EXECUTIVE SUMMARY:
Council adopted the 2003 International Building Codes in 2004, including the 2003 International
Residential Code (IRC). Chapter 3 of that Code establishes the requirements for building planning
and an amendment approved at the time of adoption was a wind speed of 110 miles per hour, 3- second
wind gust. The 3- second wind gust was a new measure of wind speed adopted in the international
codes. Previous codes used a sustained wind speed.
This ordinance was amended by Council on first reading to change the wind speed to 100 miles per
hour, 3- second wind gust, exposure C. Exposure C requires engineering for any structure over three
stories.
Action on this item implements Council's strategic goals ofproviding better quality housing stock and
planning for growth and development.
COMMISSIONBOARD RECOMMENDATION:
The Building Code Advisory Board recommended adoption of the 110 miles per hour, 3- second wind
gust requirement.
STATEMENT OF THE ISSUES:
At the time of adoption of the 3- second wind gust standard, many products had not been tested. Now
that tests have been completed, many products now meet the 110 mph 3- second wind gust
requirement.
The dividing line between the 110 and 100 mph zones is Kipling. Golden and Lakewood have
adopted 100 mph. Arvada has four zones.
The 110 standard requires all structures to be engineered, including all wood -frame structures such as
single family structures and additions, carports, garages, sheds, and other minor structures. The 100
mph standard does not.
The wind speed requirement affects other areas of building planning, not just shingles. Other areas
affected are the structure, windows, sheer walls, and uplift on porches and carports. The design of
membrane structures and signs is also affected.
ALTERNATIVES CONSIDERED:
1. Retain the 110 mph, 3- second wind gust standard.
2. Create two different zones as in the proposed ordinance.
FINANCIAL IMPACT:
There will be no financial impact to the City as a result of adopting this ordinance.
RECOMMENDED MOTION:
"I move to approve Council Bill 31 -2006 on second reading and that it take effect 15 days after final
publication."

EXECUTIVE SUMMARY:
&*Jcs.��
City Manager
Council adopted the 2003 International Building Codes in 2004, including the 2003 International
Residential Code (IRC). Chapter 3 of that Code establishes the requirements for building planning
and an amendment approved at the time of adoption was a wind speed of 110 miles per hour, 3- second
wind gust. The 3- second wind gust was a new measure of wind speed adopted in the international
codes. Previous codes used a sustained wind speed.
This amendment was adopted because the IRC indicates that the Front Range is in a special wind
region. The 110 mph requirement comes from the results of a wind study commissioned by a number
of Front Range communities in 2005. This study concluded that about half of the City was susceptible
to 3- second wind gusts of 110 miles per hour.
This item was discussed by Council at a study session on November 6, 2006. The consensus of
Council was to bring forward an ordinance amending the IRC to create two wind load requirements in
the City: 110 miles per hour west of Kipling and 100 miles per hour east of Kipling. The proposed
ordinance amends the prescriptive energy accordingly.
Action on this item implements Council's strategic goals of providing better quality housing stock and
planning for growth and development.
COMMISSIONBOARD RECOMMENDATION:
The Building Code Advisory Board recommended adoption of the 110 miles per hour requirement.
STATEMENT OF THE ISSUES:
At the time of adoption of the 3- second wind gust standard, many products had not been tested. Now
that tests have been completed, many products now meet the 110 mph 3- second wind gust
requirement.
The dividing line between the 110 and 100 mph zones is Kipling. Golden and Lakewood have
adopted 100 mph. Arvada has four zones.
The 110 standard requires all structures to be engineered, including all wood -frame structures such as
single family structures and additions, carports, garages, sheds, and other minor structures. The 100
mph standard does not.
The adoption of two wind speeds for the City, while technically implementing the results of the wind
study, will create confusion for the contracting community and staff. Retaining the 110 mph standard
will result in half of the City being over - designed and a 100 mph standard will result in half the City
being under - designed.
The wind speed requirement affects other areas of building planning, not just shingles. Other areas
affected are the structure, windows, sheer walls, and uplift on porches and carports. The design of
membrane structures and signs is also affected.
Other options presented in the staff memo for the study session included:
Retain the 110 mph requirement.
Lower the requirement to some other wind speed citywide.
ALTERNATIVES CONSIDERED:
1. Retain the 110 mph, 3- second wind gust standard.
2. Create two different zones as in the proposed ordinance.
3. Lower the requirement to 100 mph, 3- second wind gust.
Staff recommends that one standard be adopted for the entire City: 100 miles per hour, 3- second wind
gust, exposure C. Exposure C requires engineering for any structure over three stories.
FINANCIAL IMPACT:
There will be no financial impact to the City as a result of adopting this ordinance.

after final publication."
To amend the ordinance as proposed, add one of the following amendments:
Option A:
Wind speed is 100 mph, 3- second wind gust, exposure C.
Option B:
To keep the wind speed citywide at 110 mph, 3 second wind gust, the motion should be to table the
council bill indefinitely.

Questions and comments followed.
Page -2-
Mr. White suggested that instead of having the 90% requirement, language be added to say Perforr
RES check or COM Check and he is trying to bring in the load calculations as well. Put that in as tl
2 options in the Prescriptive Energy Code. Then it is truly is a choice. Do your load calculations an
maybe only need a 70% or 80% furnace to meet the load calculation. That in combination with stor
doors gets you past RES check. It would give all kinds of options to meet the National Energy Cod(
We don't want to repeal the International Energy Conservation Code.
Consensus was 8 in favor to look at Mr. White's recommendations on first reading.
Councilmember Berry asked for consensus to create two different wind zones (110 and 100 mph) fc
different areas of the City as outlined in the study. Consensus was 8 in favor.
Councilmember Gokey asked for consensus to pass the NEC in its original entirety, excluding the
removal of conduit and extra wire. Consensus was 5 in favor with the Mayor breaking the 4 -4 ti
Consensus was 8 in favor to bring this back to Council at Mr. White's discretion.

Mr. White suggested that instead of having the 90% requirement, language be added to say Perforr
RES check or COM Check and he is trying to bring in the load calculations as well. Put that in as th
2 options in the Prescriptive Energy Code. Then it is truly is a choice. Do your load calculations an.
maybe only need a 70% or 80% furnace to meet the load calculation. That in combination with stop
doors gets you past RES check. It would give all kinds of options to meet the National Energy Code
We don't want to repeal the International Energy Conservation Code.
