Except where modified by the planning commission as provided in Chapter 19.48 of this code, or as allowed under Section 18.84.020 of this code, each map and subdivision shall conform with the standards set forth in this chapter.
(Prior code § 2-3.38)
Subdivisions shall result in lots which can be built upon. No subdivision shall create lots impractical to improvement due to steepness of terrain, location of watercourses, or other natural physical conditions.
(Prior code § 2-3.39)
All lots or parcels created by the subdivision of land shall have access to a public street of the standards as required in this chapter. Private streets will not be permitted.
(Prior code § 2-3.40)
A. 
The subdivision design shall conform to the pattern of thoroughfares designated in the general plan and to any future street rights-of-way designated by the city council. Unless so designated, all streets shall be classified by the planning commission at the time of approval of the tentative map, according to one of the classifications established in the following table. All streets and thoroughfares shall be plotted according to the minimum standards shown in the table and in Attachment No. 1 of the ordinance codified in this chapter. Narrower street widths may be allowed where the subdivider can demonstrate to the satisfaction of the planning commission that they are justified due to topography or the small number of lots served and the probable future traffic requirements. Increased widths may be required where streets serve high-density land uses or where probable traffic conditions warrant.

A cul-de-sac shall not have a greater length than 500 feet. See Attachment No. 1 of Or-dinance No. 358 for detailed street geometrics.
(Prior code § 2-3.41)
The developer of property abutting any existing or proposed street or thoroughfare shall be required to improve the street in accordance with the following schedules:
A. 
The developer shall grant to the city all required rights-of-way and easements necessary for the installation of streets, utilities and public facilities; provided, however, that in no case shall the developer's maximum obligation for the street or thoroughfare under consideration be deemed to exceed one-half of the total width required to widen the street or thoroughfare from the right-of-way width existing as of the date of adoption of Ordinance No. 358 (March 4, 1963). Should the required right-of-way exceed the developer's maximum obligation as set forth in this section, the city shall, after negotiating with the developer the cost factor of such excess right-of-way, make suitable arrangements relating to the excess right-of-way. Such arrangements may include payment by the city for the excess right-of-way, reduction of required pavement width on an estimated cost basis or other appropriate arrangements.
B. 
Curb, Gutter and Sidewalk. The developer shall construct all curb, gutter and sidewalk along all street frontages of property being developed and including streets with back-up lots, and the curb and gutter on both sides of the divider strip separating the frontage road from the thoroughfare.
C. 
Paving.
1. 
The developer shall construct pavement widths in conformance with the following:
a. 
Residential collector, minor residential, cul-de-sac—from the curb to the centerline of the street;
b. 
Frontage roads—the entire width between the curbs;
c. 
All other streets and thoroughfares adjacent to residential uses—20 feet maximum measured from the curb;
d. 
Industrial or commercial service street—from the curb to centerline of the street;
e. 
All other streets and thoroughfares adjacent to industrial uses—22 feet maximum measured from the curb;
f. 
All other streets and thoroughfares adjacent to commercial uses—32 feet maximum measured from the curb.
2. 
In applying the maximum obligations where the property to be developed abuts an existing public street, the developer shall be given credit for the width of any paving existing as of the date of adoption of Ordinance No. 358 (March 4, 1963); provided, the existing paving is adequate for the intended use in the opinion of the city engineer; and provided further, that the resultant paved roadway shall not create a drainage problem or traffic hazard, in the opinion of the city engineer. Where a new thoroughfare with frontage roads is created in a subdivision and the developer is not normally required to pave beyond the frontage road, the frontage road pavement shall be designed and constructed by the developer to carry the thoroughfare traffic on an interim basis until the thoroughfare portion of the road is completed, or the developer shall construct a sufficient width of the thoroughfare in order to carry the traffic.
3. 
When a new partial street is created on a boundary of a subdivision, the developer will be responsible for dedication and improvement as follows:
a. 
Dedication. One-half of the ultimate right-of-way or a width adequate to provide 30 feet of pavement measured from the face of the curb, whichever is greater;
b. 
Improvement. Permanent improvement to the centerline of the ultimate right-of-way plus sufficient temporary surfacing to create a total paved width of 30 feet measured from the face of the curb.
D. 
Other Improvements. The developer shall construct all other public improvements as required in Chapter 19.40 of this code.
