FINAL PLAT
PROPOSAL SUMMARY
At this time, the applicant is requesting final plat approval to create 16 lots and associated right-
of-way for Springfield 7th Addition. This phase represents the final phase of the development.
PARKS & RECREATION
The applicant dedicated portions of approximately 5.3 acres to the city for park land. This land is
for Bandimere Heights Community Park. Of this land, the city acquired approximately 2.7 acres
at a price of $24,600 per acre (the "purchase price"). Prior to final plat approval for any future
phase, the developer is required to repay to the city a pro rata portion of the purchase price plus
accrued interest from the date, April 10, 1998, the city purchased the approximately 2.7 acres to
the date of repayment by the developer plus interest at a rate of 8 percent per annum. The pro
rata portion of the purchase price shall be based on the proportion of the number of lots that are
included in the phase to the total number of lots remaining on the preliminary plat after platting
Springfield 1 st _ 3rd Additions. The pro rata share for Springfield 7th Addition is twenty-four (24)
percent of the purchase price plus accrued interest.
LANDSCAPING
The applicant has prepared a master landscape plan for the project. This plan has incorporated
tree preservation requirements as well as buffer yard requirements. The plan for the 7th Addition
contains a total of 30 overstory deciduous trees, 16 ornamentals, and 7 conifers. The city shall
require security as part of the final plat for the installation of the buffer yard plantings along
Lyman Boulevard and the rear yard plantings in the amount of $10,000.00.
STORMWATER MANAGEMENT
The proposed single family residential development of 6.2 developable acres is responsible for a.
water quality connection charge of $4,956.48 and a water quantity fee of $12,267.29. The water
Springfield 7th Addition Final Plat
August 23, 1999
Page 3
quality fee has been waived since the applicant is meeting NURP design for on site runoff. The
water quantity fees of $12,267.29 are payable to the city prior to the city filing the final plat.
GRADING
The site has already been graded with the previous phases of Springfield Addition. There are
earth berms and landscaping located along Lyman Boulevard to provide screening per the PUD.
The homeowners association will maintain the berm/landscaping. In conjunction with the utility
installation, minor grading will occur to restore the site to original grade.
UTILITIES
Municipal utility service has been extended to the site from the previous phases. The plans
propose on extending utilities through the site. This phase will also eventually service the
existing homestead/parcel to the east (Prewitts). Staff has received detailed construction plans
and specifications for both utility and street improvements. Upon review of the plans and
specifications, staff finds them to be in general conformance with City standards. The
construction plans and specifications and development contract approval also are being
considered for approval with the final plat. Copies of the construction plans are available for
review in the Engineering Department.
DRAINAGE
Stormwater runoff generated from the site will be conveyed via storm sewer and draintile
systems to existing stormwater quality ponds in the Springfield development for pretreatment
prior to discharging into Lake Riley. A drain tile system is proposed to address sump pump
discharge from the proposed dwellings. In addition, the drain tile will address subsurface
drainage in the street to help improve the life of the street.
STREETS
Detailed street construction plans and specifications have been submitted for staff review and
City Council approval. Staff finds the construction plans in general conformance with City
standards. Currently, Summerfield Drive terminates in a temporary cul-de-sac just west of
Greenview Drive. The temporary cul-de-sac will be removed and Summerfield Drive extended.
Summerfield Drive will again end in a temporary cul-de-sac end east of Greenview Drive.
Eventually this street will be extended through the parcel to the east and will connect
Summerfield Drive to Springfield Drive in the 1 st phase. A condition will be Placed in the
Development Contract/PUD Agreement indicating that Summerfield Drive will be extended in
the future. Staff believes the temporary cul-de-sac diameter/configuration should be expanded in
size to accommodate emergency vehicles, garbage trucks, delivery vehicles, etc. A temporary
Springfield 7th Addition Final Plat
August 23, 1999
Page 4
easement will be required over Lot 8, Block 1, to achieve this. The temporary easement will
expire upon the street extension through the Prewitts parcel.
A 5-foot wide concrete sidewalk will be extended along the south side of Summerfield Drive
consistent with the previous phases. Decorative residential street lights (3) will be installed as
well.
