6 AOP Current Planning Flashcards
Map Scale
Small scale map displays large land area with little detail
Large scale map shows limited land area in great detail
COMMON SCALES:
USGS - uses 1:24,000 aka 1 inch represents 2000 LF
1:62,500 aka 1 inch represents .98 mi
1:500,000 aka 1 inch equals 7.89 mi
1:2,000,000 aka 1 inch equals 31.57
slope guidelines
0-.5%: No drainage, not suited for development
.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
convert map scales
Map scale in inches that you want to convert to linear miles:
Divide map scale by 12 (since there’s 12 inches in a foot)
Then divide that number by 5280 (because 5280 feet in a mile)
Map scale in miles that you watn to convert to inches
Multiply the map scale by 5280
Multiply that number by 12
3 types of map projection
Conic: Cone placed over a globe but cuts through the surface.
Cylindrical: Cone placed over a globe, meet along a latitude line.
Planar: Plane is placed over a globe - plane can touch the globe at the pole, the equator, or another line
Site Plan Review
Scaled drawings that show detailed layout of a development proposal
Include: lot lines, roads, existing and proposed building footprints, major landscape features, utility rights-of-way.
Carried out to guarantee compliance during the zoning permitting process to determine if a variance is necessary.
Floor Area Ratio
Ratio of the gross floor area of a building to its ground area. 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
Subdivision
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. This definition varies from state to state and may include minimum acreage requirements.
Plat
Map of a tract or parcel of land.
Replat
Allows for lots to be subdivided further or added back together
Amending plat
Corrects errors or adds additional information to a plat.
Vacating plat
Allows for a plat to be terminated prior to the selling of any lots.
Preliminary plat
To-scale mechanical drawing with precise topography and prescribed intervals showing the calculated location of all lots, streets, drainage patterns, facilities, and proposed dedications.
Final plat
The approved preliminary plat with all bearing, monuments, curves, and notations together with all dedications, easement, and approvals.
Purposes behind subdivision regulations are:
To regulate subdivision development and implement planning policies
To implement plans for orderly growth and development within the city’s boundaries and extraterritorial jurisdiction (ETJ);
To ensure adequate provision for streets, alleys, parks, and other facilities indispensable to the community;
To protect future purchasers from inadequate police and fire protection;
To ensure sanitary conditions and other governmental services;
To require compliance with certain standards;
To officially register land.
To subdivide land, a property owner must work with the city or county to develop a plat. To plat a property, the following steps must be taken:
The applicant submits a preliminary plat;
A preliminary plat is reviewed by staff for compliance with subdivision regulations;
Plat is then reviewed by the planning commission;
Once the preliminary plat is approved by the planning commission, the property owner prepares the final plat;
Final plat then repeats the process above until it is approved by the planning commission.
Development agreement
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. Although the agreements are voluntary, once made they are binding on the parties and their successors.
Performance bonds
A performance bond is an agreement between the property owner and the community to ensure that the final plat is built as shown on the drawings within a certain time period. If the developer fails to meet the requirements, the government may use the bond to cover the cost of constructing the improvements
Dedications
Dedications are gifts of land for public purposes, such as roads, parks, and utilities
Impact fees
. Impact fees are typically charged for off-site infrastructure needed to provide service to a development, such as a water or a sewer main.
Exactions
Property owner / developer required to provide these in the form of dedication of the land or payment in-lieu of dedication.
Purposes of zoning
Protect and maintain property values;
Promote public health and safety;
Protect the environment;
Promote the aesthetic of a community;
Manage traffic;
Manage density;
Limit housing size and type, or encourage a variety of housing types;
Attract businesses and industries.
