17.30.010 Purpose.

The city’s comprehensive plan sets forth the requirements for providing adequate transportation and utility systems to serve the community’s present and future needs. Land development without adequate transportation and utility systems will adversely affect the overall economic growth of the city and cause undue damage to the public health and welfare of its citizens. Consequently, the city finds that it is in the public interest to require land development to meet the following improvement requirements. (Ord. 974 § 4 (Exh. A.2 § 601), 1998)

17.30.020 Authority.

A. The public works superintendent is hereby given the authority to develop standard forms, including but not limited to deeds, easements, interim access agreements, escrow agreements, street improvement agreements, subdivision compliance agreements and agreements to dedicate right-of-way, to include the contents and warranties when they are submitted, and the procedure for implementation necessary to carry out the purpose of this chapter.

B. Any easements submitted on a final plat or on a separate easement form shall be subject to the requirements of this chapter. (Ord. 974 § 4 (Exh. A.2 § 602), 1998)

Article I. Improvements

17.30.030 Phasing of improvements.

The applicant may build the development in phases. If the development is to be phased the applicant shall submit a phasing plan to the public works superintendent for approval with the development application. The timing and extent or scope of public improvements and the conditions of development shall be determined by the city council on subdivision applications and by the public works superintendent on other development applications. (Ord. 974 § 4 (Exh. A.2 § 610), 1998)

17.30.040 Public improvements.

Except as specially provided, all public improvements shall be installed at the expense of the applicant and shall be constructed in accordance with the city’s public works design standards. All public improvements installed by the applicant shall be constructed and guaranteed as to workmanship and material as required by the public works design standards prior to acceptance by the city. A one-year warranty bond for all work and materials is required for 100 percent of the cost. The term of the warranty shall begin upon acceptance of the improvements by the city. No work shall be undertaken on any public improvement until after the construction plans have been approved by the public works superintendent and appropriate regulatory agencies and a public works permit issued and the required fees paid. (Ord. 974 § 4 (Exh. A.2 § 612), 1998)

17.30.050 Private improvements.

All private improvements shall be installed at the expense of the applicant. The property owner shall retain maintenance responsibilities over all private improvements. (Ord. 974 § 4 (Exh. A.2 § 614), 1998)

17.30.060 Construction timing.

A. All the public improvements required under this chapter shall be completed and accepted by the city prior to the issuance of a certificate of occupancy; or, for subdivision and partition applications, in accordance with the requirements of the subdivision regulations.

B. All private improvements required under this chapter shall be approved by the city prior to the issuance of a certificate of occupancy; or, for subdivision and partition applications, in accordance with the requirements of the subdivision regulations. (Ord. 974 § 4 (Exh. A.2 § 616), 1998)

Article II. Right-of-Way

17.30.070 Minimum street right-of-way widths.

A. The width of streets in feet shall not be less than the width required to accommodate a street improvement needed to mitigate the impact of a proposed development, as determined by the public works superintendent. In cases where a street is required to be improved, the width of the right-of-way shall not be less than the minimums indicated in the city’s public works design standards.

B. For subdivision and partition applications, wherever existing or future streets adjacent to property proposed for development are of inadequate right-of-way width the additional right-of-way necessary to comply with the public works design standards shall be shown on the final subdivision or partition plat prior to approval of the plat by the city. This right-of-way dedication shall be for the full width of the property abutting the roadway and, if required by the public works superintendent, additional dedications shall be provided for slope and utility easements if deemed necessary.

C. For development applications other than subdivisions and partitions, wherever existing or future streets adjacent to property proposed for development are of inadequate right-of-way width, the additional right-of-way necessary to comply with the city’s requirements as determined by the public works superintendent shall be dedicated to the city for use by the public prior to issuance of any building permit for the proposed development. This right-of-way dedication shall be for the full width of the property abutting the roadway and, if required by the public works superintendent, additional dedications shall be provided for slope and utility easements if deemed necessary.

D. For development applications that will impact existing streets not adjacent to the applicant’s property, and to construct necessary street improvements to mitigate those impacts would require additional right-of-way, the applicant shall be responsible for obtaining the necessary right-of-way from the property owner. A right-of-way dedication deed form shall be obtained from the public works superintendent and upon completion returned to the public works superintendent for acceptance by the city. On subdivision and partition plats the right-of-way dedication shall be accepted by the city prior to acceptance of the final plat by the city. On other development applications the right-of-way dedication shall be accepted by the city prior to issuance of building permits. The city may elect to exercise eminent domain and condemn necessary off-site right-of-way at the applicant’s request and expense. The city council shall determine when condemnation proceedings are to be used.

E. If the public works superintendent deems that it is impractical to acquire the additional right-of-way, as required in subsections B through D of this section, from both sides of the centerline in equal amounts, the public works superintendent may require that the right-of-way be dedicated in a manner that would result in unequal dedication from each side of the road. This requirement will also apply to slope and utility easements as discussed in RMC 17.30.090 and 17.30.100. The public works superintendent’s recommendation shall be presented to the planning commission in the preliminary plat approval for subdivisions and partitions, and in the recommended decision on all other development applications, prior to finalization of the right-of-way dedication requirements.

