City Zoning Ordinance Amendments
City Council
July 1, 2008
Background:
Current CZO provisions were adopted in 1990, when
cell phone usage (and the number of towers needed
to support that usage) was much lower than it is
today.
In late 2007, the City Council asked Staff to ensure
that new wireless telecommunications equipment is
located on sites where there are existing towers or
where there is an existing structure that can
accommodate additional antennas without the need
for a new tower (“co-location”).
Background, con’t
Where co-location is not reasonable or possible
and a new tower is needed, the City Council
wanted to make sure that alternative sites are
investigated, such that the tower is constructed
in a location that is as visually unobtrusive as
possible
Background, con’t
Staff worked with wireless telecommunications
providers to develop an ordinance that would
accomplish these goals and improve the current
siting process.
The Planning Commission considered the proposed
ordinance in June and recommended approval with
a few changes. There was no opposition to the
ordinance.
Although the proposed ordinance repeals the
entire current section 232 of the CZO and
rewrites that section, most of the existing
provisions are kept intact. Other provisions
are added and the section has been
reorganized.
NEW PROVISIONS
Purpose (Lines 251-262):
•Facilitate provision of wireless services to citizens and
businesses
•Minimize risk of physical damage and other potential
adverse impacts
•Require joint use of towers where commercially reasonable
•Allow use of public property where such use (i) minimizes
potential adverse impacts; (ii) does not adversely affect
public facilities; and (iii) meets applicable requirements
pertaining to use of public property

New Provisions, con’t
Preapplication Conference (Lines 264-285):
Applicant MUST meet with Staff prior to filing of
?
application to discuss:
-Co-location on existing tower or other structure, incl. a public
facility;
-Availability of suitable alternative sites, incl. public sites;
-Specific issues (e.g., potential interference with public safety
communications facilities, visual and other potential impacts on
nearby property & means of eliminating impacts);
-Feasibility of camouflaging equipment (“stealth technology”); and
-Any other relevant matters

wmm1 it is anticipated that the pre-application conference will resolve most if not all of the issues before the application is ever filed

New Provisions, con’t
Application Requirements (Lines 290-397)
Report from professional engineer re proposed tower
?
height, design, etc. must be under seal
?Where proposed tower is within ¼mile of a residential
or apartment district, application mustbe supplemented
no later than 30 days prior to Planning Commission
meeting by:
Balloon tests, photo simulations & other
?
information Planning Dir. deems necessary to
assess visual impact;
?Summary of planned contacts with nearby
residents and of actual contacts when they occur
Application Requirements, con’t
?Applicant must also submit verifiable specificinformation
regarding lack of available space or structural capacity for the
applicant's equipment on (i) existing towers, buildings or other
structures, (ii) sites on which existing towers are located, or (iii)
sites on which the proposed tower would be less visible
from or located a greater distance from residential or
apartment districts than the proposed location
?Note (i) and (ii) are in current ordinance; (iii) is new.
?If tower is within 1 mile of an existing or planned public
safety communications facility, an intermodulation study is
required (to determine if the proposed equipment will interfere
with public facility)
Application Requirements, con’t
Also required:
?Map showing that equipment will not be within
200-foot buffer of microwave path between
public safety communications sites
?Water tanks: security plan re access by non-
City personnel (unless plan is in the lease)
Location & Design Requirements (Lines 399-440)
City Council shall give primary consideration to:
1.Whether proposed equipment cannot be located on an
existing or approved tower because:
?Proposed equipment would exceed height or
structural capacity on the other tower and other
tower cannot be modified (as documented by
licensed P.E.);
?Proposed equipment would cause electromagnetic
interference with other existing or approved sites
and interference cannot be prevented;
?Existing or approved tower not high enoughfor
coverage
Location & Design Requirements, con’t
2.Co-location capacity of proposed tower
-at least 2 other users if height is > 100’, 1 other user
if height is < 100’
3.Whether proposed application conforms to requirements
re public safety sites and water tanks (see below)
4.Applicant’s written agreement to allow co-location on
commercially reasonable terms
Landscaping Requirements (Lines 450-486)
?Existing trees within the area under control of the
applicant (leased area) shall be preserved to the
extent practicable
?Towers shall be located on the site so as to maximize the
effectiveness of trees as screening (as permitted by
setbacks)
?Existing landscaping may be used to satisfy requirements
?City Council may modify landscaping requirements as it
deems appropriate (either more or less landscaping)
Setback Requirements (Lines 488-507)
?Same as current ordinance, but City Council may
require greater or lesser setbacks as needed to
protect existing or future structures from damage
or to enhance screening effect of trees on or off
the site
Public Safety Communications Sites/Water Tanks
?Special considerations apply to these sites (security and
public safety/emergency use), so there are add’l
requirements applicable to them
?No private telecom facilities allowed:
-on sites with PSC facilities;
-in any location where intermodulation study
shows there would be a substantial possibility of
interference with PSC communications that
cannot be satisfactorily mitigated; or
-within 200-foot buffer of microwave path of an
existing or future PSC microwave facility
Public Safety Communications Sites/Water Tanks, con’t
No private telecom facilities on water tanks or within
secure areas unless there is a demonstrable public need
in the area and no reasonable alternative site is
available.
If allowed, applicant must comply with security plan as a
condition of the CUP
Other New Provisions
Communication towers on electric transmission line
structures and building-mounted antennas allowed
without CUP if:
-they match color of structure on which they are
mounted
-Communication towers no higher than 20%
above structure;
-Building-mounted antennas in least visible
location practicable or otherwise screened from
view (note BMAs are currently allowed by right in most
zoning districts); and
-APOs are notified of new communication tower
Other New Provisions, con’t
?Any tower or other wireless equipment not used for 1 year
shall be removed within 90 days after notification. If not
removed, City contract for removal and charge the cost to the
tower/equipment owner
Open issue -communication towers in P-1
Preservation District
Staff version prohibited (i.e., no CUP allowed) on P-
1 land that is undeveloped and in its natural state,
but allowed on other P-1 land (e.g., neighborhood
parks).
Planning Commission recommendation is to allow
them with CUP everywhere in P-1.
