A.
The purpose of design review is to exercise aesthetic judgment over
development projects within the city in order to maintain the desirable
character of the community. The community character is defined by
having charm in the design of buildings, keeping buildings small in
scale, honoring the beauty and ecology of the city's natural
setting, and recognizing that the arts are an integral part of the
community.
B.
This broad purpose is furthered by the following specific purposes
of design review:
1.
To implement the goals and policies of the comprehensive plan;
2.
To foster development that is designed, arranged and constructed
in a manner that provides a safe, efficient and aesthetically pleasing
community asset;
3.
To encourage originality and creativity in site design, architecture
and landscape design;
4.
To ensure that the arrangement of all functions, uses and improvements
of a development reflect the natural capabilities and limitations
of its site and adjacent property;
5.
To encourage development where the various structures, use areas
and site elements are integrated in a manner that is visually harmonious;
6.
To ensure that development maintains and strengthens the city's
sense of place which is defined by its location adjacent to the Pacific
Ocean, Ecola Creek, and the surrounding mountains; and
7.
To encourage landscape design which complements the natural
landscape, improves the general appearance of the community, and enhances
specific elements of the built environment.

2.
Prior to the design review board meeting, the applicant will
have clearly marked the corners of proposed buildings and other significant
features proposed for the site.
(Ord. 24-05, 6/5/2024)
To ensure that the stated purposes of the design review process are met, the design review board shall be governed by the criteria of Sections 17.70.070 through 17.70.100 as they evaluate and render a decision on a proposed design review plan.
(Ord. 24-05, 6/5/2024)
A.
The design review criteria are intended to provide a frame of reference
for the applicant in the development of site, building and landscape
plans, as well as providing the city with a means of reviewing proposed
plans. These criteria are not intended to be inflexible requirements,
nor are they intended to discourage creativity. The specification
of one or more architectural styles is not intended by these criteria.
B.
The design review board is not authorized, as part of the design review process, to approve projects which exceed specific development standards provided for by the zoning ordinance (e.g., building height or building setback), except the design review board may approve proposals exceeding the lumen limits in Section 17.70.130 provided that all exterior lighting on the subject property is either: (1) fully shielded relative to all adjoining residentially-zoned property; or (2) fully compliant with the maximum backlight/uplight/glare standards in Section 17.70.130 Table B.
C.
Potential full development of a site based solely on the standards
of the zoning ordinance (e.g., building height, building setback,
number of permitted motel units) may be inappropriate for a given
site. It is for this reason that the design review board is specifically
delegated the discretion, through the application of the design review
criteria, to require building or site designs which may or may not
result in the potential full development authorized by the zoning
ordinance.
D.
The design review board, in making its determination of compliance
with the design review criteria, shall consider the effect of their
action on the availability and cost of needed affordable housing.
The design review criteria shall not be used to exclude needed affordable
housing types. However, this consideration shall not prevent the imposition
of conditions necessary for a proposal to conform to the design review
criteria. The costs of such conditions shall not unduly increase the
cost of housing beyond the minimum necessary to achieve the purposes
of this chapter. The design review board shall have no authority to
affect dwelling unit density.
(Ord. 24-05, 6/5/2024)
The following criteria shall be used in evaluating site development
plans. The number adjacent to the criterion represents the relative
importance of that criterion, with "3" being the most important:
A.
The arrangement of all functions, uses, and improvements has been
designed so as to reflect and harmonize with the natural characteristics
and limitations of the site and adjacent sites (x3).
B.
In terms of setback from the street or sidewalk, the design creates
a visually interesting and compatible relationship between the proposed
structures and/or adjacent structures (x3).
C.
The design incorporates existing features such as streams, rocks,
slopes, vegetation (i.e., making use of a small stream rather than
placing it in a culvert) (x3).
D.
If the project is unusually large, or if it is located so as to become
part of an introduction/transition to the city or to a particular
district or to the beach, the design acknowledges the special impact
the project would have on the entire community by addressing these
design criteria in an exemplary, standard-setting manner (x3).
E.
Where appropriate, the design relates or integrates the proposed
landscaping/open space to the adjoining landscaping/open space in
order to create a pedestrian pathway and/or open system that connects
several properties (x2).
F.
The arrangement of the improvements on the site do not unreasonably
degrade the scenic values of the surrounding area (x2).
G.
The improvements on the site enhance and/or do not deny solar access,
light, or air within the site or to adjacent sites or structures (x2).
H.
Where appropriate, the design includes a parking and circulation
system that encourages a pedestrian rather than vehicular orientation,
including a separate service area for delivery of goods (x2).
I.
The arrangement of the improvements on the site does not unreasonably
block or greatly degrade scenic vistas enjoyed from neighboring (especially
public) sites (x2).
J.
The various functions and elements of the site design have been integrated
into a unified whole, except in those cases where separation is appropriate.
The overall design is visually harmonious when viewed either from
within the site or from outside the site (x2).
K.
The design gives attention to the placement of storage or mechanical
equipment so as to screen it from view (x1).
L.
If the project is adjacent to, or visible from, US Highway 101, the
design minimizes its visual impact on the scenic character of Highway
101 (x1).
