[CC 1990 § 31-04-02; Ord. No. 2801 § 3 (Exh. A), 6-16-2014]
A.
Purpose And Intent. The purpose of this Section of the City
of Chesterfield UDC is to provide a detailed guide for the preservation
and planting of trees within the City of Chesterfield. Tree preservation
and planting in the City of Chesterfield represents an on-going effort
to maintain the character and benefits derived from trees. Whether
trees exist as a natural occurrence of native tree species or as planted
trees around existing developments, their protection can only be assured
when tree protection measures are utilized. By selecting the trees
that will be preserved before the final stages of development, tree
protection design standards can be created and included prior to the
early stages of development of the site. Planting of new trees should
be used to supplement a site's existing landscaping, not replace it.

A.
Purpose.
1.
The purpose of this Section is to provide minimum standards
for effective, economical, and attractive outdoor lighting. It is
the intent of this Section to:
B.
Applicability.
1.
These regulations shall apply to all outdoor lighting including
residential, and all jurisdictions, including public, private, and
municipal, except as provided elsewhere in this Article.
2.
Single-family residential lots shall be exempted from this Section of Code; however, nothing in this Section shall be construed to exempt single-family lots from complying with Chapter 215, Nuisances.
3.
All required lighting installations must be regularly maintained
(cleaned, repaired, etc.), such that they always provide acceptable
luminance levels and glare control.
C.
Architectural Specialty Lighting Package Submittals.
1.
The purpose of an architectural specialty lighting package is
to provide comprehensive, complementary and unified architectural
specialty lighting throughout a single development or contiguous lots
under common ownership. If an architectural specialty lighting package
exists for a multi-lot development or subdivision, then individual
lots within that subdivision or development may not submit their own,
separate architectural specialty lighting package. In addition, developments
of a certain size, quality, or mix of uses may require special architectural
specialty lighting consideration. Therefore, in order to encourage
superior design, quality and character, comprehensive architectural
specialty lighting packages allow for specialized review of architectural
specialty lighting and flexibility from standard site lighting requirements.
An architectural specialty lighting package is not required for traditional
architectural accent lighting applications or for residential applications,
as determined by the Director of Planning. Seasonal holiday displays
are exempt from the architectural specialty lighting package regulations.
2.
Architectural specialty lighting should highlight and accentuate
traditional building detailing and architectural features.
3.
The color temperature of architectural specialty lighting should
underscore the building materials and character.
4.
When non-traditional lighting color is requested, changes in
color shall be limited to one (1) change within any twenty-four (24)
hour time period. Modifications to this standard shall require a two-thirds
(2/3) vote of the Planning Commission.
5.
Precise lighting applications should highlight distinctive architectural
features.
6.
All proposed light fixtures should be permanently mounted.
7.
Architectural specialty lighting should be unobtrusive in intensity
and should not turn a building into an attention-getting device or
blanket signage.
8.
Architectural specialty lighting shall not interfere with or
obscure the public's capacity to receive information, or cause visual
confusion by interfering with pedestrian or vehicular traffic. Architectural
specialty lighting shall conform to the character of the community,
enhance the visual harmony of development, and preserve the public
health, convenience, welfare and/or safety within the City of Chesterfield
by maintaining the high aesthetic quality of the community.
9.
When an architectural specialty lighting package is requested
for a proposed or existing development, the criteria for site lighting,
as provided for in this Article, may no longer be applicable in its
entirety or portions thereof. The reason for the requested modification
is to provide for flexible architectural accent lighting criteria
that promotes superior design, and is tailored to a specific development
which may vary from general ordinance provisions.
10.
Consideration of flexibility in architectural specialty lighting
criteria is based on a number of review factors, including, but not
limited to, the physical impact of the proposed architectural specialty
lighting package, the quality of the proposed architectural specialty
lighting package, and mitigation of unfavorable conditions such as
excessive lighting, light spillover, height, and other related conditions
and potentially negative impacts. However, in no instance shall architectural
specialty lighting applications result in light trespass at the property
line.
11.
When an architectural specialty lighting package is requested
for a development, the following shall be submitted to the Department:
a.
A narrative detailing the reasoning for the architectural
specialty lighting package request and why it will enhance the proposed
development above what would be permitted through the City of Chesterfield
UDC. The narrative shall address how the proposed architectural specialty
lighting is architecturally integrated with the building style, materials,
and color.
b.
The narrative shall include a description of the
location, illumination level, color, dimensions, mounting height,
construction material, hours of use, nature (static, shifting, flashing,
blinking, animation, graphics, light patterns, etc.), frequency and
duration of lighting shifts/changes, brightness, and type of all proposed
architectural accent lighting fixtures.
c.
Detailed, high-resolution, color elevations drawn
to scale of all structures containing proposed architectural specialty
lighting fixtures.
d.
Night view perspectives or renderings.
e.
Photographs of all existing architectural specialty
lighting fixtures.
f.
Lighting plans indicating the location of all standards
and fixtures and the proposed type of illuminating devices, fixtures,
lamps, supports, reflectors, and other devices as well as three-dimensional
photometric elevations denoting foot-candle levels on all impacted
building elevations and adjacent ground areas.
g.
A cut sheet will be required for each proposed fixture
and associated shielding.
h.
Where shielding is not provided in conjunction with
the proposed light fixture, information indicating that no light trespass
or sky glow will result from the requested fixture is required.
i.
Photographs of similar installations or building
applications.
j.
Photographs of adjacent properties.
k.
Other information as required by the City of Chesterfield.
12.
Upon review by staff and after receiving recommendation from
the ARB, architectural specialty lighting packages shall be submitted
to the Planning Commission for review and consideration.
D.
Site Lighting. Site lighting shall be designed to provide the minimum lighting necessary to ensure adequate vision and comfort in parking areas, and to not cause glare or direct illumination onto adjacent properties or streets. The Director of Planning shall approve exterior light fixtures and usage after submittal of items as delineated in Subsection (G) demonstrate compliance with the standards set forth in this Section.

and lighting used for signage shall be subject to the approval of
the Department.
6.
Parking area lighting shall be designed and installed so as
to achieve the illumination levels set forth in Table 3, below. Lighting
shall be maintained so as to achieve not less than eighty percent
(80%) of the minimum illumination level set forth by the following
Table 3.
7.
The facades of buildings facing I-64/US 40 should utilize accent
lighting, as opposed to flood lighting. All lighting shall be mounted
at a maximum height of thirty (30) feet.
8.
The Director of Planning may permit lighting arrangements exceeding
the maximum initial level set forth in Table 3, below, to allow lighting
designs which substantially exceed the required minimum and average
illumination levels. Any plan exceeding the levels below should be
accompanied by a statement from a qualified lighting designer providing
industry standards and information substantiating the requests.

b.
Ensure that adequate off-street parking and loading
facilities are provided for new land uses in proportion to the need

1.
The Director of Planning shall determine the off-street loading
space requirements for a use not specified, based upon the most similar
use listed in the preceding minimum parking requirements tables or
using certified service/goods handling data for the specific use.
2.
In calculating the required number of loading spaces, fractional
spaces are rounded to the nearest whole number, with one-half (1/2)
counted as an additional space.
F.
Schedule Of Off-Street Drive-Through Stacking Requirements.
Off-street drive-through stacking spaces shall be provided, at a minimum,
in accordance with the following schedule and shall not interfere
with vehicular or pedestrian circulation, or parking on the site.
Where stacking space is provided in a single stacking lane, the stacking
requirement shall be calculated as the sum of the requirement for
each feature that requires stacking.
1.
Car Wash.
a.
Full service: one (1) space at each vacuum or wash
station, plus four (4) additional stacking spaces for each wash bay
lane.
b.
Self-service (drive-through/automated): one (1)
space in the wash bay, plus three (3) additional stacking spaces for
each wash bay lane.
c.
Self-service (open bay): one (1) space per vacuum
or wash bay, plus two (2) additional stacking spaces for each wash
bay lane.
3.
Financial Institution.
a.
One (1) space at each drive-up service lane, plus
five (5) additional stacking spaces for each service lane where there

