ATTAC�NTS: Feasibility Report, Resolution APPROVED BY:
At the April 4, 1994 Council meeting, the Carrollton 4th drainage
concerns were discussed in regards to possible solutions for a
possible flooding scenario in the Carrollton 4th Addition. At that
time, staff recommended that an additional outlet pipe be constructed
southerly out of the 4th addition to the O'Learys pond area south of
CSAH 42 . Staff recommended that council authorize the preparation of
a feasibility report to further address the costs and funding sources
for that outlet pipe.
The attached feasibility report outlines the details of construction
of this outlet pipe. As stated, an 1800 ft, 21 inch storm drain would
be constructed to provide both a second outlet to the Carrollton 4th
Addition plus an outlet for the Edwin Rahn Addition Pond and the
entire drainage area. The total estimated project cost is $150, OOD
with the funding for the project to come entirely from the Storm Core
Fund. The timing for the project would that it could be bid in June
and construction completed in July 1994 .
Brian Bourassa, PE, from OSM Engineering will provide an overview of
the project. Brian and staff will be available for any questions that
you may have. Staff recommends adoption of the resolution as stated
and proceed with the preparation of plans and specifications .

Re: Carrollton 4th Addition Feasibility Report
City of Rosemount
OSM Project No. 5414.00
Dear Mr. Osmundson:
At their meeting on April 5, 1994 the Rosemount City Council reviewed the Carrollton 4th
Addition Drainage Study prepared by OSM and recommended that staff prepare a
Feasibility Report for the completion of an additional outlet pipe from Carrollton 4th
Addition (Edwin Rahn Pond) to O'Leary's Pond.
c e
As stated in the Carrollton 4th Addition Drainage Study, the existing storm drain system
within the Carrollton Additions is adequate for the 100-year, 24-hour rainfall event.
However,additional drainage from surrounding areas has created a situation that may cause
flooding in the Carrollton 4th Addition. The purpose of the additional outlet pipe from '
Carrollton 4th Addition to the south is to provide flood protection for the drainage area and
to improve the reliability of the existing storm drain system in the Carrollton Additions
General Background
The project is located in the southeast quarter of Section 30 and the northeast quarter of
Section 31. The project location is shown on Drawing No. 1 at the end of this report.
Information relating to the existing conditions was given in the Carrollton 4th Addition
Drainage Study (see attached).
Proposed Improvements
The proposed storm drain improvements are shown on Drawing No. 2 at the end of this
report. The proposed storm drain improvements include the following:
- Minor grading in the Edwin Rahn Pond and at O'Leary's Pond.
- 21" RCP outlet pipe from Carrollton 4th Addition to O'Leary's Pond.
- Pipe jacking across C.S.A.H. 42.

Minor grading in the backyards of Block 3 of Carrollton 4th Addition in the area of the
storm drain construction will also be completed to improve the drainage in the area. The
minor grading at the Edwin Rahn Pond will include lowering the pond approximately 1-1/2
feet and excavation along the southem edge. The existing 12" outlet into the Carrollton
Addition storm drain will be eliminated. The excavation at O'Leary's Pond will take place
at the proposed storm drain outlet.
Approximately 1800 feet of 21" storm drain will be installed from the Edwin Rahn Pond to
O'Leary's Pond. The peak discharge from this storm drain into O'Leary's Pond is 18 cfs.
O'Leary's Pond is capable. of accommodating this flow. This proposed storm drain
construction may be a temporary outlet solution for Carrollton 4th Addition and the Edwin
Rahn Pond. In the future, when the comrnercial property located south of C.S.A.H. 42
develops, the stormwater from Carrollton 4th Addition and the Edwin Rahn Pond may be
routed to a different location on the site before discharging into O'Leary's Pond. Any future
development of the commercial property will need to consider this stormwater flow in the
drainage calculations.
The storm drain construction will iriclude the jacking of approximately 140 feet of a 36"
diameter steel casing pipe across C.S.A.H. 42.
Permits
A permit will be required from the Dakota County Highway Department for work within
the C.S.A.H. 42 right-of-way.
Easements
The construction of the proposed improvements within the Edwin Rahn Pond, Carrollton
4th Addition and the C.S.A.H. 42 will be within existing easements or right-of-way.
However, additional drainage and utility easements will be required from the parcel south
of C.S.A.H. 42. The owner of this parcel has been identified as the Chippendale/42
Partnership.
Temporary easements will be required from the e�sting property owners adjacent to the
proposed construction to allow for the contractor's operations.

