[Ord. No. 06-05-01 §701, 5-9-2006]
This Article establishes the design and construction standards
for public improvements installed in accordance with the provisions
of this Chapter.
[Ord. No. 06-05-01 §702, 5-9-2006]
A.
Engineering
drawing standards are as follows:
1.
All engineering drawings shall be of uniform size twenty-four (24)
by thirty-six (36) inches. Consultants shall have their own title
block. The registration seal of the responsible engineer shall be
placed in a convenient place on each sheet of plans.
2.
Whenever possible, engineering plans and profiles shall be drawn
to a standard scale of one (1) inch equals fifty (50) feet horizontal
and one (1) inch equals five (5) feet vertical. Drainage area maps,
construction details and cross section or contour maps shall be drawn
to a suitable scale.
3.
Elevations on profiles and sections or as indicated on plans shall
be City datum or U.S.G.S. datum. At least two (2) permanent bench
marks in the vicinity of each project shall be noted on the first
drawing of each project and their location and elevation shall be
clearly defined.
4.
The top of each plan shall be either north or east and a north arrow
should be used. The stationing on street plans and profiles may be
either from the left to right or from right to left, but on drainage
plans the stationing shall always begin at the low point.
5.
When more than one (1) drawing is involved in one (1) project, an
overlap of not less than one hundred (100) feet should be provided.
Each project shall show at least fifty (50) feet of topography on
each side. All existing topography and any proposed changes, including
utilities, telephone installations and so forth shall be shown on
the plans and profile.
6.
Revisions to drawings shall be indicated above the title block and
shall show the nature of the revision and the date made.
7.
Plans shall make consistent use of standard symbols throughout the
plan set. The cover sheet shall include a legend of all symbols used.
Symbols shall not duplicate and shall be clear on their indication.
Topography for which symbols are not standardized shall be indicated
and named on plans and profiles. In utilizing the standard symbols
for engineering plans, all existing utilities, telephone installations,
storm sewers, pavements, curbs, inlets and culverts and so forth shall
be shown with a broken line; proposed facilities with a solid line;
land, lot and property lines to be shown with a slightly lighter solid
line. Easements shall be shown and, if known, the book and page number
of the recording.
8.
The requirements outlined in these standards are only minimum requirements.
When unusual subsoil or drainage conditions are suspected an investigation
should be made and a special design prepared in line with good engineering
practice.
9.
Each plan should indicate the owner or subdivider for whom improvements
are to be constructed.
10.
Lot lines and dimensions shall be shown where applicable.
[Ord. No. 06-05-01 §703, 5-9-2006]
Five (5) sets of the engineering construction plans for public
works improvements shall be submitted to the City. After approval
by the City Engineer, one (1) set of the engineering plans will be
retained by the contractor on the job site.
[Ord. No. 06-05-01 §704, 5-9-2006]
Prior to the start of construction or installation of any infrastructure
improvements required pursuant to this Chapter, a pre-construction
conference shall be held with the developer, the contractor(s) responsible
for installation of the infrastructure improvement, a representative
from the Greene County Public Water Supply District No. 5, City Inspector,
Mayor and the City Engineer. The developer shall be responsible for
contacting the City Clerk to schedule the pre-construction conference.
The conference shall be held to ensure that all applicable provisions
of this Chapter or other applicable rule or regulation have or will
be met, that permits have been obtained and that questions regarding
the installation of improvements are resolved.
[Ord. No. 06-05-01 §705, 5-9-2006]
A.
Periodic
inspections shall be required during construction work. These inspection
requirements are outlined in the individual standards for streets,
sidewalks, drainage or other public improvements.
B.
The
developer shall provide inspection services for all public works improvements
that will be dedicated to the City of Fair Grove. These inspections
shall be performed by or under the direct supervision of the developer's
engineer who shall be registered in the State of Missouri. Inspections
shall be of sufficient frequency to enable the developer's engineer
to provide to the City of Fair Grove a sealed certification that the
improvements were constructed in accordance with the approved engineering
design plans or in accordance with approved as-built plans. Verification
may be made by the City Engineer and all fees charged back to developer.
C.
The
developer shall also submit copies of field inspection reports and
testing results in sufficient detail to record the history of the
entire installation, testing and deviations from the approved engineering
design plans. These reports shall bear the seal of an engineer registered
in the State of Missouri. The developer shall submit to the City copies
of all reports that are required to be submitted to the Missouri Department
of Natural Resources.
D.
These
inspections, reports and certifications shall be the financial responsibility
of the developer. In no case shall the presence of City personnel
during any part of the construction and testing constitute acceptance
by the City of Fair Grove or a substitute for on-site observation
by the developer's engineer.
E.
Unless
otherwise specified in any of the regulations contained in this Chapter,
the developer shall notify the City a minimum of twenty-four (24)
hours prior to any testing of public improvements. If the City requests
to be present during any phase of construction and testing and is
not notified by the developer, the developer shall uncover concealed
work or retest any materials or systems for the City's personnel to
observe.
F.
The
developer shall deliver three (3) sets of as-built plans to the City.
These plans shall include all public works improvements that will
be dedicated to the City and all stormwater facilities improvements.
The developer shall also submit these drawings in an electronic format
acceptable to the City.
[Ord. No. 06-05-01 §706, 5-9-2006]
A.
A minimum
of (1) temporary construction entrance is required at each site. Additional
temporary entrances may be provided if approved by the City.
B.
Only
construction entrances designated on the sediment and erosion control
plan may be used. The location of each construction entrance shall
be shown on the plan. Barricades shall be maintained if necessary
to prevent access at other points until construction is complete.
C.
Construction
entrances shall be constructed of one and one-half (1½) inches
crushed limestone meeting the following specifications:
1.
Minimum thickness of crushed limestone surface shall be six (6) inches.
Additional two (2) inch lifts of crushed limestone shall be added
at the discretion of the City if the surface of the initial construction
drive deteriorates or becomes too muddy to be effective.
2.
Construction entrances shall be a minimum of twenty five (25) feet
wide and fifty (50) feet long.
3.
In locations where an existing drive or street extends at least fifty
(50) feet into the site, the existing drive or street may be designated
as the construction entrance and construction of a new gravel entrance
is not required, unless job conditions warrant as determined by the
City.
[Ord. No. 06-05-01 §707, 5-9-2006]
A.
Detailed Specifications. All streets, curb and gutter and
sidewalks shall be constructed in conformance with the Greene County
Design Standards for Public Road Improvements, adopted June 23, 1980,
and last amended in April 1, 2002.
B.
Right-Of-Way And Pavement Widths. Right-of-way and pavement widths for roads shall be provided in accordance with the provisions of Article VI, Section 410.400(D).
