Pleasanton City Zoning Code
CHAPTER 18
64 RO RESIDENTIAL OVERLAY DISTRICT
§ 18.64.010 Purpose.
§ 18.64.020 Initiation.
An amendment to reclassify property to an RO district may be initiated by the owner, the planning commission, or the city council. It is the intent of this section that the commission shall initiate RO Districts in predominately undeveloped areas where the application of the requirements of this chapter would contribute toward achievement of the objectives prescribed in Section 18.04.010 of this title, and the purposes prescribed in Section 18.64.010 of this chapter.
(Prior code § 2-8.15)
§ 18.64.030 Applicability.
A.
The RO district shall be established only in conjunction with other districts, but shall not be combined with a PUD district. An RO district shall overlay whatever other district designation is applicable to the area in which the RO district is established.
B.
The provisions of this chapter shall apply in RO districts, which districts shall also be subject to other provisions of this title, including the provisions applicable to the particular district underlying an RO district, provided that where regulations conflict, the provisions of this chapter shall control.
C.
An application to amend the ordinance codified in this chapter so as to change district boundaries underlying an RO district shall not be construed as a request to change the boundaries of the RO district unless such change is specifically requested in the application.
D.
The requirements of the RO district shall not apply to developed residential lots, to property included in a recorded final subdivision map or valid approved tentative subdivision map, or to annexed territory in which the development pattern has been specifically committed by an annexation agreement. The requirements of the RO district shall apply to property included in an expired tentative subdivision map. Parcels less than five acres on the effective date of the ordinance codified in this chapter, May 3, 1968, may be exempted from the requirements of the RO district, provided that the planning commission shall find that the exemption will not be detrimental to achievement of the purpose of this chapter.
(Prior code § 2-8.16)
§ 18.64.040 Lot size regulations and average density.
Where subdivision and initial development of land after the effective date of the ordinance codified in this chapter, is proposed, the lot size yard requirements and density controls provided in Table 18.64.040 shall apply, in addition to those of the underlying district.

§ 18.64.050 Limitation of RO requirements.
The increased requirements set by the RO district in Section 18.64.040 shall have no further force or effect upon an individual residential lot after construction and actual occupancy of the single-family dwelling.
(Prior code § 2-8.18)
§ 18.64.060 Permitted average density.
Within the limitations of minimum lot size of the underlying zoning and the average lot size established by Section 18.64.040, the average gross residential density established by Section 18.64.040 for the particular underlying basic zoning may be achieved by the establishment of small RM districts, unless the planning commission finds that such districts in a particular area would be detrimental to the orderly development of the area and inconsistent with the purposes in Section 18.64.010.
(Prior code § 2-8.19)
§ 18.64.070 Size and location of RM districts.
RM districts should be located throughout the residential area on thoroughfares or collector streets, and should be used as transitional development between neighborhood commercial areas and R-1 residential areas. RM districts within a tract that are not used as transitional development shall not be larger than three acres per district and separation shall be 300 feet or more. An RM district used as a transitional development shall not exceed six acres. RM districts surrounded by R-1 districts shall be RM-4,000 or RM-2,500. RM districts used as transitional developments shall be RM-4,000, RM-2,500 or RM-2,000.
(Prior code § 2-8.20)
§ 18.64.080 Area plan requirement.
In addition to the requirements established by Article III of Chapter 18.12 of this title wherever an RO district is established, any subsequent application for change of the underlying zoning shall be accompanied by an area plan submitted for planning commission approval in conjunction with the rezoning request. Such area plan shall include lot patterns, street systems, location and size of RM districts, and density calculations to clearly demonstrate that the average gross residential densities prescribed in Section 18.64.040 have not been exceeded.
