Current Planning Flashcards
Scales notes
Small-scale map = large area map with little detail.
Large-scale map = small area map with great detail.
U.S. Geological Survey = 1:24,000 scale of choice
1:24,000 means 1 inch = 2,000 linear feet
1:62,500 means 1 inch = 0.98 miles
1:500,000 means 1 inch = 7.89 miles
1:2,000,000 means 1 inche = 31.57 miles
Ex. 1:2,000,000…
2,000,000 inches/12 inches = 166,666 inches
166,666 inches/5,280 feet = 31.57 miles
What are the three main map types that allow projection of a spherical shape onto a flat surface?
Conic, Cylindrical, and Planar
Slope Notes
Contour = lines of equal elevation
Contour elevation = space between contours
Slope = vertical rise/horizontal run OR
change in “Y” coordinate/ change in “X” coordinate.
Rise/Run
Ex. Point A = 1 foot, Point B = 2 feet. Distance = 2 feet
1/2 = .50 X 100 = 50% slope
0-0.5% slope = no drainnge, not suited for development
0.5-1% slope = no probelms, idea for all types of development
1-3% slope = slight problems for large commerical areas, acceptable for residential development.
3-5% slope = major problems for commerical/industrial/large-scale residential development.
5-10% slope = suiteable only for specially designed development.
Floor Area Ratio notes
Ratio of the gross floor area of a building to its ground area.
Used to determine building density on a site (size of a building in relation to the size of its lot).
Floor area measured to the middle of the outside walls and includes the inside walls as part of the calculation (sometimes exclusdes uninhabitable spaces).
When did the first subdivision of land appear in the U.S.?
1660
This is the division of land into two or more parcels, sites, or lots for the purpose of transfer of ownership, development, or other forms of valuable interest.
Subdivision
This is a map of tract or parcel of land.
Plat
Process for lots to be subdivided further or added back together.
Replat
This process corrects errors adds additional information to a plat.
Amending Plat
This allows for a plat to be terminated prior to the selling of any lots.
Vacating Plat
To-scale mechancial drawing with precise topography and prescribed intervals showing the calculated location of all lots, streets, drainage, patters, facilities, and proposed dedications.
Preliminary Plat
The approved preliminary plat with all bearing, monuments, curves, and notations, together with all dedications, easements, and approvals.
Final Plat
Purpose of Subdivision Notes
1. Regulate subdivision development and implement a community’s planning policies.
- Implement plans for orderly growth/development within the City’s boundaries and extraterritorial jurisdiction.
- Ensure adequate provision for streets, alleys, parks, and other facilities.
- Protect future purchasers from inadequate police/fire protection.
- Ensure santiary conditions and other governmental services.
- Ensure ocmpliance with certians standards to officially register/record land.
Platting Process Notes
- Submit preliminary plat.
- Staff reviews against subdivision regulations.
- Plat reviewed by PC.
- Final plat prepared/submitted.
- Final plat repeats process until approved by PC.
This is the distance and area outside of the city limits where a city’s subdivision regulations apply. Typically specified under state law and usually increases with population size.
Extraterritorial Jurisdiction (ETJ)
This is an agreement between a property owner and a community to ensure that the final plat is built as shown on the drawings within a certtain time period. If not, the government may use the ______ to cover the cost of constructing the improvements. _______ is released once the improvements are in palce and have bene inspected by the local government.
Performance Bond
A type of exaction - a gift of land for public purposes (raods, parks, and utilities).
Dedication
A type of exaction - a fee charged for off-site infrastructure needed to provide service to a development (water/sewer main).
Imapact Fee
A voluntary contract between a local jurisdiction and a property owner detailing the obligations of both parties and specifying the standards and conditions that will govern development of the property.
Voluntary, but binding once made.
Provides assurances to the developer that the regulations that apply to the project will not change during the term of the agreement.
City/County may require conditions to mitigate project impacts or info on phasing/timing of public improvements.
Development Agreement
This is an extension of development benefits beyond those normally offered ine xchange for enhancements (affordable housing, cluster housing, open space preservation).
Could be assistance with infrastructure, impact fees waived, or abilty to construct at higher densities.
