(A) The function, location, width, and grade of streets shall be considered in relation to existing and planned streets, to topographical conditions, to public convenience and safety, and to the proposed use of land to be served by the streets.
(B) The street system shall assure an adequate and safe traffic circulation system with intersection angles, grades, tangents, and curves appropriated for the traffic to be carried, considering the terrain.
(C) Off-set streets should be avoided.
(D) The angle of intersection between minor streets and major streets should not vary by more than 10 degrees from a right angle unless special intersection design is provided.
(E) Streets obviously in alignment with existing streets shall bear the names of the existing streets. All proposed street names should be checked to avoid duplication of other street names.
(F) If the subdivision abuts a present or proposed major arterial street, marginal interceptor streets running parallel to the arterial street may be required.
(G) Streets shall be interconnected and provide for continuation or appropriate extension to surrounding properties. Cul-de-sac streets shall be allowed only when one or more of the following conditions exist:
(1) Physical or topographic conditions make a street connection impracticable. Such conditions include but are not limited to freeways, railroads, steep slopes, wetlands, or other bodies of water where a connection could not reasonably be provided.
(2) Buildings or other existing development on adjacent lands physically precludes a connection now or in the future, considering the potential for redevelopment.
(3) Where street connection would violate provisions of leases, easements, covenants, restrictions or other agreements existing as of the date of adoption of the TSP which preclude a required street connection.
(4) Where cul-de-sacs are planned, multi-use paths connection the end of the cul-de-sac to other streets or neighborhood activity centers shall be provided if feasible.
(5) Cul-de-sac streets shall be as short as possible and should not exceed a length of 400 feet. A cul-de-sac shall terminate with a turn-around

(A) The width of streets and alleys shall be adequate to fulfill city standards as provided for in the Transportation System Plan (TSP). The standard cross-sections provide some flexibility in the right-of-way and paved width, depending on factors such as whether on-street parking and bike lanes are provided. Standards for streets and alleys are adopted in the TSP and incorporated into this section by reference:
- Table 1: Urban Arterial Cross Sections
- Table 2: Urban Collector Cross Sections
- Table 3: Urban Local Street Cross Sections
- Table 4: Rural Arterial/Collector/Local Road Cross Sections
(B) Where alleys are provided in residential blocks, a minimum width of 20 feet shall be required. Alleys are required in the rear of all business lots and shall be at least 25 feet wide. A five-foot cutoff shall be made at all acute angle alley intersections.

(A) Width requirements. Easements of at least six feet in width shall be provided on each side of all rear lot lines and along side lot lines, where necessary, for poles, wires, conduits, storm and sanitary sewers, gas, water or other mains. Easements of greater width may be required along or across lots where necessary for the extension of main sewers or other utilities or where both water and sewer lines are located in the same easement.
(B) Along streams. Whenever any stream or important surface drainage course is located in an area which is being subdivided, the subdivider shall provide an adequate easement along each side of the stream for the purpose of widening, deepening, sloping, improving or protecting the stream or for drainage, parkway or recreational use.
(C) For irrigation. Whenever any irrigation system is located and/or proposed to be created in an area which is being subdivided, the subdivider shall provide an adequate easement as approved by the Planning Commission and the Hermiston Irrigation District.
(Ord. 858, passed 4-14-75) Penalty, see 154.99
(A) In residential zones, block lengths shall not exceed 600 feet in length between intersecting through streets, except where topography or existing development creates conditions requiring longer blocks.
(B) Where block lengths exceed 600 feet, the Planning Commission may required a six to ten-foot wide paved bicycle/pedestrian access way through the block to enhance bicycle and pedestrian circulation by providing short, direct connections between destinations.
(Ord. 858, passed 4-14-75; Am. Ord. 2004, passed 12-13-99)) Penalty, see 154.99
(A) The lot arrangement and design shall be such that all lots will provide satisfactory and desirable building sites, properly related to topography and the character of surrounding development.
(B) All side lines of lots shall be at right angles to straight street lines and radial to curved street lines, except where a variation to this rule will provide a better street and lot layout. Lots with double frontage shall be avoided.
(C) The minimum width of residential lots shall be 60 feet at the building lines. No lot shall have a depth in excess of three times its width. Minimum sizes of lots shall conform to the standards established by the zoning code of the city for the zone in which the lots are located.
(D) Where corner lots rear upon lots facing the side street, the corner lots shall have extra width sufficient to permit the establishment of front building lines on both the front and side of the lots adjoining the streets.
(E) Corner lots at street intersections which, in the opinion of the Planning Commission, are likely to be dangerous to traffic movement shall have the corner of the lot cut off either by a chord or circular arc sufficient to allow a minimum of six feet between the curb line and the lot corner when and if the streets are curbed with the curb installed on a radius of 20 feet.

(A) The Planning Commission shall confer with the subdivider regarding the type and character of development that will be permitted in the subdivision and may agree with the subdivider as to certain minimum restrictions to be placed upon the property to prevent the construction of substandard buildings, control the type of structures or the use of the lots which, unless so controlled, would clearly depreciate the character and value of the proposed subdivision and of adjoining property. Deed restrictions or covenants should be included to provide for the proper protection and maintenance of the development in the future; provided, however, that the deed restrictions or covenants shall not contain (reversionary) clauses wherein any lot shall return to the subdivider because of violation thereon of the terms of the restrictions or covenants.
(B) Where the subdivision contains sewers, sewage treatment plants, water supply systems, park areas, streets, trees or other physical facilities necessary or desirable for the welfare of the area and which are of common use or benefit and are not or cannot be satisfactorily maintained by an existing public agency, provision shall be made by trust agreements made a part of the deed restrictions, acceptable to any agency having jurisdiction over the location and improvement of such facilities, for the proper and continuous maintenance and supervision of the facilities.
(Ord. 858, passed 4-14-75)
In subdividing property, consideration shall be given to suitable sites for schools, parks, playgrounds and other common areas for public use so as to conform to any recommendation of the City Comprehensive Plan. Any provision for schools, parks and playgrounds should be indicated on the preliminary plan in order that it may be determined when and in what manner such areas will be provided or acquired by the appropriate taxing agency.

Access spacing policies set forth in the City Transportation System Plan and the Oregon Highway Plan will apply to an proposals for new access or change of existing access.
