LANDSCAPING/TREE PRESERVATION
1 ndsca in plan has been submitted for acres Drive. A mix of Ash and Lon
A streetscape/ a p g p g
Maple trees will be planted along the boulevard following site grading. The necessary financial
guarantees will be required as part of the development contract.
No tree preservation easements will be required for The Woods at Longacres 2nd Addition. Tree
removal limits will be established at the time of building permit application for each lot.
Removal limits will be set at a distance of twenty (20) feet around the proposed building pad as
shown on the Grading and Drainage plan, provided that trees may be removed within approved
grading limits and for placement of utilities.
A number of significant trees are located within the Electric Transmission Line Easement in
Block 2. Removal or trimming of these trees may become necessary in the future: to avoid
interference with the power lines. Other significant trees and canopy cover exist along the
wetland boundaries. Variances were granted to move the house pads and grading limits away
from these vegetated areas. No vegetation removal shall be allowed in the wetland buffer areas.
Because a significant portion of canopy coverage is located in non - buildable areas, staff is not
requesting tree conservation easements. As stated above, tree removal limits will be identified at
the time of building permit approval
WETLANDS
Portions of two natural wetlands and one ag /urban wetland are located within The Woods at
Longacres 2nd Addition. Part of the wetland will be filled as a result of site grading for Lots 4
and 5, Block 3. The applicant has completed the wetland mitigation for this filling with the
previous phase. The proposed building pads are setback an appropriate distance from the
wetlands. Reduced front yard setbacks should allow the grading limits to be shifted away from
the wetlands providing for the preservation of the existing vegetation and natural buffer. All
wetland lots will have a buffer strip and will be posted with buffer monumentation signs.

GRADING AND DRAINAGE
Staff has reviewed the construction development plans for this phase. There have been some
minor revisions that staff has worked with the applicant's engineer on in an effort to minimize
site grading and impact to the wetlands. The revised plans should be available for review by
Monday, March 25, 1996. The applicant's engineer has prepared a stormwater management plan
in accordance with the City's Surface Water Management Plan (SWMP). Detailed ponding
calculations were submitted for staff review and approval. Stormwater runoff from the site will
be conveyed via a storm sewer system to stormwater quality ponds for treatment prior to
discharging into the wetlands.
UTILITIES
As a part of the City's Bluff Creek Trunk Sanitary Sewer and Water Improvement Project, utility
service has been installed along Hunter Drive. The applicant has also submitted detailed
construction plans and specifications for extension of utility service along Longacres Drive and
future extension to the north of this development. The City's Comprehensive Plan calls for a
16 -inch trunk waterline to be installed along Longacres Drive eventually out to Galpin
Boulevard. The applicant is proposing to install a portion of this 16 -inch trunk line in
conjunction with this phase of development. The City, in the past, has typically compensated
developers for installing portions of the trunk utility system. Therefore, the applicant should be
entitled to a credit against existing or levied assessments on the property for the cost difference
between an 8 -inch waterline versus a 16 -inch waterline.
Extension of utilities is proposed outside of the street right -of -way. Staff has reviewed the
construction plans and determined that drainage and utility easements widths will need to be
increased to provide adequate room for access and maintenance, specifically over Lot 2, Block 1,
Lots 4, 5, 6, and 7, Block 2, and Lots 1, 2, and 3, Block 3. Staff has described the individual
easements necessary over these lots in the conditions of approval.
Staff has received detailed street and utility construction plans and specifications for this phase.
Upon review of the plans, staff found the plans and specifications acceptable with a few minor
modifications. The construction plans have been sent back to the applicant's engineer for
revisions. The revised construction plans should be available for review and formal approval at
the City Council meeting on March 25, 1996. Staff has prepared a development contract/PUD
agreement for the applicant to enter into. The development contract/PUD agreement is also on
the agenda for review and approval by the City Council on March 25, 1996.

This phase of development involves extending Longacres Drive and Hunter Drive. Future
phases will continue Longacres Drive out to Galpin Boulevard (County Road 117). Longacres
Drive is listed in the City's Comprehensive Plan as a collector street. This street :is also
designated as a Municipal State -Aid Route. Therefore, parking will be prohibited on both sides
of Longacres Drive. The City Council will need to adopt a resolution accordingly. Longacres
Drive is proposed with a 36 -foot wide, face -to -face street section versus the typical residential
31 -foot wide street section. The street's horizontal and vertical alignment is subject to approval
by MnDOT. A sidewalk is also proposed along the north side of Longacres Drive. Detailed
construction plans for the street improvements have been submitted to City staff for review and
approval. These plans will also be available for review and approval at the City Council meeting
on March 25, 1996.
