1. EXECUTIVE SUMMARY
The Fish Point Road (CSAH 44 to TH 13) Reconstruction Project includes the reconstruction of Fish Point
Road SE from 160th Street SE (CSAH 44) to MnDOT Trunk Highway 13 (TH 13). The project also
includes the reconstruction of the local streets that access Fish Point Road SE in this area. These streets
include: Hidden Oaks Circle SE, Timberview Street SE, Millers Circle SE, Glory Circle SE, Timber Trail
SE, and Omega Trail SE. All streets within the project area currently exist as urban street sections.
The reconstruction of the streets and the utilities is identified in the City’s Capital Improvement Plan
(CIP) for construction in 2021. The project is proposed to be constructed in two phases, due to funding
constraints relating to other non-programmed street improvement needs within the downtown area. The
local streets are proposed for reconstruction in 2021, and Fish Point Road is proposed for recons truction
in 2023.
Roadway reconstruction, consisting of removal of the existing bituminous pavement, subgrade correction,
replacement of concrete curb and gutter, and new bituminous pavement is proposed for all streets within
the project area, totaling approximately 7,230 feet (1.37 miles). The sidewalk along Fish Point Road SE is
also proposed to be replaced with this project. Existing public retaining walls within the project area will be
replaced as necessary to construct the public improvements.
A map showing the project location can be found on Figure 1 in Appendix A.
Replacing portions of the City’s deteriorating utility infrastructure in conjunction with the proposed street
improvements provides an opportunity to minimize the replacement costs and traffic disruptions
associated with the work. Proposed utility improvements include the following:
▪ Installation of new watermain
▪ Replacement of hydrants, gate valves, and utility services as necessary
▪ Repair or installation of storm sewer to improve overall drainage and meet State Aid design
standards along Fish Point Road
▪ Lining of PVC sanitary sewer pipe and replacement of VCP sanitary sewer pipe
▪ Spot sanitary sewer repairs as necessary
▪ Replacement of public retaining walls as necessary to construct the public improvements
▪ Intersection improvements at Fish Point Road and TH 13 to facilitate the construction of
dedicated turn lanes for northbound and southbound traffic onto TH 13 from northbound Fish
Point Road, and a dedicated through lane for southbound traffic onto Fish Point Road from TH 13
The proposed improvement cost for reconstructing the local streets in 2021 is estimated to be
$4,391,245.06, and the proposed improvement cost for reconstructing Fish Point Road in 2023 is
estimated to be $6,325,998.49. These estimates include a 10% contingency and 28% indirect costs, and
the 2023 construction estimate includes an assumed 2.6% inflation rate. Funding for the project will be
provided through assessments to benefiting properties, tax levy , State Aid funds, and various City funds.
Phase 1 of the proposed project is scheduled to begin construction during the spring of 20 21, with local
street reconstruction being substantially complete by September 2021. The final wear course of
bituminous pavement on the local streets will also be placed in the fall of 2021. Reconstruction of Fish
Point Road is scheduled to begin in the spring of 2023, with subs tantial completion scheduled for
September 2023. The final wear course will also be in the fall of 2023. This project is feasible,
necessary, and cost-effective from an engineering standpoint and should be constructed as proposed
herein.

2. INTRODUCTION
2.1 Authorization
On August 19, 2019, the City of Prior Lake City Council authorized the preparation of a feasibility report
for the Fish Point Road (CSAH 44 to TH 13) Reconstruction Project in Resolution 19-095. This project
has been designated City Project No. TRN 20-000001.
2.2 Scope
This report investigates the feasibility of proposed improvements to street and utilities identified within the
City’s Capital Improvement Plan. The streets proposed for the Fish Point Road (CSAH 44 to TH 13)
Reconstruction Project were initially considered because of existing pavement conditions and known
utility failures. The project includes the following streets .
▪ Fish Point Road SE from 160th Street SE (CSAH 44) to Trunk Highway 13 (TH 13)
▪ Hidden Oaks Circle SE from Fish Point Road SE to the cul-de-sac
▪ Timberview Street SE from Hidden Oaks Circle SE to the cul-de-sac
▪ Millers Circle SE from Fish Point Road SE to the cul-de-sac
▪ Glory Circle SE from Fish Point Road SE to the cul-de-sac
▪ Timber Trail SE from Fish Point Road SE to the terminus
▪ Omega Trail SE from Fish Point Road SE to the cul-de-sac
The project area is shown in Figure 1 of Appendix A.
Improvements within this report include roadway reconstruction, public retaining wall replacement,
concrete sidewalk replacement, sanitary sewer lining improvements, watermain replacement, storm
sewer improvements and intersection improvements at Fish Point Road and TH 13.
2.3 Data Available
Information and materials used in the preparation of this report include the following:
▪ City of Prior Lake Capital Improvement Plan
▪ City of Prior Lake Assessment Policy
▪ City of Prior Lake Property Index Records
▪ City of Prior Lake Topography Maps
▪ City of Prior Lake Sanitary Sewer Televising Reports

2.4 Background
The City of Prior Lake has developed a Capital Improvement Plan to maintain infrastructure within the
City. The proposed project area has been identified as a potential street reconstruction project location,
where the streets are proposed to be reconstructed and issues with utilities addressed.
The City of Prior Lake utilizes a Pavement Management Program to rate the condition of the City’s
streets. The pavement rating, known as Overall Condition Index (OCI), is determined based on the
amount of pavement deterioration that is visually evident. The street OCI is a number between 0-100,
with 100 indicating streets that are in the best condition or are newly paved and 0 being the worst. Streets
in need of a mill and overlay generally have an OCI of 45-65 and streets with an OCI between 35-45

usually require a full depth reclamation. When the OCI reaches a range of 0 -35 or when utility repairs are
needed, the street usually requires a full reconstruction.
A detailed account of the OCI values for the project area is shown in Table 1.

3. EXISTING CONDITIONS
3.1 Surface
The pavement within the proposed improvement area is aging and exhibiting alligator cracking, edge
cracking, transverse cracking, longitudinal cracking, stripping (that has since been patched) and some
rutting. The bituminous pavement is becoming more brittle due to age and is showing signs of
accelerated deterioration. The concrete curb and gutter is in overall poor condition, with locations of
cracking and settling. The northern portion of Fish Point Road SE includes medians and turn lanes onto
Omega Trail and Trunk Highway 13. The medians are in overall poor condition and show cracking in both
the curb and interior concrete. A summary of existing conditions by street is provided in Table 1.