(Prior code § 2-3.43)
The street pattern in the subdivision shall allow the most advantageous development of adjoining areas and the entire neighborhood or district. The following principles shall be observed:
A. 
Streets shall be continuous and in alignment with existing, planned or platted streets with which they are to connect. The centerlines of opposing streets entering upon a cross street and not in alignment shall be offset at least 125 feet on minor streets and 300 feet on all other streets.
B. 
Streets shall be extended to the boundary lines of the land to be subdivided, unless prevented by topography, cul-de-sac street pattern, or other physical conditions.
C. 
In the case of stub-end streets extending to the boundary of the property, a one-foot strip the width of the street right-of-way shall be deeded to the city at the end of the stub-end street, and improvements of the strip shall be suspended, pending the extension of the street into adjacent property. A temporary turnaround or a temporary connection to another street may be required of the subdivider, if considered necessary by the planning commission.
D. 
Streets shall intersect one another as nearly at right angles as good design permits.
E. 
Excessively long straight residential streets, conducive to high speed traffic shall be prohibited. Minor residential streets and alleys, as defined in Section 19.36.050, shall not be utilized unless recommended by the review board and approved by the planning commission.
F. 
Alleys shall not be permitted in residential subdivisions, but may be required in nonresidential subdivisions.
G. 
Where cul-de-sacs are planned, pedestrian and bicycle paths connecting the end of the cul-de-sac to other streets, paths, school routes, or neighborhood activity centers shall be provided unless infeasible in the determination of the community development director or designee.
(Prior code § 2-3.43; Ord. 2095 § 2, 2014)
Subdivision design adjacent to thoroughfares shall conform to the general plan, as determined by the planning commission. The following principles shall be observed:
A. 
Street design shall make adjacent residential lots desirable by cushioning the impact of heavy traffic and shall minimize cross traffic on thoroughfares.
B. 
Intersecting streets along thoroughfares shall be restricted. Wherever practicable, such intersections shall be spaced not less than 1,320 feet on center. The planning commission may, at the time of approval of the tentative map, require sufficient flaring of the rights-of-way of thoroughfares at intersections to allow the construction of traffic stacking lanes as designated by the city engineer.
C. 
Public service easements when required in front yards in residential developments may be used for either landscaping or utility purposes, or both, upon approval of the planning commission.
D. 
Frontage roads shall enter thoroughfares by bulb-type intersections capable of stacking at least four cars between the frontage road and the thoroughfare.
E. 
Where frontage roads are not required, residential lots adjacent to the thoroughfares normally will be required to be served by a residential collector street paralleling the thoroughfare at a lot depth of not less than 120 feet therefrom, or by a series of cul-de-sacs or loop streets extending towards the thoroughfare from a collector street no more than 600 feet therefrom. In such cases a wall or fence of a design approved by the planning commission shall be required within the right-of-way at the rear of properties adjacent to the thoroughfare. Permanent landscaping subject to the approval of the planning commission shall be installed between the fence and the thoroughfare curb.
F. 
When the rear of any lot borders any thoroughfare, the city may require the subdivider to execute and deliver to the city an instrument, deemed sufficient by the city attorney, prohibiting the right of ingress and egress from the thoroughfare to the lot.
(Prior code § 2-3.44)
Grades, curves and sight distances shall be subject to approval by the city engineer, to insure proper drainage or safety for vehicles and pedestrians. The following principles and minimum standards shall be observed:
A. 
Grades of streets shall not be less than three-tenths of one percent, nor greater than 15 percent, except as modified by Section 19.36.140 of this chapter.
B. 
At street intersections, property line and curb corners shall be rounded by arcs, such that the curb radius shall be not less than 20 feet for streets up to collector in capacity. For intersections with arterials, the radius shall be required by the city engineer.
C. 
The radii of curvature shall not normally be less than 400 feet on the centerline of thoroughfares and less than 100 feet on the centerline of collector or minor residential streets.
(Prior code § 2-3.45)
The following principles and standards shall apply to the design and installation of curbs, sidewalks and pedestrian ways:
A. 
Vertical curbs and gutters shall be required in all subdivisions.
B. 
Sidewalks shall be required on both sides of the street in any subdivision or portion thereof having any lot with an area of less than one-half acre.
C. 