F. Whenever a proposed development is bisected by an existing or future road or street that is of inadequate right-of-way width according to the public works design standards, additional right-of-way shall be dedicated from both sides or from one side only as determined by the public works superintendent to bring the road right-of-way into compliance with this section.

G. When a proposed development is adjacent to or bisected by a street required by the public works superintendent and no street right-of-way exists at the time the development is proposed, the entire right-of-way as required in the public works design standards shall be dedicated by the applicant. The dedication of right-of-way required in this subsection shall be along the route of the road as determined by the city. (Ord. 974 § 4 (Exh. A.2 § 620), 1998)

17.30.080 Parcels excluded from development.

On subdivision development applications which include land partitioned off or having adjusted property lines from the original parcel, but do not include the original parcel, the applicant shall be responsible for obtaining any necessary right-of-way from the owner of the original parcel if the right-of-way is needed to accommodate street improvements required of the applicant. The applicant shall submit a completed right-of-way dedication deed to the public works superintendent for acceptance. The right-of-way dedication shall be accepted by the city prior to the city approving the final subdivision plat. (Ord. 974 § 4 (Exh. A.2 § 625), 1998)

Article III. Easements and Tracts

17.30.090 Slope easements.

A. The applicant shall obtain and convey to the city any slope easements determined by the public works superintendent to be necessary adjacent to the proposed development site to support the street improvements in the public right-of-way or accessway or utility improvements required to be constructed by the applicant;

B. For subdivision and partition applications, the slope easement dedication area shall be shown to be dedicated to the city on the final subdivision or partition plat prior to approval of the plat by the city; or

C. For all other development applications, a slope easement dedication shall be submitted to the public works superintendent; building permits shall not be issued for the development prior to acceptance of the easement by the city. (Ord. 974 § 4 (Exh. A.2 § 630), 1998)

17.30.100 Utility easements.

A. Utility easements for water, sanitary sewer and storm drainage facilities, telephone, television cable, gas, electric lines and other public utilities shall be granted to the city.

B. For subdivision and partition applications, the on-site public utility easement dedication area shall be shown to be dedicated to the city on the final subdivision or partition plat prior to approval of the plat by the city.

C. For subdivision and partition applications which require off-site public utility easements to serve the proposed development, a utility easement shall be granted to the city prior to approval of the final plat by the city. The city may elect to exercise eminent domain and condemn necessary off-site public utility easements at the applicant’s request and expense. The city council shall determine when condemnation proceedings are to be used.

D. For development applications other than subdivisions and partitions, and for both on-site and off-site easement areas, a utility easement shall be granted to the city; building permits shall not be issued for the development prior to acceptance of the easement by the city. The city may elect to exercise eminent domain and condemn necessary off-site public utility easements at the applicant’s request and expense. The city council shall determine when condemnation proceedings are to be used.

E. The width of the public utility easement shall meet the requirements of the public works design standards. All subdivisions and partitions shall have a six-foot public utility easement adjacent to the street and a five-foot public utility easement adjacent to all side and rear lot lines. (Ord. 974 § 4 (Exh. A.2 § 632), 1998)

17.30.110 Watercourse easements.

A. Where a proposed development site is traversed by or adjacent to a watercourse, drainage way, channel or stream, the applicant shall provide a storm water easement, drainage right-of-way, or other means of preservation approved by the public works superintendent, conforming substantially with the lines of the watercourse. The public works superintendent shall determine the width of the easement, or other means of preservation, required to accommodate all existing and future storm drainage needs and access for operation and maintenance.

B. For subdivision and partition applications, any watercourse easement dedication area shall be shown to be dedicated to the city on the final subdivision or partition plat prior to approval of the plat by the city.

C. For all other development applications, any watercourse easement shall be executed on a dedication form submitted to the public works superintendent; building permits shall not be issued for the development prior to acceptance of the easement by the city.

D. The storm water easement shall be sized to accommodate the existing watercourse and all future improvements in the drainage basin. Water quality facilities may require additional easements. (Ord. 974 § 4 (Exh. A.2 § 634), 1998)

17.30.120 Tracts.

A dedicated tract or easement will be required when access to public improvements for operation and maintenance is required, as determined by the public works superintendent. Access for maintenance vehicles shall be constructed of an all-weather driving surface capable of carrying a 50,000-pound vehicle. The width of the tract or easement shall be 15 feet in order to accommodate city maintenance vehicles. In subdivisions and partitions, the tract shall be dedicated to the city on the final plat. In any other development, an access easement shall be granted to the city and recorded prior to issuance of a building permit. (Ord. 974 § 4 (Exh. A.2 § 636), 1998)

The arrangement of streets in a subdivision shall either:

1. Provide for the continuation or appropriate projection of existing streets into surrounding areas; and/or

2. Conform to a street plan approved or adopted by the city to meet a particular situation where topographical or other conditions make continuance of or conformance to existing streets impractical.