A geotechnical report was completed by WSB in March of 2020. A total of 18 soil borings were taken at
various locations throughout the project area. The borings indicate bituminous pavement thicknesses
from 3 inches to 10 inches. Underlying the pavement was approximately 4.5 inches to 24 inches of
aggregate base. The borings showed lean clay and some sand material below the aggregate. The full
report can be found in Appendix B.
3.2 Public Utilities
The City of Prior Lake owns, operates and maintains storm sewer, sanitary sewer, and watermain within
the project area.
3.2.1 Storm Sewer and Drainage
Existing and aging storm sewer infrastructure exists within the project area. The storm sewer was
installed between 1980 and 1986. Stormwater runoff in the project area is collected into a storm
sewer system and is generally discharged to stormwater basins and wetlands located east of Fish

City of Prior Lake
WSB Project No. R-13977-000 5
Point Road. Stormwater from the northern portion of Fish Point Road and Omega Trail is
conveyed by storm sewer across TH 13 and into Lower Prior Lake.
Based on field observations, the existing storm sewer is fair-to-poor condition and will need to be
upgraded to properly collect and convey stormwater for the proposed roadway and pedestrian
improvements. Many of the outfalls from the project area will likely be able to be connected to, in
effort to utilize some of the existing system and avoid private property impacts.
The project is located entirely within the Prior Lake Spring Lake Watershed District (PLSLWD).
3.2.2 Sanitary Sewer
The sanitary sewer system within the project area was constructed between 1972 and 1984 and
consists primarily of 8-inch vitrified clay pipe (VCP) and 8-inch polyvinyl chloride pipe (PVC). The
sanitary sewer on Fish Point Road SE between Millers Circle SE and Trunk Highway 13 is 9-inch
VCP. The sanitary sewer for the project area flows north towards the sanitary sewer at Trunk
Highway 13, which then flows south along TH 13 via City-owned trunk sanitary sewer facilities to
CSAH 21, where the system then connects to the MCES gravity interceptor system that flows
west and north to exit the City. The existing sanitary sewer pipe and manholes are in fair
condition.
3.2.3 Watermain
The watermain system within the project area was installed between 1972 and 1986. The existing
watermain on Fish Point Road SE consists of 8-inch ductile iron pipe and 8-inch cast iron pipe.
The existing watermain on Hidden Oaks Circle SE and Timberview Street SE consists of 8-inch
cast iron pipe. The existing watermain throughout the rest of the project in 6-inch ductile iron pipe.
3.3 Street Lighting
Street lights on utility poles exist on Fish Point Road SE from CSAH 44 to Huron Street SE. Decorative
street lamps exist on Hidden Oaks Circle SE and Timberview Street SE.
3.4 Sidewalks
Between CSAH 44 and Huron Street SE, 5-foot concrete sidewalks with boulevards exists on both the
west and east sides of Fish Point Road SE. Between Huron Street SE and Trunk Highway 13, the
boulevard between the existing 5-foot concrete sidewalk and the face of curb varies from 0-feet to 5-feet
in width. In some locations, the sidewalk extends from the back of curb to the face of existing retaining
walls.
3.5 Private Utilities
Private utilities that have facilities in or near the project area will be notified during the final design phase
of the project and will be requested to coordinate any necessary repairs and replacements as needed at
their cost. Private utility companies that may have facilities, both underground and aerial, within the
project area include the following:
▪ Center Point Energy (Gas)
▪ CenturyLink (Telephone)
▪ Mediacom (Fiber Optic/Cable)
▪ Minnesota Department of Transportation (Signals)
▪ Scott Rice/Integra Telephone (Telephone)
▪ Xcel Energy (Electric)
▪ Minnesota Valley Electric (Electric)
▪ Zayo (Telecom)

4. PROPOSED IMPROVEMENTS
4.1 Streets
Fish Point Road SE is proposed to be reconstructed with a 12-inch sand section, a 12-inch aggregate
section, 6 inches of bituminous pavement, and barrier style concrete curb and gutter. Geotextile fabric will
be used to separate the existing subgrade and the new street section. Between CSAH 44 and Huron
Street SE the roadway will have 21.5-foot wide traffic lanes to match the existing roadway section that
accommodates on-street parking adjacent to the two middle schools. Between Huron Street SE and
Trunk Highway 13, the roadway will have 14-foot wide traffic lanes with no on-street parking. The typical
sections for these designs are shown in Figures 2 and 3 in Appendix A.
For all other streets in the project area, the roadways will be reconstructed with a 24-inch sand section, a
6-inch aggregate section, 4 inches of bituminous pavement, and barrier style concrete curb and gutter.
The roadways will be constructed to have 14-foot wide traffic lanes. The typical section for the proposed
local street design is shown in Figure 4 in Appendix A.
The street section designs are based on soil conditions found from the soil borings (see Appendix B), the
traffic volumes, previous project experience in the area, and City standards. Within the project, the
reconstructed roadway grades will be designed in such a way to minimize impacts to existing
neighborhood features such as trees, landscaping, and driveways. Minor modifications to the existing
alignment and roadway profile for Fish Point Road will be made to meet current State Aid design
requirements. All impacted public retaining walls will be reconstructed based on the recommendations
provided in the Geotechnical Report (see Appendix B).
Drain tile will be installed with all new street sections within the project area to provide adequate drainage
for the roadway subgrade and extend the useful life of the roadway section.
Permanent driver feedback signs (DFB) are proposed to be installed along Fish Point Road as a part of
the project. In the past, City Staff has installed temporary DFBs have been installed along Fish Point
Road in response to resident concerns regarding vehicle speeds within the corridor. As a part of the
improvement project, permanent DFBs will be installed, similar to what was installed along Franklin Trail
south of CSAH 44 (160th).
4.1.1 Right-Of-Way
Right-of-way needs, if any, will be identified during the final design process. Temporary
construction easements or waivers of trespass may be required for grading purposes to provide
positive slopes to the curb and to address issues with existing retaining walls. Temporary
construction easements may also be necessary along the lot lines in which runoff outlets.
4.1.2 Retaining Walls
Public retaining walls within the project area proposed to be replaced when impacted by either
street or utility construction. Precast Modular Block Walls (PMBWs) will be installed and will
match walls installed with other recent public improvement projects. It is anticipated that there
will be impacts to existing vegetation associated with wall excavation and construction. Fencing
will be installed atop of retaining walls greater than or equal to four-feet in height to provide the
necessary fall protection.
4.2 Public Utilities
The City of Prior Lake owns, operates and maintains storm sewer, sanitary sewer, and watermain within
the project area. The improvements to these utilities are summarized below.
Feasibility Report
Fish Point Road (CSAH 44 to TH 13) Reconstruction Project
TRN#20-000001
City of Prior Lake
WSB Project No. R-13977-000 7
4.2.1 Storm Sewer and Drainage
Reconstruction of the streets provides the opportunity to improve the drainage within the project
area through the installation of new or additional storm sewer facilities. Proposed drainage
improvements include installation of new storm sewer collection and conveyance systems and
reconstructing or replacing existing catch basins where the infrastructure is in acceptable
condition and meets the needs of the proposed improvements.
Stormwater management improvements will be implemented to achieve the requirements of the
Prior Lake Spring Lake Watershed District (PLSLWD) as well as the NPDES and MS4
requirements of the Minnesota Pollution Control Agency (MPCA). Rate control will be provided to
ensure proposed discharge rates are less than existing condition or that downstream facilities
have the required capacity. Volume control and water quality treatment will be provided to meet
the needs of the project. Stormwater credits from previous public improvements projects will be
used as appropriate and available to meet the volume control and water quality treatment
requirements for this project. A decrease in impervious surface would achieve the requirements
of the MS4 permit. If this does not occur, additional stormwater treatment may need to be
incorporated.
Temporary erosion and sediment control devices will be utilized during construction in
accordance with pertinent MPCA NPDES General Construction permit requirements.
The costs for the proposed storm sewer improvements are included in Appendix C.
4.2.2 Sanitary Sewer
The proposed sanitary sewer improvements consist replacing a majority of the VCP sewer pipe
and lining the existing PVC sewer pipe within the project area. Spot repairs will be made to the
PVC sewer pipe in locations where lining the existing sewer pipe is not feasible due to sags or
joint separation. Sanitary sewer that exists in easements between properties are proposed to be
lined to limit impacts to trees, landscaping, and other private improvements in these areas. It is
the City of Prior Lake’s practice to replace all sanitary sewer services to the right-of-way with the
road reconstruction projects. Parcels that may be subdivided in the future will receive additional
services based on the size of the lot. The costs for sanitary replacement are included in
Appendix C.
4.2.3 Watermain
New 8-inch PVC watermain is proposed along all reconstructed roadways. Full watermain
replacement including replacement of all water services and curb boxes within the project area
are proposed as part of the improvements. Temporary water services will need to be provided to
maintain service to the affected properties while the main is replaced. Hydrants, valves, and
services will also be replaced in these areas as needed. All parcels will receive a new service to
the right-of-way. Parcels that may be subdivided in the future will receive additional services
based on the size of the lot. The costs for watermain replacement are included in Appendix C.
4.3 Street Lighting
The streetlights that exist along Fish Point Road SE are limited to that portion of the road between CSAH
44 and Huron Street SE and the intersections at Hidden Oaks Circles SE and Trunk Highway 13. The
replacement of existing streetlights and the addition of new streetlights, especially at intersections, has
been standard practice with past improvements projects within the City. Street lighting is proposed to be
installed along all streets in the project area according to the City standard spacing. The proposed
streetlights for the project will be a combination of rectilinear style and decorative traditional lights, both of
which will have LED style bulbs. Streetlights will be owned and maintained by the electric service
providers for this area (Xcel Energy and Minnesota Valley Electric).

