Proposed Helicopter Pad

Proposed Helicopter Pad

• By Lesley Stein and Jordan Kittle

2
Goal

• To use GIS in order to locate an appropriate site
  for a helicopter landing pad in Swanton Ranch
• To use federal guidelines and local features to
  establish the most suitable site
• Provide a map exhibiting proposed area

3
Criteria

• Road
• No closer than 300ft and no farther than 1000ft
• The helicopter landing pad should be accessible
  to roads, but placement should not result in air
  traffic flying too low over these roads.
  Following federal guidelines, the site should be
  at least 300 away from any roads, allowing
  pilots full approach and takeoff distance before
  crossing any roads.
• Convenience of transportation after landing

4
Criteria

• Horse Trails, Streams, Railroads
• To ensure site is not too close to any of these
  features
• Horse Trail- At least 50ft away. To make sure we
  did not build on top of a horse trail
• Stream- At least 500ft away. This value is
  slightly increased to ensure flooding and erosion
  are avoided
• Railroads-At least 300ft away. To accommodate
  for the federally regulated 300ft safety buffer

5
Criteria

• Soil- Low shrink swell
• Soils with a high shrink swell value can be
  difficult to build on because the shrink-swell
  action can crack foundations. The Central Coast
  is home to many areas of shrink swell soil.

6
Criteria

• Slope- less than 11
• federal guide lines call for no greater of a
  slope than 11
• Land Use- Range
• To ensure our site would not be located in
  forest, crop land, or structure zoning.
• Vegetation- grass land, barren, or brush field
• To ensure our site would clear of impeding
  vegetation

Additional Benefits of Location

• Near Coast
• Provides helicopter transportation to marine and
  terrestrial peoples
• Enjoyable view

• Near a Highway
• Quick access to a main road in case of
  emergencies
• Away From Trees
• Pilot friendly

Suggestions

• Transportable Helicopter Pad
• Should environmental factors alter helicopter pad
  can be moved to another suitable location
• For example, if an endangered species such as a
  bird were to nest near a helicopter pad that
  helicopter pad is now restricted from use
