PURGATORY CREEK DISTRICT
LOCATION
The southeast section of Shorewood, the only part of the
city not included within the Minnehaha Creek Watershed, is part
of the headwaters of Purgatory Creek and outlets via Purgatory
Creek southeast to the Minnesota River. Area indicated on the
district map as the Purgatory Creek District is only a small
portion of the total Purgatory Creek Watershed and includes
parts of Shorewood and contributing areas from the cities of
Deephaven, Minnetonka and Chanhassen which outlet through Shore-
wood to Purgatory Creek.
11 State Highway 7 crosses the northern tip of the district
and generally defines this border. Christmas Lake is to the
g Y
11 west. The easterly and southerly boundaries are sub-drainage
boundaries of the Purgatory Creek Watershed outside the city of
Shorewood.11 ,
Total drainage areas consist of 450 acres in Shorewood,
which includes 25 acres of Silver Lake and 75 acres of wetlands.
An additional 15 acres in Deephaven, 355 acres in Minnetonka and
125 acres in Chanhassen contribute to this district through
11 Shorewood.
I
TERRAIN
The Shorewood section of this district is outlined on the
west by a high ridge, with elevations up to 1035, which divides
-20-
1
I
I
Silver Lake from the Christmas Lake District. High, steep
slopes predominate along the west boundary. The remaining area
also downgrades rather steeply toward the wetlands, which are
approximately elevation 890 at the east Shorewood border.
1 The Minnetonka portion of this district slopes from high-
est elevations of up to 1000 , down to the central marshlands
area, which then outlet into Shorewood at approximately eleva-
11 tion 895 .
Within Chanhassen the area declines from highest elevations
1 of over 1030 to the Silver Lake wetlands at elevation 900 .
LAND USE
According to the Shorewood Zoning Ordinance almost the en-
tire area within Shorewood is zoned R-1, single family (estate) .
The exception is approximately 7 acres in the northeast corner,
south of State Highway 7 and west of Vine Hill Road, which is
11 zoned C-3 , general commercial.
Areas designated as wetlands within Shorewood are outlined
on the drainage maps for this district.
EXISTING DRAINAGE SYSTEM - PLATE la
State Highway 7 , through its system of ditches and culverts,
provides drainage for contributing areas of Shorewood, Deephaven
and Minnetonka, and outlets into the marshland in the city of
11 Minnetonka. These marshes then overflow west into Shorewood
through a 30" concrete culvert under Vine Hill Road north of
11 Hanus Road.

The area of Chanhassen and that of S r portion Shorewood gener-
ally south of Covington Road (including Silver Lake) drains to
the north through a 24" culvert under Covington Road, west of
Vine Hill Road.
' Drainage from these two areas joins runoff from the remain-
ing portion of Shorewood within this district, north of Coving-
ton Road. Storm water then flows east into the city of Minne-
tonka via a 72" x 54" arch culvert under Vine Hill Road north of
Covington Road. This runoff follows a branch of Purgatory Creek
through Minnetonka to its outlet into the Minnesota River.
Approximately 10 acres in Shorewood along Vine Hill Road
south of Manchester Street, drains to a low area on the west
side of Vine Hill Road . Its natural overflow would be east
11 across Vine Hill Road and overland through the city of Minne-
tonka to the Purgatory Creek Branch.
Runoff from another 3 acres of Shorewood, along Vine Hill
' Road north of Shady Hills Rd, collects in a small depression on
the west side of Vine Hill Road. The natural overflow for this
area is to the east across Vine Hill Road into the city of Minne-
tonka.
In the Shady Hills area, there is an 18" culvert across
IIShady Hills Rd, east of Shady Hills Circle, which directs runoff
south to the wetlands. West of Shady Hills Circle there is a
11 deep depression at elevation 957 with a natural overflow to the
southwest across elevation 967.

LAKES AND PONDING AREAS
ISilver Lake is completely surrounded by wetlands, and out-
11 lets to the east through a branch of Purgatory Creek from the
northeast corner of the lake. Water elevation was 896 .5 in Oct-
ober 1967 which is assumed as normal overflow elevation to the
outlet channel.
The total Silver Lake basin includes approximately 300
11 acres. There are approximately 38 acres of wetlands in Shore-
wood and 27 acres of marshland in Chanhassen adjacent to Silver
Lake, which has a water surface area of 25 acres. An additional
110 acres in Shorewood and 100 acres in Chanhassen comprise the
remainder of the lake basin. A 24 hour 100 year storm will con-
1 tribute 71 acre feet of runoff which could cause a maximum rise
of 0.8 feet in Silver Lake and the wetlands.
The small wetlands area east of Covington Road and south of
Radisson Road has a natural overflow to the east at elevation
1004 with a total water surface area of 2 acres and a total con-
tributing area of 7 acres. This wetlands can contain the runoff
from a 100 year storm with storage of more than 2 acre feet.
' The wetlands area south of Shady Hills Rd between Vine Hill
Road and Shady Hills Circle has a water surface area of 1 acre
at elevation 931.5 and a storage capacity of 4 acre feet to ele-
1 vation 935 . A contributing area of approximately 25 acres will
produce 3 .5 acre feet runoff into the wetlands from a 24 hour
100 year storm. The natural overflow is south into the wetlands
west of Kingswood Terrace.

