Pete Young, Water Resources Engineer
From: Kris Keller, Laura Kivisto, Dustin Simonson, Chuck Rickert - WSB
Date: July 5, 2021
Re: Villas at Crest Woods
WSB Project No. 10704-000
We have completed our preliminary plat review of the civil and stormwater plans submitted for the
Villas at Crest Woods on June 15, 2021 as prepared by Civil Site Group. The following
documents were received:
· Preliminary Plat Plans (VILLAS AT CREST WOODS-CITY RESUBMITTAL 6-15-21.pdf)
· Preliminary Plat (20302-NHH Prior Lake-PRELIMINARY PLAT-Pre Plat-Combined-6-14-
2021.pdf)
· Stormwater Report (00 - CSG Villas at Crest Woods 20302 STORMWATER REPORT -
3-15-2021.pdf)
· Geotechnical Evaluation Report (Geotechnical Evaluation Report - Summit Preserve
Continuation, B1908052.pdf)
· Trip Generation Study (Trip Generation 3-14-21 Prior Lake.doc)
· Alta Survey (ALTA Chadwick (Summit Preserve) 8-13-2019.pdf)
· Boundary Topographic Survey (20302-NHH-Prior Lake-3-19-2021.pdf)
Comments are provided within this Memorandum and in the corresponding redlined plan set.
Please note that not all comments within the plan set are in the Memorandum. We have the
following comments with regards to engineering and stormwater management. Greyed out
comments have been addressed. Red comments are new to this review. Comments in standard
text still apply.
General
1. Submit for and provide copies to the City of all required permits from regulatory agencies
(MCES, Minnesota Pollution Control Agency, Minnesota Department of Health, County,
etc.)
2. An NPDES permit is required as the site exceeds 1 acre of disturbance.
3. Provide a memo along with your plan revisions which responds to the provided
comments.
Plat
1. Revise Block 6 lots to meet City R-1 size requirements
2. Provide drainage and utility easements for all drainage swales that convey water from
one lot across another
Villas at Crest Woods
July 9, 2021
Page 2
a. The width of the easement should be a minimum of 10’ with at least 5' on either
side of the center of the swale
3. Please note which Outlots will be dedicated to the City and which will be privately owned.
a. Extend lot lines to remove all outlots other than Outlot F which will be deeded to
the City
b. Provide drainage and utility easements over all public utilities and stormwater
management facilities on private property.
4. Provide drainage and utility easements for all public utilities running across private
property.
a. The width of the easement should be at least two times the greatest depth of the
utility with a minimum of 20' centered on the utility
5. Remove the three Block 7 lots along 138th Street. The lots for Block 7 are dangerously
close to the turn lane tapers and the intersection with 138th St and Crest Ave. This would
be exasperated with reverse movements coming out from the driveways. The traffic
engineer recommends removing them from the segment altogether.
Streets/Trails
1. Based on the proposed site plan the anticipated traffic generation would be 651 vehicle
per day (vpd), 52 AM peak hour trips and 69 PM peak hour trips, assuming 69 single
family lots on the site. This is consistent with the Trip Generation memorandum provided
by Swing Traffic Solutions (March 14, 2021).
2. Access for the site is proposed using the extension of 138th Street (east/west) and
Johnson Street (north/south). Johnson Street is a proposed local city street and 138th
Street is a proposed Major Collector roadway in the City’s 2040 Comprehensive Plan.
The design included on the site plan conforms to a local street standards (66ft ROW, 32ft
width) and Collector Street standards (66ft ROW, 36ft wide).
3. 138th Street provides access to the regional transportation system at Crest Avenue
(CSAH 18). Crest Avenue (CSAH 18) is a Scott County roadway classified as an A-Minor
Arterial Expander in the County’s 2040 Transportation Plan, however it has been
identified as a potential turnback to the City and reclassification as a Collector roadway.
The existing ADT is 5600vpd and projected in 2040 at 10,700vpd.