City of Prior Lake
WSB Project No. R-13977-000 8
4.4 Sidewalks
The replacement of the 5-foot wide concrete sidewalk is proposed along Fish Point Road SE. From
CSAH 44 to Huron Street SE, a 5.5-foot boulevard is proposed between the face of the curb and the edge
of the sidewalk. Between Huron Street SE and Trunk Highway 13, the boulevard width will vary between
being 0.5-feet wide and 5-feet wide, such that the sidewalk will be reinstalled in a similar location to
preconstruction conditions where adjacent retaining walls and right-of-way locations limit the creation of
boulevard spaces between the roadway and the sidewalk. Pedestrian curb ramps meeting current ADA
standards will be constructed at sidewalk connections with the residential streets.
For the purposes of this report, the costs associated with installing a new concrete sidewalk along the
west side of Fish Point Road from Huron Street to TH 13 have been included in the total project costs.
Additional right-of-way, driveway impacts and retaining wall needs associated with the construction of
such a sidewalk will be evaluated with final design of the project to determine if sidewalk extension will be
included in the final scope of work.
4.5 Intersection Improvements
The medians and turn lanes at the Fish Point Road SE and Timber Trail SE/Omega Trail SE and at Fish
Point Road SE and Trunk Highway 13 are proposed to be removed and/or reconfigured with this project.
The median south of Omega Trail SE is proposed to be eliminated and replaced with pavement markings,
while the northern median will be relocated to allow for the construction of a dedicated southbound left
turn lane onto Timber Trail SE, as well as dedicated north and southbound turn lanes onto TH 13 from
northbound Fish Point Road. See Figure 4.5.1 on the next page.

4.6 Permits/Approvals
The anticipated permits and approvals, and the respective regulatory agencies, are listed below:
▪ Minnesota Pollution Control Agency (NPDES) ............................... Erosion/Storm Water Permit
▪ Minnesota Department of Transportation (TH 13) ...................................... Right-of-Way Permit
▪ Scott County (CSAH 44) ............................................................................. Right-of-Way Permit
▪ Minnesota Department of Health ............................................... Extension of Watermain Permit
▪ Prior Lake Spring Lake Watershed District……………..Stormwater and Erosion Control Permit
In addition to a Right-of-Way Permit, the City will work with MnDOT to obtain the necessary approvals
associated with the intersection improvements at Fish Point Road and TH 13, including the relocation of
the existing signal arm to facilitate the construction of north and southbound turn lanes onto TH 13 from
Fish Point Road.
4.7 Construction Access/Staging
A detour for Fish Point Road SE will be necessary to keep non-local traffic from entering the project area
and to maintain access to the middle school sites during construction.
All streets in the project area will be closed to “Local Traffic Only” during construction. The neighborhood
will experience times during utility and retaining wall construction and other work tasks where ingress and
egress is restricted during the day. Alternative routes through the neighborhood may need to be utilized
to access driveways.
Access to driveways will be restricted during and after concrete curb and concrete driveway patches are
poured.
City Staff will work with ISD #719 to coordinate bus access and construction activities during the 2021 -
2022 and 2023-2024 school years. City Staff will also work with the school district to coordinate access
to both middle schools during the summer months to ensure planned Community Education offerings at
the middle school can continue, in addition to planned athletic club use of the middle school sites and
Lakefront Music Fest Parking.
It is anticipated that construction activities throughout the project area will be phased during the 2021
construction season. Additional details regarding phasing and detour plans will be developed with the
final design of the project.
4.8 Public Involvement
A public informational meeting for the proposed project was conducted by the City on January 23, 2020.
Preliminary information was presented to attendees regarding the proposed improvements , funding
sources, schedule, and impacts associated with the project. Minutes from the Question and Answer
portion of the meeting are included in Appendix E of this report. A second public informational meeting
was conducted by the City on August 19, 2020. This meeting was an “open-house” style and residents’
questions were answered, and input was gathered. On August 5, 2020, in-person meetings were
scheduled and conducted with those residents who requested them. A summary of these meetings is
included in Appendix E of this report.

7. FEASIBILITY AND RECOMMENDATION
The improvements proposed in this study are necessary for a number of reasons. The reconstruction of
the streets within this project provides the City with a cost-effective means of continuing the City’s street
improvement efforts and ensuring an adequate means of transportation for local residents. The
reconstruction of utilities within the area is ideal at this time due to the reconstruction of the road and the
worsening state of the existing utilities. These improvements will provide a longer lasting product needing
less maintenance over time.
The proposed improvements constitute a project large enough to ensure a competitive bidding
environment, economies of scale, and are deemed to be cost-effective. Based on the information
contained within this report, the proposed project is deemed necessary, cost-effective, and feasible from
an engineering standpoint. The project feasibility is subject to financial review by the City.

