Design, Thomas Russ
125
Ways to Protect a Facility from Attack
Federal recommendations of some facilities call for a setback of 100' and a minimum of 15 acres. However, the same security can be achieved through incorporating changes in elevation and low barriers such as ponds, grading changes, berms, or strategically located site furniture. - Site Planning and Design, Thomas Russ
126
Durability Grades of Pavers or Bricks
NX: only interior, where wetting and freezing is not an issue MX: exterior, but without freezing SX: exterior, where freezing will occur - Site Planning and Design, Thomas Russ
127
Abrasion Resistance Grades of Pavers or Bricks
Type I: heavy traffic, such as driveways or commercial entrances Type II: medium traffic, such as outside a restaurant entrance Type III: residential or light duty patios - Site Planning and Design, Thomas Russ
