7.92.010 Purpose. The purpose of this chapter is to inform applicants of general design standards for street and utility improvements and maintain consistency between this Ordinance and the Columbia City transportation system plan and public works design standards and specifications.

7.92.020 General provisions.

A. The standard specifications for construction, reconstruction or repair of streets, sidewalks, curbs and other public improvements within the city shall occur in accordance with the standards of this Ordinance, the public works design standards, the transportation system plan and county or state standards where appropriate.

B. The City Engineer may require changes or supplements to the standard specifications consistent with the application of engineering principles.

C. All applications for development shall conform to the standards established by this chapter.

          A.  No development shall occur unless the development has frontage on or approved access to a public local, collector or arterial street.  Private streets are not permitted in Columbia City.

         1.   Whenever existing streets adjacent to or within a tract are of inadequate width, additional right-of-way shall be provided at the time of land division.  Any new street or additional street width shall be dedicated and improved in accordance with this Ordinance, the Columbia City Transportation System Plan, and the Public Works Design Standards and Specifications.

        2.  The approval authority may accept and record a non-remonstrance agreement in lieu of street improvements if two or more of the following conditions exist:

        a.    A partial improvement creates a potential safety hazard to motorists or pedestrians;

        b.    Due to the nature of existing development on adjacent properties, it is unlikely that street improvements would be extended in the foreseeable future and the improvement associated with the project under review does not, by itself, provide a significant improvement to street safety or capacity;

          c.   The improvement is associated with an approved land partition on property zoned residential, and the proposed land partition does not create any new streets; or   

         d.   Additional planning work is required to define the appropriate design standards for the street, and the application is for a project which would contribute only a minor portion of the anticipated future traffic on the street.

         3.   Where steep terrain or existing development constrain vehicular access from the approved street frontage to a lot of record existing on September 1, 2003, the approval authority may approve use of an alley for vehicular access to a garage or carport, subject to the following: 

         a.   Where the existing alley right-of-way does not extend through the block, the alley shall be improved to a paved width of not less than 16 feet to the point of vehicular access to the garage or carport.

         b.   Where the existing alley right-of-way extends through the block, the alley shall be improved to a paved width of not less than 16 feet for two-way access or not less than 12 feet for one-way access.  Where one-way alley access is approved, the alley shall be posted accordingly. 

         c.    When use of an alley is approved for vehicular access to a garage or carport, no on-street parking shall be permitted in the alley and the alley shall be posted accordingly.  

         d.   When use of an alley is approved for vehicular access to a garage or carport, the property line adjacent to the public local, collector or arterial street on which the residence is addressed shall be regarded as the front lot line.   The front façade of the residence shall be oriented to the public local, collector or arterial street on which the residence is addressed.

        4.  In new subdivisions, the Planning Commission may approve creation of alleys to provide vehicular access to garages subject to the following:

         a.  The alley right-of-way shall be twenty (20) feet in width and shall extend through the block;

        b.  The alley shall be improved to a paved width of twenty (20) feet;

         c.   No on-street parking shall be permitted in the alley and the alley shall be posted accordingly.  

        d.  The property line adjacent to the local, collector or arterial street on which the residence is addressed shall be regarded as the front lot line.   The front façade of the residence shall be oriented to the public local, collector or arterial street on which the residence is addressed.

[Amended by Ordinance No. 03-589-O 9/18/03]

B. Rights-of-way shall normally be created through the approval of a final partition or subdivision plat.

1. The Council may approve the creation of a street by deed of dedication if any establishment of a street is initiated by the council and is found to be essential for the purpose of general traffic circulation, and partitioning of subdivision of land has an incidental effect rather than being the primary objective in establishing the road or street for public use.

2. All deeds of dedication shall be in a form prescribed by the City and shall name "the Columbia City, Oregon" as the grantee.

3. All instruments dedicating land to public use shall bear the approval by the Mayor accepting the dedication prior to recording.

4. No person shall create a street or road for the purpose of partitioning an area or tract of land without the approval of the city.

C. When location is not shown in the Columbia City Transportation System Plan, the arrangement of the streets shall:

1. Provide for the continuation or appropriate projection of existing streets in the surrounding areas, or conform to a plan for the neighborhood approved by the Commission to meet a particular situation where topographical or other conditions make continuance or conformance to existing street impractical. Such a plan shall be based on the type of land use to be served, the volume of traffic, the capacity of adjoining streets and the need for public convenience and safety.