1. INTRODUCTION
Project Location
The site is located along Fish Point Road between State Hwy 13 and 160th Street SE, as well as Timber
Trail SE, Glory Circle, Hidden Oaks Circle, Timberview Street, M illers Circle, and Omega Trail, all within
Prior Lake, Minnesota. The approximate soil boring locations can be found on the Soil Boring Exhibit in
Appendix A.
Project Description
It is our understanding that this project consists of reconstruction of Fish Point Road between State Hwy
13 and 160th Street SE, as well as reconstruction of Timber Trail SE, Glory Circle, Hidden Oaks Circle,
Timberview Street, Millers Circle, and Omega Trail. Along with pavement reconstruction and installation
of concrete curb and gutter, we understand the underground utilities (watermain, sanitary) will be
reconstructed across much of the project. Retaining walls along the roadway wi ll also be reconstructed.
We understand that the sanitary sewer within the southern half of the project is at depths of about 25 feet
below existing pavement grade.
We understand the horizontal and vertical alignment of the roadways will remain relativ ely unchanged
from existing conditions.
WSB has developed foundation recommendations for this project in consideration of the proposed layout,
loadings, and structural configurations as understood at this time. When the designer develops additional
information about final design structural loadings, building configuration, or other significant factors, the
recommendations presented herein may no longer apply. WSB should be made aware of the revised or
additional information in order to evaluate the recommendations for continued applicability.
Purpose and Project Scope of Services
Monica Heil with WSB requested these services which were authorized by Nick Monserud with the City of
Prior Lake. In order to assist the design team in preparing plans and specifications, we have developed
recommendations for retaining wall foundations, underground utilities and pavements. As such, we have
completed a subsurface exploration program and prepared a geotechnical report for the referenced site.
This stated purpose was a significant factor in determining the scope and level of service provided.
Should the purpose of the report change the report immediately ceases to be valid and u se of it without
WSB’s prior review and written authorization should be at the user’s sole risk.
Our authorized scope of work has been limited to:
1. Clearing underground utilities utilizing Gopher State One Call.
2. Mobilization / demobilization of a truck mounted drill rig.
3. Drilling 9 standard penetration borings to 20 foot depths.
4. Drilling 9 standard penetration borings to 30 foot depths.
5. Sealing the borings per Minnesota Department of Health procedures.
6. Perform soil classification and analysis.
7. Review of available project information and geologic data.
8. Providing this geotechnical report containing:
a. Summary of our findings.
b. Discussion of subsurface soil and groundwater conditions and how they may affect the
proposed underground utilities and pavements.
c. Estimated allowable bearing capacity of the soils.
d. Estimated excavation depths to suitable soils.
e. Estimated R-value of the soils.
f. Recommended pavement section.
g. A discussion of soils for use as structural fill and site fill.

2. PROCEDURES
2.1 Boring Layout and Soil Sampling Procedures
WSB completed 18 standard penetration soil borings along the proposed roadway improvement areas.
WSB recommended the boring depths and selected the desired locations. Our field crew staked the
borings by estimating from existing site features from the supplied site plan. The approximate boring
locations are shown on the Soil Boring Exhibit in Appendix A which is an aerial photo. The ground
surface elevations at the borings were estimated by using LIDAR data with 2 foot contours. These maps
should be accurate to within +/- one foot (1’) provided ground surface modifications at this site have not
been completed since LIDAR data was obtained. The borings were completed within the roadways and
were not completed at the base of any existing retaining walls.
We completed the borings between September 9 and September 27, 2019 with a truck-mounted CME-55
drill rig operated by a two-person crew. The drill crew advanced the borings using continuous hollow
stem augers. The drilling information is provided on the boring logs.
Generally, the drill crew sampled the soil in advance of the auger tip at two and one-half (2 ½) foot
intervals to a depth of 15 feet and then at five (5) foot intervals thereafter to the termination depth of the
boring. The soil samples were obtained using a split-barrel sampler which was driven into the ground
during standard penetration tests in accordance with ASTM D 1586, Standard Method of Penetration Test
and Split-Barrel Sampling of Soils. The materials encountered were described on field logs and
representative samples were containerized, and transported t o our laboratory for further observation and
testing.
The samples were visually observed to estimate the distribution of grain sizes, plasticity, consistency,
moisture condition, color, presence of lenses and seams, and apparent geologic origin. We classified the
soils according to type using the Unified Soil Classification System (USCS). A chart describing the USCS
is included in Appendix A.
2.2 Groundwater Measurements and Borehole Abandonment
The drill crew observed the borings for free groundwater while drilling and after completion of the borings.
These observations and measurements are noted on the boring logs. The crew then backfilled the
borings to comply with Minnesota Department of Health regulations.
2.3 Boring Log Procedures and Qualifications
The subsurface conditions encountered by the borings are illustrated on the Logs of Test Borings in
Appendix A. Similar soils were grouped into the strata shown on the boring logs, and the appropriate
estimated USCS classification symbols were also added. The depths and thickness of the subsurface
strata indicated on the boring logs were estimated from the drilling results.
The transition between materials (horizontal and vertical) is approximate and is usually far more gradual
than shown. Information on actual subsurface conditions exists only at the specific locations indicated
and is relevant only to the time exploration was performed. Subsurface conditions and groundwater
levels at other locations may differ from conditions found at the indicated locations. The nature and
extent of these conditions would not become evident until exposed by construction excavation. These
stratification lines were used for our analytical purposes and, due to the aforementioned limitations,
should not be used as a basis of design or construction cost estimates.

3. EXPLORATION RESULTS
3.1 Site and Geology
The borings were completed through the existing bituminous surfaced roadways. Approximate boring
elevations ranged from 946 to 996 feet, and indicate an undulating terrain.
Geologic origins can be difficult to determine solely from boring samples. We referenced online geologic
data of the area and used our experience to help determine geologic origin of the soils, however only a
detailed geologic exploration would accurately determine the geologic history of the site.
The Scott County Geologic Atlas indicates the surficial geology of the area is mostly bedrock consisting of
glacial till deposits consisting of a mixture of clay, silt, and sands. Gravels and cobbles are present in
areas and layers of lean clay or silt may be encountered.
3.2 Subsurface Soil and Groundwater Conditions
The boring profile generally consisted of the pavement section and fill materials overlying glacial till and
outwash deposits.
Pavement section
The pavement section generally consisted of bituminous asphalt overlying an aggregate base material.
The bituminous asphalt generally ranged from about 4 to 10 inches in thickness and averaged just over 6
inches. The aggregate base consisted of crushed limestone and natural granular soils consisting of
sands, sands with silt, and silty sands with various amounts of gravel. The aggregate base generally
ranged from about 4 ½ to 24 inches in thickness and averaged just over 8 inches.
Fill
The borings encountered fill materials at PB-01, PB-02, PB-03, PB-06, PB-12, PB-13, and PB-18. The
fills generally consisted of lean clays with sand, silty clays, organic clays, and clayey sands. The fills
were brown to dark brown to gray to black in color and generally moist to wet.
Glacial deposits
The predominate soils encountered in the borings were glacial deposits. These glacial till and outwash
deposits generally consisted of lean clays with sand, sandy lean clays, silty clays, clayey silts, clayey
sands, silty sands, and sands with various amounts of gravel.
These soils were brown to dark brown to reddish brown to gray in color and were generally moist to wet.

