Existing Conditions
The Grizzly Mountain Lookout site is located on top of the mountains northwest of Inchelium, in Okanogan County Washington. There is primitive road access to the site but the tower and communications building are located up on a small rocky rise.

  • There is no tower that is being utilized as a communication Tower.
  • The antenna mounts and antenna mounting hardware for several antennas are rusting.
  • No lightning rod is placed to a height above the tallest antenna.
  • In general, the site is not adequately grounded. Sub-surface ground system cannot be verified. Site grounding is not in compliance and does not meet MOTOROLA R56 standards.
  • Site road access is good with winter access issues.
  • Site is not served by commercial Power. Primary power to this site is provided by a fixed angle solar array.
  • There is no emergency back-up power generator unit on auto start controls.
  • Install a TVSS or Transtector Surge Protector to protect communications equipment from transient voltage spikes.
  • The existing equipment shelter is poor condition. Equipment shelter is placed directly on ground.
  • Equipment shelter is not equipped for environmental conditions. No climate control (HVAC) or dust control. There are signs of rodent infestation present.
  • There is no security fence in place to restrict unauthorized personnel from accessing this structure or deterring vandalism and theft.
  • Climb Warning signs, RF Warning signs and No Trespass signs were not posted.
  • It is ICI’s professional opinion it would be most feasible to upgrade the site by erecting a new tower 150’ self-supporting lattice tower and placing new 12’ x 30’ Pre-fabricated concrete equipment shelter with the emergency back-up generator housed in the equipment shelter.
  • Location for tower placement would be on top where current equipment shelter is located and new equipment shelter located below at head of access road and cable up to tower.
  • It also would resolve all site deficiencies and consolidate all antennas and ancillary equipment to a single structure.
