Elsewhere, such fence shall be a solid fence not less than six (6) feet high and not more than seven (7) feet high. (Ord. 427-AC.)
Where a fence is required along a property line and an existing fence is located on the opposite side of the property line, the city planner may suspend the requirement for the fence on the subject property to the extent he finds the adjacent existing fence substantially serves the purposes of the fence requirement. Such suspension shall be subject to a recorded agreement running with the land, satisfactory to the city planner, executed by the owner of the subject property, guaranteeing the construction of the required fence at such time as the fence on the adjacent property is removed or no longer found acceptable by the city planner.

These projects are exempt from the requirement of having a State of California professional authorized to design a landscape or an irrigation system sign-off; as well as lower permit fees.


Projects will follow guidelines of the Governor’s Executive Order EO B-29-15, requiring project plans to be designed/approved by a person authorized by the State of California to design a landscape or an irrigation system. These projects require the calculation for the Maximum Applied Water Allowance (MAWA); the development of a hydrozone table to calculate the Estimated Total Water Use (ETWU) does not exceed the Maximum Applied Water Allowance (MAWA). It requires more attention to the design of the irrigation system assuming a wider range of plant factors will be part of each hydrozone.

Elsewhere, such fence shall be a solid fence not less than six (6) feet high and not more than seven (7) feet high. (Ord. 427-AC.)
Where a fence is required along a property line and an existing fence is located on the opposite side of the property line, the city planner may suspend the requirement for the fence on the subject property to the extent he finds the adjacent existing fence substantially serves the purposes of the fence requirement. Such suspension shall be subject to a recorded agreement running with the land, satisfactory to the city planner, executed by the owner of the subject property, guaranteeing the construction of the required fence at such time as the fence on the adjacent property is removed or no longer found acceptable by the city planner.

Projects will follow guidelines of the Governor’s Executive Order EO B-29-15, requiring project plans to be designed/approved by a person authorized by the State of California to design a landscape or an irrigation system. These projects require the calculation for the Maximum Applied Water Allowance (MAWA); the development of a hydrozone table to calculate the Estimated Total Water Use (ETWU) does not exceed the Maximum Applied Water Allowance (MAWA). It requires more attention to the design of the irrigation system assuming a wider range of plant factors will be part of each hydrozone.