3.3 Strength Characteristics
The penetration resistance N-values of the materials encountered were recorded during drilling and are
indicated as blows per foot (BPF). Those values provide an indication of soil strength characteristics and
are located on the boring log sheets. Also, visual-manual classification techniques and apparent moisture
contents were also utilized to make an engineering judgment of the consistency of the materials.
Table 2 presents a summary of the penetration resistances in the soils for the borings complet ed and
remarks regarding the material strengths of the soils.

The preceding is a generalized description of soil conditions at this site. Variations from the generalized
profile exist and should be assessed from the boring logs, the normal geologic character of the deposits,
and the soils uncovered during site excavation.
3.4 Groundwater Conditions
WSB took groundwater level readings in the exploratory borings, reviewed the data obtained, and
discussed its interpretation of the data in the text of the report. Note that groundwater levels may
fluctuate due to seasonal variations (e.g. precipitation, snowmelt and rainfall) and/or other factors not
evident at the time of measurement.
The bore holes were only left open a short period of time, and groundwater levels may not have
stabilized.

NE – indicates ground water or gray colored soils were not encountered. Elevations rounded to the highest ½ foot.
Groundwater was encountered in Borings PB-02 and PB-06. Many of our borings encountered sands at
depth that were considered moist as opposed to wet or waterbearing, indicating a static groundwater level
is likely below the depths of those borings. We also noted gray colored soils in many of the other borings.
Gray colored soils can be an indication of long term saturation conditions and could show potential
groundwater elevations.
Lower Prior Lake is located approximately 500 feet north of the proj ect. Based on data from the
Minnesota Department of Natural Resources, Lower Prior Lake has an ordinary high water level of 903.9
feet. Based on this, it is our opinion that the groundwater encountered during drilling is likely a perched
groundwater table, however perched groundwater could have substantial volumes and may not be easy
to dewater. The perched groundwater could present an issue to excavations and placement of
foundations and for utility installation. It is our opinion that the contractor should be prepared for
dewatering.
It should be noted that groundwater readings are difficult to obtain in cohesive soils such as the lean clays
indicated in the boring logs. These soils have a low permeability and take a long period of time to obtain
groundwater readings in. If more accurate subsurface water levels are needed, we recommend
piezometers be installed to determine the groundwater level over several months. Monitoring of the

4. ENGINEERING ANALYSIS AND RECOMMENDATIONS
4.1 Discussion
Fills
No information was provided to us regarding density tests or excavation observations for the existing fills
encountered at the boring locations. The best option is complete removal of fills materials below all
pavements and utilities. However, these fills were likely placed during initial roadway or utility
construction and have been under traffic loading for many years. In our opinion, the risk of construction
of the pavement area or a utility upon these soils is generally low. The City may option for a partial
removal of the organic and wet fill materials.
The borings were completed in the roadway areas, however we used the boring data for the nearby
retaining walls. Fills should be removed entirely below the retaining wall foundation. These soils may be
suitable for reuse if they are free of organics and can be moisture conditioned to meet compaction
requirements.
Glacial Deposits
Based on the results of our borings, the glacially deposited soils generally appear capable of supporting
the retaining walls, pavement section, and utilities. However, some of the clayey or silty soils are locally
wet and would require a partial excavation and replacement.
General
It is our opinion that perched groundwater could be encountered by excavations at this site and could
affect construction of foundations and utilities. The contractor should be prepared for dewatering.
Generally, the soils in the upper 4 feet of the subgrade influence pavement performance the most. The
soils within the pavement subgrade consist of clays and silts, which are frost susceptible soils.
Consideration should be given to partially subcutting these soils an d replacing with a non-frost
susceptible granular fill to reduce the potential frost heave below the pavement section.
Silt soils are also not recommended for direct support of pavements for the aforementioned frost reasons
but also because they are sensitive to moisture changes, easily disturbed by construction traffic, and
difficult to compact. Where silt soils are present at the top of grading grade we expect a partial subcut
and replacement with an engineered fill is recommended.
4.2 Retaining Wall Area Preparation
We recommend removal of the fills and organics from below the retaining walls. Additionally, we
recommend a minimum of 1 foot of granular fill be placed directly below the retaining wall foundations for
support. If wet silt/clay soils that are loose/soft or become loose/soft are present under the 1 foot subcut
they should be subcut a minimum of another 1 foot.
Loosened sands at bottom of footing elevations should be surface compacted with a large vibratory roller
having a drum diameter of at least five feet (5’) and a static dead weight of at least ten (10) tons prior to
placement of engineered fill and backfill or concrete.
The sub-excavations should be oversized by at least one foot (1’) beyond the edge of footings for each
foot of depth below the bottom of footing elevations (1-horizontal to 1-vertical lateral oversizing). Because
the depth and lateral extent of the sub-excavations will vary away from our borings, we recommend a
qualified engineering technician working under the direction of a registered professional geotechnical
engineer observe and test the excavation bases during construction.
Based on the borings, it appears that the on-site non-organic soil can generally be reused as structural
backfill provided it is moisture conditioned and can be compacted to project specifications. However, silt
soils will be difficult to place and compact especially when wet and are not recommended as fill below the
retaining wall foundation or as backfill materials.
Geotechnical Report
2021 Street Improvements
Prior Lake, Minnesota
WSB Project No. 013977-000 Page 8
The site should be graded to prevent water from ponding on silty or clayey soils and potentially softening
them.
4.3 Foundation Recommendations
We recommend that the retaining wall foundations in this development be supported on conventional
spread footings bearing on a minimum of 1 foot of granular fill placed over naturally occurring glacial
deposits. Based on the borings, it is our opinion the footings throughout may be designed for a net
allowable soil bearing pressure not to exceed 2,000 pounds per square foot (psf).
Frost protection should follow Minnesota Administrative Rules 1305.1809. We recommend unheated
footings be placed at least five feet (5’) below adjacent exterior grade.
The factor of safety against shear or bearing capacity failure for this footing design would be three (3) or
greater. If the site is prepared as recommended, we estimate that total and differential se ttlements
corresponding to our assumed structural loads would be less than one inch (1”) and one -half inch (1/2”),
respectively, provided the bearing soils are not frozen or disturbed at the time of construction.
4.4 Excavations Near Existing Structures
The construction planned at this site will require some excavations near existing structures. We
recommend that the owner be involved with the contractor and engineer in determining what level of care
will be needed to ensure that there is no undermining of any existing foundation or slab and that no
sensitive equipment could be damaged by nearby construction. Monitoring of the excavation and existing
building can be completed with visual observations, vibration monitoring, crack monitoring, pr e and post
construction video surveys, and survey elevation points on the existing structure. At no time should the
excavations extend below existing footings or within a 1:1 oversize below the footings, unless that
foundation is properly braced and supported.
4.5 Retaining Walls
To help prevent water from accumulating behind retaining walls in clayey or silty soils, we recommend
drain tiles be placed at the base of the granular subbase. To promote water migration to the drain tile, we
recommend either a drainage composite be placed against the back side of the wall or at least two feet
(2’) (horizontally) of clean coarse sand be placed along the back of the wall. We recommend the upper
foot of backfill consist of clayey soils to act as a “cap” and reduce water infiltration into the backfill soils.
The drain tile should be connected to the storm sewer system or “daylighted” to suitable disposal areas.
To assist in below-grade/retaining wall design Table 4 presents estimated soil parameters for common
backfill soils. The coefficients presented below assume a level backfill at the top of wall. If the backfill is
sloped, these values may change significantly. Silt (ML) is not recommended as backfill for walls.

