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."

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.

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.
