Sun Valley inaugurates ‘Dark
Sky Ordinance’

Under provisions of a new
ordinance approved last week, Sun Valley residents should be able to
behold the heavens for years to come.
Sun Valley City Council members on
Thursday, March 18, unanimously passed a so-called "Dark Sky Ordinance"
that will limit the types of exterior lighting permitted on commercial
and residential properties.
The approval of the new exterior
lighting regulations makes Sun Valley the third city in the Wood River
Valley to adopt an ordinance designed to control light pollution.
Ketchum adopted its own set of regulations in 1999, followed by Hailey
in 2002.
"I think it’s important for
everyone in the city to realize how important this is," said Councilman
Blair Boand. "I think it’s a great document."
The ordinance—which was approved
to go into effect upon its signing by Mayor Jon Thorson—establishes
lighting regulations for all new construction and previously developed
properties. Existing residential, commercial and institutional
developments in the city will have 18 months to come into compliance
with the ordinance.
Generally, the ordinance mandates
that all exterior light sources in the city should be "downcast and
fully shielded," except in some specific configurations, including:
- Fixtures emitting the
equivalent light of a 60-watt bulb, which may be left partially
shielded if the lamp has an opaque top or is under a solid overhang.
- Floodlights with external
shielding and angled at 30 degrees so the light does not encroach on
adjacent properties or public rights of way. Floodlights must be
turned off by 11 p.m.
- Residential holiday
lighting, which may be used from Nov. 1 to March 15, if it does not
flash and is turned off by 11 p.m. each night.
Councilwoman Ann Agnew—before
voting in favor of the ordinance—expressed concern that the
legislation’s regulations could cost her and other property owners
substantial sums of money.
"I have twelve fixtures that I am
going to have to replace and it’s going to cost me about $3,000," she
said.
Agnew added: "I’m only going to be
one example of many many."
However, Sun Valley resident Steve
Pauley, who helped city staff craft the new regulations, said the costs
of retrofitting non-compliant fixtures should not be excessive to most
homeowners or businesses.
"In terms of cost of compliance,
homeowners will have to pay a little more to comply," he said. "But I
don’t think the expense is intolerable or too onerous."
Diane Shay, Hailey city planner,
said that city’s exterior lighting regulations have not required
large-scale lighting modifications by most homeowners.
"We have had very little in the
way of problems," Shay said.
The new ordinance provides that
the city can deliver a written notice to violators demanding that they
come into compliance.
If the violation is not corrected,
the city "may institute actions and proceedings, either legal or
equitable, to enjoin, restrain or abate any violations," the ordinance
states.
City Attorney Rand Peebles said
long-standing violations could result in a misdemeanor but downplayed
concerns that the city would have police monitor residents’ lighting.
"I don’t see police being involved
much at all," he said.
Several residents of the city and
Blaine County voiced support for the ordinance.
The Sun Valley Planning and Zoning
Commission and city staff began drafting the ordinance approximately two
years ago, but eventually postponed the project after a series of large
development proposals were submitted to the city in 2002.
Former Mayor David Wilson
requested last summer that the ordinance be completed.
