  • City of Cypress is located in Seismic Design Category D.
  • The ultimate wind speed is 110 mph. And ASD Basic wind speed is 85 mph, this can be verified with ASCE 7-10, Table 16-1, 2013 CBC Table 1609.3.1. Most areas of Cypress can be classified as wind exposure category C. However, some areas may meet the criteria for exposure B (>= 1,500 feet away from open fields) and the design professional is responsible for justifying the exposure selected for the specific area of construction
  • For additions and remodels, the soil bearing pressure is based on 1,500 pounds per square foot, unless a higher value is justified by a soils report. A 1/3 increase is allowed for wind/seismic.
  • For retaining walls, lateral soil bearing pressure is based on 100 pounds per square foot per foot below natural grade, unless a higher value is justified by a soils report. Without a soils report the coefficient of friction is 130 psf x contact area of footing or 1/2 DL whichever is less.
  • The climate zone is Zone 8.
  • Rainfall design is based on two inches of rainfall per hour.
