16.20.010 Blocks and lots:

Blocks shall not be longer than one thousand two hundred feet between intersecting street lines, except on arterial streets and expressways where longer blocks may be required. Lots with frontage on more than one street will not be permitted, except corner lots, unless topographic conditions warrant and then only upon approval of the planning commission and when access rights are released on one street. A one-foot non-access strip, in addition to other easements, shall be dedicated to the city for the installation of a permanent wall or fence when required by the planning commission. (Ord. 98 §8(1), 1966).

16.20.020 Walkways.

Improved walkways not less than ten feet in width may be required through blocks more than nine hundred feet in length and through other blocks where necessary to provide access to schools, parks and scenic easements. (Ord. 98 §8(2), 1966).

16.20.030 Easements.

Easements not less than five feet wide shall be required on each side of all lots and ten feet wide at the rear of all lots where necessary for poles, wires, drainage and water mains, or other utilities. The city engineer may allow reduction of the width when in his opinion, and in the opinion of the serving utility, a lesser width is justified. All pole lines shall be located in the rear except when otherwise approved by the planning commission. (Ord. 98 §8(3), 1966).

16.20.040 Watercourses and storm drains:

Watercourses shall be shown as easements, and storm drains shall be placed in easements when public right-of-way is not available or adequate. The planning commission or city engineer may require watercourses to be placed entirely in underground conduits or adequately fenced or otherwise improved. (Ord. 98 §8(4),1966).

16.20.050 Monuments.

A.    Durable metal monuments consisting of iron pipes approved by the city engineer shall be installed or referenced to the following locations:

1.    Boundary corners,

2.    At intervals of not more than five hundred feet along boundary lines,

3.    At the beginning and ending of property line curves or P.I. at discretion of city engineer,

4.    Lot corners, and in addition, a lead and tack shall be set in the sidewalk on the prolongation of the side lot lines. Standard monuments shall be placed along the centerlines or public streets and alleys as follows: all intersections, all P.I.’s or beginning and ending of curves.

B.    All lots shall abut on a street unless approved as a "deep lot" subdivision by the planning conunission, under policies adopted by said planning commission.

C.    Building setbacks shall be required at least as great as the applicable zoning requirements.

D.    The size and shape of lots shall conform to any zoning regulations affecting the land to be subdivided. In no case shall the lot depth be greater than three times the average width. (Ord. 98 §8(5)--(8), 1966).

16.20.060 Roads and streets.

A.    Existing streets shall be continued as required by the planning commission.

B.    Street stubs shall be required to adjacent unsubdivided property where, in the opinion of the planning commission, they are necessary. A satisfactory temporary turnaround may be required.

C.    Streets shall intersect at as near right angles as is practicable. Radius of curvature, where the property lines intersect, shall be a minimum of ten feet, except at arterial streets and expressways it shall be twenty feet.

D.    "T" or three-way intersections are preferable to four-way intersections. The centerlines of opposing streets intersecting a common street shall be offset not less than two hundred feet.

E.    Reserve strips, where required to control access over certain lot lines or over the ends of street stubs, shall be dedicated to the city.

F.    Alleys shall be constructed in industrial, commercial and in multiple-family areas where necessary to control access to expressways and arterial streets.

G.    Cul-de-sac streets shall have the following limiting dimensions:

1.    Forty feet minimum radius to curb, at turnaround,

2.    Fifty feet minimum radius to property line at turnaround,

3.    Five hundred feet maximum length, from intersecting street line to bulb radius point,

4.    Longer cul-de-sac may be allowed to serve twelve or less lots.

H.    Names for proposed new streets shall be assigned by the planning department and shown on the tentative map.

I.    Streets, rights-of-way and easements in any subdivision shall be offered for dedication. The city may, at its option, accept or reject any such offer. In the event any street shown on the subdivision map is not offered or accepted for dedication, the certificate may contain a statement to this effect. If such statement appears on the map and the map is approved by the city council, the use of any such public street shall be permissive only.

J.    Streets shall conform, as to alignment and width, to the official master plan for streets and highways of the city.

K.    Where a subdivision abuts or contains any existing or proposed state highway or freeway, arterial street, or railroad right-of-way, the planning commission shall require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, deep lots with rear service alleys, or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.

L.    Streets within a new subdivision shall connect to a City street, County maintained road, or State highway. Where an off-site connection is necessary to provide access to such street, road or highway, the subdivider shall acquire the right of way and construct the improvements required. (Ord. 180 §4, 1975: Ord. 98 §8(9), 1966).