4. The proposed site plan shows improvements at the Crest Avenue (CSAH 18) and 138th
Street intersection of adding a southbound left turn land and northbound right turn lane.
The design of these improvements will need to be coordinated with Scott County
including the required length of the turn lane bay and the width of the turn lanes.
Typically, the turn lane length is 250ft to 300ft and the width is 13ft to 14ft to the face of
curb. Include a typical section for the Crest Avenue (CSAH 18) improvements.
5. 138th Street at Crest Avenue (CSAH 18) is proposed to be widened to include four lanes,
westbound approaching Crest Avenue (CSAH 18) with a right, through and left and
eastbound exiting one through lane. The plan shows the lanes adjacent to the curb at a
width of 12ft to back of curb. At a minimum these widths should be 12ft to the face of curb
or 13ft to back of curb. The taper to the turn lanes should be a minimum of 10:1. A typical
section should be provided for the 138th Street Improvements (Collector Street).
6. A truck turning template should be provided showing the turning movements from Crest
Avenue (CSAH 18) to 138th Street. The eastbound exiting lane appears to be too narrow
Villas at Crest Woods
July 9, 2021
Page 3
to accommodate these movements. An exhibit should be provided showing the turning
radii.
7. The side street approaches to 138th Street should have stop sign control.
8. A sight line analysis should be completed for all intersections including the intersections
on 138th Street at Johnson Street and Street at Street A, and on Johnson Street at Street
B, Street C, Meridian Way and Apex Way.
9. The final plans should include a signing and pavement marking plan, including at a
minimum: size and locations of stop signs, street signs and pedestrian crossing signs,
and size type and location of street lane markings and pedestrian crossing striping.
10. Revise cul de sac for Street A to meet City standards for offset spacing (660’) from
collectors or higher order streets.
11. Revise 138th St intersection with Crest Ave (CR 18) to match exhibits sent to developer.
12. Flip the driveways from Lot 1 Block 10 and Lot 1 Block 11 away from the intersection.
13. Street Profiles
a. Provide street profiles that show the proposed street grades and vertical curves.
b. Identify centerlines of connecting streets at intersections in profile views.
c. Vertical curves need to meet the minimum required K value (30 for crest curves,
36 for sag curves) for 30 mph.
14. Provide horizontal curve/alignment information for all roads.
a. Curves must meet a 30 MPH design speed and shall have a minimum 250’
centerline radius
15. Provide typical sections for all roads
a. Include proposed curb types
b. Include supporting geotechnical information
Stormwater Management
1. Drainage Areas and Modeling
a. Verify that there is no stormwater runoff onto the site from the development on
the south boundary of the site.
b. Label the wetlands and BMPs on the drainage area maps.
c. Calculate the time of concentration values in lieu of using a generic value.
d. Ensure drainage areas in HydroCAD match the drainage area maps (EX2A).
e. Proposed Conditions HydroCAD Model
i. Modify the primary outlet from Wetland 2 to match the plans.
ii. Modify the EOF elevations in HydroCAD match the elevations on the
plans.
iii. Add a starting elevation to BMP 1 at the infiltration elevation. Do not
include dead storage in the model.
Villas at Crest Woods
July 9, 2021
Page 4
iv. BMP 2 includes a starting elevation at 998, but infiltration starts at 996
according to the plan set. Modify the model to match the plans.
v. Modify the primary outlet from BMP 2 to match the plans.
f. Update all HWLs listed on the plans to match HydroCAD.
2. Rate Control
a. Because the property is within the Stormwater Management Overlay District #1,
prescriptive rate control of 0.25 cfs/net acre discharge from the site is the
maximum allowable discharge for all storm events. Please provide an analysis
showing that the site meets this requirement.
i. Verify that the existing County storm system elevations will allow for
redirecting the proposed pond/infiltration area in the southwest corner to
the existing County/City storm system to the south.
1. This will allow for the removal of the long run of storm sewer
leading out of Wetland 3 to the north.