C. The public works superintendent may require the applicant to submit a street plan showing all existing, proposed, and future streets in the area of the proposed development.

D. The public works superintendent may require the applicant to participate in the funding of future off-site street extensions when the traffic impacts of the applicant’s development warrant such a condition. (Ord. 974 § 4 (Exh. A.2 § 640), 1998)

17.30.140 Street improvements.

Whenever an applicant proposes to develop land adjacent to an existing or proposed street, including land which has been excluded under RMC 17.30.080, the applicant should be responsible for the improvements to the adjacent existing or proposed street that will bring the improvement of the street into conformance with the city’s comprehensive plan and the city’s public works design standards subject to the following provisions:

A. Design of the improvements on proposed or existing streets shall include the centerline profile 200 feet to either side of the development.

B. For any development proposed within the city, roadway facilities within the right-of-way described in RMC 17.30.070 shall be improved to standards as set out in the public works design standards.

C. The required improvements may include the rebuilding or the reconstruction of any existing facilities located within the right-of-way adjacent to the proposed development to bring the facilities into compliance with the public works design standards.

D. The required improvements may include the construction or rebuilding of off-site improvements which are identified to mitigate the impact of the development.

E. Where development abuts an existing street, the improvement required shall apply only to that portion of the street right-of-way located between the property line of the parcel proposed for development and the centerline of the right-of-way, plus any additional pavement beyond the centerline deemed necessary by the public works superintendent to ensure a smooth transition between a new improvement and the existing roadway (half-street improvement). Additional right-of-way and street improvements and off-site right-of-way and street improvements may be required by the city to mitigate the impact of the development. The new pavement shall connect to the existing pavement at the ends of the section being improved by tapering in accordance with the public works design standards.

F. All required street improvements shall include curbs, sidewalks, storm drainage, street lights, street signs, street trees, and, where designated, bikeways and transit facilities.

G. For subdivision and partition applications, the street improvements required by this chapter shall be completed and accepted by the city prior to signing the final subdivision or partition plat, or prior to releasing the security provided by the applicant to assure completion of such improvements or as otherwise specified in the development application approval.

H. For development applications other than subdivisions and partitions, all street improvements required by this section shall be completed and accepted by the city prior to the issuance of a certificate of occupancy.

I. In addition to land adjacent to an existing or proposed street, the requirements of this section shall apply to land separated from such a street only by a railroad right-of-way.

J. Streets within, or partially within, a proposed development site shall be graded for the entire right-of-way width and constructed and surfaced in accordance with the public works design standards.

L. Concrete sidewalks shall be constructed along both sides of each internal street and at a minimum along the development side of each external street in accordance with the public works design standards.

M. The applicant shall comply with the requirements of the Oregon Department of Transportation (ODOT) and Columbia County when a proposed development site is adjacent to a roadway under any of the jurisdictions, in addition to the requireements of this chapter.

N. The applicant shall construct any required street improvements adjacent to parcels excluded from development, as set forth in RMC 17.30.080.

O. The public works superintendent may determine that, although concurrent construction and placement of the improvements in subsection N of this section, either individually or collectively, are impractical at the time of development, the improvements will be necessary at some future date. In such a case, the applicant shall sign a written agreement guaranteeing future performance by the applicant and any successors in interest of the property being developed. The agreement shall be subject to the city’s approval. (Ord. 974 § 4 (Exh. A.2 § 642), 1998)

17.30.150 Streets, modifications of requirements in cases of unusual conditions.

A. When, in the opinion of the public works superintendent, the construction of street improvements in accordance with RMC 17.30.140 would result in the creation of a hazard, or would be impractical, or would be detrimental to the city, the public works superintendent may modify the scope of the required improvement to eliminate such hazardous, impractical, or detrimental results. Examples of conditions requiring modifications to improvement requirements include, but are not limited to, horizontal alignment, vertical alignment, significant stands of trees, the amount of traffic generated by the proposed development, timing of the development or other conditions creating hazards for pedestrian, bicycle or motor vehicle traffic. The public works superintendent may determine that, although an improvement may be impractical at the time of development, it will be necessary at some future date. In such cases, a written agreement guaranteeing future construction of the required improvements must be signed by the applicant, approved by the city and recorded on the deed and plat, or the applicant must provide the city cash in lieu of the construction. The cash shall be held in an account specifically for the improvement to the street and can only be used for that purpose. The cash amount shall be determined by the city.

B. When the public works superintendent determines that modification of the street improvement requirements in RMC 17.30.140 is warranted pursuant to subsection A of this section, the public works superintendent shall prepare written findings of modification. The public works superintendent shall forward a copy of said findings and description of modification to the applicant, or his authorized agent, as part of the development review for the proposed development. The decision of the public works superintendent may be appealed to the appropriate review authority. (Ord. 974 § 4 (Exh. A.2 § 644), 1998)