G.
Joint Parking. All parking spaces required by this UDC shall
be located on the same parcel of land as the use to be served except
as follows:
1.
Parking for one (1) or more uses in a commercial or industrial
district may be provided on a separate lot when said separate lot
is within a similar zoning district type and within four hundred (400)
feet of the use or uses to be served, as measured along a pedestrian
walkway designed to allow pedestrians to safely access the use.
2.
When two (2) or more owners agree to provide their required
parking spaces jointly, the number of joint parking spaces shall be
equal to the number of parking spaces required if each were to provide
parking separately, unless otherwise stated in this Section.
a.
The applicants for joint parking shall submit a
joint parking plan and an appropriate legal instrument of agreement
among the involved property owners for review by the Director of Planning.
b.
Such joint parking plan and agreement shall include
language binding the owners of the properties and their successors
and assigns to the agreement and limiting and controlling use of land
to those uses and conditions accepted by the Director of Planning
and agreed to by the owners of the properties involved.
c.
If the joint parking plan and agreement are found
to conform to the requirements of applicable codes, laws, and ordinances,
they shall be stamped accepted by the City of Chesterfield and returned
to the applicant. The applicant shall record these accepted documents
with the County Recorder of Deeds. Recorded copies of the accepted
documents shall be provided to the City of Chesterfield prior to release
of municipal zoning approvals (MZAs) associated with the joint parking
plan and agreement.
H.
Deferral Of Parking Construction. An applicant may request to
defer the construction of the number of required parking spaces during
the site plan, site development concept plan, site development section
plan, or site development plan review process. A parking deferral
means that some of the required parking spaces would not be provided
until full build-out occurs, but that an area on the site would be
reserved so that these spaces could be provided in the future upon
demand or request by the City. Said demand would be made if the spaces
were needed to meet the parking needs of the project.
1.
Criteria For Parking Deferral. The Director of Planning may
grant a deferral for construction of up to fifty percent (50%) of
the off-street parking spaces required by this Section in an industrial
district; thirty percent (30%) in a commercial district and any other
district if an applicant demonstrates:
a.
Trip generation characteristics and time of day
usage characteristics for similar uses show that the parking spaces
can be reduced without causing parking to overlap into other nearby
developments or onto public streets.
b.
Vehicles owned by the occupants are characteristically
different from the norm, or the proximity to employment, shopping,
educational and transit developments is such that reduced auto usage
would be anticipated.
c.
The immediate proximity to public transportation
facilities serves a significant proportion of residents, employees,
and/or customers.
d.
Operation of effective private or company car pool,
van pool, bus or similar transportation programs with proof of continued
financial viability.
e.
Evidence that a proportion of residents, employees,
and/or customers utilize, have available or on a regular basis use
bicycle or other transportation alternative commensurate with reduced
parking requirements.
f.
Development will be in phases so that deferring
the parking will have green space until further build-out. The site
must meet all parking requirements based upon square footage actually
built.
2.
Application. Applicants for deferral of parking shall provide
a written statement which addresses how the proposal meets the applicable
criteria. The application shall include a site plan depicting the
total required parking on-site, and the deferred parking area shall
be labeled as reserved for future parking.
3.
Landscaping. The land area delineated for deferred parking shall
be shown on the plan with proposed finish grades and landscaping.
Landscaping for the deferred parking area shall be as approved by
the Director of Planning with the remainder of the site landscaped
per City of Chesterfield Landscape Guidelines for the appropriate
district. All landscaping shall be indicated on the plan submitted.
4.
Notice Of Change Of Condition. The owner of the property, or
his/her designated party, shall notify the City of any change in the
conditions that were the basis for a deferral.
5.
Construction Of Deferred Parking Areas. The City may require
the construction of parking in areas previously reserved at any time
upon sixty (60) days' written notice. A parking deferral shall apply
to the developer and all subsequent owners of said property and shall
run with the land and be shown on all recorded plats. The plat shall
state that the developer/owner and all subsequent owners grant the
City, or its designated representative, authority to enter onto its
property in the future to construct the deferred parking in the areas
shown on the approved site plan if owners fail to take action sixty
(60) days after receiving written notice by the City. The costs incurred
by the City shall be repaid by the owners or shall be placed as a
special lien against the property. Development and construction by
the City shall not be in lieu of a municipal zoning ordinance violation,
but shall be in addition to any action taken for violation of provisions
of this Section of the UDC.
I.
Modification Of Standards.
1.
In order to ensure that adequate, but not excessive, parking
is provided for a site, to promote environmental initiatives, and
to support alternative modes of transportation, flexibility in parking
through a modification to the requirements found herein may be requested.
2.
An applicant may request a modification of the requirements
of this Section of the UDC by providing a parking demand study, as
defined below, that supports the request and demonstrates by clear
and convincing evidence that the requested modifications are appropriate
for the site and do not cause detriment to adjacent properties.
b.
Elements Of A Parking Demand Study. The parking
demand study shall contain the following information as determined
by the City of Chesterfield:
(1)
The study shall be signed by a licensed professional
engineer or certified planner.
(2)
A plan which graphically depicts where the parking
spaces, loading spaces, stacking area, and parking structures are
to be located, as well as the on-site circulation for automobile,
pedestrian, and bicycle movement.
(3)
A report which demonstrates how any variations
from this Section were calculated and upon what assumptions such calculations
were based; and how everything shown on the plan complies with, or
varies from, applicable standards and procedures of the City.
(4)
The plan shall show all entrances and exits for
any structured parking and the relationship between parking lots or
structures and the circulation.
(5)
The plan, supported by the report, shall show the
use, number, location, and typical dimensions of parking for various
vehicle types, including passenger vehicles, trucks, vehicles for
mobility-impaired persons, motorcycles, buses, other transit vehicles
and bicycles.
(6)
The plan, supported by the report, shall include
phasing plans for the construction of parking facilities and any interim
facilities planned.
(7)
Whenever the applicant requests to reduce the number
of required parking spaces, or to exceed the maximum parking provided
for in this Section, the required report shall document how the proposed
parking was calculated and upon what assumptions such calculations
were based.
(8)
Such other information as determined by the Department
to be necessary to process the parking demand study.
c.
Design Features And Review Criteria. Design features
and review criteria, including, but not limited to, those listed below,
will be reviewed when in conjunction with requests for modification
to any of the requirements of this Section.
(1)
The parking demand study provides sufficient number
and types of spaces to serve the uses identified on the site.
(2)
Adequate provisions are made for the safety of
all parking facility users, including motorists, bicyclists and pedestrians.
(3)

phase of development of the district.
(6)
The development provides opportunities for shared
parking or for other reductions in trip generation through the adoption
of transportation demand management (TDM) techniques to reduce trip
generation, such as car pools, van pools, bicycles, employer transit
subsidies, compressed work hours, and high-occupancy vehicle (HOV)
parking preference.
(7)
Reductions in the number of parking spaces should
be related to significant factors such as, but not limited to:
(a)
Shared parking opportunities;
(b)
Hours of operation;
(c)
The availability and incorporation of transit services
and facilities;
(d)
Opportunities for reduced trip generation through
pedestrian circulation between mixed uses;
(e)
Off-site traffic mitigation measures;
(f)
Recognized variations in standards due to the scale
of the facilities;
(g)
Parking demand for a specified use; and
(h)
The provisions of accessible parking spaces beyond
those required per the UDC.
d.
Approval. Requests for modifications will be considered
by the Director of Planning and may be approved if the requested modifications
are appropriate to the site and do not cause detriment to the adjacent
properties. If said request for modifications is approved, the property
owner(s) involved in the parking demand study shall submit a written
agreement to the City of Chesterfield requiring that the parking facility
and any associated transportation demand management (TDM) techniques
shall be maintained without alteration unless such alteration is authorized
by the Director of Planning. Such written agreement shall be approved
by the City of Chesterfield and recorded by the property owner with
the St. Louis County Recorder's Office prior to the issuance of a
building permit, and a copy filed in the project review file.
(1)
Review procedure. Requests for a reduction in the
minimum parking requirement:
(a)
The Director of Planning shall review and may approve
requests for reduction for up to twenty percent (20%) of the minimum
parking requirement.

