RE: Allowable Building Heights Maps and Highway 93 Bypass
Finished Surface
Dear Jerry:
As requested, we have created both Allowable Building Heights Maps
and a map showing the Highway 93 Bypass Finished Surface.
The Allowable Building Heights Maps were based on the "ultimate"
runway configuration for the Kalispell City Airport. The controlling,
lowest, airspace surface is a 40:1 departure surface, (See Departure
Surface Map). This departure surface is a defined area that ensures that
departing aircraft will have adequate clearances from structures.
We have also shown the Federal Aviation Regulations Part 77 Airspace
Surfaces (FAR 77), (See Airspace Surface Map). This surface consists of
several different airspace surfaces including the primary, transitional,
approach, horizontal and conical surfaces. We included this because
some of the northern portions of the Siderius Commons Site is unaffected
by the Departure Surface but is affected by the FAR 77 Surfaces. Please
be aware that the entire property, outside of the Departure Surface and
FAR 77 Surfaces shown are encircled by the Airport Horizontal Surface
with has an elevation of 3080.00 feet.
This airspace stuff can be confusing, but you don't need to be an expert in
understanding the Airspace Surfaces to determine your allowable
building heights. To determine the allowable building heights you only
need to determine the elevation at a point of interest on the ground
contours, determine your overall height of your building and check with
the Departure Surface or Airspace Surface, whichever the location is
located beneath. If the elevation of the highest point of the building is
less than the controlling airspace surface, then the building would not be a
penetration into the Kalispell City Airport's Airspace.
We have also converted the data for the Kalispell Bypass that was
provided to us by Stelling Engineers. We have created the finished
surface for the bypass and overlaid those on the existing contours
provided by Sands Surveying. Please note that the finished surface does
not include the bike/pedestrian path that is planned as part of the bypass
project. There was not enough information available at this time from
Stelling Engineers to include the bike/pedestrian path into the finished
surface.
Thank you for choosing us to perform this work for you and we hope that
we can be of further assistance during the development of this project.
Sincerely,
ROBERT PECCIA & ASSOCIATES
