16.28.030 Nonaccess and planting strips.

When the rear of any lot borders any major or secondary street, highway or parkway, the subdivider may be required to execute and deliver to the city an instrument, deemed sufficient by the city attorney, prohibiting the right of ingress and egress to the rear of such lots across the side lines of such streets or highways.

Where a parcel is subdivided into lots of one acre or more, the city council may require that the blocks shall be of such size and shape and be so divided into lots as to provide for the extension and opening of streets and alleys at such intervals as will permit a subsequent division of any parcel into lots of normal size. (Ord. 72 § 20, 1973)

16.28.070 Easements.

A. The subdivider shall grant easements not less than 10 feet in width for public utility, sanitary sewer and drainage purposes wherever necessary; provided, that easements of lesser width may be allowed with concurrence of public utilities and the director of public works the easements may be accomplished by easements of lesser width; and provided further, that in such determination the director of public works shall prescribe the width of such easements. Easements for overhead wire lines shall be provided at the rear of all lots, except where alleys are available, and in contiguous locations to permit of anchorage, line continuity, ingress and egress. Easements shall be dedicated for the purpose of installing utilities, planting strips and for such other public purposes as may be ordered or directed by the city council.

B. The subdivider shall submit a layout showing easements proposed for public utilities to the public utility servicing the subdivision. Prior to approval of the final map the subdivider shall obtain a letter from the public utility stating that the easements are adequate. A copy of the letter or letters shall be filed with the director of public works. (Ord. 72 § 21, 1973)

In unclassified districts, the city council shall specify the size and shape of all lots.

B. The side lines of all lots, so far as possible, shall be at right angles to the street which the lot faces, or radial or approximately radial, if the street is curved.

C. Front building setback lines shall be indicated by “dotted” lines on the subdivision map, as required by the city council.
