16.20.010 Compliance with zone area and dimension requirements.
All new lots shall conform to the provisions of Title 17 RRMC and this title for lot area, lot width, setbacks, site development standards and the following criteria. [Ord. 11-373-O § 8-7:4.105].
16.20.020 Buildable lots.
Each new lot shall be designed as a buildable lot, taking into consideration topography, soils, floodplain and other site limitations. [Ord. 11-373-O § 8-7:4.110].
16.20.030 Lot width to depth ratio.
Lot depth shall not exceed three times lot width. This standard may be exceeded:
A. Where a portion of a lot is located within the floodway and the portion outside of the floodway cannot be further divided; or
B. Where a flag lot is approved under RRMC 16.20.070. [Ord. 11-373-O § 8-7:4.120].
16.20.040 Through lots.
Lots that have frontage on more than one street, except corner lots, shall be avoided except where necessary to provide separation of residential developments from arterial streets or to overcome specific topographic constraints.
A. Lots that front on more than one street shall be required to locate motor vehicle accesses on the street with the lower functional classification.
B. When a residential subdivision is proposed that would abut an arterial, it shall be designed to provide through lots along the arterial with access from a frontage road or interior local road. A berm or buffer yard may be required at the rear of through lots to buffer residences from traffic on the arterial. The berm or buffer yard shall not be located within the public right-of-way. [Ord. 11-373-O § 8-7:4.130].
16.20.050 Side property line.
As far as practical, the side property line of the lot shall run at right angles to the street upon which it faces, except that on a curved street the side property line shall be radial to the curve. [Ord. 11-373-O § 8-7:4.140].
16.20.060 Curved property line at street intersections.
At all street intersections, an arc along the property line shall be established to allow construction of standard curb and sidewalk wholly within the right-of-way. [Ord. 11-373-O § 8-7:4.150].
16.20.070 Flag lots.
All flag lots shall meet the following requirements:
A. A street cannot reasonably or practically be created to serve the property.
B. The flag pole shall be at least 25 feet in width. The maximum length for a flag pole shall be twice the width of the lot or twice the length of the lot, whichever dimension is less.
C. The flag pole shall be designed such that a driveway meeting city standards could be constructed within the flag pole, unless an alternative access is provided by easement. The access shall not encroach upon or cross a live stream, ravine, irrigation ditch or similar topographic feature without provision for an adequate structure, fill, or culvert to provide access for emergency vehicles. Any such required structure shall be constructed prior to final plat approval for the partition, subdivision or planned unit development which approved the flag lot. The structure shall be certified by a registered engineer as meeting this standard.
D. Abutting flag poles are not permitted, unless approved through the variance procedures in Chapter 16.50 RRMC.
E. Flag lots shall not be permitted when the result would be to increase the number of properties requiring direct and individual access connections to the state highway system or other arterials, unless approval for the additional access is given by the highway or arterial street authority.
F. Flag lots may be permitted for residential development when necessary to achieve planning objectives, such as reducing direct access to roadways, providing internal platted lots with access to a residential street, or preserving natural or historic resources, under the following conditions:
1. Flag lot driveways shall be separated by at least twice the minimum frontage requirement of the underlying zoning district.
2. The flag driveway shall have a minimum width of 12 feet and maximum width of 24 feet.
3. In no instance shall flag lots constitute more than 10 percent of the total number of building sites in a recorded or unrecorded plat, or more than three lots, whichever is greater.
4. The lot area occupied by the flag driveway shall not be counted as part of the required minimum lot area of that property.
5. No more than one flag lot shall be permitted per private right-of-way or access easement. [Ord. 23-418-O § 96; Ord. 11-373-O § 8-7:4.200].

1. East Main Street, West Main Street, Depot Street, Pine Street.
2. East Evans Creek, West Evans Creek, Foothill Boulevard, North River Road, Wards Creek Road, Rogue River Highway.
2. Cul-de-Sacs. Radius for turn-around at the end of cul-de-sacs shall have a minimum right-of-way width of 40 feet and a minimum roadway width of 28 feet.
3. Private driveways accessing city streets shall have a minimum width of 12 feet, and shall be paved with asphaltic concrete, concrete or a permeable rock material approved by the city. Where physical conditions, particularly topography or the size and shape of the tract, make it impractical to otherwise provide buildable sites or less than adequate rights-of-way, the matter shall be submitted for determination, using the variance procedure in Chapter 16.50 RRMC.
C. Reserve Strips. Reserve strips or street plugs controlling access to streets shall be approved where necessary for the protection of the public welfare or of substantial property rights. The control and disposal of the land comprising such strips shall be placed within the jurisdiction of the city under conditions approved by the city council.
D. Alignment. As far as is practical, streets shall be in alignment with existing streets by continuations of the centerlines thereof. Staggering of streets making “T” intersections at collectors and arterials shall not be designed so that jogs of less than 300 feet on such streets are created, as measured from the centerline of the street intersections.
E. In order to promote efficient vehicular and pedestrian circulation throughout the city, the design of subdivisions and alignment of new streets shall conform to the following standards. The maximum block length shall not exceed:
1. Six hundred feet in residential districts;
2. Four hundred feet in commercial districts; and
3. Not applicable to industrial districts.
Exceptions to the above standards may be granted when an accessway is provided at or near mid-block.
F. Spacing between local street intersections shall have a minimum separation of 125 feet, except where more closely spaced intersections are designed to provide an open space, pocket park, common area or similar neighborhood amenity. This standard applies to four-way and three-way (offset) intersections.
G. Minor collector and local residential streets shall connect with surrounding streets to permit the convenient movement of traffic between residential neighborhoods and facilitate emergency access and evacuation. Appropriate design and traffic control such as four-way stops and traffic calming measures are the preferred means of discouraging or minimizing through traffic.