2. New streets shall be laid out to provide reasonably direct and convenient routes for walking and cycling within neighborhoods and accessing adjacent development.

D. Street right of way and roadway widths shall be as shown in the Columbia City Transportation System Plan. Where conditions, particularly topography or the size and shape of the tract, make it impractical to otherwise provide buildable sites, narrower right of way may be accepted. If necessary, slope easements may be required.

E. Reserve strips or street plugs controlling access to streets will not be approved unless necessary for the protection of the public welfare or of substantial property rights, and in those cases, they shall be required and shall be dedicated to the City on the final plat.

F. Except for extensions of existing streets, no street name shall be used which will duplicated or be confused with the name of an existing street. Street names and numbers shall conform to the established pattern in the City and shall be subject to the approval of the Commission.

G. Streets shall be laid out to intersect at angles as near to right angles as practical except where topography requires a lesser angle, but in no case shall the acute angle be less than eighty (80) degrees, unless there is a special intersection design. An arterial or collector street intersecting with another street shall have at least one hundred (100) feet of tangent adjacent to the intersection, unless topography requires a lesser distance. Other streets, except alleys, shall have at least five hundred (500) feet of tangent to the intersection unless topography requires a lesser distance. Intersections which contain an acute angle of less than eighty (80) degrees, or which include an arterial street, shall have a minimum corner radius sufficient to allow for a roadway radius of twenty (20) feet and maintain a uniform width between the roadway and right of way line. Ordinarily, the intersection of more than two streets at any point will not be approved.

H. Half streets, while generally not acceptable, may be approved where essential to the reasonable development of the site when in conformity with the other requirements of these regulations, and when the approval authority finds it will be practical to require the dedication of the other half when adjoining property is divided or developed. Half streets shall require a minimum paving width of 20 feet in addition to curbs, gutters, sidewalks, and storm drainage. Whenever an existing half street is adjacent to a tract to be divided or developed, the other half of the street shall be provided within such tract. Reserve strips and street plugs pursuant to Section 7.92.030 (E) may be required to preserve the objectives of half streets.

I. A cul-de-sac shall be as short as possible, shall have a maximum length of four hundred (400) feet and shall serve building sites for not more than eighteen (18) dwelling units. A cul-de-sac shall terminate with a circular turnaround.

J. Grades shall not exceed six percent (6%) on arterials, ten percent (10%) on collector streets, or twelve percent (12%) on other streets.  Center line radii of curves shall not be less than three hundred (300) feet on major arterials, two hundred (200) feet on secondary arterials, or one hundred (100) feet on other streets and shall be to an even ten (10) feet.   Where existing conditions, particularly the topography, make it otherwise impractical to provide building sites, the City Engineer may approve steeper grades and sharper curves, subject to the approval of the Fire Marshal.  In flat areas, allowance shall be made for finished street grades having a minimum slope of at least one-half of one percent (0.5%).  [Amended by Ordinance No. 03-589-O 9/18/03]

K. Wherever the proposed land division or development contains or is adjacent to a railroad right-of-way, provision may be required for a street approximately parallel to and on each side of such right-of-way at a distance suitable for the appropriate use of the land between the streets and the railroad. The distance shall be determined with due consideration at cross streets of the minimum distance required for approach grades to a future grade separation and to provide sufficient depth to allow screen planting along the railroad right-of-way.

L. Where an adjacent development results in a need to install or improve a railroad crossing, the cost for such improvements may be a condition of development approval, or another equitable means of cost distribution shall be determined by the City Engineer and approved by the City Council.

M. Where a land division or development abuts or contains an existing or proposed arterial street, the Commission may require marginal access streets, reverse frontage lots with suitable depth, screen planting contained in a non access reservation along the rear or side property line, or other treatment necessary for adequate protection of residential development design shall provide adequate protection for residential properties, and to afford separation of through and local traffic.

N. Concrete vertical curbs, curb cuts, wheelchair, bicycle ramps and driveway approaches shall be constructed in accordance with public works design standards where required by the Columbia City Transportation System Plan. Driveways shall be asphalt or concrete, not less than four inches deep or two inches of asphalt on four inches of three-fourths-inch minus gravel.

Classification Posted Speed Minimum spacing between driveways

And/or Streets  

Highway 30 N/A As permitted by ODOT

Collector Street 25 mph 75 feet

Local Street 25 mph 50 feet

Where spacing standards cannot be satisfied for existing lots of record adjacent to collector or local streets, shared driveways serving no more than two residences may be permitted with a recorded reciprocal access and maintenance agreement.

