(Ord. 550 (part), 1994).
16.21.050 - Street patterns. ¶
The street pattern in the subdivision shall be in general conformity with a plan for the most advantageous development of adjoining areas and the entire neighborhood or district. The following principles shall be observed:
A.
Where appropriate to the design, proposed streets shall be contiguous and in alignment with existing planned or platted streets with which they are to connect.
B.
When required by the department of public works, proposed streets shall be extended to the boundary line of the land to be subdivided. A "No Access Rights" certificate shall be shown on the final map where
required by the public works department.

D.
No cul-de-sac shall exceed four hundred feet in length from the center of the turnaround to the centerline of the intersecting street unless approved as a special condition by the planning commission.

(Ord. 550 (part), 1994).
16.21.060 - Design adjacent to arterials. ¶
Subdivision design adjacent to major streets or highways shall be as determined by the planning commission.
A.
Street Design. Street design shall have the purpose of making adjacent lots, if for residential use, desirable for such use by cushioning the impact of heavy traffic and of minimizing the interference with traffic on such arterials.
B.
Intersecting Streets. The number of intersecting streets along arterials shall be held to a minimum.
C.
Bordering Highways. When the rear or side lines of any lots border a state highway or major street, the subdivider may be required to execute and deliver to the city an instrument prohibiting the right of ingress and egress to such lots across the side lines of such highways.
D.
Service Roads; Off-Street Parking. When lots proposed for commercial or industrial uses front on any major or secondary street or highway, the subdivider may be required to dedicate and improve a parallel service road to provide ingress and egress to and from such lots. When any lots proposed for residential use front on a state highway or a major street, the subdivider may be required to dedicate and improve a frontage service road at the front of such lots or to back lots to the highway or major streets.
E.
Additional Parking Areas. In addition to the requirements for a service road, the planning commission requires adequate off-street parking areas for all lots.
(Ord. 550 (part), 1994).
16.21.070 - Street names. ¶

(Ord. 550 (part), 1994).
16.21.110 - Utilities and easements. ¶
A.
Easements for public utilities shall be provided and shall not be less than ten feet in width, direct and continuous from block to block, or six feet on each side or rear lot line and side lines where necessary. When an easement on only one side of lot lines is required, it shall have a minimum width of twelve feet.
Easements of greater width will be required along natural water-courses, conforming substantially to the lines of such channels or such channels realigned.
B.
All utility distribution facilities shall be placed underground except as hereinafter provided in this title.
(Ord. 550 (part), 1994).
16.21.120 - Watercourses. ¶
The subdivider shall dedicate right-of-way for storm drainage conforming substantially with the lines of any natural watercourse that traverses the subdivision, or at the option of the planning commission, the subdivider shall provide by dedication further and sufficient easements or constructions or both, to dispose of such surface and stormwater.
(Ord. 550 (part), 1994).
16.21.130 - Block standards. ¶
The major dimensions of a block shall not exceed six hundred sixty feet (four hundred feet is preferred) in length or less than two hundred eighty feet (three hundred twenty feet is preferred) in length between street centerlines unless modified in accordance with the provisions of Chapter 16.24, entitled "Public Improvements."
(Ord. 550 (part), 1994).
16.21.135 - Residential subdivision construction requirements.
A.
It is the policy of the city to prevent construction of two houses with substantially identical exterior appearance within sight of each other. To implement this policy, the planning commission and/or city council shall establish reasonable standards to evaluate the exterior appearance of proposed houses.
B.
All building plans for new residential buildings must be reviewed by the planning department. Where more than one dwelling unit is being constructed as part of a new subdivision in which the units proposed will have similar floor plans and exterior elevations, each building shall be reviewed by the appropriate site development review committee. Unusual or controversial building proposals shall be referred to the planning commission for review. Conventional single-family or duplex buildings proposed to be constructed on individual existing lots may be reviewed and approved by the planning staff.
C.
To ensure compliance with this section, no building permit may be issued without a certification from the planning department that the proposed building plan has been reviewed and approved in accordance with this section.
(Ord. 550 (part), 1994).
16.21.140 - Nonresidential subdivisions.
A.
Conformance to General Plan. 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 zoning laws of the city.
B.
Types of Nonresidential Subdivisions. Nonresidential subdivisions shall include industrial tracts and may include commercial tracts.
C.
Principles and Standards. In addition to the principles and standards in this title which are appropriate to the planning of all subdivisions, the subdivider shall demonstrate to the satisfaction of the planning commission that the zoning and 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:
1.
Proposed industrial parcels shall be suitable in area and dimensions to the types of industrial development anticipated.
2.
Street rights-of-way and pavement shall be adequate to accommodate the type and volume of traffic anticipated to be generated thereon.
3.
Special requirements may be imposed by the city with respect to street, curb and gutter, and sidewalk design and construction.
4.
Special requirements may be imposed by the city with respect to the installation of public utilities, including electric, water, sewer, fire protection and storm drainage.
Every effort shall be made to protect adjacent residential areas from potential nuisance from the proposed nonresidential subdivisions, including the provisions of extra depth in parcels backing upon existing or potential residential development and provisions for a permanent landscape buffer strip when necessary.
6.
Streets carrying nonresidential traffic, especially truck traffic, shall not normally be extended to the boundaries of adjacent existing or potential residential areas, or connected to streets extended for predominantly residential traffic.