4.6 Backfill and Fill Selection and Compaction
The on-site non-organic soils may be reused as backfill and fill provided they are moisture conditioned
and can be compacted to their specified densities. Organic soils removed during the excavation process
should be limited to use as fills in landscaping areas. Wet soils that are excavated would need to be
dried before reuse as an engineered fill. Silt soils are not recommended for reuse below foundations,
utilities, or the pavement section and should be used only in landscaping areas. We recommend use of a
minimum of 2 feet of clean coarse sand with less than 50 percent passing the #40 sieve and less than 5
percent passing the #200 sieve when backfilling the bottom of a wet excavation.
Backfills with cobbles larger than six inches (6”) should not be placed within 3 feet of grading grade or the
retaining wall foundations or in contact with utilities. We recommend that clayey soils be moisture
conditioned to within +/-2 percent of the optimum moisture content as determined from their standard
Proctor tests (ASTM D-698). Fill should be spread in lifts of 8 to 12 inches, depending on the size and
type of compaction equipment used.
Table 5 provides the recommended compaction levels.

4.7 Pavement Subgrade Preparation and Stability
We recommend excavation of any organic fills within 3 feet of the bottom of the aggregate base or within
3 feet of the utility invert.
The soils at the bottom of the excavation should generally be prepared in accordance with MnDOT
Specification 2112, Subgrade Preparation. If the subgrade preparation operations encounter unstable
soils, we recommend removing these unsuitable materials and replacing them with Select Grading
Material (MnDOT 2105.1.A.6). If the on-site soils cannot be moisture conditioned and compacted as
recommended, additional measures, such as placement of additional sand subbase or a section of
coarse breaker run aggregate, can be completed to provide a firm base for subsequent fill placement.
Before placement of the sand subbase, the final subgrade should have proper stability within three
vertical feet of grading grade (grade which contacts the bottom of the aggregate base). This will generally
be achieved in fill areas with proper compaction of embankment materials and in cut areas through
proper subgrade preparation. The stability of the pavement subgrade should be evaluated prior to
placement of the sand subbase using the test roll procedure (MnDOT 2111), except a fully l oaded tandem
axle dump truck or a full water truck should be utilized for the proof roll. If unstable soils are found under
the test roll, these soils should be improved by means of scarification, moisture conditioning, and re -
compaction, or by subcutting and replacement.
We recommend placement of a geotextile fabric meeting the requirements of MnDOT Specification 3733,
Type V beneath the sand subbase and above the on-site silt soils to limit mixing of the granular materials
with the underlying fine-grained subgrade.

4.8 Pavement Area
Once the site has been prepared as recommended, we anticipate the prepared subgrade soils will consist
mostly of lean clays, sandy clays, clays with sand, and sands. Based on the MnDOT Flexible Pavement
Guide from 2017, the R-values of the subgrade soils would range between 10 and 70. We used a design
R-value of 10 for the roadways based on the predominance of the clay soils.
North Fish Point Road (North of Huron Road)
Information provided to us indicates that traffic along North Fish Point Road has an Annual Average Daily
Traffic (AADT) traffic volume of 1554. We estimated that traffic volumes would increase at an average
rate of 2.5%. Based on the traffic data provided to us, the traffic loading consists of 62% passenger
vehicles, 32% vans and pickups, 2% bus and truck traffic, and 4% tractor -trailers. Our design is based on
a standard twenty (20) year design life of the pavement section.
Based on the estimated traffic ADT we used the Minnesota State Aid Traffic Design forecast program to
calculate the roadway traffic to be equivalent to approximately 301,000 Equivalent Single Axle Loads
(ESAL’s) for roadway design. This is based on an Urban vehicle classification on a 2-lane road. Our
Minnesota State Aid Traffic Design forecasting was based on a 10-ton road design.
Based on MnDOT’s FlexPave excel design utilizing granular equivalent charts, we recommend the
pavement section indicated below in Table 6.

forecasting was based on a 10-ton road design.
Based on MnDOT’s FlexPave excel design utilizing granular equivalent charts, we recommend the
pavement section indicated below in Table 8.

General
We recommend limiting Recycled Asphalt Pavement (RAP) within the upper wear course to a maximum
of 10 percent in order to minimize cracking.
Aggregate base placement for pavement support should meet the gradation and quality requirements for
Class 5, 5Q, or 6 per MnDOT specification 3138. Aggregate base material should be compacted to 100
percent of its standard Proctor maximum dry density.
Within several years after initial paving, some thermal shrinkage cracks will develop. We recommend
routine maintenance be performed to improve pavement performance and increase pavement life.
Pavement should be sealed with a liquid bitumen sealer to retard water intrusion into the base course and
subgrade. Localized patch failures may also develop where trucks or buses turn on the pavement. When
these occur, they should be cut out and patch repaired.
The pavement sections above provide options to meet the ESAL requirements. Other pavement design
options would be acceptable as well as long as they meet the minimum requirements for bituminous
thickness, aggregate base thickness, and can meet the ESAL requirements.