be subject to the review and approval of the Planning Commission.
(c)
Requests to exceed the maximum parking requirement
by twenty percent (20%) shall be subject to the review and approval
of the Director of Planning.
(d)
Requests to exceed
the maximum parking requirement by more than twenty percent (20%)
shall be subject to the review and approval of the Planning Commission.
Where Planning Commission approval is required for the proposed parking,
the applicant shall submit a statement that identifies measures to
mitigate for the increase in parking area. Mitigation measures shall
be subject to the review and approval of the Planning Commission and
may include, but not be limited to, the following:
(e)
Review of other modifications. Requests for modifications
to the requirements of this Section, other than those listed above,
shall be submitted to the Department for review and approval.
J.
Previously Approved Reductions. Developments with parking reductions
approved by the City of Chesterfield prior to the enactment of this
Section of this UDC shall be required to provide parking in accordance
with the minimum parking requirements at the time the reduction was
granted. Any property owner with a previously approved parking reduction
wishing to apply "minimum parking for retail centers" may do so in
lieu of utilizing the previously approved parking reduction. No property
shall be permitted to utilize a parking reduction and the parking
for retail centers option concurrently.
K.
Supplementary Off-Street Parking And Loading Requirements. In
addition to the above parking and loading requirements, the following
standards shall apply:
1.
In all zoning districts, all parking and loading areas, including
driveways, shall be paved, except in the FP, PS, NU, AG, LLR, E-1,
E-2 and R-1 Districts, where the City of Chesterfield may approve
an alternate dustproofing method.
2.
All areas for off-street parking and loading in the C-2, C-3,
C-4, and C-7 Districts shall be so arranged that vehicles at no time
shall be required to back into any street or roadway to gain access
thereto.
3.
For all non-residential uses, off-street parking and loading
shall be so designed such that a single unit vehicle shall not be
required to back into a vacant parking space or into a street or roadway
in order to turn around or exit.
4.
An area used for off-street parking spaces for five (5) or more
vehicles, when located in any PS Park and Scenic, NU Non-Urban, AG
Agricultural or residential district, shall not be closer to an adjoining
PS Park and Scenic, NU Non-Urban or residential district than ten
(10) feet. Said parking setbacks shall be effectively screened. Such
screening shall consist of a sightproof fence or wall, and such screening
shall be not less than five (5) feet in height above the surface elevation
of the parking area, except where sight distance regulations at street
intersections require other arrangements. When requested by the property
owner, the Department may approve the use of topographic features,
landscaping, or a combination of fences, walls, topographic features
or landscaping in lieu of fences or walls, where such alternates will
achieve a comparable effect. The limitations of this Subsection may
be modified in a development plan when authorized under a planned
district procedure.
5.
In a C Commercial or M Industrial District, no unenclosed parking
or loading space or internal drive, except for ingress and egress
drives, shall be closer to the street right-of-way than fifteen (15)
feet. The area within fifteen (15) feet of the street right-of-way
shall be landscaped as approved by the Department, and such landscaping
shall be adequately maintained. The limitations of this Subsection
may be modified in a development plan when authorized under a planned
district procedure.
6.
In a C Commercial or M Industrial District, no unenclosed parking
or loading space or internal drive shall be closer than ten (10) feet
to any adjoining PS Park and Scenic, AG Agricultural, NU Non-Urban
or residential district. Said parking setbacks shall be effectively
screened. Such screening shall consist of a sightproof fence or wall,
and such screening shall be not less than five (5) feet in height
above the surface elevation of the parking area, except where sight
distance regulations at streets require other arrangements. When requested
by the property owner, the Department may approve the use of topographic
features, landscaping, or a combination of fences, walls, topographic
features or landscaping in lieu of fences or walls, where such alternates
will achieve a comparable effect. Except for the screening provisions,
the limitations of this Subsection may be modified in a development
plan when authorized under a planned district procedure.
7.
Required off-street parking, stacking and loading spaces shall
not include spaces located in the floodplain or floodway, as determined
by the City of Chesterfield, except when accessory to a permitted
or conditional use in the FP Floodplain Overlay District.
8.
All parking spaces required by this UDC shall be located on
the same parcel of land as the use to be served except:
a.
Parking for one (1) or more uses in a commercial
or industrial district may be provided on a separate lot from the
use or uses to be served when said separate lot is within a similar
zoning district type and within three hundred (300) feet of the use
or uses to be served, as measured along a pedestrian pathway. When
two (2) or more uses combine to provide the required parking space
jointly, the parking space so provided shall equal the total space
required if each were to provide parking space separately. Joint or
remote parking areas provided in accordance with this Subsection shall
be comprised of a minimum of twenty (20) stalls except when provided
in conjunction with uses in the C-1 Neighborhood Business District.
Such parking must be approved by the Director of Planning. Subsequent
to approval, said parking plan and an appropriate legal instrument
of agreement among the owners of the various properties involved shall
be recorded with the County Recorder of Deeds, with a copy to be filed
with the City of Chesterfield. Such recorded plans and agreement shall
be binding upon the owners of the properties involved and their successors
and assigns and shall limit and control the use of land included in
the plan to those uses and conditions approved by an officer designated
by the City of Chesterfield and agreed to by the owners of the properties
involved.
9.
Off-street parking areas shall provide ingress and egress to
any public right-of-way only at such locations as approved by the
City of Chesterfield.
10.
No off-street parking space required under this UDC shall be
used for any other purpose. Where a change in use creates greater
parking requirements than the amount being provided, a municipal zoning
approval (MZA) shall not be issued unless provision is made for the
increased amount of required off-street parking.
11.
Where an addition is made to an existing use which does not
comply with the parking requirements cited for such use, additional
parking shall be provided in proportion to the addition.
13.
Tandem parking shall count as one (1) space.
[CC 1990 § 31-04-05; Ord. No. 2801 § 3 (Exh. A), 6-16-2014; Ord. No. 3060, 8-19-2019; Ord. No. 3152, 8-30-2021; Ord. No. 3192, 4-19-2022]
A.
Purpose.
1.
The purpose of the sign regulations provided herein are to encourage
excellence in design of signs, fostering economic viability of the
community, and provide safe and concise directional information designed
to facilitate traffic flow. Signs shall be designed so as to protect
motorists, bicyclists, and pedestrians from distractions that may
cause crashes or other detrimental impacts.
2.
Signs shall not overload the public's capacity to receive information,
or cause visual confusion by interfering with pedestrian or vehicular
traffic. Signs shall conform to the character of the community, enhance
the visual harmony of development, and preserve the public health,
convenience, welfare and/or safety within the City of Chesterfield
by maintaining the high aesthetic quality of the community.
3.
The City does not intend to infringe on the rights of free speech
as protected by the First Amendment to the United States Constitution
and Article I, Section 8, of the Missouri Constitution. All regulations
in this Article are to be construed, whenever possible, in favor of
vigorous political debate and accommodation of the rights of residents
and visitors to speak freely.
B.
Scope Of Provisions.
1.
These regulations are supplemented and qualified by the regulations
of the particular zoning district in which a sign may be located and
by additional general regulations appearing elsewhere in this UDC
which are incorporated as part of this Section by reference. This
Section contains regulations applicable to all signs in all zoning
districts.
2.
Regulations for any signs may be made more restrictive in the
conditions of the ordinance governing a particular Planned District
or Special Procedure. Regulations may also be modified when a sign
package is submitted and approved by the City of Chesterfield.
3.
On the effective date of this UDC, no sign, except a sign presently
so lighted, shall be illuminated by intermittent light sources. This
prohibition shall not apply to the manual changeable copy on a sign.
4.
When sign illumination is desired, it shall be arranged so as
to not cast light directly from any source of illumination on any
public right-of-way or on adjoining properties in the "NU" Non-Urban,
"PS" Park and Scenic, "AG" Agricultural or any residential district.
C.
Permits And Municipal Zoning Approvals (MZAs) For Signs.
1.
Unless excepted by these regulations or the City of Chesterfield
Building Code, no sign shall be erected, constructed, posted, altered,
enlarged, maintained, or relocated until an MZA has been issued by
the Department and a sign permit issued by St. Louis County Department
of Public Works. Before any MZA is issued, an application, provided
by the Department, shall be filed, together with drawings and specifications
as may be necessary to fully advise and acquaint the Department and
St. Louis County Department of Public Works with the location, construction,
materials, manner of illuminating, and securing or fastening, and
the wording or delineation to be carried on the sign. All signs that
are to be illuminated by one (1) or more sources of artificial light
shall require a separate electrical permit and inspection conducted
by St. Louis County Department of Public Works.
2.
Structural and safety features and electrical systems shall
be in accordance with the requirements of the City of Chesterfield
Building Code or any applicable building codes being enforced by the
City of Chesterfield. No sign shall be approved for use unless it
has been inspected by the Department issuing the permit and is found
to be in compliance with all the requirements of this UDC and applicable
technical codes. Signs found to be in violation of the requirements
of this UDC and/or applicable technical codes and which are determined
to be a danger to public health and safety may, after fifteen (15)
days of an inspection determining said violation and after notification
to the property owner, be dismantled and removed by the City of Chesterfield.
The expense for such action shall be charged to the owner of the property
on which the sign is erected and shall be filed as a special lien
thereon.
3.
Planning Commission Approval. The proponent of a sign subject
to Planning Commission approval as set out in subsequent Sections
shall file with the Department, in addition to those document requirements
specified in Section 405.05.050(C) of this Article, a written statement
addressing the following information:
a.
The underlying purpose of such a sign.
b.
Why such a sign should exceed the maximum height
and/or outline area specification for a particular sign in order to
accomplish the underlying purpose as stated in item 405.05.050(C)(3)(a)
above.
c.
What the proponent of such a sign believes the adverse
impact may be upon the underlying purpose of such a sign if the proponent
is compelled to reduce the height and/or outline area of such a sign
to within the maximum height and/or outline area specification for
any one (1) sign and the factual basis supporting such belief.
d.
The approximate distance the proposed sign will
be from other existing or planned structures visible or planned to
be visible within a radius of one thousand (1,000) feet from said
sign, identifying such structures with sufficient particularity to
enable the Planning Commission to determine whether there is a reasonable
likelihood of an adverse public health, convenience, welfare and/or
safety impact within the one thousand (1,000) foot radius area while
maintaining the high aesthetic quality of said area.
e.
What steps, if any, the proponent has taken to integrate
the design with the surrounding environment in order to minimize the
amount of visual clutter, and to avoid the distraction to pedestrians
and motorists beyond that necessary to convey the underlying purpose
of said sign.
f.
If no steps (referred in Section 405.05.050(C)(3)(e)
above) have been taken, provide information as to why such steps should
not be required of the Applicant.
g.
Any other information, such as length of frontage,
special speed limit or topographic considerations, that the proponent
deems pertinent to the approval of such a sign request.
D.
Sign Package Submittals.
1.
The purpose of a sign package is to provide comprehensive, complementary
and unified signage throughout a single planned zoning district, development
or contiguous lots under common ownership. If a sign package exists
for a multi-lot development or subdivision, then individual lots within
that subdivision or development may not submit their own, separate
sign package. In addition, developments of a certain size, quality,
or mix of uses may require special signage consideration. Therefore,
in order to encourage superior design, quality and character, comprehensive
sign packages allow for specialized review of signs and flexibility
from standard signage requirements.
2.
When a sign package is requested for a proposed or existing
development, the criteria for signs, as provided for in this Article,
may no longer be applicable in its entirety or portions thereof. The
reason for the requested modification is to provide for flexible sign
criteria that promotes superior design and is tailored to a specific
development which may vary from general ordinance provisions.
3.
Consideration of flexibility in sign criteria is based on a
number of review factors, including, but not limited to, the physical
impact of the proposed comprehensive sign package, the quality of
the proposed comprehensive sign package, and mitigation of unfavorable
conditions such as excessive signs, light spillover from signs, height,
and other related conditions and potentially negative impacts.
4.
When a sign package is requested for a development, the following
shall be submitted to the Department:
a.
A narrative detailing the reasoning for the sign
package request and why it will enhance the proposed development above
what would be permitted through the City of Chesterfield UDC.
b.
The maximum number of proposed signs.
c.
Location, size, height, construction material, and
placement of all proposed signs.
d.
General elevations of all proposed freestanding,
monument, wall, and any other sign that requires City of Chesterfield
approval.
e.
Illumination level, color and type. Illumination shall conform to the Section 405.04.030, Lighting standards, of this Article.
f.
Dimensions, height, square footage of all existing
signs or note that none exist for both freestanding and attached signs
(submit picture of all existing signage).

