Wood Construction: Alternate Plan
Fences should be constructed of quality materials and built to withstand the elements of wind, water, and sun. Listed below are standards that will facilitate the longevity of a visual barrier.
Posts:
- The support posts should be a steel construction with a minimum length of 8 feet, a minimum diameter of 2 inches and have rain caps.
- The support posts should be placed a minimum of 2 feet 6 inches into the ground using 90 pounds of concrete per post for stabilization.
- The top of the concrete should be exposed above the finished grade and slope away from the post.
- Posts should have a maximum spacing of 8 feet.
- Posts should be placed without any concrete under them to allow water to drain away from the post.
Rails:
- The rails should be treated wood or wood of natural resistance to decay such as redwood or cedar, a #1 grade wood, and supported by the posts at a maximum interval of 8 feet.
- The rails should be 2" x 4" x 8’ (16’ long for best results) and attached to the posts utilizing a 2" x 4" x 10" steel angle iron and 1/4 inch "U" bolts. Note: When using 16 foot rails the butted ends should be staggered with the other rails giving the fence better support.
- A minimum of two rails and preferable three rails should be used.
Slats:
- The slats should be a minimum of 1" x 4" treated wood or wood of natural resistance to decay such as redwood or cedar, a #1 grade wood, and no greater than 6 feet high without obtaining a building permit.
- A space of 2 inches should be left between the bottom of the slates and the ground. The slats should be installed with no space between them.
- The slats should be fastened using galvanized 6 penny nails or 1-1/2" inch staples placed pneumatically.
- Pecky cedar or grape stakes should not be acceptable in the construction of the visual barrier.
