The purpose of this article is to place all of the use development standards in one place in as simple a format as possible. With the exception of the provisions of Articles II through XII pertaining to general standards applying in any district (home occupation and off-street parking and loading) and general provisions relating to special situations in any district (accessory uses, nonconformities, earth removal and filling and grading, unusual height and yard situations and utility service provisions), along with shoreland zoning provisions, all of the use development standards are contained in this one article.
Numerical standards, height and density concepts,
yard requirements and other measurements of development, bulk or intensity
need to be clearly understood if such standards are to be properly
applied. This section explains the following terms used in the tables
in this article.
A.
Height limits. Height limitations are established
by three factors which define a building envelope for a lot in the
specific district:
[Amended 12-11-2000 by Ord. No. 01-42; 5-10-2004 by Ord. No. 04-125]
(1)
Maximum district height: the maximum limit on height
at any point on a lot in any part of the district.
(2)
Maximum building height at minimum yard setback line:
(a)
Front yard: is equal to minimum setback dimension.
(b)
Side yard: is equal to two times the minimum
side yard dimension.
(c)
Rear yard: is equal to minimum rear yard dimension.
(d)
Where a setback is less than 20 feet, maximum height at setback
line is 20 feet.
[Amended 4-24-2017 by Ord. No. 17-135]
(3)
Maximum height within buildable area is equal to maximum
building height at minimum yard line, plus one foot above building
line maximum for each additional foot distance from the property line,
up to the district maximum height (as prescribed in the district regulations).
(4)
The maximum building height limitation at the minimum
yard setback line shall not apply in the Downtown Development District,
Bass Park District, Airport Development District or Waterfront Development
District.
[Amended 4-11-2011 by Ord. No. 11-100]
(5)
The building envelope sketch below illustrates the
interaction of these three factors on height control.

B.
Floor area ratio. "Floor area ratio" (FAR) is the
maximum that the ratio of building gross floor area divided by lot
area (for a given lot) cannot be exceeded for that use or district.
C.
Impervious surface ratio (ISR). The "impervious surface
ratio" is the maximum percent of surface area of a lot or site which
is not to be loamed, reseeded or revegetated after construction of
site development project.
D.
Buffer yard.
(1)
A "buffer yard" is a designated area along the rear and side yards of a site development which is to be planted and landscaped in a certain manner (or alternative manners) to lessen the impact of one site development upon another. The buffer yard requirements are shown in 100-foot-long units. Lots with a yard of less than 100 feet in length will be required to provide buffer yard elements in proportion to the 100-linear-foot requirements indicated below. All fractions of trees or shrubs will be considered whole plants. There are five different types of buffer yards which may be required under Article XIV: Buffer Yards A, B, C, D and E, as defined by the illustrations which follow.[1]
[Amended 4-9-2007 by Ord. No. 07-97; at
time of adoption of Code (see Ch. 1, General Provisions, Art. I)]

Editor's Note: Buffer yard illustrations are included as attachments to this chapter.
(2)
Minimum standards for buffer yard trees and shrubs.
All plants in prescribed buffer yards will meet the following minimum
standards:
[Amended 4-9-2007 by Ord. No. 07-97]
(3)
Plant spacing.
[Added 4-9-2007 by Ord. No. 07-97]
(a)
The following guideline should be considered
in spacing of adjacent plants by type:
|
Type
|
Mature Width
(feet)
|

(feet on-center)
|
|---|---|---|

|
|
Large shrubs
|
10 to 30
|

|
|
Small shrubs

(b)
Grouped planting beds are encouraged, but plant
materials should not leave an unscreened opening greater than 25 feet
when measured at tree canopies at 50% of full growth.
(4)
Substitutions.
[Added 4-9-2007 by Ord. No. 07-97]
(a)
Existing vegetation may be preserved and maintained
to meet the applicable buffer yard, provided the vegetation is of
a type and variety to mix the mix of plants for specific buffer yards.
Applicants may also enhance existing vegetation to meet the range
of types required in specific buffer yards.
(b)
Parking lot buffers may substitute a landscaped
berm for six shrubs, provided that the berm is a minimum of three
feet higher than the elevation of the adjacent parking lot being buffered.
(c)
Transition yard buffers may substitute a minimum
six-foot opaque fence for eight shrubs.
(d)
Landscape boulders that are a minimum of 48
inches tall by 48 inches wide may be substituted for up to 50% of
the required shrubs.
(e)
A minimum three-foot stone or masonry wall may
be substituted for 10 shrubs.

No. 21-098]
