Sun Valley OKs 
ordinance to 
protect hillsides

Sun Valley City Council members Thursday, 
Aug. 14 voted unanimously to adopt a new ordinance designed to restrict 
development on hillsides and ridges throughout the city.
Adoption of the so-called "Hillside 
Ordinance" was a momentous occasion for the council. Despite an overall lack of 
fanfare during the vote, the move could serve to protect Sun Valley’s rural 
atmosphere from the unchecked development that has scarred the landscapes of 
many Rocky Mountain villages.
Provisions in the new ordinance, however, 
will not be incorporated into the city zoning code until after a second and 
third public reading of the legislation is conducted by the council. The 
readings will occur during future meetings of the council.
Len Harlig, former Blaine County 
commissioner, praised the council for enacting legislation to protect the 
natural landscape of Sun Valley. "I’m very grateful you have taken this step," 
he said.
As approved, the new ordinance will amend 
Sun Valley’s existing zoning regulations to effectively restrict the development 
of—and creation of—steeply sloped parcels.
The approved proposal comprises a single 
ordinance that would add new language to two distinct sections of the zoning 
code.
Generally, the ordinance will restrict the 
height and design of buildings planned for hillside parcels, as well as offer 
incentives to developers to lessen the impacts of projects in sloped areas.
In one key modification made Thursday, the 
council ordered city staff to install in the document new language that will 
altogether ban construction of buildings on hillsides with a slope of 25 percent 
or greater. The blanket ban on building on the steepest of slopes closely 
mirrors one that has been enacted by Blaine County.
However, Mayor David Wilson noted that the 
ban would not apply to most residentially zoned land. Land parcels in the city 
with more than a 25 percent slope are almost exclusively included in the city’s 
Outdoor-Recreation zoning district, he said.
Other key provisions of the ordinance 
include:
· 
 A ban on the creation of new parcels, through subdivision, that would have 
building envelopes with a slope greater than 25 percent—except as part of an 
approved planned-unit development. Generally, new lots would be allowed a 
maximum of one-half of the building envelope to be on a slope between 15 percent 
and 25 percent.
· 
 Language mandating the use of stepped building forms, natural colors and 
materials, sloped roofs and landscaping for development of most building sites 
with slopes greater than 15 percent. The percentage was set at 20 percent for 
the city’s Rural Estate and Ranch zoning district.
· 
 Language mandating that buildings shall "skyline"—a term to used to describe 
the effect of structures being outlined against the horizon.
· 
 A 35-foot height limit for structures in the city’s Rural Estate and Ranch 
zoning district, plus a provision that no more than one third of any building’s 
roof area can exceed 30 feet above record grade.
· 
 New design-review criteria and language in the city’s subdivision code to 
minimize the effects on the landscape of grading, cuts and fills.
Councilman Latham Williams said he would 
like a final set of text changes to the ordinance to explicitly state that the 
city discourages applications for subdivisions of steep hillside parcels. "We 
want to make it clear to developers that they don’t have the right to come in 
and build on hillsides," he said.
Adoption of the ordinance could prove to 
be a bright feather in the cap of council members who choose to seek reelection 
in November. Many residents for years have urged the city to pass legislation 
limiting hillside development.