2. Adjust rate control to maintain sufficient capacity in the existing
system particularly at the storm sewer structure on the southeast
corner of Crest Ave and 140th Street.
b. Please provide an analysis without available wetland storage to determine if
wetland storage is used to meet rate control requirements. If wetlands are used
for rate control, show that the wetlands are eligible based on the requirements of
Section Six in the Public Works Design Manual.
i. If wetlands are used to meet rate control, include columns specifying the
tributary area, the required discharge rate (0.05 cfs per tributary acre in
the 2-year event, 0.15 cfs per tributary acre in the 10-year event, and
existing peak flow for the 100-year event), and the wetland discharge
rate in the proposed rate control table for each wetland.
3. Volume Control
a. Calculations can be modified to consider 1-inch of runoff from the new
impervious surface in lieu of 1.1-inch to meet Prior Lake requirements.
b. Routing impervious to BMPs to maximum extent possible. Preliminarily met;
consider soil boring comments below.
4. Water Quality
a. Preliminarily met; consider soil boring comments below.
5. HWL and EOF requirements
a. Low floor elevations shall be at least 2-feet above the HWL.
i. Homes near Wetland 2 and Wetland 3 do not meet this requirement.
b. Low opening elevations shall be at least 2 feet above the EOF.
i. Homes near Wetland 2 and a home near Wetland 3 do not meet this
requirement.
6. BMPs
a. Please provide a cross section detail of the BMPs.
Villas at Crest Woods
July 9, 2021
Page 5
b. Soil boring ST-10 shows clay down to 7-feet below the existing surface. Verify
that the infiltration BMP 1 will function in this location by including provisions for
at least 2 infiltration tests in all proposed infiltration basin locations. In the same
manner, provide soil borings at the location of BMP 1. As such, justify the use of
a 0.8 in/hr infiltration rate.
c. Overlay the tree removals plan on the grading plan to verify that all trees and
brush below the controlled water level of the BMPs will be removed.
d. Specify maintenance access routes to the BMPs (maximum of 8% grade,
maximum of 2% cross slope, and minimum of 10-feet wide).
e. Provide Walker Method calculations for appropriate sizing of the permanent pool
volume.
f. A 10-foot wide aquatic bench is required below the NWL of the pond.
g. The invert elevations of pond inlet flared end sections shall match the outlet
elevation of the ponds.
h. The EOF of a pond should be at least 1 foot higher than the HWL.
7. General
a. Clean up the plans so labels do not overlap (particularly the basin names and
HWL information).
Grading
1. Minimum grading for drainage swales and lot grading shall be 2%.
2. Add the following notes to the grading plan:
a. Perimeter/downstream sediment control BMPs shall be installed by the
contractor and inspected by the City prior to any site work.
b. Slopes greater than or equal to 3:1 shall have approved erosion control BMPs
installed immediately after finished grading.
3. Call out the wetland buffer on the grading plan.
4. Show house style detail.
5. Label the driveway grades.
6. Some proposed house elevations do not appear to match adjacent proposed contours
(Block 3, etc.)
7. Several blocks have drainage that is directed at the proposed building pads. Revise
proposed contours and provide spot elevations between all lots to show drainage
directed away from proposed building pads
8. Provide EOF’s for all low points in the streets and greenspaces.
9. Several areas around the perimeter of the development have greater than 3:1 slopes
matching with the adjacent existing grades. There is a maximum of 4:1 slopes in
maintained areas.
10. Show easements on grading plans
a. Provide drainage and utility easements for all drainage swales that convey water
from one lot across another
11. Label all streets.
Villas at Crest Woods
July 9, 2021

lots to the development in order to best match grades at the development limits.
13. Show storm sewer on grading plans
a. Provide all inlet elevations
14. Shift the driveway access for Lot 3 Block 10 from Meridian Way to Lupine Trail.
15. Shift the hydrant out of the driveway for Lot 8 Block 1.
16. Provide additional hydrants along 138th Street east of Jackson Street to maintain fire
protection and maximum allowed 450’ spacing.
