• Map Types
• 2. Scale Considerations
• Contour Interval
• Map Purpose
• 3. Application Examples

1. TYPES of PLANNING MAPS

• 1.1. CADASTRAL Property Maps
• Tax Assessment
• 12,500 to 11,200 for suburban areas
• 1500 for highly developed urban areas
• Major OTHER USES
• Scales will Vary
• Land acquisition Land/Building
  evaluation
• Building conditions Land uses
• Land value Land
  Subdivision
• Local community planning

1.2. GEODETIC SURVEY MAPS

• (Map types, continued)
• New or Existing Survey Markers
• aka Bench Marks (BM)
• Also other Geodetic Control Points
• Spores Survey Control
• based locations of original, lost monuments
• Horizontal and / or Vertical Accuracy
• Starting Point of other Land Surveys
• typical scales 125 to 1500 range

4
1.3. HYDROLOGIC and SOIL MAPS

• (Map types, continued)
• Drainage patterns
• Topography/Physiography Maps
• For Site Planning
• 11000 scale
• also used to show
• Sewer and water systems plans
• Cut and fill areas (contour changes)
• Conservation areas (wetlands)

5
(Map types, cont.)

• 1.4. LAND DEVELOPMENT MAPS
• Zoning and Other Development Controls
• Land Use Building Footprints
• Redevelopment Areas
• 1.5. TRANSPORT INFRASTRUCTURE MAPS
• Road and Road Structures of all types
• Other Transportation Facilities
• Other Major UTILITIES
• Pipes (gas, water, other)
• Wires (electric)

6
2. SCALE Considerations

• Scales Vary by PURPOSE
• There is no perfect Map for all Purposes
• Other Major Variables include
• Size of Area that you want to show
• Size of Paper that you want to show it on
• Minimum Details required
• Contour Intervals Scale
• Larger Scale allows Smaller Intervals
• Smaller Scale requires Larger Intervals
• Flat Topography Smaller Interval than Steep
• Engineering Maps require Smaller Interval

7
Map PURPOSE

• 2.1. General PLANNING
• Maps used to determine overall feasibility
• Smaller scale maps (125,000)
• Regional and larger area patterns
• Past and future (projected) development trends
• Widest range of possible subject matter
• land use, transportation, hydrology, utilities,
  political boundaries, cadastral, demographics
• 2.1.1. Site Planning (micro planning)
• Precede Design/Construction Maps
• Scale ranges from 1500 to 112,500

8
2.1.2. Local/City Planning

• (Map Purpose - Planning maps, cont.)
• to assess community-wide patterns trends
• also used for
• Emergency Services (police, fire)
• School District Planning
• esp. for Bus Routing Planning
• Scale depends on Community Size
• fewer maps better/easier for planners
• Generally from 15,000 to 125,000
• Larger Scales used for highly congested
  built-up areas

9
Regional Planning - Map Purpose, cont.

• 2.1.3. Regional Planning
• Relationships among communities
• natural resources, communications,
  transportation, economic development
• Coast Zone Management other Special Areas
• Scales from 112,500 to 1125,000 (or smaller)
• 2.1.4. National/International National Planning
• SE Asia, U.S., W. Europe / Hemisphere, Global
• Defense, Transportation, Navigation
• Scales from 1125,000 to 160,000,000

10
LSA (Map Purpose, cont.)

• 2.2. Area Survey / Land Suitability Analysis
• Map areas Not Suitable (Negative Controls)
• Map areas Suitable (Positive Controls)
• Controls
• natural (topography, soils, hydrology, weather)
• human (ownership/ROW, land uses, pollution,
  regulations)
• LSA used to determine Atlernative Plans
• Site or Local Planning Scales - typically
• 2.3. Alternative Plan Surveys
• Each Alternative Plan is Evaluated on
• Natural Environmental Controls and Human Controls

11
Rational Planning Model

• Steps
• 1 - Define Goals/Objectives
• 2 - Collect Data
• 3 - Develop Alternative Plans
• 4 - Evaluate Alternatives
• 5 - Select and Implement the Preferred
  Alternative
• 6 - Evaluate Implementation

12
2.4. ENGINEERING PLANS

• DESIGN SURVEY
• For final design and costing-out of the project
• Scale ranges from 1500 to 12,500
• LOCATION CONSTRUCTION SURVEY
• used to contractors
• Scale ranges from 125 to 1600
• AS-BUILT SURVEYS
• Maps of what was Actually Built
• building footprint location, orientation, and
  size
• used for Maintenance and Future Planning
• Same Scale as Construction Survey

13
SCALES IN GENERAL - SUMMARY

• 150,000 and 125,000
• 125,000 - 1 cm 250 meters
• Regional Planning
• 110,000
• City-wide Planning
• 15000
• Small Area Planning, Land Suitability Analysis
• 11000
• Site Planning, LSA
• 1500
• Civil Engineering Design
• 1100
• Site Design Construction

14
3. EXAMPLES of SCALE

• 3.1. Highways Water Supply Storm Sanitary
  Sewer Electricity and other Utilities
• 1 25,000 - master transportation/water planning
  in Large Cities and Watersheds
• 1 1,200 to 110,000 - smaller towns and
  communities
• Sewers 15,000 - floodplain areas outside of
  city
• 1 2,500 - preliminary Site Planning
• 1 1,200 to 1500 - final Site Engineering
• Also Cadastral Maps For Property Acquisition
• 1 5,000 - general studies
• 1 500 - more detailed studies

15
3.2. Land Use Planning Traffic Engineering and
Parks Recreation Planning

• Scale depends on Area covered Needs of each
  Agency
• 1 10,000 to 1 25,000 for General Studies
• Traffic Flow, Street Widths Grades (slope)
• Regional Land Use and City-wide Parks
  Recreation
• 1 2500 to 1 1000 for Detailed Studies
• Specific Corridors, Expressways, Signalization,
  Off-Street Parking, Street widening projects
• Most common for Land Use and Recreation
  planning
• 1 500 to 1 250 for Major Problem
  Locations
• Congested intersections Signs signal details
• often enlarged from 12,500 scale
• Redevelopment Agency scale
