3 Basic Map Projections
Conic, Cylindrical, Planar
Slope
Change in elevation divided by horizontal distance
Slope guidelines
0-0.5% = no drainage, not suited for development; 0.5-1% = no problems, ideal for all types of development; 1-3% = slight problems for large commercial areas; acceptable for residential; 3-5% = major problems for commercial/industrial/large scale residential; 5-10% = suitable only for specially designed development.
What type of slope is good for all developments?
0.5 to 1% slope. No problems, ideal for all developments.
Floor Area Ratio
ratio of the gross floor area of a building to its ground area
For instance, if a 20,000-square-feet parcel has a FAR limit of 0.5, then the floor area of the building or house on the site may not exceed 10,000 square feet. This FAR could be achieved with either a single-story, 10,000-square-feet structure or a 2-story structure with 5,000-square-feet per floor.
Site Planning
Site Planning includes a range of factors including site selection, transportation, earthwork and utilities, and design of the site. Individual land uses have different site planning criteria
What is the difference between a preliminary plat and final plat?
A final plat is a more precise drawing, done by a surveyor - much more regulatory.
FAR is the ration of what to what?
Ratio of amount of floor space on a parcel to the amount of land area of the parcel.
FAR = 3 can mean a 3 story building covers the parcel of land completely.
FAR = 3 can also mean 6 story building on half of the building site. 6 x .5 / 1 = 3
What is the key difference between a variance and a special use permit?
A special use permit, aka conditional use permit, is granted to allow land uses in zones where the use isn’t allowed.
A variance is granted because of the specific conditions of the property.
How is an overlay zone different from a floating zone?
An overlay zone applies rules to a specific area.
A floating zone is not located on a zoning map but is a defined type of zone that can be applied in a proposed location. Like a PUD.
What is the difference between form-based codes and design guidelines?
Form based codes are regulatory; guidelines often lack the ability to regulate - they are simply guidelines
How is land use dealt with in a form-based code?
The regulation of landuse is included in form-based code but it is a secondary concern after the regulating of form
How is a urban to rural transcet used in form-based coding?
If a form-based code is transect-based, it will have 6 zones that vary along an urban-to-rural continuum (or transect).
Rules will be applied according to the urban-to-rural-character of the zone.