2021 Street Improvements

WSB Project No. 013977-000 Page 12
4.9 Optional Frost Free Pavement Design
Optionally, the use of a non-frost susceptible sand cushion will help reduce the effects of frost heave. In
our opinion, placement of 12 inches of select granular fill below the Class 5 Aggregate Base should
generally provide for a non-frost susceptible subgrade. It should be noted that any sand cushion placed
below the pavement section will provide positive benefits for reduced potential frost heave. The owner
and/or design team should evaluate the costs and benefit of this option to determine if it should be
incorporated into the pavement design.
Drainage of the sand cushion is recommended. Drainage of the sand cushion may be accomplished by
daylighting to adjacent ditches or the use of drain tile. Drain tile wrapped in a sock should be placed at
the base of the sand cushion and tied into catch basins. We recommend the sand cushion contain a
select granular sand with less than 12% passing the #200 sieve. Alternately, a 3 inch minus rock fill could
be placed instead of a select granular sand and drain tile.
For transitioning the thickness of the sand subbase along the profile of the roadway, we recommend the
thickness have a longitudinal taper of no steeper than 10H:1V. A taper of 4H:1V can be used
perpendicular to the centerline for cross street/driveway connections. The placement of the sand
subbase should extend slightly beyond the outer edge of the curbs to maintain subgrade uniformity for
frost movement.
4.10 Utilities
Invert elevations for the sanitary sewer are anticipated to be within 15 to 25 feet below existing grades
and watermain would be approximately 8 to 10 feet below grade. Based on the borings, the subgrade
soils for the utilities will consist chiefly of lean clays with sand, sandy clay, silty sand, and sand.
We recommend removal of any organic soils of existing fills from within 3 feet below the utility invert. Any
wet silts/clays should be subcut a minimum of 2 feet and replaced with an engineered fill.
MnDOT Specification 3149.2F Granular Bedding should be placed to at least the crown of the pipe.
Trench backfill above this point may consist of the non-organic excavated soils once moisture conditioned
as recommended.
Underground utilities are expected to be installed by backhoes completing the excavations and placing
fills. Soil compactors should be used to compact the fill in even lifts to the specified densities.
4.11 Dewatering
Groundwater and wet or saturated soils were encountered in the borings. Perched groundwater could
enter the excavations. Dewatering can likely be accomplished with sumps and pumps placed at low
points in the utility trenches. Where granular soils are present, dewatering greater than 2 feet could
require sand point wells.
4.12 Construction Considerations
Good surface drainage should be maintained throughout the work so that the site is not vulnerable to
ponding during or after a rainfall. If water enters the excavations, it should be promptly removed prior to
further construction activities. Under no circumstances should fill or concrete be placed into standing
water.
Soil corrections at this site for foundations and pavement subgrades may not be continuous. We
recommend tapering the fills back to native soils at a ten to one (10:1) slope.
It is important to review the fill limits and total depth of fill when placing str uctures upon compacted
materials and when filling the excavation. The location of the footings should allow for at least a one to
one (1:1) slope from the bottom of the footing to the outside limits of the engineered fill.
Geotechnical Report
2021 Street Improvements
Prior Lake, Minnesota
WSB Project No. 013977-000 Page 13
It is important to check this at the time of construction that during filling, unsuitable soils do not encroach
within the one to one (1:1) slope limits and extending downward and outward from future footings.
4.13 Construction Safety
All excavations should comply with the requirements of OSHA 29 CFR, Part 1926, Subpart P
“Excavations and Trenches”. This document states that excavation safety is the responsibility of the
contractor. Reference to this OSHA requirement should be included in the job specifications.
The responsibility to provide safe working conditions on this site, for earthwork, building construction, or
any associated operations is solely that of the contractor. This responsibility is not borne in any manner
by WSB.
4.14 Cold Weather Construction
It is our understanding that construction is unlikely to occur during the winter months. However, if the
construction does continue into the winter months we recommend the following guidelines.
Roadbed embankments should not be constructed during periods when t he embankment material freezes
while being placed and compacted, nor should embankment material be placed on soil that is frozen to a
depth greater than 4 inches. When the soils are frozen to a depth exceeding 4 inches, at a time when
weather conditions are such that embankment construction could be continued without the material
freezing as it is being placed and compacted, the contractor may be permitted to excavate the frozen soil
and proceed with the embankment construction for so long as the weather w ill permit. The frozen soils
should be pulverized or replaced with other suitable soils to construct the embankments as specified.
Only unfrozen fill should be used.
Placement of fill and/or foundation concrete should not be permitted on frozen soil, and the bearing soils
under footings or under the floor slab should not be allowed to freeze after concrete is placed, because
excessive post-construction settlement could occur as the frozen soils thaw.
4.15 Field Observation and Testing
The soil conditions illustrated on the Logs of Test Borings in Appendix A are indicative of the conditions
only at the boring locations. For this reason, we recommend that excavations at this site be observed by
a soil engineer or technician prior to fill or backfill placement or construction of foundation elements to
determine if the soils are capable of supporting the fill backfill and/or foundation loads. These
observations are recommended to judge if the unsuitable materials have been removed from within the
planned construction area and an appropriate degree of lateral oversize has been provided.
WSB also recommends a representative number of field density tests be taken in engineered fill and
backfill placed to aid in judging its suitability. Fill placement and compaction should be monitored and
tested to determine that the resulting fill and backfill conforms to specified density, strength or
compressibility requirements. We recommend at least one compaction test for every 50 linear feet along
the retaining walls, and one compaction test for every 150 feet of utility trench at a vertical interval of two
(2) feet. Prior to use, proposed fill and backfill material should be submitted to the WSB laboratory for
testing to verify compliance with recommendations and project specifications.
Dynamic Cone Penetrometer (DCP) tests can be completed in the aggregate base in lieu of density
testing. We recommend following MnDOT Specification 2211.3.D.2.c.
WSB would be pleased to provide the advised field observation, monitoring and testing services during
construction.
4.16 Plan Review and Remarks
The observations, recommendations and conclusions described in this report are based primarily on
information provided to WSB, obtained from our subsurface exploration, our experience, several
assumptions and the scopes of service developed for this project and are for the sole use of our client.

We recommend that WSB be retained to perform a review of final design drawing and specifications to
evaluate that the geotechnical engineering report has not been misinterpreted. Should there be changes
in the design or location of the structures related to this project or if there are uncertainties in the report
we should be notified. We would be pleased to review project changes and modify the recommendations
in this report or provide clarification in writing.
The entire report should be kept together; for example, boring logs should not be removed and placed in
the specifications separately.
The boring logs and related information included in this report are indicators of the subsurface conditions
only at the specific locations indicated on the Soil Boring Exhibit and times noted on the Logs of Test
Boring sheets in Appendix A. The subsurface conditions, including groundwater levels, at other
locations on the site may differ significantly from conditions that existed at the time of sampling and at the
boring locations.
The test borings were completed by WSB solely to obtain indications of subsurface conditions as part of a
geotechnical exploration program. No services were performed to evaluate subsurface environmental
conditions.
WSB has not performed observations, investigations, explorations, studies or testing that are not
specifically listed in the scope of service. WSB should not be liable for failing to discover any condition
whose discovery required the performance of services not authorized by the Agreement .

