Epa wind zone map. 14 and 25 year design life wind map (ASCE 7-05) is shown below. Wind speeds in Zone IV (red), where the risk of extreme windstorms is greatest, can be as high as 250 miles per hour. gov Wind Map 2009 AASHTO Wind Map All fixtures and arms are assigned an EPA value (Effective Projected Area) which is defined as the maximum two dimensional area multiplied by the drag coefficient (Cd) designated by AASHTO. To determine if your selected pole will work for your project, you must consider the light pole’s total EPA and the wind speed of the project location. com. AASHTO Wind Map As Defined by AASHTO, an EPA value (Effective Projected Area) is a coefficient used by the lighting industry to determine how much force a luminaire will apply to the mounting brackets or pole at a given wind velocity. Search 1,224 up-to-date wind power zone maps within the USA. How EPA Wind Ratings Are Calculated Wind rating calculations combine three critical factors: Wind Pressure Quickly retrieve site structural design parameters specified by ASCE 7-10, ASCE 7-16, and ASCE 7-20, including wind, seismic, snow, ice, rain, flood, tsunami, and tornado.
