Unless exceptions are granted under the provisions of Chapter 16.36, or in the approval of a planned unit development, all subdivisions and parcel maps shall meet the design standards of this chapter.
(Ord. 92-74)
A.
Curves. The radius of curvature, grade, tangents between curves and right-of-way intersection turn radius of streets shall conform with the minimum standards prescribed in the Lathrop improvement standards, as adopted or amended by the city council.
B.
Alignment of Streets. Streets located on opposite sides of an intersecting street shall have their centerlines directly opposite each other where it is possible; otherwise the centerline shall be separated by not less than 150 feet.
C.
Continuations of Existing Streets. Subdivision streets which constitute continuation of streets in contiguous territory shall be aligned so that their centerlines coincide. Where straight line continuations are not physically possible, such centerlines shall be continued by curves. The continuation of a street in contiguous territory may be required by city council where such continuation is necessary to maintain the function of the contiguous street or a desirable existing pattern of streets and blocks in the surrounding area.
D.
Intersections. Street intersections shall be as near right angles as practicable. In no case should the angle of intersection be less than 60 degrees.
E.
Streets in Subdivisions Adjoining Unsubdivided Land (Acreage).
1.
Stubbed Streets. Where a subdivision adjoins unsubdivided land, streets which may be necessary to assure the proper subdivision of the adjoining land shall be provided through to the boundary line of the subdivision. A temporary turnaround of a 50 foot radius shall be provided at the end of a stubbed street where it is determined by the planning commission to be necessary for the movement of emergency vehicles.
2.
Half Streets. Where a street is proposed adjacent and parallel to the boundary line of the subdivision, the subdivider shall dedicate such additional right-of-way and provide such additional improvements as may be necessary for the classification of street involved.
F.
Reserve strips.
1.
A one-foot reserve strip shall be provided at the dead-end of a stubbed street and shall be offered for dedication to the city for future street purposes.
2.
Where a half street is to be located adjoining unsubdivided land, a one-foot reserve shall be provided adjacent to the unsubdivided land, and shall be offered for dedication to the city for future street purposes.
3.
Reserve strips shall be designated on the final map of the subdivision, and shall be specifically referred to in the dedication certificate.
G.
Cul-de-sacs. Except where special circumstances of design are apparent, cul-de-sacs shall not be more than 500 feet in length, and shall terminate with a circular turn-around with a radius of not less than 50 feet from the center of the cul-de-sac to the right-of-way line.
H.
Frontage Streets and Nonaccess rights.
1.
Where property is to front upon an arterial street, a frontage street separated from the arterial street by a planting strip may be required for access to the subdivision.
2.
Where property is to front upon a limited access highway or freeway, a frontage street separated from the limited access expressway or freeway by a planting strip shall be required for access to the subdivision.
3.
Frontage streets will not be required when the lots of the subdivision adjacent to an arterial street, limited access expressway or freeway are oriented so as to back onto the arterial street, expressway or freeway and access rights thereto have been acquired previously by a public agency by purchase or dedication of waiver by the subdivider.
4.
Where lots are proposed to back onto an arterial street, expressway or freeway, and access rights to the rear of such lots are offered for dedication, an ornamental masonry wall or soundwall, not less than eight feet in height, shall be required by the city to be constructed along the rear-lines on the property side of such lots.
5.
Where a noise barrier is required under the circumstances of back-on lot design as provided under subsection (H)(4) above, the barrier may be substituted for the requirement of an ornamental wall or wall/fence.
6.
Irrigated landscaping shall be provided along the street, expressway or freeway side of a wall or noise barrier provided under subsection (H)(4) and (5) above.
I.
Private Streets. Private streets and alleys shall be permitted only if they are improved by the subdivider in accordance with the standards prescribed by this code, and a covenant is recorded in the office of the county recorder, for the benefit of the city, which stipulates that the responsibility for maintenance of the private street rests with the owners of property served by the private streets.
J.
Street Names. Street names shall conform with the official plan of street numbers and names and house numbers of the city, where applicable. Where the provisions of said official plan are not applicable, streets shall be named in accordance with the policy of the planning commission and the city council. Where streets are continuations of existing streets, the existing street name shall be used. Streets shall be named so as to avoid duplication with other streets throughout the county.

