Chapter 16.16 — DESIGN STANDARDS

All subdivision maps shall conform to any specific plans of streets, public areas, or other projects adopted by the council. There shall be conformance to the principles and standards of the general plan or elements thereof, and to the city's zoning regulations. In the absence of a master or general plan, the street system in a proposed subdivision shall relate to the area adjoining the subdivision.

(Ord. 384 §5(A), 1978)

Arterial streets shall conform to the standard specifications adopted by the council for subdivision improvements.

(Ord. 384 §5(B), 1978)

Collector streets shall conform to the standard specifications adopted by the council for subdivision improvements.

(Ord. 384 §5(C), 1978)

Local streets shall conform to the standard specifications adopted by the council for subdivision improvements. Cul-de-sac streets shall be not more than six hundred feet in length, measured from the centerline of the intersecting through street to the center of the cul-de-sac, and shall be terminated by a turnaround of not less than fifty-feet radius. Local streets shall be laid out so that their use by through traffic will be discouraged.

(Ord. 384 §5(D), 1978)

Along arterial streets or highways, a frontage street separated from the arterial street or highway by an adequate separation, when indicated by a master or precise plan, may be required for access to abutting private property and local streets.

(Ord. 384 §5(E), 1978)

Private streets shall only be permitted in planned unit developments.

(Ord. 384 §5(S), 1978)

Where a subdivision adjoins unsubdivided land, streets which may be necessary to assure the proper subdivision of the adjoining land shall be provided to the boundary line of the subdivision. A temporary turnaround of a fifty-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.

(Ord. 384 §5(Q), 1978)

A minimum centerline radius of at least five hundred feet shall be used on all arterial streets. Curves on local streets shall have minimum radii of two hundred thirty-five feet.

(Ord. 384 §5(F), 1978)

Street corner radii shall be twenty feet.

(Ord. 384 §5(G), 1978)

Street intersections shall be as near right angles as practicable.

(Ord. 384 §5(H), 1978)

Streets which are a continuation of streets in contiguous territory shall be so aligned as to assure that their centerlines will coincide. In cases where straight line continuations are not physically possible, such centerlines shall be continued by curves.

(Ord. 384 §5(I), 1978)

Alleys shall not normally be permitted in residential subdivisions, but may be permitted in nonresidential subdivisions.

(Ord. 384 §5(J), 1978)

A one-foot reserve strip shall be provided at the dead end of a stubbed street or at the edge of a partial width street and shall be offered for dedication to the city for future street purposes. Reserve strips shall be designated on the final map of the subdivision and shall be specifically referred to in the dedication certificate.

(Ord. 384 §5(R), 1978)

The subdivider may be required to dedicate and improve walkways through long blocks or to provide access to schools, parks or other public areas.

(Ord. 384 §5(T), 1978)

All lots shall have frontage on a public street, with the exception of lots located in planned unit developments of mobile home parks. Lots having double frontage should be avoided, but where unavoidable should have depths of not less than two hundred feet, except where access is limited to one street frontage only, or such double frontage is necessitated by topographical or other physical conditions.

(Ord. 384 §5(K), 1978)

No lot shall be divided by the boundary line of the city, a school district, or any other taxing district.

(Ord. 384 §5(L), 1978)

Blocks less than four hundred feet in length or more than eight hundred eighty feet in length may be cause for disapproval of the tentative map, but in no case shall blocks be longer than one thousand three hundred twenty feet in residential subdivisions. Block length is measured along the street centerline on which lots front; blocks which have no lots fronting thereon may be of lesser length.

(Ord. 384 §5(M), 1978)

Long blocks shall be desirable adjacent to arterial streets in order to reduce the number of intersections. The dimensions of such blocks measured at right angles to such arterial streets shall be sufficient to allow for two tiers of lots except when access from lots is limited to one street frontage only.

(Ord. 384 §5(N), 1978)

When property is designated for commercial or industrial use either in the general plan, an element thereof or the zoning regulations, the plan of the subdivision shall be appropriate for such uses. Streets shall have adequate capacity to handle the anticipated traffic which will utilize them. As far as practicable, streets shall be laid out so that there will be direct access to the commercial or industrial area from arterial or collector streets without utilizing local streets traversing residential areas. Lot areas and dimensions shall be adequate to accommodate the yard spaces, off-street parking facilities, and off-street loading facilities required by the zoning regulations.

(Ord. 384 §5(O), 1978)

Utility distribution facilities and lines, including but not limited to electric, communications, street lighting and cable television, shall be placed underground in any residential, commercial, or industrial subdivision. The subdivider shall be responsible for complying with the requirements of this chapter, and the subdivider shall make the necessary arrangements with the utility companies for the installation of and access to such facilities. For the purposes of this chapter, appurtenances and associated equipment such as, but not limited to, surface-mounted transformers, pedestal-mounted terminal boxes and meter cabinets may be placed aboveground. The provisions of this chapter shall not apply to utility distribution facilities and lines which do not provide services to the area being subdivided.

(Ord. 384 §5(P), 1978)

The city engineer shall review all subdivision proposals to assure that:

A.

All such proposals are consistent with the need to minimize flood damage;

B.

All public utilities and facilities, such as sewer, gas, electrical and water systems are located, elevated and constructed to minimize or eliminate flood damage; and

C.

Adequate drainage is provided so as to reduce exposure to flood hazards.

(Ord. 384 §5(U), 1978)

The subdivider shall, subject to riparian rights, dedicate right-of-way as may be approved by the city engineer for storm drainage purposes conforming substantially with the lines of any natural watercourse or channel, stream or creek that traverses the subdivision, or provide by dedication further and sufficient easements or construction or both, as approved by the city engineer, to dispose of surfacewater and stormwater. All flood control works to be constructed within selected floodlines shall be subject to approval

by the county flood control district. In those cases where all or a portion of a subdivision is located within a floodplain, and the subdivider is required to construct flood control works which will be dedicated to the city, the city may require that the subdivider enter into an agreement with the city for the construction of such flood control works. The city may require the subdivider to provide security to carry out his obligations under such an agreement, and the type and amount of such security and provisions for release of such security shall be set forth in the agreement.

(Ord. 384 §5(V), 1978)
