3 Basic Map Projections
Conic, Cylndrical, Planar
Contour Lines
Lines of equal elevation.
The closer the lines are, the steeper the elevation
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