3.
Notwithstanding any other provisions of this UDC, no use may
be made of land or water within any zone established by this Section
in such a manner as to create electrical interference with navigational
signals or radio communication between the airport and aircraft, make
it difficult for pilots to distinguish between airport lights and
others, result in glare in the eyes of pilots using the airport, impair
visibility in the vicinity of the airport, create bird strike hazards,
or otherwise in any way endanger or interfere with the landing, takeoff,
or maneuvering of aircraft intending to use the airport.
4.
The regulations prescribed by this Section shall not be construed
to require the removal, lowering, or other change or alteration of
any object not conforming to the regulations as of the effective date
of this UDC, or otherwise interfere with the continuance of the non-conforming
use. Nothing contained herein shall require any change in the construction,
alteration, or intended use of any object, the construction or alteration
of which was begun prior to the effective date of this UDC, and is
diligently prosecuted. Notwithstanding the preceding provision of
this Subsection, the owner of any existing non-conforming structure
or tree is hereby required to permit the installation, operation,
and maintenance thereon of such markers and lights as shall be deemed
necessary by the Director of Planning to indicate to the operators
of aircraft in the vicinity of the airport the presence of such airport
obstruction. Such markers and lights shall be installed, operated,
and maintained at the expense of the airport to be protected thereby.
[CC 1990 § 31-04-07; Ord. No. 2801 § 3 (Exh. A), 6-16-2014]
A.
General.
1.
Purpose. The purpose of these regulations is to control the
division of land within the City of Chesterfield in order to promote
the public health, safety, and general welfare of the City by regulating
the division and redivision of land in order to lessen congestion
in the streets and highways; to further the orderly development and
appropriate use of land; to establish accurate records of land subdivisions;
to protect land title; to implement the general plan; to secure safety
from fire, and other dangers; to facilitate adequate and coordinated
provision for transportation, water, sewerage, schools, parks, playgrounds,
and other public requirements; to facilitate the further division
of larger tracts into smaller parcels of land; to preserve natural
features, such as stands of trees, streams, significant rock formations,
historical landmarks; and, in general, to facilitate the orderly coordinated,
efficient, and economic development of the City of Chesterfield.
2.
Administration. The Department may adopt, amend, and publish
rules and instructions within the intent of this UDC for the administration
of this UDC to the end that the public be informed and that approval
of plats be expedited.
3.
Parcels Of Land Created By Court Order. Any court ordered division
of a tract of land must comply with the requirements of this UDC.
B.
Large-Lot Subdivision. Where the proposed division of land constitutes
a large-lot subdivision, the following provisions shall apply:
1.
Lot Design Standards. The standards of Section 405.04.080(B), Single-Family Residential Lot Design Standards, of this Article, shall apply in addition to the following:
a.
Access for proposed lots may be provided by private
roadway easements which may be included as part of the gross area
of the lot. Lots with double frontage shall normally have driveway
access to the internal private roadway or local street. Any other
access shall be approved where justifiable topographic and other site
conditions are presented which prohibit access from the internal street.
b.
Building setbacks of the zoning district shall be
observed from designated private roadway easement lines and public
rights-of-way.
c.
Where there is a question as to the feasibility
of access to a desirable building site from the proposed roadway due
to factors such as creeks, steepness of terrain, or other adverse
natural physical conditions, the Department may withhold approval
until engineering studies are presented to the Department which establish
that the site is accessible.
d.
All lots containing three (3) acres or more shall
have a minimum width at the building line of two hundred (200) feet.
e.
Minimum frontage width shall be determined at the
building line, except that lots fronting on a circular turnaround
shall have a minimum width at the required building line of one hundred
(100) feet.
2.
Improvements.
a.
No improvement plans are required for large-lot
subdivisions, unless the streets therein are proposed by the developer
for dedication to the City of Chesterfield.
b.
Streets.
(1)
Private roadway easements shall have a minimum width of fifty (50) feet. Minimum pavement requirements set forth in Section 405.04.090(C) of this Article are not applicable to roadway easements for servicing large-lot subdivisions.
(2)
When a large-lot subdivision is proposed adjacent
to a street that is accepted and maintained by the City of Chesterfield,
or St. Louis County (arterial roads), right-of-way dedication may
be required as necessary for the relocation or widening for an adjoining
county or City road.
c.
Sidewalks shall not be required for a large-lot
subdivision.
d.
Water Supply. In the absence of a public water supply,
wells shall be constructed or a connection to a private water supply
system shall be provided so that an adequate supply of potable water
will be available to every lot in the subdivision. The standards for
same shall comply with the requirements of the Missouri Department
of Natural Resources.
e.
No stormwater drainage improvements shall be required
for a large-lot subdivision except where individual lot access is
requested to an existing public street or where necessary to control
erosion or damage to a street right-of-way to be dedicated to the
City of Chesterfield in which case the provisions of Section405.04.080(I),
Storm Sewers, of this Article, shall apply and land subdivision improvement
bonds or escrows shall be provided by the developer in accordance
with Article 02 of this UDC.
f.
Sanitary Sewers.
(1)
Where an approved publicly or privately owned sanitary
sewer is not located within two hundred (200) feet and reasonably
accessible, but where plans for installation of sanitary sewers in
the vicinity of the subdivision have been prepared and approved by
the Missouri Department of Natural Resources, the City of Chesterfield,
MSD, or private sewer district, within their limits, the developer
shall install sewers in conformity with such plans, although a connection
to an existing main may not be immediately practicable. In such cases,
and until a connection is made with an approved publicly or privately
owned sewer system, the use of a sewage treatment facility will be
permitted, provided that such disposal facilities are constructed
in accordance with the regulations and requirements of the Missouri
Department of Natural Resources and this UDC and constructed under
the observation and inspection of MSD or private sewer company, within
its limits, and the City of Chesterfield.
(2)
Where no sewers are accessible and no plans for
same have been prepared, the developer shall install sewer lines and
a disposal system in accordance with the requirements of the preceding
Subsection. In areas outside MSD boundaries, the developer may instead
install an individual sewage disposal system for each lot, but each
such individual sewage disposal system shall comply with the regulations
and requirements of the Missouri Department of Natural Resources and
be constructed under the observation and inspection of, and approved
by the City of Chesterfield.
g.
Reflectorized street signs shall not be required
for large-lot subdivisions other than at each intersection of a designated
private roadway easement with an existing or proposed publicly maintained
street. Such signs shall be placed within the public right-of-way
in accord with the standards of the City of Chesterfield.
h.
In a large-lot subdivision, a streetlight shall
be required only at each intersection of a private roadway easement
with an existing or proposed publicly maintained street.
i.
No landscape plan shall be required for a large-lot
subdivision.
j.
For large-lot subdivisions, monuments shall be required
at corners and angle points of the outboundary only. Individual lots
therein shall be identified by monuments at boundary corners, and
at other such locations selected by the developer. Public streets
within a large-lot subdivision shall contain monumentation to identify
the street right-of-way as required for subdivisions of lots of less
than three (3) acres.
3.
Private Agreements.
a.
A trust indenture shall be required for a large-lot
subdivision only in the event that common land or recreational facilities
are contained within the subdivision. However one may be utilized
for streetlights and roads.
b.
If no indenture is utilized, all large-lot subdivisions
shall have recorded, with or on the plat, a statement guaranteeing
road maintenance.
c.
Private restrictions proposed for the subdivision
shall be reviewed by the Department and City Attorney and shall be
referenced on the record plat.
[CC 1990 § 31-04-08; Ord. No. 2801 § 3 (Exh. A), 6-16-2014]
The size, shape, and orientation of lots and the orientation
of structures shall be designed to provide desirable building sites
logically related to topography, natural features, streets, parking
areas, common land (if any), other structures, and adjacent land uses.
Due regard shall be given to natural features, such as large trees,
unusual rock formations, watercourses, and sites which have historical
significance, scenic views, and similar assets, the preservation of
which would add attractiveness and value to the subdivision.
A.
Improvements.
1.
Plans for improvements shall be prepared by a registered professional
engineer; and the streets, storm sewers, sidewalks, pedestrianways
(unless waived by the Department or Commission), and sanitary sewers
shall be staked by a registered land surveyor.
2.
The owner of the tract may prepare and secure tentative approval
of a final subdivision plat of the entire tract, but the improvements
shall be either installed or guaranteed in the form of a land subdivision
bond, or an escrow agreement in a portion of the area for which a
record plat is approved for recording. However, all improvements required
by the City shall be complete and approved prior to issuance of more
than eighty-five percent (85%) of the building permits of all lots
in the subdivision plat.
3.
Utilities, including water mains, streets, storm and sanitary
sewers, and sewage treatment plants shall be designed and built or
guaranteed by escrow to serve the platted area or be designed and
built or guaranteed by escrow to serve the area to be initially developed
in such a manner that they can easily be expanded or extended, as
the case may be, to serve the entire drainage area or watershed.
4.
Required improvements for large-lot subdivisions are addressed in Section 405.04.070(B) of this Article.
5.
Acceptance And Final Approval. Before the developer's obligation
to the City of Chesterfield is terminated, all required improvements
shall be constructed under the observation and inspection of the inspecting
agency and accepted for maintenance or given final approval by the
City.
B.
Single-Family Residential Lot Design Standards. The design standards
set forth in this Section are the minimum design standards to be used
by the single-family residential subdivision. Unless otherwise set
forth below, the standards and procedures established elsewhere in
this Article as applicable to all subdivisions, shall apply to residential
subdivisions as well.

Exceptional Development Conditions. Where there is a question
as to the suitability of a lot or lots for their intended use due
to factors such as rock formation, soil conditions, steepness of terrain,
flood conditions, or other adverse natural physical conditions, the
Department may, after adequate investigation, withhold approval of
such lots until engineering studies are presented to the Department
which establish that the method proposed to meet any such condition
is adequate to avoid any danger to health, life, or lot improvement.
C.
Multiple-Family Residential Subdivision Design Standards. The
design standards as set forth in this Section are the minimum standards
for the multiple-family residential subdivision. Unless otherwise
set forth below, the standards and procedures established elsewhere
in this Article as applicable to all subdivisions shall apply to multiple-family
subdivisions as well.
1.
Lots.
a.
A multiple-family residential subdivision may consist
of only one (1) parcel of land or may include separate lots for one
(1) or more multifamily buildings or may include separate lots for
each dwelling unit.
b.
If divided into lots, such lots shall not be deemed
lots for the purpose of determining minimum lot area as provided in
Article 03 of this UDC; provided, however, that the total number of
dwelling units does not exceed the maximum density requirements of
the zoning district or of any special procedure ordinance enacted
pertaining to the tract.
2.
Street Frontage. Any such lots need not front or abut directly
on a street, provided that suitable access and easements are provided
for both vehicular and pedestrian traffic.
3.
Circular Turnaround; frontage. The minimum building line will
in no event be less than fifteen (15) feet from any road maintenance
and utility easement. However, this Article or any other Article of
this UDC may require a greater front yard or building line setback.
4.
Parking Areas.
a.
Parking bays on multiple-family access streets may
be accepted by the Department to satisfy off-street parking space
requirements in multiple-family subdivisions.
b.
Parking areas should be of sufficient dimension
to accommodate a nine-foot-by-nineteen-foot parking bay independent
of the driveway aisles. All internal parking lot aisles shall be not
less than twenty-two (22) feet in width.
5.
Yard Limitations. In the event the plan proposes the construction
of dwelling units either with walls joined together or having a common
wall but on separate lots, such group of dwelling units or walls,
or both shall be deemed one (1) structure for the purpose of determining
the side, front, and rear yard limitations of this UDC.
6.
Party Wall Cross Easement Agreements. If the proposed subdivision
necessitates the creation of party wall agreements, cross easements,
or other similar agreements to be of record for the use and benefit
of two (2) or more dwelling units, the developer shall submit to the
Department all such agreements or indentures at the time of submission
of the record plat for approval.
D.
Non-Residential Subdivision Design Standards. The design standards
as set forth in this Section are the minimum design standards to be
used by the non-residential subdivider. Unless otherwise set forth
below, the standards and procedures established elsewhere in this
Article as applicable to all subdivisions shall apply to non-residential
subdivisions as well.
1.
Lots.

a temporary turnaround as shown on any recorded subdivision plat unless
and until the temporary turnaround is actually constructed and has
been approved by the City of Chesterfield. In addition, no building
permit will be issued for display units on proposed lots that would
be located where temporary turnarounds are required. The Department
may grant a variance, provided that the following conditions are met:
(1)
The developer submits to the Department statements
from all prospective lot purchasers affected by the temporary turnaround,
excluding the developer himself/herself, declaring that they agree
to the use of their driveways for executing the turnaround movements
at the terminus of the street and acknowledging that any repairs made
necessary due to damage to the driveway caused by the use of their
driveway for the turnaround movement shall in no way be deemed the
responsibility of the City of Chesterfield; and
(2)
Provide an easement for the turnaround movement
approved by the City of Chesterfield.
m.
A subdivision plat involving new or existing streets
crossing railroad tracks shall provide adequate rights-of-way, including
approach rights-of-way and slope easements for construction of an
underpass or overpass, unless otherwise specified by the Planning
Commission. Approval of the Public Service Commission and the City

association] is responsible for all repairs and maintenance."
|
(2)
Installation of these signs shall be the responsibility
of the developer, and the cost for same shall be included in the escrow
established for subdivision improvements. The developer shall be responsible
for all maintenance and/or replacement of these signs until such time
as all of the trustees are residents of the subdivision, at which
time the trustees will be responsible for all maintenance and/or replacement
of these signs.
r.
Sleeves for future electric and water services shall
be installed to any non-paved area isolated by street pavement. The
sleeve shall extend one (1) foot beyond pavement and shall be marked
with a metal marking wire for future tracing.