Meeting Summaries
15453 Fish Point Rd SE (John Whitmore)
- The residents’ primary concern is the work occurring along Timber Trail SE (north of their
property), since the street is quite a bit higher in elevation than their lot. There are City-
owned timber retaining walls (built around 1984) that are beginning to degrade at the
north property line, and private landscape block retaining walls. They are requesting that
the walls are replaced at the City’s cost. City and WSB staff indicated that attempts will
be made to locate property corners and verify that the timber wall is within the road right-
of-way.
- There is an existing storm sewer grate/inlet at the base of the landscape block wall that
appears to connect to the storm sewer in the street via an 18” RCP pipe. The residents
indicated that when that was first installed it would backup in major storms and had
flooded their basement. The City completed some adjustments many years ago, and it
hasn’t been as much of an issue since. WSB will incorporate this storm sewer inlet into
the site analysis.
- It was also discussed that all of the shrubs along the top of the wall were in very close
proximity to the road and would likely need to be removed. The residents stated they
were fine with that, but also stated that their goal is to “screen” the sight an d noise of
traffic along the street and along TH 13.
- It was noted that their services are off of Fish Point Road and on preliminary review, their
replacement didn’t seem to require any tree removals in their front yard.
- The landscaping and trees at the northwest corner of their property will likely need to be
removed and the residents stated they were fine with that.
5910 Glory Circle SE (Michael Autenrieth) & 5901 Glory Circle SE (Kory Mosher)
- This was a joint meeting with both residents. One main question/concern was if the
watermain and sanitary sewer between their two properties is going to be replaced. Both
of their services come from the side yard mains within the easement. The water service
for 5910 was located, and an attempt was made to locate 5901.
- The resident at 5910 Glory Circle SE indicated that during major rain events, about every
5-6 years, there is a ravine behind 5900 that essentially floods and runs between the two
houses and into the storm sewer inlet in the cul-de-sac. He stated that the house at 5900
has flooded many times. City and WSB staff investigated along Timber Trail SE and
determined that it is likely all the drainage is coming from the area outside of City ROW
and from rear yards and roof tops. This, however, will be evaluated with the stormwater
analysis.
- The resident at 5901 asked how much of their driveway would be impacted and if their
pine tree in the boulevard would be impacted and replaced if impacted. Nick M. stated
that the tree will likely be affected, and if it is in the ROW it won’t be replaced, but if it is
K:\013977-000\Admin\Meeting\8 5 20 Phase 1 Property Owner Meetings\Property Owner Meeting Summary.docx
on private property, it will. He also gave the resident an approximate location of driveway
removals.
5910 Miller’s Circle SE (Jody Stroh)
- The resident’s main question was regarding the large timber retaining walls that abut the
street on the west side of her property and continue up her driveway toward her garage.
It was determined that her sewer and water service are underneath the portion of the wall
adjacent to the driveway and that they would be impacted. It was discussed that final
wall replacement details will come with design, but that it is likely the project will only
replace the portion of the wall impacted by utility work and that the property owner would
be responsible for replacing any other portion of the wall if they do desired. She asked
how that coordination would work and Andy B. stated that the logistics will be more
thought out as we get into design and it will be communicated back to the property
owners.
- It was also noted to the resident that the two large trees in her front yard will likely be
impacted by the sewer and water service replacement. Andy B. explained that there may
be a chance that they could be saved during the replacement but may die in a few years
if the root system is impacted. He discussed there may be a benefit to having the cost of
the tree removal be covered by the project as opposed to the resident later on.
- The resident indicated that she would like to keep the retaining wall on the east side of
her property if at all possible.
5833 Timber Trail SE (Robert Dudzik)
- The resident’s main concern was what impacts are proposed to the timber retaining
walls. He indicated that he built the walls and would like to keep them in place if
possible. The City and WSB investigated as to the location of the sewer and water
service and noted that the water service was in the driveway, about 8’ from the edge of
the retaining wall. The resident recalled that the sewer service comes out of the hose on
the west side of the property but then angles towards the driveway and runs adjacent to
the water service. City and WSB staff will review sewer televising tapes for the area to
better determine where this service comes into the main.
- The resident also asked what sort of access there will be to his property, as he is
currently experiencing mobility challenges. The response was that WSB and City staff
will work to communicate access needs to the contractor and require that special
accommodations be made to provide access. In general, access to the driveway will be
maintained at the beginning and end of each working day for vehicles, except when the
concrete curb is curing for 5 days in front of the driveway.
15654 Omega Trail SE (Christopher Wickstrum)
- This resident was joined by his neighbor to the east at 15659 Omega Trail SE. One
question/concern raised by these residents was how the project will address the improper
drainage of the cul-de-sac. They noted that water pools at the end of their driveways and
does not make its way down the street to the north. They were curious if improvements
to the street could help reduce the slope of their driveways as well. Staff relayed that this
drainage issue would be addressed with the storm sewer and street design, and that
there is a chance that the cul-de-sac can be raised slightly to help with the steep
driveways.
- They asked if the private utility pedestals could be moved and/or consolidated with the
project. Staff relayed that the City and WSB coordinate with private utilities but that there
are typically no restrictions or requirements to move existing pedestals. The City and
WSB will notify the private utilities of the residents ’ request.
K:\013977-000\Admin\Meeting\8 5 20 Phase 1 Property Owner Meetings\Property Owner Meeting Summary.docx
- It was also request that Public Works staff review how snow is stored in the cul-de-sac,
as currently they pile it up on the property at 15654 and cover up an electrical transformer
and cable pedestals.
- The resident at 15654 indicated that they would like to widen their driveway to 24’ wide.
Nick M. said that this resident should coordinate with the field staff when curb and gutter
is being installed.
- Lastly, they requested that the design consider an addition of a cross walk at Fish Point
Road and Omega Trail. They have children that are too close to the school to bus, but
don’t feel safe crossing the road to get on the sidewalk along the east side of Fish Point
Road. The City said that internal discussions are being had about this issue and the
design will consider a crossing, or extension of the sidewalk on the west side, so that the
crossing at TH 13 can be added and utilized.
15489 Omega Trail SE (Dianna & Greg Running)
- The resident’s primary concern was a drainage issue in their yard were water is being
held since the street is higher than their yard. This low area somewhat drains to an
existing plastic pipe that goes under their driveway and connects to the storm sewer
catch basin in the roadway. They were told that storm sewer will be extended into their
yard and a catch basin will be installed to collect the drainage and bring it into a new RCP
pipe underneath the curb line in their street. The project will also rem ove the existing
plastic pipe and replace their heaved concrete apron.
- They indicated that they would like to keep the large oak tree to the left of their driveway
but were told it is likely that with the storm sewer replacement this tree would have to b e
removed. They indicated that would be alright, if it’s necessary. They also stated all the
shrubs along the street are ok to be removed.
15480 Omega Trail SE (Kelly Flanagan)
- The resident was not home at the meeting time of 3:30 pm. She was contact ed by
Kirsten Gray, but wasn’t going to be home until 5:00 pm when the meetings were
wrapping up. She was told that the City and WSB would reschedule a meeting.
5925 Hidden Oaks Cir (Judy Olson)
- The resident’s primary concern was their newly constructed concrete driveway and
whether or not it would be impacted. It was pointed out to the resident that the curbs stop
is along the edge of the driveway, and the replacement of the water service and sanitary
sewer service would impact the driveway. They were told the driveway would be
replaced in-kind, at full width, and that an attempt would be made to match the sawcut
joint type.
- They were also notified that the pipe tree would need to be removed, and they were fine
with that and asked if they could keep the wood for firewood. They were told they could
keep the wood and that they should communicate that with the field staff during tree
removals.
