Report and Authorize Preparation of Plans & Specifications
Background
The City is currently working with Summergate Companies on a 421-lot development known
as Summers Landing. This development is located along the west side of Hadley Avenue,
north of 95th Street and south of 90th Street, and is proposed to be completed in six phases.
The first three phases of the development were completed in 2016, 2018, and 2019. The
phases included 55, 91, and 75 single family lots, respectively, and publicly constructed infra-
structure through the 429 assessment process. The developer has petitioned the City to com-
plete the utility and street construction for the fourth phase as a City project through the 429
process as well.
On February 5, 2020, the City Council authorized the preparation of a feasibility report for the
Summers Landing 4th Addition.
Discussion
Feasibility Report
On the basis of the Council’s previous action, a feasibility report has been prepared. Upon this
analysis, the project is felt to be physically and financially feasible. The feasibility report is en-
closed for the Council’s review.
Summary of Infrastructure Improvements
The Summers Landing 4th Addition Street & Utility Improvements project includes the con-
struction of all public improvements within Summers Landing 4th Addition. This will include the
extension of 8-inch and 10-inch sanitary sewers and 8-inch and 18-inch water mains through-
out the development to serve all 122 lots. The sanitary sewer will connect into existing infra-
structure within the existing Summers Landing Development. The water main will also connect
into existing infrastructure within the Summers Landing Development. The 18-inch water main
is being installed along 91stStreet and will connect with the existing main on Mississippi
Dunes Boulevard. Per the City’s policy, the cost to upsize above 8-inch water main is reim-
bursed through the Water Area Fund. Concrete storm sewer pipe will be installed throughout
the 4th Addition to collect stormwater and route it to the stormwater ponds within the City
outlots.

The City standard residential 28-foot F-F road section will be constructed throughout the 4th
Addition, which will consist of 3.5 inches of bituminous over 8 inches of aggregate base. Ini-
tially, only the first 2-inch lift of bituminous will be placed, along with a bituminous wedge to
protect the concrete curb and gutter. The bituminous wedge will be removed and the final 1.5-
inch lift of bituminous will be placed during a final streets project when 90 percent of the homes
are constructed or after three years. Residential streetlights with LED luminaries will be
installed throughout the 4th Addition. Concrete sidewalk will also be installed within the devel-
opment.
Mass site grading for this phase is anticipated to start in late March, with utility and street con-
struction beginning in June of 2020.
Recommendation
It is recommended that the City Council adopt a resolution approving the feasibility report and
authorizing the preparation of plans and specifications for the Summers Landing 4th Addition
Street & Utility Improvements.

PROJECT SUMMARY
INTRODUCTION
The City is currently working with Summergate Companies on developing the Summers Landing 4th Addition. The
development is located on the west sides of Mississippi Dunes Boulevard, adjacent to the Summers Landing 2nd and 3rd
Additions (see figure 4 in the Appendix of this Report). Like the first three phases of this development the Developer has
petitioned the City to complete the Summers Landing 4th Addition Street and Utility Improvements through the Chapter
429 process with construction starting in 2020.
This Report will address the proposed utility and street improvements for the Summers Landing 4th Addition. Summergate
Companies proposes to construct 122 single family lots. Each of the lots will receive City sanitary, water, and street
improvements.
PROJECT SCOPE
This project consists of utility and street improvements in the general location shown in Figure 1:
Figure 1 Ï General Project Location
th
Summers Landing 4 Addition Street and Utility Improvements 2
Required Improvements
This project includes the construction of public sanitary sewer, water main, storm sewer, and public streets to service the
proposed development. The proposed utility layout for the Summers Landing 4th Addition is shown on Figure 2 in the
appendix of this Report. Sanitary sewer, water main, storm sewer, and street improvements are proposed for all lots in the
Summers Landing 4th Addition development.
S ANITARY S EWER
The sanitary sewer for Summers Landing 4th Addition will be served from the existing ten-inch sanitary sewer located on
the west end of 91st Street South, the existing ten-inch sanitary sewer located on the west end of 92nd Street South, and
the existing ten-inch sanitary sewer located on the west end of 93rd Street South. The sanitary sewer was installed in 2019
as part of the Summers Landing 3rd Addition Project. Figure 2 in the Appendix of this Report shows the proposed sanitary
sewer extension through the Summers Landing 4th Addition. The sanitary sewer lines within the Summers Landing 4th
Addition will be eight inches or ten inches in diameter and will be extended to the west edges of the plat to help serve
future development phases.
W ATER M AIN
Ductile iron water main will be installed throughout the development and will be between eight inches and eighteen
inches in diameter. The proposed Summers Landing 4th Addition water main will connect to the existing eighteen inch
water main located in 91st Street South just west of Mississippi Dunes Boulevard, the eight inch water main located in
92nd Street South west of Mississippi Dunes Boulevard, and the eight inch water main located in 93rd Street South west of
Mississippi Dunes Boulevard.
As part of the public improvements, eighteen-inch trunk water main will be installed. A water main oversizing credit will
be provided to the Developer for water main trunk improvements installed within the development.
Water services will be provided for the islands to allow for irrigation.
S TORM S EWER
The Summers Landing 4th Addition will include the installation of public storm sewer for the development and will include
the construction of a new storm water pond and infiltration area in the middle of the development to collect and treat
runoff from the site. Treated storm water will then be directed southwest through the proposed park area within the
development.
S TREETS AND S IDEWALK/P ATHWAYS
The accesses to the 4th Addition will be from 91st Street South, 92 Street South, and 93rd Street South. Future connections
to the west ends of 91st Street South and 93rd Street South are anticipated.
This Report proposes to install permanent curb and gutter and place the first lift of bituminous for all streets. A bituminous
wedge will be placed to protect the curb and gutter until the final lift of bituminous is placed. The cost for the final lift of
bituminous has been included in this Report. It is estimated that the final lift of bituminous would be installed
approximately three years after the bituminous base lift has been placed or when at least 90 percent of the homes are
constructed.
Common Excavation for the streets was not included in this Report because it is assumed that the DeveloperÔs grading
contractor will be completing this task. If this work is not done prior to the street and utility work, there would be
additional costs added for the common excavation of the street areas.
th
Summers Landing 4 Addition Street and Utility Improvements 3
Figure 3 in the Appendix of this Report shows the proposed development sidewalks and trails that will be constructed as
part of this project.
As part of the Hadley Avenue Reconstruction Project in 2016 trails were installed along the west side of Hadley Avenue
adjoining the development. A portion of the costs for the Hadley Avenue trails, based on the number of lots constructed,
are being assessed during each phase of the development.
The Developer was responsible for the costs associated with constructing the Hadley Avenue turn lanes adjacent to the
development, a portion of the Hadley Avenue construction costs from 90th Street to 95th Street, a portion of the 95th
Street construction costs from Hadley Avenue to Mississippi Dunes Boulevard and a portion of the roundabout costs at
95th Street and Hadley Avenue. These improvements that were constructed as part of the Hadley Avenue
Reconstruction project in 2016 are being assessed with each phase of the development.
Required Easements
All public utilities will be located under the public street right-of-way and within dedicated utility easements.
Required Permits
This project requires the following permits:
MPCA General Storm Water Permit (NPDES Permit).
MPCA Sanitary Sewer Extension Permit.
MN Department of Health Water Main Permit.