Exception: In the R-1 Zoning District, where the minimum lot
frontage is one hundred twenty-five (125) feet, sidewalks may be omitted
on loop streets of not more than twenty-six (26) lots and on cul-de-sac
streets of not more than thirteen (13) lots. The right-of-way requirement
would then be thirty-four (34) feet, with additional easements as
required for drainage and utilities; however, a minimum building line
of forty (40) feet shall be maintained.
|
2
|
In any residential zoning district where eight (8) or fewer
single-family lots, including corner lots, are proposed on a cul-de-sac
street which will not contain sidewalks, a forty-foot right-of-way
is permitted with additional easements as required for drainage and
utilities.
|
3
|
Right-of-way and pavement widths indicated are minimum requirements.
Additional widths may be required based on traffic study as directed
by City of Chesterfield.
|
4
|
Minimum frontage is a function of lot size and is determined as explained in Section 405.04.080(B) of this Article.
|
5
|
Where no sidewalks are required, a forty-five-foot right-of-way
is permitted with additional easements as required for drainage and
utilities.
|
6
|
As an option, the right-of-way width may be reduced by ten (10)
feet with the placement of required sidewalks within a five-foot-wide
sidewalk, maintenance, utility and roadway widening easement. If said
option is chosen, the distance from the established right-of-way to
the building line shall be increased by five (5) feet.
|
7
|
Twenty-six-foot standard; twenty-foot standard if designed as
a loop or cul-de-sac street, provided that the cul-de-sac does not
serve more than thirteen (13) lots and loops limited to forty-five
(45) lots.

Collector streets in a non-residential subdivision may be built
in two (2) stages of two (2) lanes each stage.
4.
A minimum radius of thirty-two (32) feet at the back of the
curb or edge of pavement shall be required at all local street intersections
in a non-residential subdivision, except tracts developed in an M-1,
M-2, M-3, LI, or PI Industrial Zoning District, which shall require
a minimum radius of forty-five (45) feet at all street intersections.
Intersections of major and collector streets shall require intersection
geometries as directed by the City of Chesterfield.
5.
All curbs shall be six-inch minimum vertical curb with appropriate
wheelchair ramps where sidewalks are required.
6.
Culs-De-Sac.
a.

loading, unloading, and parking, which provisions are adequate for
the uses proposed within the subdivision.
8.
Right-Of-Way Dedication At Railroad Crossings. There shall be
no requirement for a non-residential subdivision to provide for rights-of-way,
including approach right-of-way and slope easements, for construction
of an underpass or overpass where a street in a non-residential subdivision
crosses railroad tracks, except in the case of major and collector
streets as defined elsewhere in this Article. Where at-grade crossings
of railroad tracks occur, the installation of electric warning signals
or other precautionary measures may be required if deemed by the Commission
to be necessary for the public safety. Approval of the Public Service
Commission and the City of Chesterfield is required for all railroad
crossings.

other than at each intersection of a designated private roadway easement
with an existing or proposed public street.
G.
Disclosure Of Responsibility For Street Maintenance.
1.
So long as there shall be a private street or a street not accepted
by the City of Chesterfield for maintenance within any subdivision,
no person shall sell, lease, rent, offer to sell, lease or rent, or
advertise for sale, lease or rental, any dwelling unit or non-residential
property without disclosing to each prospective purchaser or tenant
his/her responsibility with respect to subdivision streets in the
manner required by this Section. For the purpose of this Section,
"prospective purchaser or tenant" includes any person making inquiry
of any responsible party with respect to purchase, rental, or lease
of a dwelling unit or non-residential facility.
2.
Required Disclosure.
a.
Disclosure shall be made to each prospective purchaser
or tenant in substantially the following form, where applicable:
"The streets in this subdivision are private. The owners, homeowners'
association, or condominium association is responsible for all repairs
and maintenance."
|
or
|
"The construction design of these streets has been approved
by the City. Until such time as streets are accepted by the City for
maintenance, the owners, homeowners' association, or condominium association
will be responsible for all repairs and maintenance."
|
or
|
"The streets in this subdivision which are constructed below
the flood elevation are private. The owners are responsible for all
repairs and maintenance."
|
b.

[CC 1990 § 31-04-10; Ord. No. 2801 § 3 (Exh. A), 6-16-2014]
A.
Purpose. The purpose of the Chesterfield Driveway Access Location
and Design Standards is to recognize the City's desire to minimize
the number of permitted access points in an effort to improve traffic
flow, minimize congestion, and enhance the public safety. The number
of access points may be restricted, even to the extent that all other
criteria may be met.
B.
Scope Of Provisions. The Chesterfield Driveway Access Location
and Design Standards are supplemented and qualified by additional
general regulations as published by the Department and other appropriate
departments of the City and are incorporated as part of these design
standards by reference.
C.
General.
1.
The specifications and guidelines set forth in this Section
are to be applied to all roadways and properties that abut roadways
within the City, unless otherwise indicated.
2.
This Section shall be deemed to be supplemental to other Sections
regulating the use of public property, and in case of conflict, this
Article shall govern.
3.
Adequate sight distance to observe roadway traffic shall be
provided for a vehicle entering a roadway from a driveway.
4.
Upon the petitioner establishing unique and unusual circumstances
that make it difficult to apply these standards, the petitioner's
engineer, after establishing the unique and unusual circumstances,
may apply for a variance to the recommended dimensions set forth in
this Article if warranted by specific traffic conditions. The Department
may approve said deviation only upon the establishment that it is
in the public interest that same be approved.
5.
It shall be unlawful for any person to cut, break, or remove
any curb along a street, except as granted by the issuance of a special
use permit or the approval of improvement plans.
6.
It shall be unlawful for any person to construct, alter, or
extend, or permit or cause to be constructed, altered, or extended,
any driveway approach adjacent to a public street that can be used
as a parking space on the area between the curb and private property.
No parking behind the curb, within the public right-of-way, is permitted.
D.
Location Of Driveway Access.
1.
In making a determination as to the location of driveway access,
the Department shall consider:
a.
The characteristics of the proposed land use;
b.
The existing traffic flow conditions and the future
traffic demand anticipated on the development and the adjacent street
system;
c.
The location of the property;
d.
The size of the property;
e.
The orientation of structures on the site;
f.
The number of driveways needed to accommodate anticipated
traffic;
g.
The number and location of driveways on existing
adjacent and opposite properties;
h.
The location and carrying capacity of adjacent intersections;
i.
Proper geometric design of driveways;
j.
The spacing between opposite and adjacent driveways;
k.
Internal circulation between driveways;
l.
The speed of traffic on the adjacent roadway;
m.
Pedestrians, sidewalks, cyclists, and other modes
of transportation; and
n.
Surrounding terrain and vegetation, relative to
sight distance.
2.
Non-residential developments shall not be permitted driveway
access that requires backing maneuvers in a public street right-of-way
for parking or loading areas.
3.
A single-family housing unit's driveway access shall not be
restricted relative to backing maneuvers; however, whenever possible,
driveway access to arterial and collector streets for a single-family
housing unit shall utilize turnouts or a circular type driveway.
4.
One (1) curb cut shall be allowed for access to single-family
residential lots. More than one (1) curb cut may be allowed upon approval
by the City Engineer.
5.
For corner tracts, access to residential lots shall be provided
from the lesser (lowest classification) street. The determination
as to the lesser (or greater) street shall be made by the City Engineer
and based on the functional street classification and traffic.
6.
Driveway access to gated developments shall be as approved by
the City Engineer. At a minimum, a stacking distance of sixty (60)
feet shall be provided, and a turnaround for rejected vehicles, designed
to accommodate a single unit truck, must be provided in advance of
the gate.
7.
No cuts through a left-turn reservoir of a median shall be permitted
in order to provide for left-turn movements to driveway approaches.
8.
Driveways in right-turn-lane transition areas shall be as approved
by the Department.
9.
When a commercial, industrial or multifamily development abuts
more than one (1) public street, access to each abutting street may
be allowed only if the following criteria are met:
a.
It is demonstrated that such access is required
to adequately serve driveway volumes and will not be detrimental or
unsafe to traffic operations on public streets. The Department may
require the submittal of a traffic study, which demonstrates that
such access is required.
b.
The minimum requirements, as set forth in Figure
A2, for corner clearance for commercial or multifamily driveways are
met.
c.
The proposed access does not promote cut-through
traffic.
d.
It is demonstrated that such access is required
to adequately provide access for emergency responders.
E.
Spacing Of Driveway Access.
1.
Application of the Chesterfield Driveway Access Location and
Design Standards requires identification of the functional classification
of the street on which access is requested and then application of
the appropriate spacing requirements.
2.
The functional classification of streets in the City is identified
on street maps maintained by the Department. The functional classification
of any street in the City not indicated as an arterial or collector
street on this plan shall be determined using the functional street
classification defined by the American Association of State Highway
and Transportation Officials (AASHTO) Green Book, A Policy on Geometric
Design of Highways and Streets.
3.
Driveway access spacing shall be measured from the center line
of the proposed driveway pavement to the nearest edge of the roadway
pavement (paved shoulder or back of curb) of the adjacent or opposite
driveway or street as indicated in Figure A1. The driveway spacing
requirements shall not apply to single-family lots accessing local
streets.
4.
Opposite right driveways shall be located no closer than the
minimum requirements of Table A1.