The requirement for sidewalks may be omitted, at the discretion of the planning commission, in a subdivision or section thereof in which all lots have an area of one-half acre or more.
D. 
When required for access to schools, playgrounds, shopping centers, transportation facilities, other community facilities, or for unusually long blocks, the planning commission may require pedestrian ways not less than 10 feet in width.
E. 
Sidewalks shall be located within the street right-of-way at the dedicated boundary of the street.
(Prior code § 2-3.46)
Street trees, in an amount as determined by the city engineer, shall be provided by the subdivider in all subdivisions on both sides of the street, either within the street right-of-way or within a dedicated public service easement, not less than eight feet wide adjacent to the street. Street trees shall be selected, installed and maintained in accordance with city ordinances or regulations.
(Prior code § 2-3.47)
Public service easements, not less than 10 feet in width, shall be provided within the subdivision where required for public utility purposes. Modification of the easement width requirement may be made only when approved by both the planning commission and public utility concerned.
(Prior code § 2-3.49)
Blocks shall have sufficient width for an ultimate layout of two tiers of lots therein of the size required by the provisions of this chapter or Title 18 of this code, unless the surrounding layout or lines of ownership justify or require a variation from this requirement.
(Prior code § 2-3.50)
Blocks shall not normally exceed 2,000 feet in length between street lines, except in hillside developments or where subdivisions containing parcels of one-half acre or larger justify or require a variation from this requirement. In any block over 900 feet in length, the planning commission may require that a paved and adequately identified crosswalk or pedestrian way, not less than 10 feet in width, be provided near the center and entirely across such block.
(Prior code § 2-4.00)
The size, shape and orientation of lots shall be appropriate to the location of the proposed subdivision and to the type of development contemplated. The following principles and standards shall be observed:
A. 
The minimum area and dimensions of all lots shall conform to the requirements of Title 18 of this code for the district in which the subdivision of land is located.
B. 
The side line of all lots, so far as possible, shall be at right angles to the street which the lot faces, or approximately radial to the center of curvature, if such street is curved. Side lines of lots shall be approximately radial to the center of curvature of a cul-de-sac on which the lot faces.
C. 
No lot shall have a street frontage less than 35 feet.
D. 
No lot shall have a width less than 45 feet at the building setback line.
E. 
Corner lots for residential use shall be platted wider than interior lots in order to permit conformance with the required street side yard requirements of Title 18 of this code.
F. 
No lot shall have a depth of less than 100 feet. Where the rear of a lot is adjacent to a playground, shopping center, industrial tract or other similar nonresidential use, or to the right-of-way of a freeway, railroad or thoroughfare, the depth shall be increased to a minimum of 120 feet.
G. 
No lot shall be divided by a city boundary line.
H. 
A lot depth in excess of twice the width shall be avoided whenever possible, and a lot depth in excess of three times the width shall not be permitted.
I. 
No remnants of property shall be left in the subdivision which do not conform to lot requirements or are not required for a private, public utility or other public purpose.
(Prior code § 2-4.01)
The subdivider shall reserve sites, appropriate in area and location, for necessary and desirable residential facilities such as public schools, parks and playgrounds and shopping centers. Such sites shall be located in accordance with the principles and standards of this chapter, Title 18, the general plan, and annexation policies of the city. If not dedicated to the public by the subdivider, such sites shall be reserved by the subdivider for a period of not less than one year pending purchase.
(Prior code § 2-4.03)
The neighborhood facilities needed shall be determined on the basis of the estimated number of families in the area to be served by the facilities.
(Prior code § 2-4.04)
Service areas determining the need for residential facilities at the district or community level are subject to special determination, based on the general plan. The planning neighborhood will normally provide the basis for estimating the number of families to be served by facilities at the local level. A planning neighborhood may be identified by the following characteristics:
A. 
It is bounded by major thoroughfares or other substantial land use or natural barriers to pedestrian traffic.
B. 
It is usually not over a mile in extent in any direction.
C. 
It contains a minimum of 500 families.
(Prior code § 2-4.05)
The following principles and standards are intended to serve as a general guide in determining the residential facilities for which sites normally will be required:
A. 
An elementary school site of approximately 10 acres will be required for each 600 families, more or less. Such school site shall be central to the population to be served and shall not be located on a major thoroughfare.
B. 
Whenever possible, playground and neighborhood recreation areas shall be developed in conjunction with elementary school sites. A park site, if required, shall not normally be less than five acres in area, and such sites shall specifically include areas with natural advantages for park development.
C. 
A site of approximately four to six acres including off-street parking and landscaping will normally be required for a local shopping center to serve a population of about 1,500 to 2,000 families.
(Prior code § 2-4.06)
The street and lot layout of a nonresidential subdivision shall be appropriate to the land use for which the subdivision is proposed, and shall conform to the proposed land use and standards established in the general plan and required in Title 18 of this code.
(Prior code § 2-4.07)
Nonresidential subdivisions shall include industrial tracts, and may include neighborhood, community and central business district commercial tracts.
(Prior code § 2-4.08)
The subdivider shall demonstrate to the satisfaction of the planning commission that the street parcel and block pattern proposed is specifically adapted to the uses anticipated and takes into account other uses in the vicinity. The following principles and standards shall be observed:
A. 
Proposed industrial parcels shall be suitable in area and dimensions to the types of industrial development anticipated.
B. 
Street rights-of-way and pavement shall be adequate to accommodate the type and volume of traffic anticipated to be generated thereon.
C. 
Special requirements may be imposed by the city with respect to street, curb, gutter and sidewalk design and construction.
D. 
Special requirements may be imposed by the city with respect to the installation of public utilities, including water, sewer and stormwater drainage.
E. 
Residential areas shall be protected from potential nuisance by including extra depth in parcels backing up on existing or potential residential development and providing a permanently landscaped buffer strip when necessary.
F. 
Streets carrying nonresidential traffic shall not normally be extended to the boundaries of adjacent existing or potential residential areas or connected to streets intended for predominantly residential traffic.
G. 
Subdivisions for proposed commercial development shall specifically designate all areas proposed for vehicular circulation and parking, for pedestrian circulation, and for buffer strips and other landscaping.
(Prior code § 2-4.09)
A. 
Nothing contained in this chapter shall be construed as precluding the approval of planned unit developments as provided in Title 18 of this code. A tentative map, which may also constitute the exhibit that must accompany any necessary zoning action, shall be prepared in the form specified in this title, with the additions or revisions to the normal form which may be deemed necessary by the review board. Each tentative map shall designate the type of planned unit which is contemplated in accordance with one of the following designations:
1. 
Planned Unit Development—Type I. A Type I planned unit development is one which may be considered a planned unit in keeping with the spirit and intent of the zoning ordinance, but one wherein the outstanding characteristic, when compared to a conventional subdivision, is merely the mixture of various land uses and densities within the boundaries of the subdivision. It is not intended that a Type I planned unit development will be in conflict with this title, and consideration of any departure from the conventional must include adherence to the applicable provisions of Title 18 and Chapter 19.32 of this title.
2. 
Planned Unit Development—Type II. It is intended that a Type II planned unit development be a more radical departure from the conventional subdivision. While the burden of the proposal for a Type II planned unit development is placed upon the subdivider in terms of establishing new concepts, it is suggested that he or she make every effort to coordinate closely the development of a proposal with the city staff and the review board prior to the filing of a tentative map, in order that such map may be basically in agreement with the views of the city prior to the preparation of a tentative map to the detail required in this title. In order to provide examples of, but not limit the possible methods of varying from the norm in a Type II development, the following list is intended to represent items which may vary in context from the requirements regarding these items as stated in this chapter:
a. 
Lot dimensions and areas;
b. 
Street widths;
c. 
Sidewalk requirements;
d. 
Block lengths;
e. 
Front, side and rear yard requirements;
f. 
Access to public streets;
g. 
Basic concepts of street pattern and design.
B. 
The basic criteria which will govern the applicability of the Type I and Type II unit development provisions of this chapter in residential areas is that of average population density. The average population density of a planned unit development will be no higher than that which could be obtained under the general plan and the specific zoning of the property. However, this density may be increased in certain portions of a subdivision, provided there are sufficient areas utilized for parks and other open spaces, large lots and other amenities, in order to allow the total development to conform to the average density requirement. Consideration of any departure from the requirements of this chapter regarding Type II planned unit developments must include adherence to the applicable provisions of Title 18 and Chapter 19.32 of this title.
