A. 
The widths, alignments and geometric designs of streets and highways shall conform to the city standards and to the following requirements:
1. 
All streets, as far as practicable, shall relate to the alignment of the existing adjacent streets or their proper projection in the general conformity with the general plan for the city.
2. 
The proposed street plan shall give consideration to the future division of adjoining and undivided property.
3. 
All streets shall be designed to serve the proposed use of the abutting land.
4. 
On part-width boundary streets the required right-of-way shall not be less than thirty feet.
5. 
Additional right-of-way or easements shall be provided where necessary to accommodate roadway slopes and drainage facilities.
B. 
Special Street Design.
1. 
Design of streets shall make provisions for railroads, parkways, grade separations, prevailing geological conditions, local drainage facilities, hillside property and equestrian trails.
2. 
For lots in the L-2, LM, M, H, PD-x and SP-x zoning districts, the maximum cul-de-sac length shall be six hundred feet. For lots in all other zones, a cul-de-sac length up to one thousand three hundred twenty feet may be approved.
3. 
A dead-end street shall not exceed six hundred feet in length and shall only be permitted as an interim condition to facilitate the phasing of a tract map or parcel map. The fire marshal shall review and comment on all requests for dead end streets.
4. 
The planning commission may require greater street widths and improvements on streets serving multifamily residential, commercial or industrial divisions of land.
5. 
Where a proposed subdivision abuts or contains an existing or proposed urban arterial highway or freeway, the planning commission may require frontage streets or reverse frontage with nonaccess easements along the arterial highway or freeway or such other treatment as may be justified for the protection of residential properties from the nuisance and hazard of high volume traffic, and to preserve the function of the arterial highway or freeway.
C. 
Private streets may be used for only those streets serving property within the subdivision and which access by the public is controlled by the subdivision design by either posting or gating. Private streets may be used with the approval and consent of the planning commission when the planning commission finds that:
1. 
There is adequate provision for their construction and continued maintenance.
2. 
The welfare of the occupants of the development will be adequately served.
3. 
The public welfare will not be impaired.
D. 
The grades of highways, streets and alleys shall not be less than five-tenths percent and not greater than fifteen percent. The desirable grades are between five-tenths percent and six percent. Grades of less than five-tenths percent and greater than fifteen percent may be approved only when conclusive evidence shows that a lesser or steeper grade respectively is impractical. The high cost of excavating and/or importing borrow fill material, making the development of a particular parcel of ground uneconomical shall not be considered as conclusive evidence nor valid justification for a departure from the established minimum or maximum grade.
E. 
Street Alignment.
1. 
Curves in streets shall have as large a centerline radius as practical with a minimum length of curve of one hundred fifty feet. The desirable minimum-centerline radius for residential streets is five hundred feet. The minimum centerline radius for residential streets within comparatively level terrain shall be three hundred feet and within steep hillside terrain shall be one hundred fifty feet.
2. 
The minimum centerline radius for other types of streets shall be compatible with the street classification and anticipated usage.
F. 
Intersections.
1. 
All street intersections shall be as near right angles as possible, plus or minus five degrees, unless otherwise approved by the city engineer.
2. 
Street-to-street centerline offsets of less than two hundred fifty feet shall not be permitted, except in special design cases offsets of less than five feet may be used if approved by the city engineer.
3. 
A minimum curb return radius of twenty-five feet shall be provided at intersecting streets designated as collector roads or a lessor standard. A minimum curb return radius of thirty-five feet shall be provided when one or both of the intersecting streets is designated as a secondary highway or greater.
4. 
The property line return radius shall be so set as to maintain a uniform parkway width or provide a uniform transition into the intersecting parkway. The property line radius shall be designed so as not to reduce the parkway width below the city standard.
5. 
Frontage road connections providing access to a major or arterial highway shall incorporate a bulb or knuckle connection in conformance to city standards.
6. 
Median openings or crossovers between opposing lanes of a divided highway or street shall be located only at approved intersections at intervals of not less than five hundred feet.
G. 
Alleys.
1. 
Alleys shall be required in the rear of all lots used or intended to be used for business, commercial or industrial uses, unless adequate off-street parking areas and service loading and unloading areas to serve such properties are securely reserved for such use and are shown upon the map and approved by the city in the manner provided by this title.
