"CHAPTER 29 ARTICLE 3
ZONING PROCESS
Sec.29.307. NONCONFORMITIES.
(5) Other Nonconformities.
Development that is consistent with a Site Development Plan approved before the date that this Ordinance became
effective shall be deemed to be in conformance with this Ordinance to the extent that it is consistent with the approved
plan and to the extent that such plan or conditions imposed thereon directly addresses the specific issue involved in the
determination of conformity. However, redevelopment of a site with a prior Site Development Plan approval must
conform to the current zoning standards for issuance of a new certificate of compliance.
(b) Policy.Because nonconformities such as those listed above involve less investment and are
more easily corrected than those involving lots,buildings and uses,it is generally the policy of the City to eliminate such
other nonconformities as quickly as practicable.Practicable improvements take in to account current conditions,planter
dimensions,building spacing and scope of improvements proposed for a property.Front yard landscaping,parking lot
landscaping and screening shall be reviewed in each instance where new or redevelopment is proposed with a Site
Development Plan.Although full compliance may not be achievable, all sites must advance towards compliance with
current requirements in terms of location of plantings and quantity of plantings.

(d) No area of the front yard landscaping shall count toward parking lot landscaping.
(e) Overstory shade trees must be planted at a rate of 1 tree for every 200 square feet of the
required 10%landscape area.Note that to meet the dispersal requirement for the parking lot,a site may need to exceed

See.29.403(5) ADMINISTRATION.
(A) Maintenance of Landscaping
The property owner shall maintain required landscaping in a healthy and vital condition.The property owner shall permit
and support the full maturity of required landscaping,including allowing for trees to reach their mature height and canopy
size by not prematurely pruning,removing,"topping,"or by other means discourage the growth and health of vegetation.
Dead or unhealthy vegetation shall be removed and replaced consistent with the standards of this ordinance. In kind
replacement is required within 60 sixty days of removal of dead or unhealthy landscaping.
(B) Failure to maintain landscaping and planters consistent with the standards of this ordinance is a
violation of the Zoning Ordinance. The Zoning Enforcement Officer may require replacement landscaping at larger
installation sizes as corrective action to improper landscaping maintenance or removal,in addition to the provisions of
Article XVI.
(C) Removal of Landscaping
(i) Property owners shall not remove existing vegetation that is consistent with an approved Site
Development Plan that may no longer be required under the current standards without providing for a whole site review
that includes replacement landscaping consistent with all new standards.For example, although side yard buffering is
not required in many commercial areas there are additional parking lot landscaping requirements that would need to be
addressed with a new landscaped plan before trees could be removed and have a compliant overall site.Existing trees
and shrubs cannot be removed without addressing how replacement landscaping that is consistent with current
requirements in terms of quantities, areas, quality, and types, will be added to a site to address current landscaping
requirements.Approved Special Use Permits must be amended by the Zoning Board of Adjustment if existing vegetation
is proposed to be removed and replaced.
(ii) Modifications to landscape plans may be submitted for Planning Director approval as a site
landscape plan rather than as a Site Development Plan. However, if there are changes to the planting areas that affect
stormwater management or are in conjunction with other changes to the site,a Minor Site Development Plan is required.
The Planning Director shall prescribe the landscape plan application requirements for modifications to existing
landscaping. The Planning Director may approve a modified landscape plan for existing sites when the overall
landscaping planting plan is consistent with the intent of the ordinance for overall site landscaping of parking lots,yards,
and screening and the modified plan is determined to not diminish the landscape qualities of the site.
(D) Installation and Inspections
(i) Landscaping shall be installed commensurate with the overall construction and phasing of
a site.Site Development Plan approvals may include conditions to facilitate planting of vegetation during the first phase
of construction for larger projects.
(ii) Prior to requesting occupancy of a building or actual use of a site,whichever occurs first,the
property owner or applicant must submit a report verifying that required planter requirements for soil quality and
conditions comply with the ordinance.
(iii) All required landscaping materials,both living and non-living,shall be in place prior to the
time of issuance of a final Certificate of Occupancy.The Zoning Enforcement Officer may grant a temporary Certificate
of Occupancy for use of a site or building when the property owner has agreed to complete the required plantings within
60 days of the request for occupancy or by October lst, whichever would occur first. The Planning Director may
authorize deferral of landscaping plantings for a specified period of time due to adverse weather conditions and subject
to the posting of a cash escrow or irrevocable letter of credit in an amount equal to one and one-half times the estimated
cost ofthe landscaping.Posting offinancial security for completing landscaping does not relieve the property owner from
installing and maintaining landscaping in accordance with the standards of this ordinance.
(iv) The property owner may be found to be in violation ofthe Zoning Ordinance at any time once
the initial delay for installation has been expired, whether a financial security has been provided or a Certificate of
Occupancy has been finaled by the Building Official.
Sec.29.405. OUTDOOR DISPLAY AND STORAGE.
(1) Outdoor Display of Goods.
(c) Auto and Marine Craft Trade outdoor display areas shall only be established on sites that

to increase landscape area within parking lots that exceed 30 or more spaces.
(d) The Planning Director may approve a reduction of up to three required parking stalls to
accommodate a vehicular cross-access route to an adjoining property.
(7) Locating Parking Spaces in Front Yard.
(a) Surface Parking Lot Landscaping Plan
Unless a parking lot plan is submitted as part of the development process pursuant to Section 29.1502,a Surface Parking
Lot Landscaping Plan to meet the standards of Section 29.403 and 29.406 shall be submitted to and approved by the
Director of Planning and Housing(to be evidenced by a document signed by both the property owner or owner's agent
and the said Director),prior to any construction,reconstruction,installation,erection,conversion,alteration,addition,
enlargement or development of any structure,improvement,feature or aspect of the premises.A Building/Zoning Permit
required by Section 29.1501 shall not be issued until the plan is submitted and approved.
(b) Front yard parking is permitted on commercial or industrial sites unless prohibited by the base
zone standards.
(13) Surface Parking Landscaping and Screening. Surface parking facilities must conform to the minimum
landscaping and screening requirements set forth in Section 29.403 unless it is a part of an approved Master Plan or a
Major Site Development Plan which City Council deems acceptable under the purposes of Section 29.403.
Sec.29.408. OTHER GENERAL DEVELOPMENT STANDARDS.
(4) Mechanical Units.
(b) Screening Exemptions. Screening of mechanical units is not required in the following
instances:
(iv) Sites with front yard landscaping as required within Section 29.403 and where
mechanical units are located behind the centerline of a building.Where front yard landscaping is not in place,screening
is required.
(c) Location of Mechanical Units
(i) Mechanical units must meet all screening requirements of Section 29.408(4)and
must be located outside of required landscape areas in parking lots or bufferyards.However,in situations where upgrades
or relocations of mechanical units for utility services are necessary to provide continued service,the Director of Planning
& Housing may approve placement of mechanical units in required landscape areas, and may also waive screening
requirements of mechanical units, if the Director determines that such upgrades or relocations could not have been
anticipated either at the time of platting or at the time of site development when the utilities were first planned and/or
installed, and that there is insufficient room for the relocated or upgraded utility mechanical units to be screened or
placed outside of required landscape areas.
Section Three. All ordinances,or parts of ordinances,in conflict herewith are hereby repealed to the extent of
such conflict,if any.
Section Four. This ordinance shall be in full force and effect from and after its passage and publication as
required by law.
