17.37.010 Purpose and Relationship to Base Zoning District.

This chapter establishes the Parker Avenue overlay district. This district is intended to be combined with the Residential District R-1A and is designed to provide development standards that are adapted to the unique circumstances of a large cluster of small lots. In any conflict between the standards of the R-1A Base District and this overlay district, the overlay district regulations shall apply. (Ord. 587 § 1, 2010)

17.37.020 Characteristics of the District.

The Parker Avenue Overlay District (P) provides for the development of single-family residential uses on lots located in the R-1A District which are significantly less than one acre in area and which front on a seventy-footwide public right-of-way. This right-of-way is significantly wider than the Town’s standard local street. The Parker Avenue overlay district allows for more total floor area and more second story floor area than the base R-1A district. Unchanged R-1A rear setbacks and reduction in permitted heights for new development are intended to minimize any adverse impacts on the privacy or views of neighboring homes. (Ord. 587 § 1, 2010)

17.37.040 Development Standards Modifications.

A. Height. The standard maximum building height for main buildings shall be twenty-eight feet; provided, that vertical sidewalls and columns may not exceed twenty feet. End walls shall be perpendicular to lot depth.

  • B. Maximum Floor Area Ratio. The maximum floor area ratio shall be determined by the following equation:

Floor area in square feet = (lot size in square feet × .165) + 1,500 square feet

The floor area above the first floor of the main building for all lots shall not exceed one thousand one hundred thirty-two square feet.

The Atherton Municipal Code is current through Ordinance 677, passed February 18, 2026.