17. Remove and install the hydrant in the Lupine Trail temporary cul de sac behind the
revised back of curb.

additional drainage (PR13).
c. Storm sewer pipe size and grade shall be greater than or equal to 15-inches in
diameter and 0.5% slope.
d. Either show the proposed storm sewer on the grading plan (as a background
layer) or show the grading on the utility plan to verify that catch basins are
included at low points and placed appropriately.
e. The maximum spacing between storms sewer structures is 400-feet. Adjust
structure spacing to meet requirement.
f. Provide the MnDOT standard rip rap detail for the rip rap at the storm sewer

3. Watermain
a. All water fittings should be labeled as to size and type such as bends, tees,
plugs, etc.
b. The location, size, type, and class of all water services shall be noted on the
plans.
c. Developers are responsible for constructing the services to the easement line
which is approximately 10’ beyond the right of way line.
d. Provide a minimum of 18” vertical separation for all watermain crossings with
sanitary and storm sewer. Also, other utilities that cross the watermain shall
cross at a 90 degree angle, if possible, with the minimum requirement of a 45
degree angle for the crossing. Provide insulation for all storm sewer crossings.
e. Show on plans the existing and proposed watermain in plan and profile view
along with other existing and proposed utilities in the construction zone.
f. Shift the gate valve from the western leg of the intersection of 138th Street and

c. Label all streets
Miscellaneous
1. Utilize current City of Prior Lake Design Manual and Standard Detail Plates
2. Include City Plate #402 for Sanitary Sewer Outside Drop Manhole
SWPPP
1. Specify the locations of the temporary sediment basins on the ESC plan, required for all
drainage areas greater than 5 acres.
2. Update the SWPPP to be specific to the site including the description of the construction
activity, impervious surface, contact information, party responsible for long term
maintenance of the system, etc. The current SWPPP appears to be for a different project.
3. Call out inlet protection on all catch basins (CBMH 16A, CBMH 16B).
Wetland
1. The development is showing wetland impacts through the removal of smaller wetlands
within the site. Wetland impacts will need to be approved under WCA.
a. The application for WCA permit has not been submitted to the City for Review.
2. The following applies to the required wetland buffers:
a. The site falls within Prior Lake Spring Lake Watershed District. For this site, all
wetlands must have minimum buffer width of 20 feet with an average width of 30
feet wide from the delineated wetland edge. No grading is allowed within wetland
buffers, with exceptions for pipe outlets and associated riprap, reseeding and soil
amendments, grade changes adjacent to approved WCA impacts, and temporary
impacts associated with utility installation.
b. Change the name of the “Buffer” line to “Wetland Buffer” on all plan sheets to
avoid confusion.
c. Show a double row of silt fence upgradient of all wetland buffer lines. This is also
a requirement of the NPDES general permit.
d. Buffers shall be identified within each parcel by permanent monumentation.
Monuments shall be required at each parcel line where it crosses a buffer and
shall have a maximum spacing of 200 feet along the edge of the buffer.
Additional monuments shall be placed as necessary to accurately define the
edge of the buffer.

PLSLWD
Rule D – Stormwater Management
1. HydroCAD Modeling Comments
a. Runoff should be calculated separately for pervious and impervious areas,
instead of using a weighted curve number for each subcatchment.
b. Time of concentration should be modeled explicitly for each subcatchment
instead of assuming 10 minutes for all subcatchments.
c. Entire site is modeled as 75% grass cover in good condition. However, aerial
imagery indicates that landcover is largely wooded, which should be modeled
with a lower curve number for existing conditions.
d. Web soil survey indicates a portion of the site with HSG B soils, which is similarly
reflected in soil boring #6. This portion of the site should be modeled as HSG B
instead of HSG D. Under proposed conditions, this area should be modeled as
HSG C to reflect compaction of soils due to construction.
e. Documentation should be provided for the existing infiltration basin to confirm
that 0.63 in/hr is an appropriate infiltration rate.
f. The overflow elevation for Wetland 1 is not accurate. 2-foot contours indicate the
overflow to be between 1018 and 1020, but it is modeled at 1015.4. Other
wetland overflows were not checked but should be reviewed for consistency.
