' LANDS CAPING PLAN AND WOODLAND MANAGEM PLAN
Loucks and Associates has prepared a landscaping plan. The landscaping plan needs to be
signed by a landscape architect. This plan has eight different species of trees but does not
indicate a quantity for each type. The overall landscaping plan is well conceived but staff has
the following modifications:
• Sugar Maples are shown in areas of wet soil conditions. These trees should be
substituted for more tolerant trees.
• The trees shall be placed on the site within the following ranges:
' Species Range
American Linden 49-65
Littleleaf Linden
Sugar Maple 49 - 65
' Red Oak 19 -49
White Oak
' Black Hills Spruce 39 -49
Norway Spruce
Red Cedar
Weeping Willow - - 0 - 11
' The developer shall provide accounting of the trees being utilized. They shall also provide a
matrix of the block, lot, number and type of trees being placed on lots.
The applicant has prepared a Woodland Management Plan. Staff is recommending
modifications to the plan acceptable and approved by staff prior to recording.
' Sugar Maples in the wet soils shall be modified to other species including Swamp
White Oak, Linden, River Birch, Silver Maple or Red Maple.
• Tree conservation easements are required on Lots 4 -8, Block 3. In addition tree
' removal plans for these lots shall be provided. At the time of building permit
application, the builder shall provide canopy removal calculations and tree
removal/preservation plan. If trees removed in these lots exceed the original canopy
' coverage, trees shall be replaced at a 2 to 1 ratio.

The final drainage plans have incorporated staffs directions as far as ponding, storm sewer
construction and minimizing drainage impacts to the adjacent parcels. The plans have also
included temporary sediment basins at the west end of the project to pretreat runoff prior to
discharging into the wetland located in Victoria. These temporary sediment basins will be
used during site construction and will be abandoned once the project has been fully
revegetated. Stormwater discharge from the site will maintain the predeveloped runoff rate
after the project is completed in compliance with the SWMP.
The applicant and staff have come to a resolution to improve the existing drainage underneath
Kings Road through the Morgan/Scott parcel. Currently, stormwater runoff from the site
drains underneath Kings Road via a 24 -inch culvert through the Morgan /Scott parcel en route
to Lake St. Joe. The plans propose on rerouting this stormwater runoff via storm sewer
easterly along Kings Road to outlet east of the Morgan /Scott parcel on what will become city
parkland adjacent to Lake St. Joe (Outlot A). The existing 24 -inch culvert underneath Kings
Road will be removed.
At the time of preparing this report, review of the stormwater ponding calculations has not
been completed by staff. Staff is confident that the site has adequate room to provide the
necessary ponding areas. The SWMP water quality /quantity connection fees will be adjusted
once the ponding calculations and construction plans have been approved by staff. Additional
SWMP credits are also being given for the additional storm sewer required to reroute the
stormwater east along Kings Road. A breakdown of these credits will be generated after staff
approval of the construction plans.
The majority of the site is proposed to be graded for development of the streets, storm pond,
and house pads. The wooded area in the northwest corner of the site will be preserved for
now. These lots (Lots 4 through 8, Block 3) will be custom graded at time of building to
minimize tree loss. Individual tree removal, grading, drainage, and erosion control plans will
be required for review and approval by the City in conjunction with applying for and
obtaining a building permit. Tree preservation easements will also be required over these lots.
In an effort to minimize erosion and ensure proper drainage, staff has implemented a new
policy requiring that the entire site must be graded in accordance with the approved grading
plan and all disturbed areas reseeded /sodded and mulched prior to issuance of building
permits with the exception of one model home permit. This condition has been incorporated
into the development contract.

Since the construction window for this season is half over, the applicant has requested,
contingent upon final plat approval, that they be permitted to commence with site grading
prior to recording of the final plat documents. The City has allowed this in the past
' contingent upon the applicant entering into the development contract and supplying the City
with a financial security to guarantee site grading, erosion control, and site restoration.
'
UTILITIES
L.ITIES
The applicant has provided the City with detailed construction plans and specifications. Staff
has reviewed the plans and finds them in general conformance with City standards. However,
the plans still require some relatively minor changes. Staff requests the City Council grant
staff the flexibility to administratively approve the construction plans and specifications after
' the necessary changes are made.
Plans are providing utility stubouts for the future extension to adjacent parcels north
(Hallgren) and east of the site (Headla/Wenzel). In conjunction with the parkland acquisition,
the City is entering into a cost sharing agreement with the applicant for reimbursement of
'
50% of the utility and street costs along Kings Road adjacent to the parkland. Final City
participation will be determined upon completion of the project when the actual quantities
have been determined. The 50 -50 cost share will also apply to engineering, inspection and
' legal costs as well. The City will pay a prorated percentage of these fees based on the overall
project costs.
' The applicant is also constructing a lift station to service this development and areas outside
of the plat (approximately 10 acres). The City has required the applicant to increase the lift
station depth and possibly the size of the pumps to facilitate future use. The City will
' compensate the applicant a prorated share of the cost of the lift station for this oversizing
cost. In addition to the lift station, the City has required a telemetry system to be
incorporated into the lift station construction. Telemetry systems have been installed and are
operating in all of the City's lift stations and well houses. The cost of this telemetry system
will also be cost shared on a prorated basis.
' Plans are also providing utility stubouts for the individual houses along Kings Road
(Morgan /Scott). According to city ordinance, parcels within 150 feet of the utilities must
hook up to the new utilities within 12 months after the system becomes operational. The
' property owners, Ms. Morgan and Ms. Scott, have been notified of this requirement and have
communicated to staff that they wish to receive a variance to this ordinance. Staff has
provided them with copies of the ordinance and direction to request a variance from such
requirement. Staff has reviewed the building permit file and found that the current septic
system on site is a relatively new system and at this point should not be required to be
abandoned. The City in the past has deviated from this ordinance as long as the current
The Oaks of Minnewashta
Final Plat

Page 8
septic system meets code and the property owner supplies the City with documentation bi-
annually that a current septic system is maintained and operating properly. Staff recommends
that the property owners submit a written request for a variance consideration from this
ordinance to the city engineer.
Utilities with the first phase will extend sewer and water service along Kings Road
approximately 1,100 feet west of Minnewashta Parkway (intersection of Country Oaks Drive).
The second phase will continue the utility service westerly along Kings Road.
The grading plan does provide for erosion control measures. Erosion control fences,
temporary sediment basins, and permanent stormwater ponds have been proposed. All
disturbed areas shall be immediately restored with seed and disc - mulched or sod within two
weeks of completing site grading.
Access to the development is proposed from Kings Road which is a narrow gravel roadway
between 20 -30 feet wide. As a part of this development, Kings Road is proposed to be
upgraded to an urban street to adequately address traffic and meet subdivision ordinance
requirements. During the street construction, access will be maintained on a portion of Kings
Road. However, the road width will be narrowed down to 14 feet in width. Utility lines
have been shifted northerly to minimize impact to the properties to the south and maintain the
gravel surfaced road for the existing residents along Kings Road.
The applicant is dedicating the necessary right -of -way along Kings Road in the interior streets
with the final plat. The City has compromised on the right -of -way width of Kings Road as a
part of negotiations. The applicant will be constructing Kings Road only up to Country Oaks
Road at this point. Phase II ( Outlot B) of the development will require the upgrade of Kings
Road and utility extension. Outlot B may be subject to assessments for the cost of upgrading
Kings Road in the future if the City is petitioned to do a 429 assessment project. The
applicant should escrow with the City their fair share of the cost to extend Kings Road west
of Country Oaks Road or a conveyance placed on the deed of Outlot B that these future lots
will be responsible for 50% of the cost to upgrade Kings Road west of Country Oaks Road.
Plans propose on extending future street service to the Hallgren parcel to the north. A street
extension is also being provided on the east side of this development to provide access to
Headla/Wenzel properties. A temporary cul -de -sac is proposed at the east end of White Oak
Lane. A sign will be placed on the barricade indicating that "This street will be extended in
The Oaks of Minnewashta
Final Plat
' July 18, 1995
Page 9
the future." This condition will also be listed in the development contract to notify future
property owners of this future roadway extension.
' With the exception of Kings Road, street grades are within the City's ordinance. On Kings
Road, the street was designed to be compatible with the existing topography which resulted in
the street grades between 0.5% and 9.5 %. Staff recommends a variance to the city ordinance
be approved.
' MISCELLANEOUS
The landscape plan proposes numerous landscaping plantings within drainage swales and over
proposed utility lines which run along the rear lot lines and side lot lines. Staff recommends
that the landscape plan be revised to relocate planting materials so they are not over the
proposed utility lines or within drainage ways.
As a part of the parkland negotiations, certain conditions have been negotiated as part of the
transaction. It will be the applicant's responsibility to remove the existing structures from the
site and disconnect the utility services from each dwelling. In addition, the applicant shall be
responsible for the abandonment of the existing wells and septic systems in accordance with
local and state health codes. Upon razing of the structures on the park property, all debris
shall be removed off site and the basements backfilled with clean fill material. The City will
' reseed the areas where the structures existed. The demolition of these existing structures on
the park property shall be completed within 30 days after the final plat has been recorded.
' The applicant and City are proposing to close on the parkland once the final plat has been
recorded. In the meantime, staff recommends that prior to recording the final plat, the
applicant should enter into a purchase agreement with the City for acquisition of Outlots C
and D. Outlot A should be conveyed to the City for drainage, utility, and park purposes in
conjunction with the City filing the final plat.
The construction of the lift station located on the westerly end of Kings Road on Outlot B
will require additional drainage and utility easements on Outlot B. The final plat shall reflect
a 20 ft. x 20 ft. area located in the southwest corner of Outlot B for the lift station.
' A neighborhood meeting was held on Wednesday, July 19, 1995 at 6:00 p.m. in the City
Council Chambers to discuss the project. Discussion items at the meeting included the
' project scheduling, access during construction, construction impacts to existing trees along
Kings Road and contractor's construction yard. The major concern was access during
construction. The applicant and city staff heard the concerns and will follow up with the
contractor to ensure their concerns are addressed.

Oaks of Minnewashta
Woodland Management Plan
Introduction
Oaks of Minnewashta is a 45 unit single- family subdivision with an 8.21 -acre park and an outlot
for future development o£7 homes (52 homes total). The project is located on the northwest
corner of Kings Road and Minnewashta Parkway. As developer of this upscale neighborhood,
Harstad Companies is committed to tree preservation and protection of the natural woodlands and
steep slopes of the site. The residential subdivision was designed to minimize the impact to the
existing hardwood forest on the northwestern corner of the site.
Oaks of Minnewashta Tree Preservation Philosophy
Harstad Companies finds that trees provide many benefits including: stabilization of the soil by the
prevention of erosion and sedimentation, reduction of storm water runoff and the costs associated
therewith, improvement of air quality, reduction of noise pollution, control of urban heat island
effect, protection and increase of property values, privacy, energy conservation through natural
insulation, control of drainage and restoration of denuded soil subsequent to construction and
grading, protection from severe weather, protection of habitat for birds and other wildlife,
conservation and enhancement of the city's physical and aesthetic environment, reforestation of
open lands, and consideration for the quality of life and general welfare of the city.
Oaks of Minnewashta Tree Preservation and Landscape Plan
Harstad Companies through Loucks and Associates, Inc., prepared a tree preservation and
landscape plan dated July 10, 1995. This plan identifies the areas of proposed tree canopy
protection. The plan also identifies the base landscape replacement plan which shall be installed
by the developer. The species were specifically selected based upon compatibly with the existing
natural conditions and for promoting a quality hardwood tree environment throughout the
subdivision.
A variety of hardwood upland tree species have been selected to provide an overstory tree
canopy. With a total of 197 plantings, the tree species are dominated by varieties of Maple, Oak,
Linden, and Spruce as indicated on the Landscape Platt. The Plan also proposes to plant 1. l
weeping willows along the perimeter of the storm water pond adjacent to the city park. These
trees were selected for their compatibility with the existing soil and hydrology conditions.

Individual lots are anticipated to be landscaped by the builders/homeowners according to their
' specific landscape ideas, as long as they comply ed esandlt�he number of
trees
s along Country
lot. In some cases, such as with the willo
Oaks Drive (noted below under Other Plantings), builders/homeowners will be obligated to
' specific plant varieties. The Landscape Plan proposes to plant an average of 3,79 trees per lot
throughout the project.
' Sc re ening Ad iacent Neishb orhaod_s
The Landscape Plan was designed to buffer existing neighborhoods adjacent to the site. The
■ following plantings are proposed to occur subsequent to mass grading of the site.
• The plan shows a cluster of trees along the western edge, lying in Lots 9, 23, and 24, Block
3, along the border of the City of Victoria. Harstad Companies proposes to plant 11 Sugar
Maples and 8 Norway Spruces. These species were selected for their ability to survive in
fairly wet soil conditions.
• The row of trees along the rear lot lines of Lots 1 - 4, Block 2 will also be planted
immediately after mass grading. Specifically there will be 9 deciduous trees and 7 conifers
selected from the plantings list to best meet local conditions.
• The 11 willow trees near the storm water pond adjacent to the park site.
Phase 2 lout of B
Phase 2 is scheduled for development within the next three years. It is proposed that planting of
these trees will occur when that portion of King's Road is upgraded and new home construction
begins. The Landscape Plan shows a total of 32 plantings on this outlot, 'including the entire row
of trees along the rear lot line of these lots.
Other Plan in s
Besides the trees noted above (under the headings Screening Adiacen Neighborhoods and Phase
2 ( Outlot B )), the remaining trees will be planted in conjunction with final landscaping of each lot.
This will help ensure that homebuyers can coordinate plantings with their specific landscaping
needs and guarantee the successful continued maintenance of the trees. Harstad Companies will
attach an addendum to the sale of each lot requiring Builders and Homebuyers to meet the
requirements of the overall Landscape Plan.
All builders and homebuyers who purchase a lot adjacent to Country Oaks Drive, whether or not
that lot is accessible from Country Oaks Drive, shall be obligated to plant at least one oak tree on
the common property line with Country Oaks Drive.

.JUL 14 '95 12:54 TO 612 937 5739 FROM HARSTAD COMPANIES T -807 P.04
future homes are anticipated to be designed specifically for each lot to minimize the grading and
disruption to the significant trees outside the designated home pads. Builders will be notified that '
removal of any trees not already accounted for must be replaced per City ordinance.
Trees designated for preservation shall be marked with "tree preservation" ribbon with clearly '
marked signage specifying that the area is off limits for construction activities. Protective barriers
must be located at the perimeter of the building pad and driveway area in order to completely '
protect trees being saved and must remain in place until all construction activities are terminated.
No equipment, chemicals, soil deposits, or construction materials shall be placed within the
protective barriers. Any understory trees and natural vegetation should be preserved within the
boundaries of the protective areas. A preservation plan for lots 4, 5, 6, 7, and 8, Block 3 may
include the use of retaining walls, requirement for post - construction deep root fertilization and
soil aeration, or construction vehicle ramp systems. Preservation plans for the 5 above - mentioned '
lots will be established at the time of building permit application. An individual grading, drainage,
and erosion control plan will be required for these 5 lots prior to issuance of building permits.