D.
Lot Boundary Lines. No lot shall be divided by the boundary line of a county, city school district or other taxing district.
E.
Lots With the Capability of Resubdivision. Where lots are sufficiently large enough to permit resubdivision at some future time, the location of lot lines and other details of layout shall be such that resubdivision may readily take place without violating the requirements of this chapter or the zoning code, and without interfering with the orderly extension of adjacent streets.
(Prior code § 159.140)
A.
Block Length. Blocks shall not exceed 1,000 feet in length except where necessitated by topographical or other physical conditions; provided, however, that longer blocks may be required adjacent to expressways, arterial and collector streets in order to reduce the number of intersections. Blocks less than 600 feet in length may be cause for disapproval of the tentative map.
B.
Block Depth. The depth of blocks shall be sufficient to allow for two tiers of lots with easements as required, but blocks shall not exceed 300 feet in depth except where necessitated by topographical or other physical conditions, or where permitted by provisions of the zoning code for the zoning district involved.
(Prior code § 159.140)
Easements shall be provided for the placement of overhead and underground utilities along property lines where necessary to provide the subdivision with electric power, telephone and cable services, street lighting, sewer lines, water lines, gas lines or drainage. Such easements shall be labeled "Easement for Public Utilities" and shall be provided subject to variations requested by public utility companies.
(Prior code § 159.140)
Where a subdivision adjoins a freeway and the general plan or an element thereof designates a freeway interchange or grade separation structure for location involving property of the proposed subdivision, the possibility of a freeway interchange, grade separation or other treatment shall be considered by the planning commission. The plan of the subdivision may be required to conform to prescribed conditions in anticipation of a grade separation, freeway interchange or other treatment, subject to the standards of the California Department of Transportation (Caltrans).
(Prior code § 159.140)
In the event that the subdivision is bordered or traversed by any watercourses, channels, streams or creeks, the subdivider may be required to dedicate rights-of-way or easements for storm drainage purposes conforming substantially with the lines of such watercourses, channels, streams or creeks, and shall dedicate such additional rights-of-way as may be required by the city engineer for structures or channel changes required for the detention and disposal of surface and stormwater, or for vehicular access along the watercourse necessary to permit the proper maintenance thereof when such maintenance is the responsibility of a public body.
(Prior code § 159.140)
Areas which are subject to the detention or ponding of surface water shall not be subdivided until necessary measures have been taken or are required to be taken as a condition of approval of the tentative or final map by the city council. The city engineer shall make an investigation and report to the planning commission on the adequacy of measures taken or proposed to be taken by the subdivider.
(Prior code § 159.140)
Where, in accordance with provisions of the zoning code, a use permit has been granted authorizing a planned unit development (PUD) on the land or a portion of the land proposed to be subdivided, the plan of the subdivision shall conform with the PUD as approved by the planning commission and city council. Exceptions to the subdivision regulations which are necessary to execute the PUD as approved by the commission and council may be authorized by the planning commission in accordance with the provisions of Chapter 16.36 and the zoning code.

(Prior code § 159.140)
A design of a subdivision shall provide, to the extent practical and feasible, for future passive or natural heating and cooling opportunities for individual lots within the subdivision.
A.
Examples of passive or natural heating opportunities in subdivision design include lot size and configuration to permit orientation of a structure in an east-west alignment for southern exposure.
B.
Examples of passive or natural cooling opportunities in subdivision design include lot size and configuration to permit orientation of a structure to take advantage of shade and prevailing breezes.
C.
In providing for future passive or natural heating or cooling opportunities in the design of a subdivision, consideration shall be given to local climate, parcel configuration and other design improvement requirements. Such provision shall not result in reducing allowable densities or the percentage of a lot which may be occupied by a building under applicable planning and zoning policies and regulations in force at the time of filing the tentative map.
D.
The requirements of this section shall not apply to condominium projects which consist of the subdivision of airspace in an existing building when no new structures are added.
E.
For purposes of this section, "feasible" means capable of being accomplished in a successful manner within a reasonable period of time, taking into account relevant economic, environmental, social and technological factors.