|
The driveway spacing requirements shall not apply to single-family
lots accessing local streets.
|
5.
Additional opposite right spacing over and above that set forth
in Table A1 may be required if it is determined by the Department
that there is insufficient left-turn storage or weave maneuver area
between the opposite right and proposed driveway. This determination
shall be made under peak traffic conditions.
6.
A minimum of one hundred (100) feet shall be required for opposite
left drives for all street classifications where no center-line medians
are constructed.
7.
If the center line of an opposite drive is less than fifteen
(15) feet from the center line of the proposed drive, the drives form
an intersection and the minimum spacing requirements shall apply for
the closest adjacent drive.
8.
Adjacent drives shall be located no closer than the minimum
requirements of Table A2.
9.
When necessary, and to maximize spacing and limit access points,
the Department may require shared access.

|
F.
Corner Clearance. Corner clearance for driveway access shall
meet or exceed the minimum driveway spacing requirements for that
roadway. When minimum spacing requirements cannot be met due to lack
of frontage and all means to acquire shared access drives or cross
access easements have been exhausted, the following requirements shall
apply:
1.
At intersections of arterials with channelized right-turn lanes
with yield control, a corner clearance distance in accordance with
those set forth in Figure A2 shall be required for the first downstream
driveway. This distance shall be measured from the channelized median
to the nearest edge of the proposed driveway as indicated in Figure
A2.
2.
No driveway approach on a corner lot may be located closer than
thirty (30) feet to local streets, seventy-five (75) feet to collector
streets, one hundred (100) feet to minor arterials and one hundred
twenty (120) feet to major arterials. This measurement shall be taken
from the intersection of the prolongated property lines at the corner,
as shown on Figure A2. Where applicable, easement lines shall be substituted
for property lines. When these requirements cannot be met due to lack
of frontage, the driveway may be located such that the radius or flare
will begin at the farthest property line.
G.
Shared Or Cross Access.
1.
A joint private access easement may be required between adjacent
lots fronting on arterial and collector streets in order to minimize
the total number of access points along those streets and to facilitate
traffic flow between lots. The location and dimensions of said easement
shall be determined by the City Engineer.
2.
Private cross access easements may be required across any lot
fronting on an arterial or collector street in order to minimize the
number of access points and facilitate access between and across individual
lots. The location and dimension of said easement shall be determined
by the City Engineer.
H.
Maximum Number Of Non-Residential Entrances. The number of non-residential
entrances for each property or site shall be restricted on the basis
of traffic requirements as determined by the City Engineer. The maximum
number allowed, if all traffic requirements are satisfied, shall be
as indicated in Table A3.

I.
Geometric Design Of Driveway Access.
1.
Any driveway approach located within the public right-of-way
shall meet the City's standards.
2.
Edges of curb openings for driveways shall be a minimum of five
(5) feet clear distance from the nearest edge of street stormwater
inlets and ten (10) feet clear distance from street corner radius
point.
3.
In the case of corner lots, no parts of a driveway shall be
constructed within the sight distance triangle area bounded by the
property lines of a corner lot and a line connecting two (2) points
on the property lines, each measured thirty (30) feet from the intersection
of the two (2) property lines at the intersection.
4.
The maximum width of residential driveway approaches measured
at the property line shall not exceed twenty-six (26) feet in width,
while the minimum width shall not be less than ten (10) feet.
5.
The maximum width of commercial, industrial and multifamily
driveway approaches for two-way operation shall not exceed forty (40)
feet except that the City Engineer may issue permits for driveway
approaches greater than forty (40) feet in width on major streets
to handle special traffic conditions. The minimum width of commercial
and multifamily driveway approach for two-way operation shall not
be less than twenty-four (24) feet.
6.
The combination of the width of two (2) driveways for residential circular drives shall not exceed thirty-two (32) feet, if two (2) curb cuts are approved per Section 405.04.100(D)(4) of this Article.
7.
The angle of driveway approach shall be between seventy degrees
(70°) and ninety degrees (90°) for one-way drives.
8.
A minimum driveway throat length of forty-five (45) feet for
non-residential local streets and collector streets, sixty (60) feet
and eighty (80) feet for arterials, as shown in Figure A5 shall be
required to allow free flow for traffic entering the site in order
to avoid traffic into the development causing delays to the through
traffic stream. A minimum driveway throat length of one hundred twenty-five
(125) feet shall be required on signalized driveways, or longer as
may be recommended by a traffic study; and a minimum driveway throat
length of two hundred fifty (250) feet shall be required for commercial
retail centers that have over two hundred thousand (200,000) gross
feet of leasable floor area. The "driveway throat length" shall be
defined as the distance from the street to the first point of conflict
in the driveway.
9.
For the benefit of traffic safety and flow on collector and
arterial streets, tapered or channelized deceleration lanes for vehicles
turning right into high-volume or intersection-type driveways may
be required if warranted. Design of right-turn deceleration lanes
shall be in accordance with the AASHTO Green Book on auxiliary lanes.
The spacing requirements for driveways not meeting the specifications
in Tables A1 and A2 may be lessened or waived if tapered or channelized
deceleration lanes are used.
10.
Access points on arterial and collector streets may be required
to be signalized in order to provide safe and efficient traffic flow.
A development may be responsible for all or part of any right-of-way,
design, hardware, and construction costs of a traffic signal if it
is determined that the signal is necessitated by the traffic generated
from the development.
J.
Street Structures. No driveway shall interfere with public facilities
such as streetlight or traffic signal poles, signs, fire hydrants,
crosswalks, bus loading zones, utility poles, fire alarm supports,
drainage structures, or other necessary street structures. The City
Engineer is authorized to order and effect the removal or reconstruction
of any driveway constructed prior to the adoption of these standards
which is found to be a non-conforming structure and when the driveway
needs to be reconstructed or relocated due to the evident public need.
("Public need" includes, but is not limited to, changes required for:
public safety, traffic flow, pedestrian concerns, maintenance requirements,
changes in street structure in the area, flood control and/or street
drainage, etc.). The cost of reconstructing or relocating such driveways
shall be at the expense of those creating the reconstruction or relocation
need and/or those receiving the benefit.
K.
Permits.
1.
Any plans submitted for building approval which include or involve
driveways shall be referred to the City Engineer for review and/or
approval under one (1) of the two (2) following procedures before
a building permit is issued:
a.
New property development under improvement plans.
Approval of driveway location and design for new properties and/or
developments included in the property's improvement plan shall be
considered the permit for driveway installation as submitted.
b.
Special use permits. Any property owner desiring
a new and different driveway or an improvement to an existing driveway
at an existing residential or non-residential property shall make
application for a special use permit, in writing, on such forms as
are provided by the City, and designating the contractor who will
do the work, to the City Engineer. The application shall be accompanied
by a sketch or drawing clearly showing the driveway, parking area,
or driveway to be connected and the measured location of the nearest
existing driveways on the same or opposite sides of the roadway. The
City Engineer will prescribe the construction procedure to be followed.
2.
Special use permits are not required when an existing residential
driveway is simply being removed or replaced in kind. (NOTE: Special
use permits are required for any significant structure change, land
use change, or property boundary change to any specific identifiable
parcel of land.)
3.
All permits granted for the use of public property under the
terms of this Section shall be revocable upon a due cause showing
of public need.
L.
Penalties.
1.
Any persons, firm, association, entity, or corporation violating
any provisions of this Article, or any employee, assistant, agent,
or any other person participating or taking part in, joining or aiding
in the violation of any provisions of this Article shall be guilty
of an ordinance violation punishable by fine of not less than five
dollars ($5.00) and not more than five hundred dollars ($500.00) for
each and every day that such violation continues at the discretion
of the court. Each day will be considered a separate violation.
2.
In addition to the penalties hereinabove authorized and established,
the City may issue stop-work orders and the City Attorney shall take

E.
Surety.
1.
Performance Guarantee.
a.
Prior to the issuance of a grading permit, the applicant
shall deposit a surety with the City as described below and as required
for particular sites. Said grading permit shall be issued upon the
approval of the Department and the applicant depositing with the City
a sum equal to that which would be required to guarantee the performance,
restoration, maintenance and/or rehabilitation of said site based
upon the approved grading plans and the approved SWPPP. In the case
of owners, contractors or builders who have previously violated the
subject and provisions of this Section, the amount of the surety shall
be increased in each case based on such previous experience.
b.
If at any time the Department determines that the surety deposited with the City is in an amount that is not sufficient to guarantee the performance, restoration, maintenance and/or rehabilitation of the site based upon the approved grading plans and the approved SWPPP, the permittee shall deposit additional surety with the City in an amount determined by the Department within fifteen (15) days after receiving notification from the Department. If the permittee does not deposit the additional surety with the City, the Department may issue a stop-work order as outlined in Section 405.02.120(H) of this UDC.
c.
The surety shall be released as detailed in the
Manual.
d.
Any portion of the deposit not expended or retained
by the City hereunder shall be refunded when the grading operation
is completed and the soil and drainage conditions are stabilized to
the satisfaction of the City.
e.
The Director of Planning or the Director of Public
Works may perform, or have performed, any work necessary to restore,
maintain and/or rehabilitate the site based upon the approved grading
plan, approved SWPPP, and/or the requirements of this Article. All
costs incurred in the performance of this work shall be charged against
the surety the applicant deposited for the grading permit. By applying
for a grading permit, the applicant consents to the City or its contractor
entering the property and holds them harmless regarding any work that
they perform.
f.
Deposits required by this Section shall be in conjunction
with a deposit agreement and may be in the form of cash or letters
of credit as follows:
(1)
Cash deposits shall be required when the estimate
developed by the Department for the performance guarantee as set out
herein is less than ten thousand dollars ($10,000.00) and in all other
cases where the owners, contractors, or builders shall wish to make
cash deposits, the same shall be deposited with the Director of Finance
to be held in an interest-bearing account dedicated for that purpose,
with all interest accruing to the City to offset administrative and
other costs of maintaining the cash deposits;
(2)
An irrevocable letter of credit drawn on a local
financial institution acceptable to and in a form approved by the
City Attorney and the Director of Planning. The instrument may not
be drawn on a financial institution with whom the developer or a related
entity has any ownership interest or with whom there is any joint
financial connection that creates any actual or potential lack of
independence between the institution and the developer. The letter
of credit shall be drawn on a local banking institution within the
greater Metropolitan St. Louis area and within the State of Missouri.
The letter of credit shall provide that the issuing institution will
pay on demand to the City such amounts as the City may require to
fulfill the obligations herein and may be reduced from time to time
by a writing of the Director. The letter of credit shall be irrevocable
for at least two (2) years and shall state that any balance remaining
at the expiration, if not renewed, shall automatically be deposited
in cash with the Director of Finance, unless a new letter of credit
is issued and agreed to by the City or the City issues to the institution
a written release of the obligations for which the letter of credit
was deposited. The developer shall pay a non-refundable fee of two
hundred dollars ($200.00) to the City with submission of a letter
of credit and one hundred dollars ($100.00) for any amendment or extension
thereof, to partially reimburse the City's administrative and review
costs in accepting and maintaining such letter of credit.
(3)
Certificates of deposit, treasury bills, or other
readily negotiable instruments, the type of which has been approved
by the Director of Finance, endorsed to the City, the cash value of
which shall be in an amount not less than the amount specified by
the Department in its estimate of the cost for grading, restoration,
maintenance, and/or rehabilitation of said site based upon the approved
grading plans.
2.
Downstream Impoundment Protection And Restoration Guarantee.
a.
If, in the opinion of the Department, lakes, ponds,
detention areas or other impoundment areas may be impacted by proposed
work, the permittee shall perform pre-construction and post-construction
surveys of each facility and post a bond, in a form acceptable to
the City, as guarantee that the permittee will perform work in such
a manner as to protect downstream facilities and will restore any
damage or negative impact his/her development had on the facilities.