EXECUTIVE SUMMARY
CARROLLTON 4TH ADDITION
FEASIBILITY REPORT
The Carrollton 4th Addition drainage improvements will provide flood protection for the
existing homes in the project area (Edwin Rahn Addition and Carrollton 4th Addition) and
will improve the existing storm drain system reliability. The proposed grading in Block 3
of Carrollton 4th Addition in the area of the proposed construction will increase the
backyard slopes to the outlet structure.
The project is feasible from an engineering standpoint. This Feasibility Report proposes the
co i "
nstruct on of a rolcimatel 1800 lineal feet of 21 diameter storm drain and minor
PP Y
grading at the Edwin Rahn Addition Pond, O'Leary's Pond and in Block 3 of Carrollton 4th
Addition. The total estimated project cost is $150,000. The funding for this project will
come entirely from the storm core fund.
The project construction can be initiated in July, 1994 with construction substantially
complete in July, 1994.
H:\5414A0\CI V IL\CORRES\EJ��CSUMM
Existing Conditions (From Carrollton 4th Draina�e Studvl
The existing storm drain system that provides the outlet for the backyards of Block 3 of
Canollton 4th Addition is also the outlet for the majority of Carrollton's 2nd and 3rd
Additions, the Edwin Rahn Addition {including one pond) and a portion of Broback lOth
Addition (see attached Drainage Area Map). Carrollton 4th Addition is located in the
Wachter Pond Drainage Distnct as delineated by the City of Rosemount's Drainage Plan
for the West Drainage Area(1989). The existing linear ponds located in the rear yard areas
of the Carrollton Additions are identified in the Drainage Plan as WAC 186A as shown on
the attached Drainage Pattern Map. The plats and grading plans for Carrollton 2nd, 3rd
and 4th Additions provide for linear ponds in the backyard areas. The existing low floor
elevation for the homes surrounding the Canollton 4th Addition stormwater pond is 954.8.
The subdivision drains from east to west and into a trunk storm drain on Shannon Parkway.
Ultimately, the stormwater from this area drains to Wachter Pond. As shown on the
Drainage Area Map,the Carrollton Addition development is constructed within a depression
which has no emergency overflow outlet to protect the homes in the event the existing storm
drain outlet becomes plugged.
The Edwin Rahn Addition is located directly east af Carrollton 4th Addition.
Approximately 24 acres of the Edwin Rahn Addition are tributary to a pond located on the
eastem boundary of Carrollton 4th Addition which has a 12-inch storm drain outlet flowing
into the Carrollton Addition storm drain system. The Drainage Plan identifies the Edwin
Rahn Addition pond as WAC 188D. As shown on the Drainage Pattern Map WAC 188D
was proposed to be outletted to the east across Chippendale Avenue. The existing low floor
elevation for the homes adjacent to the Edwin Rahn Addition pond is 958.2. T'he Edwin
Rahn Addition pond is separated from Carrollton 4th Addition by an earth berm (top of
bank elevation 955.8). In the past, the stormwater level in the Edwin Rahn Addition pond
has risen and has encroached onto Cimarron Avenue during critical rainfall events.
According to City staff, the stormwater in the pond drains out completely within a few days
of the rainfall event. This indicates that the underlying soils have a good percolation rate.
The City of Rosemount's Drainage Plan recommends that all trunk storm drains connecting
ponds be designed to accommodate the 100-year rainfall event a:�d that lateral storm drains
be designed to accommodate the 10-year rainfall event. The drainage plan also
recommends that low floor elevations near outletted ponds be at least two feet above the
100-year flood level. The original storm drain design, for Carrollton 4th Addition, was
based on a 10-year rainfall event.
We modeled the existing storm drain system and analyzed the 10-year,50-year and 100-year,
24-hour rainfall events. Table 1 lists the results of this analysis.

� As shown in Table 1, the e�usting storm drain system (with the inclusion of 24 acres from
the Edwin Rahn Addition) has the capacity to accommodate the 100-year, 24-hour rainfall
event in Carrollton 2nd and 3rd Additions, however, it does not have adequate capacity to
accommodate the 50-year or the 100-year, 24-hour rainfall events without inundating the
existing homes in Carrollton 4th Addition.
In addition to the potential for flooding in this area, the residents have expressed concerns
relating to the duration of standing water in the rear yards of Block 3, Carrollton 4th
Addition after rainfall events.
As stated eaxlier in this letter, the plats and grading plans for the Carrollton Additions
provide for stormwater ponding in the backyard areas. The result of allowing stormwater
to pond in backyard areas is that the turf will remain wet for a period of time after rainfall '
events.
The proposed grading plan for the Carrollton 4th Addition shows that a swale was to be
graded in the backyards of Block 3 to drain the area to a low point between Lots 7 and 8
and then outletted to the west by the proposed storm drain facility. A field survey of the
e�cisting backyards of Block 3 was completed in the fall of 1993. A comparison of the
proposed and existing backyard grading is shown below:
