Libraries, museums, community centers, and similar uses. These uses are allowed conditionally if a finding can be made that it is not feasible to locate in the civic overlay district.
Telecommunication equipment, including wireless.
D. Prohibited Auto Oriented And Auto Dependent Uses: Auto oriented uses including drive-through facilities are not permitted in the DB district (e.g., gas stations, vehicle repair/sales/service, drive-through uses). Auto dependent uses such as gas stations, car washes, and similar uses are also prohibited. Drive-through facilities for banks are not subject to this prohibition; they are permitted. Drive-through facilities for banks shall be located to the side or rear of the building and accessed from side streets.
E. Minimum Lot Dimensions: No minimum lot dimensions are required. Lot dimensions may be established during site plan review.
F. Minimum Yard Requirements: The following yard requirements are the base standards and may be modified during site plan review.
1. Front Yard Setback: There is no minimum front yard setback requirement.
2. Rear Yard Setback: The minimum rear yard setback for all structures shall be zero feet (0') for street access lots and six feet (6') for alley access lots.
3. Side Yard Setbacks: There is no minimum side yard setback required.
4. Setback Exceptions: Eaves, chimneys, bay windows, overhangs, cornices, awnings, canopies, porches, decks, pergolas, and similar architectural features may encroach into setbacks by no more than six feet (6'), subject to compliance with applicable standards of the uniform building code and uniform fire code.
G. Lot Coverage: No lot coverage dimensions are required except compliance with other sections of this title, including site plan review, may preclude one hundred percent (100%) coverage.
H. Height Requirements: Building shall be no more than forty five feet (45') in height.
I. Building Orientation Standards: The following standards are intended to orient buildings close to streets to promote human scale development, slow traffic down, and encourage walking in the DB district. Placing buildings close to the street also encourages security and safety by having more "eyes on the street".
All buildings in the DB district shall be oriented to the street. The building orientation standard is met when all of the following criteria are met:
1. Compliance with the setback standards in subsection F of this section.
2. All buildings shall have their primary entrance(s) oriented to the street.
3. A direct walkway not exceeding fifteen feet (15') shall be provided between the building entrance and street right of way.
4. Off street parking, drives, and other vehicle areas shall not be placed between buildings and streets.
J. Architectural Guidelines And Standards: These standards apply to townhomes, duplex and triplex developments, multi-family housing, public and institutional buildings, commercial, and mixed use buildings. They are intended to provide detailed, human scale design.
1. Detailed Storefront Design: All buildings shall contribute to the storefront character and visual relatedness of Main Street buildings.
a. Corner building entrances on corner lots are encouraged.
b. Regularly spaced and similar shaped windows are encouraged, consistent with the historic character.
c. Large display windows on ground floors shall be provided (nonresidential uses only).
d. Decorative cornices at the top of buildings (flat roof), or eaves with a pitched roof, are required.
2. Design Of Large Scale Buildings And Developments: The standards below shall apply to "large scale buildings and development" as defined in subsections J2a and J2b of this section:
a. Buildings with greater than twenty thousand (20,000) square feet of enclosed ground floor space. Multi-tenant buildings shall be counted as the sum of all tenant spaces within the same building shell; and
b. Multiple-building developments with a combined ground floor space (enclosed) greater than forty thousand (40,000) square feet.
c. All large scale buildings and development, as defined in subsections J2a and J2b of this section, shall provide human scale design by conforming to all of the following criteria:
(1) Incorporate changes in building direction (articulation), and divide large masses into varying heights and sizes. Such changes may include building offsets; projections; changes in elevation or horizontal direction; sheltering roofs; terraces; a distinct pattern of divisions in surface materials; and use of windows, screening trees; and small scale lighting.
(2) Every building elevation adjacent to a street with a horizontal dimension of fifty feet (50'), as measured from end wall to end wall, shall have a building entrance, except that building elevations that are unable to provide an entrance due to the internal function of the building space (i.e., mechanical equipment, area where the public or employees are not received, etc.) may not be required to meet this standard. Pathways shall connect all entrances to the street right of way.
K. Pedestrian And Transit Amenities: This section is intended to complement the building orientation standards and street standards by providing comfortable and inviting pedestrian spaces within the downtown. Pedestrian amenities serve as informal gathering places for socializing, resting, and enjoyment of the downtown, and contribute to a walkable district. This section applies to three (3) or more attached townhomes on their own lots, duplexes and triplexes, multi-family housing, public and institutional buildings, commercial, and mixed use buildings.