M.
The arrangement of functions, uses and improvements on the site have
been designed to provide access to and within the site for individuals
with disabilities (x1).
(Ord. 24-05, 6/5/2024)
The following criteria shall be used in evaluating architectural
designs. The number adjacent to the criterion represents the relative
importance of that criterion, with "3" being the most important:
A.
The design avoids either monotonous similarity or excessive dissimilarity
with existing structures, or structures for which a permit has been
issued, in its section of town (i.e., downtown, midtown, etc.). If
the development includes multiple structures, the design avoids either
monotonous similarity or excessive dissimilarity between the component
structures (x3).
B.
The size, shape and scale of the structure(s) are architecturally
compatible with the site and with the surrounding neighborhood. The
structure is sufficiently modest in scale to enhance the village character
of the community(x3).
C.
The proposed materials and colors are compatible with the character
and coastal setting of the city (x3).
D.
The design avoids monotony and provides visual interest and charm
by giving sufficient attention to architectural details and to such
design elements as texture, pattern, and color (x3).
E.
If the project includes a large structure or structures, such as
a large motel or condominium, the design avoids a monolithic expanse
of frontages and rooflines and diminishes the massing of the buildings
by breaking up building sections, or by the use of such elements as
variable planes, projections, bays, dormers, setbacks, or changes
in the roofline (x3).
F.
If the project is unusually large, or if it is likely to become a
village landmark, or if it is located so as to become part of an introduction/transition
to the city or to a particular district or to the beach, the design
acknowledges the special impact the project would have on the entire
community by addressing the design criteria in an exemplary, standard-setting
fashion (x3).
G.
The height of the structure(s) is architecturally compatible with
the site and the surrounding neighborhood. The height of the structures
contributes to the village scale (x2).
H.
The height of the structure(s) is such that it does not unreasonably
destroy or degrade the scenic values of the surrounding area (x2).
I.
The height of the structure(s) is such that it does not unreasonably
block or greatly degrade the views of scenic vistas as seen from neighboring
sites (x2).
J.
The height of the structure(s) is such that it does not unreasonably
deny solar access, light, or air to an adjacent structure, on or off
the site (x2).
K.
The design sufficiently addresses the relationship of the structure(s)
to the sidewalk and to pedestrian activity so as to foster human interaction
(x2).
L.
The proposed signage harmonizes with the other structures in terms
of form, materials, and scale (x2).
M.
Lighting fixtures: (1) are compatible with the architectural design; (2) produce illumination sufficiently subdued to be compatible with the village character; (3) avoid casting glare on adjoining property; (4) are sufficient for night-time safety, utility, security, and commerce; and (5) do not exceed the illumination values in the table at Section 17.70.130 (x2).
N.
The project incorporates design elements or building improvements
which result in the conservation of energy (x2).
O.
The design of the project ensures continued privacy for the occupants
of adjacent structures (x1). In cases of multifamily housing, this
item is to be rated as x3.
(Ord. 24-05, 6/5/2024)
The following criteria shall be used in evaluating landscape
plans. The number adjacent to the criterion represents the relative
importance of that criterion, with "3" being the most important:
A.
The design substantially complements the natural environment of Cannon
Beach and the character of the site (x3).
B.
The design harmonizes with and enhances the architectural design
(x3).
C.
The landscape design acknowledges the growing conditions for this
climatic zone and the unique requirements that its specific site location
makes upon plant selection (i.e., salt, wind and wind exposure, soil
condition, light, shade, etc.) (x3).
D.
Provision has been made for the survival and continuous maintenance
of the landscape and its vegetation (x3).
E.
Where it is desirable to do so, the design provides amenities for
the public (x3).
F.
The design makes use of existing vegetation and incorporates indigenous
planting materials (x2).
G.
The selection and arrangement of plant materials provides visual
interest by the effective use of such design elements as color, texture
and size differentiation (x2).
H.
The hard surface portion of the design makes use of visually interesting
textures and patterns (x2).
I.
Where it is desirable to do so, the design provides visual interest
through the creation of a variety of elevations (x2).
J.
The design contributes to the stabilization of slopes, where applicable
(x2).
K.
The design successfully delineates and separates use areas, where
it is desirable to do so (x2).
L.
The lighting fixtures and level of illumination are compatible with
the landscape design. The level of illumination produced enhances
the overall project and does not cast glare on adjacent property or
into the night sky (x2).
(Ord. 24-05, 6/5/2024)
Construction documents (i.e., drawings and specifications) shall
conform to all aspects of the approved design review plan. Where circumstances,
unknown or unforeseen at the time the plans are approved, make it
undesirable or unfeasible to comply with some particular aspect of
the approved plan, the applicant shall request in writing that the
city review the modification. The city manager and the chair of the
design review board shall review the proposed modification to determine
whether it constitutes a "major" or "minor" revision of the approved
plans.
A.
B.
Minor Modifications.
1.
Minor modifications are those which result in an insignificant
change in the approved plan.
2.
The following are examples of minor modifications:
3.
If the city determines that the proposed change is a minor modification,
the city will proceed with the review of the construction documents
or changes in construction.