P. Upon completion of a street improvement and prior to acceptance by the City, it shall be the responsibility of the developer's registered professional land surveyor to provide certification to the city that all boundary and interior monuments shall be established or re-established, protected and recorded.

Q. The developer shall install all street signs, relative to traffic control and street names, as specified by the public works director for any development. The cost of signs shall be the responsibility of the developer.

R. The location of traffic signals shall be noted on approved street plans, and where a proposed street intersection will result in an immediate need for a traffic signal, a city-approved signal shall be installed. The cost shall be included as a condition of development.

S. Street lights shall be installed in accordance with the city's public works design standards and shall be served from an underground source of supply.

7.92.040 Blocks and Lots.

A. The length, width, and shape of blocks shall take into account the need for adequate building site size and street width, and shall recognize the limitations of the topography.

B. No block shall be more than one thousand (1000) feet in length between street corner lines unless it is adjacent to an arterial street, or unless the topography or the location of adjoining streets justifies an exception. The recommended minimum length of blocks along an arterial street is one thousand eight hundred feet. A block shall have sufficient width to provide for two tiers of building sites unless topography or the location of adjoining streets justifies the exception.

C. Through lots and parcels shall not be permitted except where they are essential to provide separation of residential development from major traffic arteries or adjacent non-residential activities, or to overcome specific disadvantages or topography and orientation. A planting screen easement at least ten (10) feet wide, and across which there shall be no right of access, shall be required along the line of building sites abutting such a traffic artery or other incompatible use. The planting screen easement shall be landscaped in accordance with the requirements for screening in Chapter 7.96.

D. The lines of lots and parcels, as far as is practicable, shall run at right angles to the street upon which they face, except that on curved streets they shall be radial to the curve.

E. The Planning Commission may approve the creation of a flag lot for residential development when necessary to achieve planning objectives, such as reducing direct access to roadways, providing existing internal platted lots with access to a residential street, meeting the desired density standards for the zone, or preserving natural or historic resources, when all of the following criteria are satisfied:

1. The depth of the existing legal lot of record is equal to or more than two times the lot depth required by the zone; and

2. The result would not increase the number of properties requiring direct and individual access connections to the State Highway System or other arterials; and

3. No more than one lot shall be permitted per deeded access flag; and

4. All affected driveways shall meet the access spacing standard except where flag lots on adjacent properties share a common property line and the driveway for each flag lot is constructed immediately adjacent to the common property line and functions as a shared driveway with a recorded reciprocal access and maintenance agreement; and

5. The flag access shall have a minimum width of 20 feet and a maximum width of 25 feet; and

6. The flag driveway shall have a minimum paved width of 12 feet; and

7. In no instance shall flag lots constitute more than two lots in a partition or a subdivision; and

8. The lot area for a flag lot shall comply with the lot area requirements of the applicable zoning district and shall be provided entirely within the building site area exclusive of any accessway.

A. Easements for sewers, drainage, water mains, electric lines or other public utilities shall be granted wherever necessary. The easements shall be at least sixteen (16) feet wide and centered on lot or parcel lines, except for utility pole tie-back easements which may be reduced to six (6) feet in width. The property owner proposing a development shall make arrangements with the city, the applicable district and each utility franchise for the provision and dedication of utility easements necessary to provide full services to the development.

B. If a tract is traversed by a watercourse, such as a drainageway, channel or stream, there shall be provided a stormwater easement or drainage right-of-way conforming substantially with the lines of such watercourse and such further width as will be adequate for the purpose. Streets or parkways parallel to the major water courses may be required.

C. When desirable for public convenience, a pedestrian or bicycle way may be required to connect a cul-de-sac or to pass through an unusually long or oddly shaped block or otherwise provided appropriate circulation.

7.92.060 Sidewalks.

A. On public streets, sidewalks are required except as exempted by the Columbia City Transportation System Plan and shall be constructed, replaced or repaired in accordance with the city's public works design standards.

