3. Discussion Farmington Middle School Preliminary Plat
The land area included within this plat totals slightly more than sixty -four
(64) acres. The land has been previously divided along a line that has
been proposed as the alignment of a future east /west collector street with
a right of way of 100 feet. The entire 100 feet will be dedicated from
land purchased by the School. The City Engineer recommends a design speed
of 50 miles per hour for collector streets. Because this collector eventually
will cross the railroad right of way, and it will serve as an extension
of County Road 66 west of Highway 3, an "S" curve is necessary. In order
for the plat to serve the needs of the Middle School site plan, additional
property to the north will be required in the triangular are between the
existing site and the westerly end of the "S" curve. The Superintendent
of Schools has indicated that this additional property will be secured from
the current landowner. The site plan submitted with the plat shows five
entrances onto 208th Street. One objective of collector streets is to keep
access spacing to 1/8 of a mile or 660 feet. The School District has agreed
to eliminate two of the entrances and the City staff has agreed to accept
entrances closer than 660 feet based upon the amount of frontage that will
be controlled by the School District.
Because of its location, the plat is a focal point for utility extension
north and west of downtown. Service areas beyond this plat have been determined
for purposes of pipe sizing and function. The memo dated May 8, 1991 from
City Engineer Kaldunski identifies facilities as either trunk lines or laterals.
In general, lateral pipes are the responsibility of the developer, whereas
trunks become City responsibility at least to the extent of the oversizing
that is required. In certain instances, trunk lines do provide a lateral
benefit to the project. The City water system will be provided significantly
more flexibility as a result of this project. The Water Board contemplates
a north /south trunk along the west side of the railroad. A similar trunk
will be located within the right of way of 208th Street. The School plans
a loop around the building, and the City Engineer has requested water mains
on the property both to the south and east property lines within specific
easements. The City sanitary sewer trunk will extend northward from the
MWCC trunk sewer immediately east of the Pine Street turn around and terminate
on the north side of the Pine Street turn around and terminate on the north
side of 208th Street. This will then be ready to provide service to all
property east of County Road 31 within the existing boundaries of Farmington.
All storm drainage is directed to the on site ponding area or marsh east
of County Road 31. It is recommended that regrading shall be limited to
the land area above the 901 contour. Catch basins are recommended at two
locations along 208th Street and will be linked with the north /south storm
sewer west of the school and flow to the Vermillion River. This line will
also carry excess flow from the marsh. A storm sewer line will be required
along the north edge of the plat. It will empty into an open ditch bordering
the west side of the railroad.
As indicated, the storm water management pond on site shall be left undisturbed.
This means that the construction limits will need to be redrawn to exclude
areas below the 901° contour. One exception to this is the extension into
the ballfield area between the football and softball field, a low lying
area which can be filled more than is shown on the grading plan. The City
Engineer has indicated that fill material will be available from the road
construction project which might be useful in the development of athletic
fields. The grading plan also shows significant cuts and fills within the
flood plain. This earthwork will need to be approved by the Department
of Natural Resources. Silt fencing is required around the entire construction
site to control erosion.
Because the construction season is short, there is limited time during the
year when road construction can take place. The schedule of the School
District indicates that the school will be going up at the same time. This
is likely to produce conflict between projects unless an alternate route
is selected for school construction activity while the street is being built.
The staff has recommended that a temporary road should be constructed through
the park over the trunk sanitary sewer line. The base provided by sewer
line construction will provide a suitable location for a pedestrian connection
between the school and the central area of Farmington.
The City Engineer has indicated that there is a requirement for street trees
on this plat. A forty foot (40') spacing of two inch (2 caliper trees
is necessary along both sides of 208th Street. The types of trees encouraged
are: oak, hard maple, hackberry, Greenspire and Redmond Linden, Summit
and Marshall's Ash, ginkgo (male only) and Kentucky Coffee Tree. Up to
four species could be used along this right of way in clusters similar to
those identified on the landscape plan for the site. An enlarged landscape
plan will be required showing the shrubbery plantings to be placed adjoining
the building and parking areas.
Because of the time schedule of this development, all of the comments from
reviewing agencies have not been returned. In addition, the School District
has agreed to noted changes in the site layout that do not show up on the
plans submitted. Revised drawings and additional comments will be presented
at the Planning Commission meeting. In addition, there has been considerable
discussion on City fees related to this project. It would be helpful for
the staff to receive the architect's calculations of these fees now to prevent
any later misunderstanding during the development process.
Recommendation
Prepare a recommendation for approval of the preliminary and final plat
subject to the requirements identified in the City Engineer's memo of May 8th
and whatever comments are introduced during the meeting and forward them
to the City Council for the public hearing scheduled on June 3, 1991.
