purpose of this
M-R district is
to enable innovation and flexibility in
design and to promote environmentally sound and efficient use of land.
The major objectives of
an M-R district are:
allow certain research, development and office park uses in locations where a broad
range of uses might be inappropriate
encourage development of such scale and character that it will be harmonious with
surrounding areas and minimize any adverse impacts
Permitted uses. In district M-R, no building, land or premises shall be used and no
building shall hereafter be erected, constructed, reconstructed or altered except for one or more
of the following uses allowed by the ordinance placing the property in District MR (for
exceptions, see Section 2928, NonConforming Uses, and Section 2931, Board of Adjustment).
The Commission shall recommend and the Council, at the time of rezoning, shall designate the
use or uses allowed for the applicants property from the following uses:
One or more or all of the permitted uses in District MC
One or more or all of the permitted uses in district C-1.
All uses and processes shall be conducted entirely within enclosed buildings.
Conditional Uses. The following uses shall be permitted in district M-R only after
issuance of a conditional use permit pursuant to the provisions of section 29-23:
Churches, mosques, and synagogues, subject to the following
(1) The conditional use permit shall be valid for a period
not to exceed five (5) years.
Renewal of the conditional use permit shall be treated as a new request for a conditional use
(2) A site plan shall accompany the conditional use permit
application, showing that parking
will be provided for the church and any other associated uses in accordance with Section 29-30.
Standards and Criteria. The following standards and criteria shall apply to all M-R
(1) Lot size. No minimum requirements.
Yards. Yards shall be provided as
a. Front - Not less than twenty-five (25) feet from collector and arterial streets
and fifteen (15)
feet from all other streets.
b. Rear - None, except not less than ten (10) feet when abutting a residential
c. Side - None, except that:
1. On corner lots the side yard shall be not less than twenty-five (25) feet
adjacent to collector
and arterial streets and not less than fifteen (15) feet from all other streets, and
2. The side yard abutting a residential zoned district shall not be less than
ten (10) feet.
Building height. No specific maximum; however,
there shall be one additional foot of
rear yard and interior side yard setback provided above the required minimum for each additional
foot of height for buildings over 45 feet tall abutting a residential zoned district. The
applicant may request or the commission may recommend and the council may approve a greater
maximum building height
(4) Vision clearance. On any corner
lot no wall, fence, sign or other structure or no plant
growth of a type which would interfere with traffic visibility across the corner shall be permitted
or maintained higher than three (3) feet above the curb level, within fifteen (15) feet of the
intersection of the street right-of-way lines.
(5) Parking and loading. The provisions
of Section 2930, OffStreet Parking and Loading,
shall apply, except that the Commission may approve a
parking requirement if, after
considering the proposed use, the availability of other parking in the area (including parking on
public streets) and other relevant factors, a
requirement is deemed appropriate.
The commission may also recommend and
the council may allow some of the required
parking to be deferred. This shall be done by noting such parking spaces on the plan as future
parking if needed. The future parking spaces may be placed within landscaped areas, as long
the landscaped areas are in excess of the 15% minimum of the site which is required to be in
landscaping. The property owner shall establish additional parking spaces in the future
parking area when directed to do so by the city council.
and landscaping. The provisions of Sec. 29-25 shall apply
a. A permanent screen consisting of a
masonry wall, wood fence, landscaping material, or
combination thereof, at least eight (8) feet in height and, when a fence is used, not to exceed
eight (8) feet in height, shall be required where a lot in this district abuts residentially zoned land.
The required screening shall have an opacity of at least eighty (80) per cent year around and, if
landscaping is used, the eighty (80) per cent opacity and eightfoot minimum height shall be
achieved within four (4) full growing seasons. In the event a masonry wall or wood fence is used,
landscaping shall be placed between the wall or fence and the property line to form an
ornamental screen. The required screening and landscaping shall be maintained in good order

landscaping and screening shall be considered a violation of this chapter.
b. All exterior storage areas shall be
enclosed by a permanent screen at least eight (8) feet in
height above the ground surface of the storage area. In the event that an eightfoot screen is
inadequate to screen such an area, additional screening may be required in such a manner and of
such materials as necessary to adequately screen such from public view. However, in no event
shall the screen exceed twelve (12) feet in height, except for landscape materials.
In no event

of the required
screening. The required screening shall have an opacity of at least eighty (80) per cent year
around, and if landscaping is used, the eighty (80) per cent opacity shall be achieved within four
(4) full growing seasons. When a solid wall, or any solid fence is used for screening, ornamental
landscaping shall be placed between the fence and the adjacent property lines. The required
screening shall be maintained in good order and not allowed to exist in a state of disrepair or
death. If wood fencing is used, it shall be durable in nature or treated to prevent rapid
deterioration. Failure to maintain the required screening shall be considered a violation of this
c. Exterior storage areas shall have a permanently dustfree
applicant may request or the
commission may approve less stringent screening

association or abutting property owners. No private streets shall be dedicated to nor accepted
the city for maintenance until they have been improved to minimum city standards for public
f. The street signs for private streets shall indicate private street
so as to distinguish them
from public streets.
Provisions shall be made for pedestrian travel within the development and shall connect

development and the developer to discuss land use and development
concepts, applicable regulations, and other concerns that may be raised.
The second step shall be the submission of a request for rezoning to M-R.
