Sec. 9-3.602. Lots.

Each sideline of a lot in any proposed subdivision shall be as close as is practicable to perpendicular to the center line of the street at the point at which the lot side line terminates. All lot lines shall comply with Section 9-3.908 of Article 9 of this chapter at the time of the recordation of the proposed subdivision. All lots in a proposed subdivision shall conform to the minimum lot area and width requirements of the zone in which the proposed subdivision is located. No lot shall have less than forty (40’) feet of frontage, and no staff of a flag lot shall be less than twenty (20’) feet wide. All residential, commercial, and industrial lots shall have direct access to public streets, except where private street, common driveway, or other reciprocal easement rights are specifically approved by the City and made a matter of record in the office of the County Recorder. In determining the permissible minimum lot area of lots less than ten thousand (10,000) square feet in size, all public utility line easements shall be excluded even though such easements are included in the lot design.

Sec. 9-3.603. Size requirements.

(a) All proposed lots or parcels shall have not less than the minimum width and length required by the zoning regulations as specified in Chapter 4 of this title. All proposed lots or parcels of less than ten (10) acres gross shall also have not less than the minimum net area required by said zoning regulations. Each lot or parcel shall have a conforming width at the front yard setback or building line required by the applicable zone classification. The average lot depth shall not be greater than three (3) times the lot width at the setback or building line, unless the Planning Commission determines that topographic features in the area justify a greater average depth.

(b) Whenever a division of land results in a lot or parcel for which the only means of access is by way of an easement or the staff on a flag lot, the easement or staff shall be considered as a public road or street for the purposes of determining the size of the lot.

Sec. 9-3.604. Street rights-of-way.

The street layout of a proposed subdivision shall be consistent with all street right-of-way designations shown on the Circulation Element of the General Plan of the City or applicable Specific Plans at the time the tentative map is approved. The street layout and widths of rights-of-way shall also comply with the requirements of the City of Thousand Oaks Improvement Standards and Specifications. The requirements of this section affecting road alignments may be waived or modified if the Planning Commission finds, after making an appropriate study and investigation of the physical features of the area and the general alignment of the existing roadway, and considering such other engineering information as may be available, that the street rights-of-way shown on the Circulation Element or applicable Specific Plans for the area of the subdivision would not follow the existing right-of-way center line and would follow an alignment other than the existing alignment.

Sec. 9-3.606. Drainage easements.

The design of a proposed subdivision shall be such as to provide for the proper drainage of the proposed subdivision and all lots and improvements therein, based on the runoff which can be anticipated from the ultimate development of the watershed area in which the subdivision is located. The design shall be such that there are no undrained depressions. Easements shall be provided within the proposed subdivision as may be necessary to provide for the proper drainage of the proposed subdivision and which are included in the Master Drainage Plan for the Conejo Valley approved by the City or the Comprehensive Plan of Flood Control Channels approved by the Board of Supervisors of the Ventura County Flood Control District. Access to open channels included in the Master Drainage or Comprehensive Plan shall be provided along the entire length of the channel. Access to underground drainage conduits shall be provided by an easement not less than ten (10’) feet in width directly above the entire length of the conduit, which shall not permit any structures, including masonry walls to be installed or maintained. The design of the proposed subdivision shall be such as to protect the subdivision and the lots and improvements therein from off-tract drainage or flood damages. The design shall also ensure that all public facilities, such as sewer, gas, electrical, and water systems, are located, elevated, and constructed so as to minimize or eliminate flood damage. Further, the design shall provide that any concentrations or increases or surface water resulting from the development of the proposed subdivision are conveyed by means of adequate facilities to suitable natural watercourse or drainage facility in the area. Off-tract easements as may be necessary for such facilities shall be provided by the subdivider. All easements required to be provided pursuant to this section shall be offered for dedication at the time the final map or parcel map is filed for approval.

Sec. 9-3.607. State highways.

If an existing or proposed State highway abuts a proposed subdivision, the subdivider shall secure all pertinent road data and specifications and shall provide that the design of the proposed subdivision is compatible with the use of such

State highway. (Ord. 744-NS, eff. April 17, 1980)

Sec. 9-3.608. Public water agencies.

Whenever a proposed subdivision requiring a final map is located within the boundaries of a public water agency or a private service company willing and able to provide water service to the lots, the agency or company shall be chosen as the water purveyor for the proposed subdivision.

Sec. 9-3.610. Street lighting.

Prior to the recordation of the subdivision map, if so directed or required, the subdivider shall cause the area within the subdivision to be included in the City of Thousand Oaks Municipal Lighting District or appropriate maintenance assessment district and any applicable subzone thereof providing street lighting. The Planning Commission may waive such requirement for parcel maps if the Planning Commission finds that inclusion within such a service area is unnecessary because of the size or location of the proposed parcels or that inclusion could be more appropriately a condition of approval of a future development plan.
