Intro & Data
Lesson 12 Site Analysis & Codes/Regulations
| Term | Definition |
|---|---|
| Small Scale | May displays a large land area with very little detail |
| Large Scale | Map shows a limited land area in great detail |
| Common scale for US Geologic Survey | 1: 24,000 scale |
| Contour Lines | Lines of elevation |
| Contour Interval | The distance between contour lines |
| Slope | Calculated by the change in elevation divided by the horizontal distance |
| Floor Area Ratio | Ratio of the amount of the floor area on a parcel to the amount of land area of the parcel Calculations are used to determine floor space in relation to given lot size Primarily to determine building density on a site |
| Site Planning | Landscape architecture plan and engineering drawing of proposed improvements to a given lot |
| Code | Composed of rules and regulations |
| Ordinance | Refers to specifically to municipal law |
| Law | Is more general and occurs at any scale of government |
| Building Code | Based on health and safety standards and control design, construction, and materials used in construction |
| Subdivision Regulations | Control the manner in which blocks of land over a certain size many be converted into building lots |
| Critique of FAR | How the building is acting on the lot (e.g. setbacks) |
| FAR Question: If a 2.5-acre lot has has FAR of 6, how many stories can be built, if 60% of the site will be required for onsite storm water treatment, parking, sidewalks and landscaping? | 6 X 2.5 = 15 Note: the 60% doesn't matter |
| Variance | Granted because of the specific physical characteristics of a particular property May alter the allowable use of the parcel Board of Zoning Appeals (BZA) deals with site-specific modifications |
| Conditional Use Permit | Allows land uses in zone where the use isn't currently allowed "Special use permit" |
| Overlay Zone | Allows a community's functional concerns to out across existing zoning designations Establishes additional standards for properties, in addition to underlying zoning districts |
| Floating Zone | Districts that are described in a zoning ordinance but have no necessarily been including on the zoning map |
| Planning Unit Development (PUD) | Floating zone intended to create a mix of uses, density, and infrastructure standards, to allow flexibility in the development standards for specific uses on the subject site |
| Performance Zoning | Performance standards regulate development by setting desired goals Provides flexibility Tend NOT to include restricting specific uses on a property, but permits that meet a specific set of standards |
| Nonconforming Use | Is a use of property that was allowed under the zoning regulations at the time the use was established but which, because of subsequent changes in those regulations, is no longer a permitted use |
| Form-Based Code | Design-based regulations; not guidelines Composed of building form standards and public space standards mapped to a regulating plan |
| Transect-Based Planning | Subcategory of form based code Zoning document based on environmental analysis |
| Rural to Urban Transect | Based on density |
| Zone of the Transect | Natural Zone Rural Zone Sub-Urban Zone General Urban Zone Urban Center Zone Urban Code Zone Special District |
