RECORD OF DECISION
US Highway 89
Right Fork in Logan Canyon to Garden City
Final Environmental Impact Statement (FEIS)
Cache and Rich Counties, Utah
A. DECISION
The Federal Highway Administration (FHWA) concurs with the Utah Department of Transportation
(UDOT) in its selection of the Preferred Alternative as modified in this Record of Decision (ROD)
for improvements to US Highway 89 (US-89) between Right Fork, milepost (mp) 383.47, and State
Road 30, mp 411.75, in Garden City. The modified Preferred Alternative is described in Section
B below. The modified Preferred Alternative is as presented in the Final Environmental Impact
Statement (FEIS) with the following modifications made as a result of input received on the FEIS
and subsequent meetings and field reviews in order to further minimize harm to wetland/riparian
habitat, visual resources and Section 4(f) resources:
* The Lower Middle Canyon section has been extended 500 feet to mp 387.57 to better fit
the surrounding terrain. The roadway begins to move further away from the river at
this location.
* Consolidation of parking for Section 4(f) Site 6, Ricks Spring, has been eliminated. This
eliminates the left turn lane and retaining wall adjacent to the river. A shorter retaining wall
set back from the river may still be required just south of the site.
* Section 4(f) Site 13, Winter Access Parking, will be reestablished at a lower elevation so that
access can be maintained.
* Relocation of the Limber Pine Trailhead has been eliminated.
* The detour at Burnt Bridge has been eliminated and widening will occur on the upstream
side.  This reduces the impact on riparian habitat.
* For the first eight miles of the Upper Canyon (from mp 391.6 to Beaver Mountain road
intersection), the previously proposed roadway width of 40 feet has been reduced to 34 feet.
This reduces the impact on wetland and riparian areas. For areas with passing lanes through
this eight miles, the previously proposed roadway width of 47 feet has been reduced to 44
feet.
* The left turn lane at Temple Fork has been eliminated. Minimum roadway improvements
at this site include a 34' section on US-89 and an improved vertical grade approach of
Temple Fork road. Other improvements, such as an uphill right turn lane and an improved
horizontal angle of approach of Temple Fork Road, are secondary improvements which will
only be constructed if they do not impact the river or require a substantial retaining wall.
