SUB J: Countryside Final Plat Approval - Lundgren Bros. Construction
BACKGROUND AND EXECUTIVE SUMMARY
On June 17, 2003, the City Council gave preliminary plat approval to the
Countryside Subdivision subject to conditions of approval. The applicant is
requesting final plat approval for 10 single-family lots and 2 outlots. Outlot A will
be platted in the future when the road Mill Creek Lane is extended and Outlot B will
be used as a storm water pond.
The final plat requires a simple majority of the city Council for approval.

STREETS
The proposed subdivision will have access via Kings Road. The road will have a 60-foot right-
of-way and will be constructed along the entire subject site frontage. Four of the lots will have
access via Kings Road and the remaining lots will have access via an internal Mill Creek Lane.
This street will be built as a temporary cul-de-sac. This cul-de- sac will extend in the future to
serve the Kortgard property. Based on the configuration of the subject property, another lot will
access the extension of the temporary cul-de-sac. The extension of Kings Road will enable the
six lots in the Oaks of Minnewashta (Outlot B) to be final platted. This project will have to
provide utility service extension to the Oaks of Minnewashta.
A sidewalk around the perimeter of the site (Kings Road) will provide access to the city park.
Part of the sidewalk is in the fight-of-way of the City of Victoria.
GRADING/DRAINAGE/EROSION CONTROL
There are two wetlands on the site. An exemption on the wetland in the western portion was
given on July 30, 2003. The only jurisdictional wetland that remains on site (subject to city
regulations) is the wetland adjacent to Lake St. Joe.
UTILITIES
Sewer and water will be available to the site with the extension of utilities. These utilities will be
stubbed to the 6 lots on the north side of Kings Road (Oaks of Minnewashta, Outlot B, which
still needs to receive final plat approval).
Storm water quantity and quality fees are required in the amount of $14,603.57. Each newly
created lot will be subject to City sanitary sewer and water hook-up charges at the time of
building permit issuance. The 2004 trunk utility hook-up charges are $1,458 per unit for sanitary
sewer and $2,814 per unit for water (hook-up charges are based on the number of SAC units
assigned by the Met Council).
PARK AND TRAILS
The site is located near Roundhouse Park, which is a large neighborhood park serving the west
Lake Minnewashta area. The 10 new homes will have access to the park by the new sidewalk.
The applicant will be required to pay a one-time park dedication fee of $28,000 with the final
plat.