to any clearing, grading, demolition or other construction related
to the proposed development and prior to plan approval.
c.
An acceptable bond shall be submitted prior to plan
approval.
d.
Post-construction surveys shall be performed within
twelve (12) months of the completion of the proposed development or
two (2) years from the start of the development, whichever is greater.
e.
Within three (3) months of the post-construction
survey, the developer shall restore affected impoundment areas to
the condition they would have been in if his/her development had not
occurred.
f.
If the owner/operator of potentially impacted facilities
will not grant the developer the necessary easements to complete the
surveys or restoration work, the requirements of this Subsection are
null and void.
F.
Inspections.
1.
The applicant shall provide a qualified inspector to conduct
regular inspections of the proposed development site. The qualifications
of the inspector and frequency of inspection shall be as detailed
in the Manual.
2.
By applying for a grading permit, the applicant consents to

progress. The applicant shall notify the City upon commencement and
completion of the following: clearing, rough grading, finish grading
before stabilization; and all reestablishment and construction work.
Said notice shall be made as detailed in the permit issued to the
applicant.
G.
Use Of Streets During Grading Operations.
1.
Notice. At least five (5) working days prior to the use of any
street in the City by trucks or hauling or grading equipment engaged
in grading activities in the City which requires the use of the streets
maintained by the City, the contractor in charge may be required to
submit a written report to the Department, specifying the kind and
description of trucks or hauling or grading equipment, and the loaded,
and unloaded weight of trucks and hauling equipment, and the number
of each and the length of time they will be required to use the streets
of this City. The contractor shall furnish the Department with all
other information required of him/her to estimate or determine the
amount of wear and tear, or damage, if any, that may be caused to
streets by such usage. The applicant shall also provide the Department
visual documentation, such as a video, and/or photographs, of the
existing condition of the streets to be used. Before construction
actually commences or while the work on the streets is in progress,
the Department may require the applicant to post a pavement restoration
bond, in such sum as is directed by the Department, with the City
to guarantee the City compensation for any damage to streets, curbs,
sidewalks or public facilities.
2.
Routes. The Department shall, at least two (2) working days
before the commencement of work and usage of the streets of the City,
notify the contractor of the route or routes to be used by such trucks
and equipment. The permittee and contractor shall be charged with
the duty of seeing that the trucks or equipment use only the route
or routes approved by the Department. In the event of any emergency
requiring a change in route or routes, or if the Director of Public
Works finds or determines that any route or routes so designated are
not safe or that excessive damage is being caused to any street or
streets in the City by such usage, or if he/she finds the welfare
of the City so requires, he/she may, upon one (1) days' notice to
the permittee and contractor, order that the trucks or equipment use
only the alternate route or routes so designated by the Director of
Public Works.
3.
Inspection. The Director of Public Works shall cause a thorough
inspection to be made of the condition of the pavement of the streets
designated and used under the permit, as well as the curbs and sidewalks,
and shall make written reports of his/her findings, including with
his/her report after termination of the work, his/her estimate of
the cost of restoring the street, curbs and/or sidewalks to their
original condition.
H.
Damage To Streets, Etc. At the time the Department approves
the route or routes to be used as provided in this Section, the applicant
shall be notified that the City will hold the applicant liable for
unusual wear and tear or damage to the streets, curbs, and sidewalks
resulting from such usage, and that acceptance of the route or routes
by the applicant shall constitute an agreement on his/her part to
pay the reasonable cost of restoring the streets, curbs and sidewalks
in question to their original condition. Within thirty (30) days after
notification, the applicant shall cause the streets, sidewalks and
curbs to be restored to their original condition. Failure to effect
the repairs shall be cause for action against the surety.
I.
Construction Dirt, Debris, Waste.
1.
BMPs At Construction Site. After excavation or construction
is commenced on any lot or tract of land in the City, and until sodding,
planting, concreting, paving or other final surfacing is in place
which will avoid washing or spreading of dirt and mud onto other property,
sidewalks, curbs, gutters, streets and the space between sidewalks
and curbs, the permittee, the owner of the property, contractor or
developer in charge of work shall construct and maintain temporary
siltation control devices or other approved measures to prevent such
washing or spreading of mud or dirt. As may be required throughout
the day, during the course of excavating or construction, dirt and
mud on the sidewalks, curbs, gutters and streets, and the space between
sidewalk and street resulting from work must be removed.
2.
Removing Mud From Vehicle Wheels. The permittee, owners, contractors,
and developers, jointly and severally, shall provide their personnel
with shovels, a wash-down station, or other equipment as necessary
to remove dirt from the wheels of all vehicles leaving any clearing
or grading site where mud has accumulated on the wheels, before such
vehicles enter any public or private street of the City. It shall
be unlawful for the permittee, or any owner, contractor, developer
to permit any vehicle to leave such place with mud on the wheels which
is liable to be dispersed over any public or private street of the
City, and it shall be unlawful for any driver of a vehicle to enter
upon the public or private streets of the City without having removed
or had mud removed from the wheels prior to such entry. Each occurrence
shall be a separate offense.
3.
Spilling Materials On Streets. The permittee, owners, contractors,
and developers, jointly and severally, who may load dirt, mud or other
materials on any vehicle at any grading site in the City, during construction
or otherwise, shall so load the same that no portion thereof shall
be spilled or be liable to be spilled on the streets of the City in
violation of this provision, and it shall be unlawful for any driver
to operate a vehicle on the streets of the City which is loaded in
such manner that it spills or is liable to spill mud, dirt, or other
materials on the streets.
4.
Boards Over Sidewalks. Boards, tracks, or other protection must
be laid over sidewalks, curbs and gutters to avoid dirt and mud accumulating
therein, as completely as possible and to prevent breakage or damage
to such installations of whatever material constructed. Damage to
walks, curbs and gutters will be repaired by the permittee, owner,
contractor, or developer, or the Director of Public Works may, upon
ten (10) days' notice, cause to have them repaired at the permittee's,
owner's, contractor's or developer's expense.
5.
Waste Material. During the course of construction, excavation,
or grading, the permittee, owners, contractors, and developers are
required to collect and dispose of all paper, refuse, sticks, lumber
and other building waste, and all other waste material, and to prevent
the same from blowing or otherwise being scattered over adjacent public
or private property. Any waste material that is blown or scattered
over the site, as well as on any adjacent public or private property,
shall be picked up daily, and disposed of properly. Washout from concrete
trucks must be controlled in a manner so as not to adversely impact
the site, adjacent public or private property, or adjacent streams
and storm sewer systems.
6.
Sanitary Facilities. Adequate provisions must be made for sufficient
temporary sanitary facilities to serve the number of workers on the
site.
7.
Planting Ground. All disturbed areas shall be sodded, planted,
concreted, paved or otherwise surfaced within five (5) calendar days
after completion of each phase of work to avoid washing or spreading
of dirt and mud onto other property, sidewalks, curbs, gutters, streets
and the space between sidewalks and curbs. If determined by the City
that an undue hardship exists because of unfavorable ground conditions,
the City may grant an extension of time by which the disturbed areas
have to be surfaced.

Levee District. Prior to approval of grading and improvement plans
on any parcel in Chesterfield Valley on which jurisdictional wetlands
have been identified, the developer/property owner shall reimburse
a pro rata share of the cost of development of the mitigation area.
M.
Natural Watercourse Protection.
1.
No clearing, grading, excavation, construction or disturbance of any kind is permitted within fifty (50) feet of the top of bank of Bonhomme Creek, Caulks Creek or Creve Coeur Creek, or within twenty-five (25) feet of the top of bank of all other natural watercourses depicted on the most current United States Geological Survey (USGS) 7.5 Minute Series (Topographic) Maps for the City of Chesterfield, Missouri (buffer areas). Permanent vegetation and existing ground elevations and grades within the above-mentioned buffer areas shall be left intact and undisturbed except as permitted in Section 405.04.110(M)(2) of this Article. If no top of bank is apparent, the ten-year, twenty-four-hour or fifteen-year, twenty-minute water surface elevation will determine the top of bank. The top of bank and the buffer area shall be depicted on the grading plan.
2.
The following structures, practices and activities are permitted
in the buffer areas:
a.
Roads, bridges, trails and utilities approved by
the Director of Public Works are permitted within the buffer areas,

