[Ord. No. 11-2I 118 §1, 5-12-2016]
A. All plans for public improvements within the City of Farmington must
be approved by the Public Works Director prior to beginning construction.
This approval is a conceptual approval only and does not give detail
approval to any particular design item or data shown on the plans,
nor does it give approval for any deviation from City specifications
unless that deviation is shown on the plans by a general note. The
Engineer who sealed the plans is responsible for all lines and grades,
field data, constructibility of the design, and all other items affecting
the project including compliance with the City specifications.
B. All design requirements will be strictly adhered to unless written
justification for a design variance is presented to and approved by
the public works director prior to preliminary plat approval.
C. Should a request for a design variance occur after preliminary plat
approval and this causes non-conformance with the preliminary plat,
the Planning and Zoning Commission and City Council will have to approve
the amendment to the preliminary plat, as the authority to accomplish
this does not rest with the Public Works Director.
D. No streets, alleys, water mains, sanitary sewers, storm sewers, or
other public improvements will be accepted or approved by either the
City Council or Director of Public Works, unless the improvements
were constructed in accordance with Plans, Special Provisions, and
Technical Specifications approved by the Director of Public Works.
E. The following criteria have been established for the uniform treatment
of the location or relocation of utility facilities within the right-of-way
of the public street system in order to preserve the traffic-carrying
capacity of the street and to minimize interference with normal maintenance
operations. These requirements apply to all public and private utilities
including power transmission, telephone, cable television, telecommunications,
water, gas, oil petroleum products, pipelines, and any other utility
facilities (excluding sanitary sewers). The requirements apply to
underground, surface, or overhead facilities located within or crossing
street right-of-way. Exceptions to the requirements set forth will
be considered when major utility extensions are proposed or when improvements
by their size necessitate special consideration. All utilities installing
any facilities in a public right-of-way must meet the requirements
of the Department of Public Works and shall receive advance approval
from Public Works prior to commencing construction on a public right-of-way.
In order to receive approval, an engineering drawing detailing the
installation shall be required. This engineering drawing shall depict
adequate data to determine location and impact on other facilities
located in the public right-of-way. In the case of reconstruction
or rehabilitation where existing utilities will not be relocated and
where break repairs or normal maintenance are needed, the requirement
for an engineering drawing shall be waived.
1.
New subdivisions — residential. Parallel
installation of underground facilities, including meters, valves,
and other appurtenances within the street right-of-way are to be located
within a ten (10) foot area adjacent to the right-of-way line where
no sidewalks exist. In no case will the City allow the facility to
be constructed within the street pavement area except for valves necessary
for tapping existing facilities, nor will it be allowed to conflict
with the street drainage. Careful consideration must be given to the
location of valves, meter boxes, and other appurtenances, so that
interference with the sidewalk and street curb is minimized. Minimum
cover shall be forty-two (42) inches for water mains and thirty-six
(36) inches for all other underground facilities.
2.
New subdivisions — non-residential. Parallel
overhead and underground facilities are to be located within ten (10)
feet of the right-of-way line. Street lights and poles used to support
transverse crossings of the right-of-way shall not be located closer
than two (2) feet of the curb or edge of roadway or paved shoulder.
Poles, guys, anchors, braces, and other appurtenances for overhead
facilities shall not encroach into sidewalks or streets. Parallel
installation of the underground facilities, including meters, valves,
and other appurtenances, within the street right-of-way, are to be
located within ten (10) feet of the right-of-way line. In no case
will the City allow the facility to be constructed within the street
pavement area except for valves necessary for tapping existing facilities,
nor will it be allowed to conflict with the street drainage. Careful
consideration must be given to the location of valves, meter boxes,
and other appurtenances, so that interference with the sidewalk and
curb is minimized. Minimum cover shall be thirty-six (36) inches or
conforming to Federal, State, or local agency requirements, whichever
is greater.
3.
Existing subdivisions. Plans developed for
new underground or overhead facilities must be designed to take into
account existing utilities, as well as possible future utilities.
Where possible, corridors outlined in Paragraph (1) and Paragraph
(2) of this Subsection are to be adhered to. Due to existing facilities,
this may be impractical. Design based upon remaining within corridor
is encouraged, but it is understood local, State, and Federal codes
may make this impossible. Since existing conditions must be taken
into account, deviation from the corridor requirements in Paragraph
(1) and Paragraph (2) of this Subsection may be accepted.
F. Permits.
1.
All utility work to be performed within the right-of-way limits
of City-owned streets and alleys will require an excavation permit
from the Public Works Department prior to the work being done by the
utility or the utility's contractor. In emergency situations where
necessary repairs to an existing utility facility must be made immediately
in order to protect the public health, safety, and welfare, a permit
must be obtained as soon as possible after emergency repairs have
commenced.
2.
All utility work to be performed on State-maintained facilities
will require a permit from the Missouri Highways and Transportation
Commission. All requirements of the State must be met.
G. All excavation and cutting of City streets shall be done in conformance with Chapter
510, Article
II of the Municipal Code.
H. If a utility is found in a storm sewer structure during the course
of that structure's rehabilitation or reconstruction, the utility
would have to be relocated outside of the structure. Further, any
new utility will be prohibited from passing through any storm sewer
structure regardless of the age of the structure, and regardless of
whether there are existing utilities in the structure. Relocation
expense will be responsibility of the utility owner.
