16.36.020 Topographical hazards—Protective improvements.
Land having topographical conditions hazardous to the safety or general welfare of persons or property in or near a proposed subdivision, shall not be subdivided unless the construction of protective improvements will eliminate the hazards or unless land subject to the hazard is reserved for those uses which will not expose persons or property to the hazard. Protective improvements and restrictions on uses shall be clearly noted on the final plat. (Ord. 67 § 29, 1972)
16.36.030 Streets and alleys.
A. All subdivisions shall be served by one or more public streets providing adequate ingress and egress to and from the subdivision.

Unless warranted by special physical circumstances, streets serving lots on two sides shall be at least sixty feet wide.
C. Street intersections shall be as nearly at right angles as practicable and in no event shall be less than thirty degrees.
D. Cul-de-sacs shall be designed so as to provide a circular turnaround at the closed end which has a minimum radius of forty feet and a minimum roadway radius of twenty-eight feet. A wye may be authorized by the commission in lieu of the turnaround under certain circumstances. Cul-de-sac streets shall not exceed four hundred fifty feet in length and shall be at least forty feet wide.
E. Street networks shall provide ready access for fire and other emergency vehicles and equipment, and routes of escape for inhabitants.

(Ord. 67 § 30, 1972)
16.36.040 Blocks.
Blocks shall be so designed as to assure traffic safety and ease of traffic control and circulation. Blocks shall be wide enough to allow two tiers of lots unless the topography or other factors dictate the use of one tier of reverse frontage through lots or unless the commission approves the design of irregularly shaped blocks indented by cul-de-sacs within a particular subdivision. Blocks shall be identified by letters or numbers. (Ord. 67 § 31, 1972)
16.36.050 Lots.

C. Lots shall be numbered with reference to blocks.
(Ord. 67 § 32, 1972)
16.36.060 Through lots.
No residential lot shall have street frontage along two opposite boundaries unless topographical features or the need to provide separation of lots from arterials, railways, commercial activities, or industrial activities justify designing of reverse frontage lots. (Ord. 67 § 33, 1972)
16.36.070 Lot line angles.
Where practicable, side lot lines shall be straight lines running at or near right angles to the street upon which the lot is fronted. Side lot lines on curved roads shall run at or near radially to the curve. (Ord. 67 § 34, 1972)
