17.05.390 Subdivision design.

A. The design of subdivisions shall conform with the requirements of any official control relating to land use, which may be adopted to implement the Columbia County comprehensive plan or any element thereof or any other official plan. In accordance with the goals and policies of the comprehensive plan, subdivisions are encouraged in urban areas where adequate public facilities and services exist or can be provided in an efficient manner. Furthermore, subdivisions are encouraged where their design does not contribute to the inappropriate conversion of undeveloped land into sprawling, low-density development; provided, that in the event of a discrepancy among standards and requirements, the responsible department may exercise professional judgement to determine which standard or requirement shall control. The design, shape, size and orientation of the subdivision shall be appropriate to the use for which the divisions of land are intended and to the character of the area in which they are located. Tracts may be required to be segregated or restrictions required to be included in the subdivision, for sanitation, utilities, steep slopes, access, slide hazards, water supply, poor drainage, or flood hazard reasons or for other unique conditions or features which may warrant protection of the public interest.

B. If there is not adequate existing public access, the county shall require the design and installation of new public access in accordance with the county’s design and improvement standards and general plat requirements which the county may impose on the development. [Ord. 2008-04 § 2; Ord. 75-04 § 36A.]

17.05.400 Design – Conformance to comprehensive plan and zoning.

All subdivisions shall conform to the Columbia County comprehensive plan and all zoning regulations in effect at the time any preliminary plat of a subdivision is submitted for approval.

All roads, bridges, drains, culverts and related structures and facilities shall be constructed in accordance with current standards promulgated by the board and in effect at the time of construction. [Ord. 75-04 § 39.]

17.05.430 Design – 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 for two tiers of lots unless the topography or other factors dictate the use of one tier of reverse frontage lots or unless the planning commission approves the design of irregularly shaped blocks indented by cul-de-sacs within a particular subdivision. [Ord. 75-04 § 40.]

17.05.440 Design – Lot access.

A. Every lot shall be provided with satisfactory access by a public road connecting to an existing public road, or by an easement which is permanent and inseparable from the lot served.

B. No more than two lots shall be served by an easement which is the exclusive means of access to these lots.

C. Lots adjacent to a road which has been designated an arterial by the board shall be provided with access other than the arterial, unless the board grants specific exemption to this requirement.

D. The plat of a subdivision containing lots adjacent to a designated arterial shall not be approved unless the plat recites a waiver of the right of direct access to the arterial, or the board grants specific exemptions to this requirement. [Ord. 75-04 § 41.]

17.05.450 Design – Lot line angles.

Where practicable, side lot lines shall be straight lines running at or near right angles to the road upon which the lots front. Side lot lines on curved roads should run at or near radially to the curve. [Ord. 75-04 § 42.]

17.05.460 Design – Drainage and storm sewer easements.

When deemed necessary by the board, easements for drainage channels and ways shall be of sufficient width to assure that the same may be maintained and improved. Easements for storm sewers shall be provided and shall be of sufficient width and proper location to permit future installation. [Ord. 75-04 § 43.]

17.05.470 Design – Utility easements.

Easements for electric, telephone, water, gas and similar utilities shall be of sufficient width to assure future maintenance. When initial installation of such facilities will be other than underground, easements for the same shall be sufficiently wide and so located as to permit future installation of underground utilities. [Ord. 75-04 § 44.]

17.05.480 Design – Underground utility installation.

Subdivisions shall provide underground utility lines, including but not limited to those for electricity, communications and street lighting. Where topography, soil, or other conditions make underground installation impracticable and the planning commission so finds upon written evidence presented by the supplier of such utilities it may waive requirement for underground utilities. [Ord. 75-04 § 45.]

17.05.490 Development of improvements – Curbs – Sidewalks and storm sewers.

All roads required within a subdivision shall be constructed with curbs and gutters or rolled curbs, underground storm sewers and sidewalks, when recognized by existing standards and deemed necessary by the board. [Ord. 75-04 § 46.]

17.05.500 Development of improvements – Water supply system.

When a proposed subdivision is to be serviced by a public water supply system and such system appurtenances, such system shall be provided by the subdivider. If there is no existing or accessible public water supply system, the subdivider may be required to install a water supply system for the common use of the lots within the subdivision. Individual wells may be permitted in accordance with the requirements of the county health department. When wells, springs and streams are to be the water supply source, a water right must also be obtained from the State Department of Ecology. All water supply systems must be approved by the county health department. [Ord. 75-04 § 47.]

17.05.510 Development of improvements – Sanitary sewer systems.

When a proposed subdivision is to be serviced by a public sanitary sewerage system, sanitary sewers and other required appurtenances thereto shall be proved by the subdivider. If there is no existing or accessible public sewer system, a sewer system for the common use of the lot owners may be required to be provided by the subdivider. Where it is determined in the judgment of the board that a subdivision cannot be feasibly connected with an existing public or private sewer system or that a public or private sewer system cannot be provided for the subdivision itself, then an approved disposal system may be required which shall comply with the requirements of the county health department. [Ord. 75-04 § 48.]

17.05.520 Development of improvements – Solid waste disposal requirements.

The subdivider shall be required to make provisions for adequate solid waste disposal services including transportation to a disposal site approved by the county health department. [Ord. 75-04 § 49.]

17.05.530 Survey – Preparation of plats.

The survey of every proposed subdivision and the preparation of preliminary and final plats thereof shall be made by or under the supervision of a registered land surveyor who shall certify on the plat that it is a true and correct representation of the lands actually surveyed. All surveys shall conform to standard practices and principles for land surveying. [Ord. 75-04 § 50.]

17.05.570 Survey – Permanent control monuments in roads.

Permanent control monuments within the streets shall be set after the roads are graded. In the event a final plat is approved before roads are graded the surety deposited to secure grading shall be sufficient to include the costs estimated by the county engineer of setting such monuments. [Ord. 75-04 § 54.]

17.05.580 Survey – Lot corners.

Every corner shall be marked by a two-inch galvanized iron pipe or approved equivalent permanently driven into the ground. [Ord. 75-04 § 55.]

17.05.590 Survey – Property contiguous to water.

If any land in a subdivision is contiguous to a body of water, a meander line shall be established along the shore at a safe distance back from the ordinary high water mark. Property lying beyond the meander line shall be defined by distances along the side property lines extended from the meander line. If the thread of a stream lies within a subdivision or forms the boundary of a subdivision, such thread shall be defined by bearings and distances as it exists at the time of the survey. [Ord. 75-04 § 56.]