1. Guidelines: Each development shall provide one or more of the following:
a. A plaza, courtyard, street furniture, square or extra wide sidewalk next to the building entrance.
b. Sitting space (i.e., dining area, benches or ledges between the building entrance, and sidewalk [a minimum of 16 inches in height and 30 inches in width]).
c. Building canopy, awning, pergola, or similar weather protection (minimum projection of 4 feet over a sidewalk or other pedestrian space).
d. Public art which incorporates seating (e.g., fountain, sculpture, etc.).
L. Special Standards For Certain Uses: This section contains standards to control the scale and compatibility of those uses within the DB district. These are in addition to those listed in chapter 8 of this title. If any conflicts arise between this section and chapter 8 of this title, the more restrictive standard shall apply unless adjusted by the planning commission or city council.
a. Permitted When: Residential uses shall be permitted only when part of a mixed use development.
b. Limitation On Street Level Housing: No more than fifty percent (50%) of a single street frontage may be occupied by residential uses. This standard is intended to reserve storefront space for commercial uses and public uses; it does not limit residential uses above the street level on upper stories.
c. Density: There is no minimum or maximum density standard.
d. Parking, Garages, And Driveways: Parking shall be oriented to alleys, placed in aboveground floors, or located to the side or behind buildings.
e. Creation Of Alleys: When a subdivision is proposed, a public or private alley shall be created for the purpose of vehicle access. Alleys are not required when existing development patterns or topography make construction of an alley impracticable.
f. Common Areas: All common areas (e.g., walkways, drives, courtyards, private alleys, parking courts, etc.) and building exteriors shall be maintained by a homeowners' association or other legal entity. Copies of any applicable covenants, restrictions, and conditions shall be recorded and provided to the city prior to building permit approval.
M. Accessory Uses And Structures: Accessory uses and structures are of a nature customarily incidental and subordinate to the principal use or structure on the same lot. Typical accessory uses in a downtown include small workshops, greenhouses, studios, storage sheds, and similar structures. Accessory structures shall comply with the following:
1. Primary Use Required: An accessory structure shall not be allowed before or without a primary use.
2. Setback Standards: Accessory structures shall comply with required setback standards.
3. Design Guidelines: Accessory structures shall comply with the design guidelines as provided in this chapter.
4. Restrictions: A structure shall not be placed over an easement that prohibits such placement and shall not encroach into the public right of way.
N. Access And Circulation: The intent of this section is to manage vehicle access to the development through a connected street system, while preserving the flow of traffic in terms of safety, roadway capacity, and efficiency. This section shall apply to all properties that abut a public street.
1. Access Options: When vehicle access is required for development, access shall be provided by one of the following methods (a minimum 10 feet per lane is required). These methods are "options" to the developer, unless one method is specifically required under special standards for certain uses.
a. Option 1: Access from an existing or proposed alley or midblock lane.
b. Option 2: Access from a private street or driveway connecting to an adjoining property that has direct access to a public street ("shared driveway"). A shared public access easement covering the driveway shall be recorded in this case to assure access to the closest public street for all users of the street/driveway.
c. Option 3: Access from South Main if an access permit is approved by Oregon department of transportation.
d. Option 4: Access from a public right of way other than South or North Main Street.
2. Special Provisions: Direct street access may be restricted for some land uses. For example, access consolidation, shared access, and/or access separation greater than is required in the transportation system plan may be required by the city or Oregon department of transportation for the purpose of protecting the function, safety and operation of the street for all users.
3. Number Of Access Points: One street access per lot is allowed, except that two (2) access points may be allowed for corner lots.
4. Access Spacing: Access spacing requirements shall follow the recommendations outlined in the most current transportation system plan.
5. Driveway Openings: Driveway openings, or curb cuts, shall be the minimum width necessary to provide the required number of vehicle travel lanes (10 feet for each travel lane). The following standards are required to provide adequate site access, minimize surface water runoff, and avoid conflicts between vehicles and pedestrians:
a. Single-family and duplex uses shall have a minimum driveway width of ten feet (10') and a maximum width of twenty four feet (24').
b. Multiple-family uses with between four (4) and seven (7) dwelling uses shall have a minimum driveway width of twenty feet (20') and a maximum width of twenty four feet (24').
c. Multiple-family uses with eight (8) or more dwelling units and off street parking areas with sixteen (16) or more spaces shall have a minimum driveway width of twenty four feet (24') and a maximum width of thirty feet (30').
d. Access widths of all other uses shall be based on ten feet (10') of width for every travel lane.
e. Driveway aprons (when required) shall be constructed of concrete and installed between the right of way and the private drive. Driveway aprons shall conform to ADA standards for sidewalks and pathways, which require a continuous travel lane that is a minimum of three feet (3') in width, with a cross slope not exceeding two percent (2%).