H. Development Adjoining Arterial Streets. Where development adjoins or is crossed by an existing or proposed arterial street, the development design shall separate residential access from through traffic and shall minimize traffic conflicts. The design shall include one or more of the following transportation elements:
1. A parallel access street along the arterial with a landscape buffer separating the residential and through streets;
2. Deep through lots abutting an arterial or major collector to provide adequate buffering with frontage along a residential street. Through lots shall conform to the buffering standards in RRMC 16.20.040;
3. Screen planting at the rear or side property line should be contained in a non-access reservation or reserve strip along the arterial; or
4. Other treatment suitable to meet the objectives of this subsection;
5. If a lot has access to two streets with different classifications, primary access shall be from the lower classification street.
I. Proposed streets or street extensions shall be located to provide direct access to existing or planned commercial services and other neighborhood facilities, such as schools, shopping areas and parks.
J. Future Extensions of Streets. Where necessary to give access to or to divide adjoining land, streets shall be extended to the boundary of the subdivision or partition. The resulting dead-end streets may be approved with a temporary turn-around. Reserve strips and street plugs may be required to preserve the objective of street and utility extensions.
K. All local and collector streets which abut a development site shall be extended within the site to provide through circulation unless prevented by environmental or topographical constraints, existing development patterns or compliance with other standards in this code. This exception applies when it is not possible to redesign or reconfigure the street pattern to provide required extensions. Land is considered topographically constrained if the slope is greater than 15 percent for a distance of 250 feet or more. In the case of environmental or topographical constraints, the mere presence of a constraint is not sufficient to show that a street connection is not possible. The applicant must show why the environmental or topographic constraint precludes some reasonable street connection.
L. Intersection Angles. Streets shall be laid out so as to intersect at an angle as near to a right angle as practicable, except where topography requires a lesser angle or where a reduced angle is necessary to provide an open space, pocket park, common area or similar neighborhood amenity. In addition, the following standards shall apply:
1. Streets shall have at least 25 feet of tangent adjacent to the right-of-way intersection unless topography requires a lesser distance;
2. Intersections which are not at right angles shall have a minimum corner radius of 20 feet along the right-of-way lines of the acute angle; and
3. Right-of-way lines at intersection with arterial streets shall have a corner radius of not less than 20 feet.
M. Existing Streets. Whenever existing streets adjacent to or within a tract are of inadequate width, additional right-of-way shall be provided at the time of the land division. Unimproved streets shall be improved at the cost of the developer.
N. Half Street. Half streets, while generally not acceptable, may be approved where essential to the reasonable development of the land division, when in conformity with the other regulations and when the city council finds it will be practical. Whenever a half street is adjacent to a tract to be divided, the other half of the street shall be provided within such tract. Reserve strips and street plugs may be required to preserve the objectives of half streets.
O. Cul-de-Sac. A cul-de-sac shall be as short as possible and shall have a maximum length of 400 feet and serve not more than 18 dwelling units. A cul-de-sac shall terminate with a circular turn-around. Cul-de-sacs or permanent dead-end streets may be used as part of a development plan; however, through streets are encouraged except where topographical, environmental, or existing adjacent land use constraints make connecting streets infeasible. Where cul-de-sacs are planned, accessways shall be provided connecting the ends of cul-de-sacs to each other, to other streets, or to neighborhood activity centers.
P. Accessways.
1. Accessways for pedestrians and bicyclists shall be 10 feet wide and located within a right-of-way or easement. If the streets within the subdivision are lighted, the accessways shall also be lighted. Stairs or switchback paths may be used where grades are steep.
2. Accessways for pedestrians and bicyclists shall be provided at mid-block where the block is longer than 600 feet.
3. The city may determine, based upon evidence in the record, that an accessway is impracticable. Such evidence may include but is not limited to:
a. Physical or topographic conditions make an accessway connection impractical. Such conditions include but are not limited to freeways, railroads, extremely steep slopes, wetlands, or other bodies of water where a connection cannot reasonable be provided.
b. Buildings or other existing development on adjacent lands physically preclude a connection now or in the future, considering the potential for redevelopment.
c. Where accessways would violate provisions of easements, covenants, restrictions, or other agreements existing as of May 1, 1995, that preclude a required accessway connection.
Q. Sidewalks, Planter Strips, Bicycle Lanes. Sidewalks, planter strips, and bicycle lanes shall be installed in conformance with the Rogue River street standards. Maintenance of sidewalks, curbs, and planter strips is the continuing obligation of the adjacent property owner.
R. Street Names. Except for extensions of existing streets, no street name shall be used which will duplicate or could be confused with the name of an existing city street or county road. Street names and numbers shall conform to the established pattern in the city and shall be subject to the approval of the city council.
S. Grades and Curves. Grades shall not exceed six percent on arterials, 10 percent on collector streets or 12 percent on other streets. Centerline radii of curves shall not be less than 300 feet on major arterials, 200 feet on collectors or 100 feet on other streets, and shall be to an even 10 feet. Where existing conditions, particularly the topography, make it otherwise impractical to provide buildable sites, the planning commission may accept steeper grades and sharper curves. In flat areas, allowance shall be made for finished street grades having a minimum slope, preferably of at least one-half percent.
T. Streets Adjacent to Railroad Right-of-Way. Wherever the proposed land division 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.
U. Alleys. Alleys shall be provided in commercial and industrial districts, unless other permanent provisions for access to off-street parking and loading facilities are approved by the city council. The corners of alley intersections shall have a radius of not less than 12 feet.
V. Street lights shall be installed in accordance with city standards. [Ord. 23-418-O § 97; Ord. 11-373-O § 8-7:4.420].
