16.12.030 - Streets and highways.

A.

Freeways, shall conform to the standards of the state division of highways and department of public works, and where same are involved in any subdivision, they shall be subject to individual determination by the city.

Major highways shall be not less than one hundred feet wide.

C.

Secondary highways shall be not less than eighty feet wide.

D.

Collector and local streets shall be not less than sixty feet wide.

E.

Minor and cul-de-sac streets shall be not less than fifty feet wide, nor more than five hundred feet in length, except where special conditions might justify a lesser width or greater length. The radius at the terminus of the cul-de-sac should be not less than forty feet. Cul-de-sac and minor streets shall be subject to individual determination by the city. Stub streets or rights-of-way may be required to the edge of the subdivision.

F.

Special local streets, where railroads, parkways, grade separations, freeways and hills, or other dominant factors are involved, shall be subject to individual determination by the city.

G.

Curved major highways shall have a centerline radius of not less than one thousand feet.

H.

Curved secondary streets shall have a centerline radius of not less than five hundred feet. Lesser radii may be used if evidence indicates the above requirements are not practicable.

I.

Curves on other streets shall have a centerline radius of not less than two hundred feet. Lesser radii may be used if evidence indicates the above requirements are not practicable.

J.

Street corners shall have a radius of not less than fifteen feet or an equivalent angle.

K.

Street intersections shall be as near right angles as practicable. In no case shall the angle be less than forty-five degrees.

L.

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

M.

In areas where the general plan is silent and no other adopted city master plans exist, the layout of all improvements including roadways, curbs, parkways, dividing strips, sidewalks, sewer lines and water mains within the rights-of-way of all highways, streets, alleys and utility easements shall be in accordance with standards established by the city council, and, where no such standards have been adopted, the arrangements shall be subject to approval by the city engineer.

(Ord. No. 698, § 4, 10-14-15)

Improvements shall be installed at the cost of the applicant, and shall conform to grades and specifications established and approved by the city engineer.

(Ord. No. 698, § 4, 10-14-15)

A.

Alleys twenty feet wide shall be provided at the rear of all lots classified for and to be used for commercial or multiple-family purposes, but not including two-family use. If adequate off-street parking areas to serve such property are securely reserved for such purpose and are shown upon the final map and approved by the city in the manner provided in this title the requirements may be modified. Alleys elsewhere shall be optional with the city but, if offered, they shall be not less than twenty feet wide and shall be subject to approval by the city, both as to width and location. If a city adopted official plan indicates alleys which are not required by the above general rule, then the alleys thus shown shall be required.

B.

Alleys at the rear of business, industrial or unlimited multiple-residential property shall be subject to determination by the city as to design, location and possible increased width.

C.

Alleys shall be required at the rear of all property fronting directly upon any major highway.

D.

Where two alleys intercept or intersect, the corners shall be cut either on a ten-foot radius to which the lot boundaries are tangent, or on a straight line connecting points on both lot lines ten feet distant from the corner of the lot at the intersection of the alleys.

(Ord. No. 698, § 4, 10-14-15)

A.

Where alleys are not required, utility easements twelve feet in width shall be provided generally through the interior of the block and in approximately the location that would be occupied by an alley. If the easement parallels the boundary of a subdivision, the utility easement shall be eight feet in width.

B.

Overhead utilities should be located, where possible, through the interior of the block along either alleys or easements, as the case may be.

C.

Utility easements shall be located, where possible, through the interior of the block, but may be required alongside lot lines where necessary to provide for street lighting.

(Ord. No. 698, § 4, 10-14-15)

Along freeways or major highways, a service roadway separated from the main traffic roadway by an appropriate separation strip may be required, which service roadway will provide for access to abutting lands and to other public streets. Along major highways, an alley or alleys may be required in lieu of such service road or roads as a facility for serving lands marginal to such major highways. An alley may be required at the rear of all properties fronting directly upon any secondary highway.

(Ord. No. 698, § 4, 10-14-15)

Special areas for off-street parking of motor vehicles, offered for dedication or to be otherwise reserved for public use in connection with proposed business, industrial, unlimited multiple-residential, or institutional property, shall be subject to determination by the city as to size, location, shape and adequacy, and shall conform to the zoning code.

(Ord. No. 698, § 4, 10-14-15)

16.12.110 - Lots.

(Ord. No. 698, § 4, 10-14-15)

A.

Blocks less than three hundred thirty feet in length or more than nine hundred ninety feet in length may be grounds for disapproval, but in no case shall a block be longer than one thousand three hundred twenty feet.

B.

C.

Long blocks are desirable adjacent to main thoroughfares in order to reduce the number of intersections.

(Ord. No. 698, § 4, 10-14-15)
