Red Rock Crossing (circa 1994)

Sedona seeks alternate route to "Y"...again

by Carl Jackson

Sedona, AZ - At the March 25, 2008 Sedona city council meeting, design firm EDAW will present the results of its study of alternative solutions to the existing route in Sedona at the "Y" intersection of Hwy 179 and Hwy 89A.

The idea of an alternate route has been around for more than 25 years, with the most commonly discussed solution being a bridge at Red Rock Crossing connecting West Sedona to the Village of Oak Creek. Proponents say a new route would relieve traffic congestion and lead to improved response times for emergency vehicles.  Those against an alternate route cite the negative impact on the environment and neighborhoods.

Prior to moving forward, the city will need the support of Yavapai County and request permission for a right-of-way from the U.S. Forest Service under the National Environmental Policy Act that demonstrates, via an environmental impact statement, that there is clear purpose and need for an alternate route.

As background, in 1978, Oak Creek floods washed out a water level concrete slab at Red Rock Crossing, and in 1993 the Citizens for an Alternate Route (CFAR) organized to promote a new bridge to replace the slab.  A study done in the mid 90's indicated that the cost to build a bridge at the Red Rock Crossing would be approximately $28 million (not inflation adjusted).

In 1997, Yavapai County submitted an environmental impact statement to the Environmental Protection Agency that proposed the following: "...4-span concrete bridge designed for 2-lane traffic (2 twelve foot wide travel lanes) [that would require a]...realignment of both the Verde Valley School and Upper Red Rock Loop roads..."

The proposal never moved forward because in 1998 Yavapai County, led by Yavapai County Supervisor, Chip Davis, withdrew its support, citing escalating costs.  The Citizens for an Alternate Route sued Yavapai County but lost because the presiding judge ruled that Yavapai County couldn't be forced to build a bridge.

In March 2006, the Sedona Fire District issued a position statement "in strong support of an additional passageway between West Sedona and the Village of Oak Creek...at or near Red Rock Crossing...This new passageway will save lives by bringing the Village of Oak Creek and West Sedona closer together, considering that the safe, rapid, and reliable emergency response is what the Sedona Fire District feels is the best for transporting patients, this is the shortest and more direct route preferred."

In July 2006, the city council placed "circulation, traffic flow, and public safety" as a top city priority and hired EDAW to study alternative route solutions.

In its March 2008 study entitled, "Sedona Transportation Feasibility Study" (the "Study"), EDAW evaluated five possible alternative routes, including the greater use of public transportation, and concludes that a route at Red Rock Crossing "presents the fewest constraints."

According to the Study, the traffic volumes collected in August 2003 ranged from roughly 14,000 vehicles per day (vpd) in the Village of Oak Creek to 21,000 vpd near the "Y." The overall daily volumes on SR 179 increase roughly 5 percent on Saturday from an average weekday, and the daily traffic volumes along SR 179 are anticipated to increase from 20 percent to 45 percent by year 2030.

The Study goes on to say, "The future Saturday peak hour travel delays at the intersection of SR 179 and SR 89A are expected to be 85 seconds with an average number of 76 vehicles queued at the intersection (sum of all approaches). The consequences of these delays may include greater driver frustrations, increased travel times for regional and local traffic destined to points north and west, and potential impacts to emergency services."

Preferred alternate route as determined by EDAW in its "Sedona Transportation Feasibility Study."

According to the Sedona Fire District, emergency response times are 5:46 minutes for the Village “proper,” 7:13 for Sedona, and 10:34 for the midpoint area between the two (4 to 8 minutes is considered standard). 

Consequently, the Study concludes that improved emergency response times should not be a principle rationale for an alternate route, unless others issues, like the 11 new roundabouts along SR179, increase response times further.