6. Construction Driveways, Parking Areas, And Turnarounds: Construction driveways, parking areas, and turnarounds may be paved with asphalt, concrete, or comparable surface, or a durable nonpaving material may be used to reduce surface water runoff and protect water quality. When paved surfaces are used, all driveways, parking areas, and turnarounds shall have on site collection or infiltration of surface waters to eliminate sheet flow of such waters onto public rights of way and abutting property.
O. Site Planning And General Building Design Standards: So far as practicable, all original exterior materials and details (including doors and windows) should be preserved.
P. Landscaping And Screening: This section applies to all development. All developments containing significant vegetation as defined below shall comply with the standards of this section. The use of mature, native vegetation within developments is a preferred alternative to removal of vegetation and replanting.
1. Significant Vegetation: Individual trees with a trunk diameter ten inches (10") or greater, as measured four feet (4') above the ground (dbh), and all plants within the drip line of such trees and shrubs shall be protected.
a. Protection Standards: Significant trees, as identified in subsection P1 of this section, shall be retained whenever practicable. Preservation may become impracticable when it would prevent reasonable development of public streets, utilities, or land use permitted by the applicable land use district.
b. Construction: All areas of significant vegetation shall be protected prior to, during, and after construction.
c. Exemptions: Vegetation that is dead or diseased or poses a hazard to personal safety, property, or health may be removed. The applicant shall provide a report from a certified arborist or other qualified professional.
2. Landscape Area Standards: There is no minimum landscaping requirement. Landscaping shall be addressed in the site plan review process.
a. A combination of trees, shrubs, and ground covers shall be used for all planted areas, the selection of which shall be based on local climate, exposure, water availability, and drainage conditions. Nonnative invasive plants are prohibited.
b. Hardscape features (i.e., patios, decks, plazas, etc.) may cover up to ten percent (10%) of the required landscape area.
c. Trees shall be a minimum one and one-half inch (11/2") caliper at the time of planting.
d. Landscaping shall define pedestrian pathways and open space.
e. A combination of plants shall be used for year long color and interest.
f. Landscaping shall be used to screen outdoor storage and mechanical equipment areas.
4. Buffering And Screening:
a. Where a parking or maneuvering area is adjacent and parallel to a street, a decorative wall (masonry or similar quality material), arcade, trellis, evergreen hedge, or similar screen shall be established parallel to the street. The required wall shall provide breaks, as necessary, to allow for access to the site and sidewalk by pedestrians via pathways. Evergreen hedges used to comply with this standard shall be a minimum of twenty four inches (24") and a maximum of thirty six inches (36") in height at maturity, and shall be of such species, number, and spacing to provide the required screening one year after planting.
5. Street Trees: Street trees shall be planted for all development.
a. Trees shall be selected based on growth characteristics and site conditions, including available space, overhead clearance, soil conditions, exposure, and desired color and appearance.
b. All trees shall be a minimum one and one-half inch (11/2") caliper at the time of planting based on the American Association of Nurserymen Standards.
c. Street trees shall be placed in planting strips and in sidewalk tree wells on streets without planting strips.
d. Street tree spacing shall be based on the type of tree(s) selected. In general, trees shall be spaced no more than thirty feet (30') apart, except where planting a tree would conflict with existing trees, retaining walls, utilities, and similar physical barriers.
Q. Vehicle And Bicycle Parking: The purpose of this section is to provide basic and flexible standards for development of vehicle and bicycle parking. This section applies to all development. Parking shall be provided in accordance with the standards in chapter 6 of this title and the following additional standards:
1. Location Of Parking: Parking shall be located as follows:
a. No parking shall be located between the building and public streets, not including alleys.
b. No parking shall be located closer to a public street than the primary building on the property.
c. These standards may be modified through a conditional use review. In such cases, the planning commission shall consider the buffering and screening provisions of this chapter, and may require buffering, screening, low walls, landscaping, or other measures to reduce the visual impact of parking areas.
2. Maximum Parking: The maximum parking standard shall be one hundred twenty percent (120%) of the minimum. This standard is intended to ensure that parking areas that are out of scale with the zone district are not permitted outright.
3. Shared Parking: Required parking facilities for two (2) or more uses, structures, or parcels of land may be satisfied by the same parking facilities used jointly, to the extent that the owners or operators show that the need for parking facilities does not materially overlap (e.g., uses primarily of a daytime vs. nighttime nature), and provided that the right of joint use is evidenced by a deed, lease, contract, or similar written instrument establishing the joint use.
4. Mixed Use: If more than one type of land use occupies a single structure or parcel of land, the total requirements for off street automobile parking shall be the sum of the requirements for all uses, unless it can be shown that the peak parking demands are actually less (i.e., the uses operate on different days or at different times of day). In that case, the total requirements shall be reduced accordingly. (Ord. 925, 6-13-2005)