A.
General.
1.
The purpose of this Section is to provide standards and regulations
governing land development in order to reduce or prevent flooding
and at the same time minimize damage to real property.
2.
During the construction phase of development, facilities shall
be provided to prevent erosion and siltation in accordance with the
City's Sediment and Erosion Control Manual.
3.
The City of Chesterfield hereby adopts by reference The Metropolitan
St. Louis Sewer District (MSD) Rules and Regulations and Engineering
Design Requirements for Sanitary Sewer and Stormwater Drainage Facilities,
February 1, 2018. The City of Chesterfield, unless otherwise acted
upon, shall adopt by reference any changes made by MSD to the standards
effective as of February 1, 2018.
4.
Ability To Waive Requirements. The Director of Public Works
is empowered to grant exceptions to the stormwater standards on a
case-by-case basis when specific requirements are onerous and inappropriate
for a particular development.
5.
In addition to the standards as promulgated by MSD, the City
of Chesterfield hereby supplements those standards which will be added
to and effective in the City of Chesterfield as of the new MSD standards
and shall read as follows:
a.
General.
(1)
Compacted granular backfill is required within trenches located
in the right-of-way and adjacent areas. (This includes sidewalks that
are installed on easements adjacent to the right-of-way.)
(2)
Siltation control measures are to be designed, constructed and
maintained until adequate vegetation is established to prevent erosion.
(3)
The adequacy of any existing downstream storm sewer system is
to be verified and upgraded, if necessary.
b.
Design Criteria.
(1)
Pavement under drains are to be installed the full width of
the pavement at all curb inlets.
c.
Detention.
(1)
When developments are within sites served by local and regional
detention facilities, the City may require an analysis of downstream
effects and compliance with detention requirements at time of development
for areas served by regional-type detention basins which were installed
previously.
d.
Stormwater in Chesterfield Valley.
(1)
Stormwater in Chesterfield Valley is subject to review and approval
by the City of Chesterfield for compliance with the Chesterfield Valley
Master Stormwater Plan.
(2)
The Director of Public Works shall maintain a copy of the Chesterfield
Valley Master Stormwater Plan in his/her office and make it available
at all times hereafter.
(3)
Stormwater in Chesterfield Valley is subject to review and approval
by MSD and the Monarch Chesterfield Levee District in accordance with
the Intergovernmental Cooperation Agreement between MSD and MCLD.
(4)
Construction of required stormwater improvements per the Chesterfield
Valley Master Stormwater Plan shall occur with development and developers
shall coordinate with the owners of the properties affected by construction
of the required improvements. In the event that the ultimate required
improvements cannot be constructed concurrently with a development,
the developer shall provide interim drainage facilities and establish
sufficient escrows as guarantee of future construction of the required
improvements, including removal of interim facilities. Interim facilities
shall be sized to handle runoff from the 100-year, 24-hour storm event
as produced by the Master Stormwater Plan model. The interim facilities
shall provide positive drainage and may include a temporary pump station,
if necessary, to achieve positive drainage. Interim facilities shall
be removed promptly after the permanent stormwater improvements are
constructed.
(5)
Alternate geometry, size and/or type of stormwater improvements
that are functionally equivalent to the required improvements per
the Chesterfield Valley Master Stormwater Plan may be proposed. Functional
equivalence is said to be achieved when, as determined by the Director
of Public Works, the alternate proposal provides the same hydraulic
function, connectivity, and system-wide benefits without adversely
affecting any of the following: water surface profiles at any location
outside the development; future capital expenditures; maintenance
obligations; equipment needs; frequency of maintenance; and probability
of malfunction. The City will consider, but is not obligated to accept,
alternate plans. If the Director of Public Works determines that a
proposed alternative may be functionally equivalent to the Chesterfield
Valley Master Stormwater Plan improvements, hydraulic routing calculations
will be performed to make a final determination of functional equivalence.
The Director will consider proposals for alternate improvements, but
is not obligated to have the hydraulic analysis performed if any of
the other criteria regarding functional equivalence will not be met.
The hydraulic routing calculations regarding functional equivalence
may be performed by a consultant retained by the City of Chesterfield.
All costs related to consideration of an alternate proposal, which
shall include any costs related to work performed by the City's consultant,
shall be reimbursed to the City.
(6)
All necessary Chesterfield Valley stormwater easements shall
be provided to accommodate future construction of the Chesterfield
Valley Master Stormwater Plan improvements, and any and all Chesterfield
Valley Master Stormwater Plan improvements shall be depicted on the
site development plan(s) and improvement plans.

the responsibility of the property owner unless the improvement is
accepted by another agency for maintenance.
(8)
All Chesterfield Valley Master Stormwater Plan improvements,
as applicable, shall be operational prior to the paving of any driveways
or parking areas unless otherwise approved.
(9)
As-built plans for Chesterfield Valley Master Stormwater Plan
improvements shall be submitted to the City and the Monarch Chesterfield
Levee District for review and approval.

Regulations For Satellite Dishes.
a.
The purpose of the following regulations for satellite
dishes or dish antennas of greater than three (3) feet in diameter
is to improve the aesthetic appearance of these structures within
all zoning districts. The regulations shall not impose unreasonable
limitations on, or prevent reception of satellite delivery signals
by receive-only antennas or impose costs on the users of such antennas
that are excessive in light of the purchase and installation cost
of the equipment. Satellite dishes three (3) feet or less in diameter
are exempted from the regulations contained herein.
b.
In all zoning districts, one (1) satellite dish
shall be permitted on any lot or parcel of land. Any additional satellite
dishes proposed for a lot require a conditional use permit. A satellite
dish may be ground-mounted or roof-mounted; however, only a ground-mounted
dish is permitted in the single-family residential districts. No satellite
dish shall be mounted as an appurtenance to a chimney, tower, tree,
spire, or pool deck.
c.
In no case shall a satellite dish be permitted to
be attached to a portable device. Any satellite dish must be stationary.
The location of a satellite dish shall be as approved by the Department
on the site plan or plot plan of the property. All satellite dishes
require a building permit.
d.
No message or identification, other than the manufacturer's
identification, shall be allowed to be portrayed on a dish antenna.
The message or identification shall not exceed twenty-five one hundredths
(0.25) square foot in area. Satellite dishes shall be limited to mesh
construction; however, a satellite dish eight and one-half (8 1/2)
feet or less in diameter may be either of mesh or solid construction.
All dishes shall be finished in a single, neutral, non-reflective
color and surface which shall blend with the natural surroundings.
e.
Any ground-mounted satellite dish shall be located
in the rear yard, provided that on a corner lot, the dish cannot be
located any closer to the side street than the principal building
located on the lot. On any lot other than a corner lot, the dish shall
be placed in an area bounded by the side yard setback lines, the rear
wall line of the primary structure, and the rear yard setback line.
The side and rear setback lines shall be in accordance with the setback
requirements of the underlying zoning district.
f.
Ground-mounted satellite dishes in the commercial,
industrial, or multifamily districts shall be located in a designated
service area outside of any required landscape area, or front and
side yard setback area. The antenna shall not be placed in the area
between the front setback line and the structure.
g.
Screening of satellite dishes shall serve to reduce
the visual impact on adjoining properties without impeding the line
of sight of dish reception. The location and type of screening shall
be as approved by the Department on the site or plot plan.
h.
Screening shall be accomplished through the use
of fencing, landscaping, in the form of evergreen and deciduous trees
and shrubbery, structures or topography. For ground-mounted satellite
dishes in the single-family residential districts, trees and shrubs
shall be at least one-half (1/2) the height of the dish at the time
of planting. (The center of the dish shall be determined as the point
where the dish is attached to its base when viewed from off of the
site.) The landscaping material shall be maintained and replaced,
if it dies.
i.
Screening of roof-mounted antenna in commercial,
industrial or multifamily districts is required up to three (3) feet,
or to the center of the dish, whichever is greater. The design and
material composition of the screening shall be compatible with the
existing building design and colors and be approved by the Department.
j.
For buildings listed on the National or State Register
of Historic Places or the Chesterfield Register, the antenna shall
not be visible from fronting or flanking streets. This is to maintain
the aesthetic characteristics of the historic structures.
k.
For the residential zoning districts, other than
those permitting multifamily land use, the height of ground-mounted
satellite dishes shall not exceed twelve (12) feet above the average
grade. The dishes shall not exceed a diameter of ten (10) feet. For
lots of three (3) acres or more in the NU Non-Urban District, satellite
dishes shall not exceed a diameter of twelve (12) feet, with no restriction
on height; otherwise, dishes on lots less than three (3) acres in
the NU District shall not exceed twelve (12) feet in height or ten
(10) feet in diameter. Roof-mounted satellite dishes in the multifamily

retaining walls (closest edge to closest edge) shall be four (4) feet.
19.
Traffic Studies, Private Developments.
a.
Upon application for new development, proposals
to develop previously zoned but undeveloped property and/or the amendment
to an existing zoning, if a traffic study shall be determined necessary
by the Director of Planning, he/she shall notify the developer in
writing and the developer shall deposit with the City in a special
escrow the sum of two thousand dollars ($2,000.00) to be used as a
deposit toward the expenses incurred by the City in employing a traffic
consultant to study the traffic issues for the proposed development.
This may include review of traffic studies presented by the developer
or to undertake traffic studies on behalf of the City.
b.
Said traffic study shall collect data as determined
by the City or the City's traffic consultant to include, but not be
limited to, traffic counts, measurements of traffic gaps, sight distances
along adjoining streets, accident data, locations of nearby driveways,
etc. That information shall be collected so that the City may evaluate
those issues that are expected to arise as a result of said developments,
which would include, but are not limited to:
(1)
The amount of traffic the development could be
expected to generate at peak hours and for daily traffic.
(2)
The ability of the adjoining street systems to
accommodate the added traffic.
(3)
The need for additional street improvements (turning
lanes, improved traffic controls, etc.)
(4)
The effect of development on nearby properties,
adjacent driveways, etc.
(5)
The specific requirements of the study shall be
determined by the Department.
(6)
Current and projected levels of service.
(7)
Distance from the development considered.
(8)
Connection to stub streets.
c.
Upon receipt of a request to zone a new development
or upon submittal of a site development plan for previously zoned
but undeveloped property and/or a petition to amend an existing zoning
and upon the City's determination for the need of a traffic study,
the City shall forward a copy of the site plan along with any other
information concerning the development proposal to its traffic consultant.
The traffic consultant shall provide a specific proposal for services
detailing the action that he/she would undertake regarding the specific
traffic issue presented. After the City has reviewed the proposal
and deemed it fair and reasonable, a copy shall be provided to the
developer who shall have an opportunity to respond to the proposal
and offer his/her input as to proposed actions of the consultant.
Upon receipt of the City's authorization, the consultant shall proceed
with the work and present the findings to the City. The developer
shall provide full payment for said services of the City traffic consultant.
Failure of the developer to pay said funds into the special escrow
account shall be a cause for the petition to be held and not to proceed
until said payment has been paid.
d.
Upon the City's receipt of the report from its traffic
consultant, the developer shall be provided an opportunity to respond
to the report and present information to rebut, by substantial and
convincing evidence, facts to allow for mitigation of the study recommendation
of findings.
20.
Telecommunication Services. Sleeves for future telecommunication
services shall be installed adjacent and/or parallel to any proposed
roadway, or other locations as directed by the City of Chesterfield,
in order to facilitate the installation of utilities and telecommunication