B. Maintenance of sidewalks and curbs is the continuing obligation of the adjacent property owner.

C. The City may accept and record a non-remonstrance agreement for the required sidewalks from the applicant for a building permit for a single-family residence when the City Engineer determines the construction of the sidewalk is impractical for one or more of the following reasons:

1. The residence is an in-fill property in an existing neighborhood and the adjacent residences do not have sidewalks;

2. Topography or elevation of the sidewalk base area makes construction of a sidewalk impractical.

A. If the City has an interest in acquiring a portion of a proposed subdivision or development for a public purpose, or if the City has been advised of such interest by a school district or other public agency, and there is reasonable assurance that steps will be taken to acquire the land, the Commission may require, as a condition of approval, that that portion of the subdivision or development be reserved for public acquisition for a period not to exceed two (2) years at a cost not to exceed the value of the land prior to the subdivision or development. Such land shall be released to the property owner if not purchased by a public agency within 2 years of the date of the final decision.

B. Within or adjacent to a subdivision, a parcel of land may be set aside and dedicated to the public by the subdivider. The size of this parcel shall be determined by the distance from the existing City parks and the number of people to be housed by said subdivision. The parcel shall be approved by the Commission as being suitable and adaptable for park and recreation areas. The developer may be eligible for credit on parks systems development charges for such a dedication.

7.92.080 Sanitary sewers.

A. Sanitary sewers shall be installed to serve each new development and to connect developments to existing mains in accordance with the provisions set forth by the city's public works design standards and the adopted policies of the comprehensive plan.

B. The City Engineer shall approve all sanitary sewer plans and proposed systems prior to issuance of development permits involving sewer service.

C. Proposed sewer systems shall include consideration of additional development within the area as projected by the comprehensive plan and the wastewater treatment facility plan and potential flow upstream in the sewer sub-basin.

D. Applications shall be denied by the approval authority where a deficiency exists in the existing sewer system or portion thereof which cannot be rectified within the development and which if not rectified will result in a threat to public health or safety, surcharging of existing mains, or violations of state or federal standards pertaining to operation of the sewage treatment system.

A. Permits shall be issued only where adequate provisions for stormwater and floodwater runoff have been made, and:

1. The stormwater drainage system shall be separate and independent of any sanitary sewerage system.

2. Where possible, inlets shall be provided so surface water is not carried across any intersection or allowed to flood any street.

3. Surface water drainage patterns shall be shown on every development proposal plan.

4. All stormwater analysis and calculations shall be submitted with proposed plans for review and approval.

5. All stormwater construction materials shall be subject to approval of the City Engineer.

B. A culvert or other drainage facility shall, and in each case be, large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the development. The City Engineer shall determine the necessary size of the facility.

C. Where it is anticipated by the City Engineer that the additional runoff resulting from the development will overload an existing drainage facility, the City shall not approve the infrastructure construction permits or any other construction permits until provisions have been made for improvement of the potential condition or until provisions have been made for storage of additional runoff caused by the development.

D. Drainage facilities shall be provided within a subdivision or development and to connect the subdivision or development drainage to drainage ways or storm sewers off site. Design of drainage, as provided by the City Engineer, shall take into account the capacity and grade necessary to maintain unrestricted flow from areas draining through the subdivision or development and to allow extension of the system to serve such areas.

E. Street improvements shall include installation of catch basins with oil/water separators connected to drainage tile leading to storm sewers or drainage ways.

7.92.100 Water System.  The Planning Director and City Engineer shall issue permits only where provisions for municipal water system extensions have been made, and: 

A. Any water system extension shall be designed in compliance with the Comprehensive Plan and existing water system plans.  Waterlines shall be improved to a minimum size of 6 inches in diameter for in fill development.  [As amended by Ordinance No. 06-619-O 7/2/06]           

B. Extensions shall be made in such a manner as to provide for adequate flow and looping of the system. 

C. The City Engineer shall approve all water system construction materials.  

D. Water lines and fire hydrants serving each building site in the subdivision or development and connecting the subdivision or development to City mains shall be installed. 

E.  Applications shall be denied by the approval authority where a deficiency exists in the existing water system or portion thereof which cannot be rectified within the development and, which if not rectified, will result in a threat to public health or safety. 

7.92.110 Bikeways. 

A.  Developments adjoining proposed bikeways as shown in the Columbia City Transportation System Plan shall include provisions for the future extension of such bikeways through the dedication of easements or rights-of-way. 

B. Minimum width for bikeways is four paved feet per travel lane. 

7.92.120 Utilities. 

A.  All utility lines including, but not limited to those required for electric, communication, lighting and cable television services and related facilities shall be placed underground, except for surface mounted transformers, surface mounted connection boxes and meter cabinets which may be placed above ground, temporary utility service facilities during construction, high capacity electric lines operating at fifty thousand volts or above, and:
