Final Plat Review of Harvieux Addition
Land Use Review File No. 05-09
Upon review of the plans submitted by Demars-Gabriel Land Surveyors, Inc.
dated September 12,2005, I offer the following comments and recommendations:
GRADING, DRAINAGE & EROSION CONTROL
The existing site is heavily wooded with tree cover over approximately 80% of
the area with an existing house. The plans propose to grade about 9% to create
two new house pads and a proposed private driveway access off of Horseshoe
Curve for Lot 1 and off Pleasant View Drive for Lot 2. The proposed grading
will prepare the site for full walk-out house pads. Drainage swales have been
proposed along the sides of the houses to maintain the neighborhood drainage
pattern through the property.
The existing site drainage is encompassed within two different drainage areas.
The site drains off site to the southeast and southwest directions toward Lotus
Lake. The applicant is utilizing the existing grade contour and is not proposing
any storm sewer system. Overall, staff is fine with the proposed grading but has
some concerns on the grades along the east side of the parcel that may affect the
existing house on the east side of the parcel; as such, staff would recommend
installing gutters on the house on Lot 2 and discharge stormwater to the southwest
comer.
The plan proposes retaining walls for the driveway access on Lots 1 and 2. The
applicant should be aware that any retaining wall over 4' in height must be
designed by a structural engineer registered in the State of Minnesota. Also, it
will require a building permit from the Building Department.
Tree preservation fencing must be installed at the limits of tree removal. All
disturbed areas, as a result of construction, shall be seeded and mulched or sodded
immediately after grading to minimize erosion. A 75-foot minimum rock
construction entrance must be added to the entrance that will be accessed during
construction. If importing or exporting material for development of the site is
necessary, the applicant will be required to supply the City with a detailed haul
route and traffic control plan.
The City 01 Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

UTILITIES
No public utility improvements are proposed. The applicant is proposing to
extend the water and sanitary sewer services from the City's sewer and watermain
off Pleasant View Road for Lot 2 and off Horseshoe Curve for Lot 1. The
developer must submit a security to ensure that the street cuts are properly
restored to City standards.
According to the City's Finance Department records, the parcel was previously
assessed for one sanitary sewer and water hookup. However, the sanitary sewer
and water hookup charges will still be applicable for each of the new lots. The
2005 trunk hookup charge is $1,458 for sanitary sewer and $2,955 for watermain.
Sanitary sewer and watermain hookup fees may be specially assessed against the
parcel at the time of building permit issuance. All of these charges are based on
the number of SAC units assigned by the Met Council.
STREETS
The plan does not show any public street improvement. The plan proposes
accessing the lots via a private driveway access from the northeast corner of the
parcel off Pleasant View Road and Horseshoe Curve. Staff recommends
relocating the Lot 2 driveway access to the south along Lot 1 's north property line
to create more separation from the northern parcel's existing access.
RECOMMENDED CONDITIONS OF APPROVAL
1. Relocate Lot 1 sanitary sewer and water services from the northwest off J/
Pleasant View Road to the west off Horseshoe Curve.
2. Permits from the appropriate regulatory agencies will have to be obtained
including but not limited to the MPCA and the Watershed District.