2. Two infiltration basins are proposed, and each are designed with an infiltration rate of 0.8
in/hr. Given HSG D soils on site this is not an appropriate infiltration rate and basins are
likely to retain water for longer than 48 hours. Further assessment of infiltration feasibility
is highly recommended. It is also recommended that basins be designed with drain tile
lines and a gate valve. This allows for dewatering of the basin for maintenance and to aid
vegetation establishment.
3. No pretreatment has been provided for runoff that is piped to the infiltration basins. This
will lead to accumulation of sediment within the basins which is detrimental to infiltration
capacity. Storm sewer profiles were not provided so it is unclear if sump manholes are
provided prior to storm sewer discharge.
4. Further review of changes to site drainage are warranted. Under existing conditions
Wetlands 1 and 2 drain east to Crownline Drive. Under proposed conditions these
wetlands will be directed west towards the other onsite wetlands.
5. The proposed project does not meet runoff rate requirements. Total runoff rate from the
site increases for both the 2 and 10-year, 24-hour storms.
6. Significant portions of the site (PR2, PR3A, PR5, PR8, PR9, PR10, PR11) are routed
directly to existing wetlands with no stormwater management. Further, PR10 appears to
include much of the roadway which is directed by storm sewer to infiltration basin 1, not
Wetland 1 as routed in the HydroCAD model. Other routing was not checked and
warrants further review.
7. Subcatchments PR6 and PR6A are routed to an existing infiltration basin. Has this
infiltration basin been reviewed to confirm it has additional capacity for the proposed
runoff?
8. Documentation of required NPDES permit has not been provided.
Villas at Crest Woods
July 9, 2021
Page 10
Rule E – Erosion and Sediment Control
1. Construction sequencing notes have not been provided. These notes should clarify the
timing of infiltration basin construction and whether these facilities will be used as
temporary sediment basins or protected from construction sediment to allow vegetation to
establish. A detail was provided for temporary sediment basins, but basins were not
located in the plans.
2. Perimeter control (silt fence) is needed around Wetlands 4 and 7.
3. Has approval been received for proposed land disturbance outside of the site boundary?
Rule G – Wetland Alterations
1. Provide documentation regarding the status of WCA approval for proposed wetland
impacts.
2. Provide documentation that a wetland replacement plan has been reviewed and
approved by the city of Prior Lake.
Rule J – Buffer Strips
1. The overall site plan appears to indicate wetland buffers around unfilled wetlands.
However, buffer boundaries have not been clearly market. Wetland buffers should be
established and maintained a minimum distance of at least 20 feet and 30-ft average
from the wetland edge. Buffers should be maintained with healthy native vegetation and
documented by signage located at the upland edge of the buffer.
2. The developer will be required to enter into a Development Agreement and provide
Conservation Easements to the District over the wetlands and required buffer strips. If
proposed revisions to PLSLWD Rules are adopted prior to development, buffer widths
may need further adjusted (expanded) based on Wetland Categorization.

Memo
The Community Development Department has reviewed the Preliminary Plat and PUD plans for
the subject project with a plan date of 8-18-21 and we have the following comments.
General
1. Development Fees – The following development fees are to be collected prior to
recording of any approved 2021 final plat application: Park Dedication of 61 lots at
$3,750 per lot, Trunk Water ($3,840/net acre), Trunk Sanitary Sewer ($4,700/net acre),
Trunk Storm Sewer ($4,160/net acre), and a 6% administrative fee and 8% construction
observation fee based on the total estimated construction costs (which include
landscaping, streets, public trails, and public utilities).
2. The City Council will need to weigh the modifications (lot size and setbacks) requested