2. 
Alleys shall be required in the rear of all lots fronting directly on a street designated as a secondary highway or greater unless determined through site plan review procedure that the requirement for alleys does not exist.
3. 
The minimum paved width for alleys shall be twenty-five feet except for residential applications where the minimum paved width shall be twenty feet.
4. 
A minimum curb return radius of five feet shall be provided at the alley and intersecting street.
5. 
Where practicable shall be "L" shaped or slightly turned to eliminate through traffic.
6. 
Where a dead-end alley is designed, an adequate turning area shall be provided to accommodate a truck having a thirty-five foot turning radius. It shall be such that the truck is able to turn around with only one backing movement. This turn-a-round shall be eliminated only under the circumstances of a previously adopted specific plan of record providing for the alley extension.
(Ord. 99-23 § 1)
A. 
All lots created in a division of land shall conform to the minimum requirements of the development code and the general plan as adopted by the city for the particular zoning district, use and classification in which the development is being constructed.
B. 
Lot Sizes.
1. 
All lots shall meet the area, frontage, width, depth and building setback requirements of the zoning district within which the lots are located; provided, however, that in its consideration of any land division, the planning commission or the city council may determine that a greater than minimum lot size is necessary:
a. 
For the proper protection of the public health, safety and general welfare;
b. 
To be consistent with the general pattern established in the vicinity;
c. 
To maintain the value of property in the vicinity; or
d. 
To provide sufficient pad area for buildings and usable open space.
2. 
When lots or parcels twice or more the required area or width are shown on a division of land, the planning commission may require such lots or parcels to be so established as to make practical a further division into allowable building sites, without injury to adjoining property.
3. 
Lot sizes and arrangement shall be compatible with lots in the surrounding area, subject to the preceding two provisions.
C. 
Side Lot Lines.
1. 
Sidelines of lots shall be at approximately right angles to the street lines, except where terrain or street design makes such lot lines impractical.
2. 
Side and rear lot lines shall be located along the top of slopes instead of at the toe or at intermediate locations.
D. 
Lot Frontage.
1. 
All lots shall have frontage upon a public or private street, which shall be open to and usable by vehicular traffic. The width of such streets shall be determined in accordance with this title and the development code.
2. 
Double frontage lots shall be avoided, except where essential to provide separation of residential development from traffic arteries, or where required by unusual or excessive topographic conditions. When double frontage lots are permitted, access rights shall be dedicated to the city along the street designated by the planning commission.
E. 
Wherever practicable, subdivisions of property abutting rights-of-way for freeways, expressways, railroads, transmission lines and flood control channels shall be so designed as to create lots which back up to the rights-of-way.
F. 
No lot shall be divided by a city, county, school district or other taxing agency boundary line.
G. 
Blocks.
1. 
Blocks shall not be less than two hundred fifty feet in length.
2. 
Blocks shall not be over two thousand seven hundred feet in length, except along major highways, or where topographical conditions or previous highway or street layouts require a different length.
(Ord. 99-23 § 1)
A. 
Any land division shall provide vehicular access to all homes within a land division for purposes of police and fire protection. The layout of the tract shall be such that blocks of thirty-five or more homes shall have access by two or more streets. Tract street layout showing only one street for vehicular ingress or egress to a large group of homes shall be cause for disapproval.
B. 
Access for lots not fronting on a public street (flag lots). When a land division is proposed to create any lot(s) other than one(s) fronting directly on a public street or highway, access shall be provided of a width not less than as specified below as being minimum width necessary to serve the maximum number of lots.

Required Improvement of Access.
a. 
Access Surfacing. Prior to final inspection for occupancy of any building or structure relocated, erected or constructed on any lot not fronting directly on a public street or highway, the full length of any required access shall be improved with concrete or asphaltic concrete surfacing, in accordance with city engineering standards and requirements, for a width as provided herein:
i. 
For access widths of twenty to twenty-nine feet; a surfaced width of not less than eighteen feet.
ii. 
For access widths of forty feet or more; a surfaced width of not less than twenty-four feet.