' PROPOSED DRAINAGE SYSTEM - PLATE lb
Proposed storm sewer on Ridge Road would intercept the low
11 points along the road and carry the runoff to the Silver Lake
wetlands. Also, there will be storm sewer on Covington Road
from Ridge Road to the wetlands area. This pipe will also inter-
cept drainage from the north side of Covington Road and direct
it into Silver Lake wetlands to the south. It may be necessary
to raise the street elevation on Covington Road at its low point
to provide adequate drainage south to the wetlands.
Storm sewer in the Shady Hills area would include pipe on
Shady Hills Rd from Shady Hills Circle to Shady Lane. This pipe
would then be directed south to the wetlands area. The outlet
' pipe for this wetlands pond is south to the wetlands west of
Kingswood Terrace.
' The proposed drainage plan for the area in Shorewood south
of Shady Hills and north of Covington Road will continue to uti-
lize the open channel flow between the wetlands areas. Storm
1 sewer from the west to the open channel follows the natural
drainage pattern.
' Existing Highway 7 drainage completes the storm sewer for
this district.
' INTERCOMMUNITY PARTICIPATION
11 Drainage from the three adjacent communities is through the
wetlands in Shorewood and culverts under Covington Road and Vine
1 Hill Road. No other storm sewer carrying flow from more than
one community are existing or proposed in this district.

CARSON BAY DISTRICT
LOCATION
' This district includes the northeast corner of Shorewood as
well as an area south of Highway 7 which drains across Highway 7
to the north. Total area of Shorewood within the district is
235 acres , which includes 30 acres of wetlands and 5 acres of
Highway 7 right-of-way. 270 Acres of the city of Deephaven to
the east and the north are also in this watershed.
TERRAIN
The terrain in this district is generally rolling, with a
number of depressions. The general direction of ground slope
is northward to Carson Bay, Lake Minnetonka.
' The highest ground in this district is approximately eleva-
tion 1044 in the southern portion near Highway 7 . The lowest el-
evation in Shorewood is in the north wetlands at elevation ap-
proximately 940 . Ground elevation at Carson Bay is 930 .
LAND USE
' The entire area within Shorewood is zoned residential.
However, the Amesbury development north of Manor Road has been
' included as a Planned Unit Residential Development. An R-3 , two
family, designation has been assigned the area between Excelsior
Boulevard on the north to State Highway 7 on the south. The re-
IImainder of the District is zoned R-1 , single family (estate) ex-
cept for that small portion, south of Manor Road and east of St.
' Alban' s Bay Road, zoned R-2 , single family.
-25-
Shorewood' s wetlands areas for this District are indicated
on the drainage system plans .
' EXISTING DRAINAGE SYSTEM - PLATE 2a
The area of Shorewood south of Highway 7 has several small
depressions which pond the runoff. Natural overflow is north to
the low areas adjoining Highway 7 . It is then carried by cul-
vert across Highway 7 to the wetlands and ditches on the north.
The direction of overflow from these ditches on the north-
side of Highway 7 is north by storm sewer pipe along a State
Highway Department drainage easement to the large wetlands pond
' north of Excelsior Boulevard..
Existing storm sewer in the Amesbury Development is delin-
eated on the existing storm sewer map. This drainage then out-
lets overland through Deephaven into Carson Bay, Lake Minnetonka.
' LAKES AND PONDING AREAS
The wetlands located south of Excelsior Boulevard, east of
St. Alban' s Bay Road and north of Trunk Highway 7 , includes
' 1-1/2 acres of water surface area at elevation 978 . Natural
overflow is to the southeast over elevation 993. There are ap-
proximately 16 acres contributing to this pond. A 24 hour 100
year storm would contribute approximately 3 acre feet of runoff
which would raise the water level to elevation 980 . As this is
such a deep depression, allowing large fluctuations in water
surface elevation, no outfall has been included in this report.
If an outfall is required, it would flow by storm. sewer pipe
east along St. Alban' s Bay Road to Highway 7 , then north to the
' wetlands pond north of Excelsior Boulevard.
-26-
This wetlands pond north of Excelsior Boulevard extends up
to Manor Road. It has a surface area of 10 acres at normal ele-
vation 954. The small pond of 1-1/2 acres , on the north side of
' Manor Road has a normal elevation of 953.7 with a high water of
955. 2. No culvert across Manor Road connecting these ponds was
located in the field survey.
Existing storm sewer in the Amesbury Development carries
' the overflow from these ponds to the north where it outlets into
the wetland area and then flows overland through Deephaven into
Carson Bay.
PROPOSED DRAINAGE SYSTEM! - PLATE 2b
Existing culverts and ditches for State Trunk Highway 7
drainage will continue to be utilized in the proposed storm
' sewer system.
As further development occurs , additional lateral storm
' sewer may be required. Laterals should follow drainage patterns
for these areas as indicated on the existing storm sewer plan.
No attempt has been made to size any storm sewer pipe out-
lets through the city of Deephaven.
INTERCOMMUNITY PARTICIPATION
' An area from Deephaven drains into Shorewood and through
its drainage system to the north border of the city. Runoff
' entering Deephaven along this border then flows overland in a
northerly direction to Carson Bay, Lake Minnetonka.
-27-
Cooperative agreements between Shorewood and Deephaven
' should be obtained prior to construction of additional storm
sewer in this district.

' Drainage is generally overland to the wetlands and small
' low areas. The existing drainage plan shows the natural over-
flow to Lake William. Existing culverts are delineated on this
map.
LAKES AND PONDING AREAS
' Lake William has a water surface area of 18 acres. U.S .G.S.
' Quadrangle revised 1972 indicates the depth of Lake William is
approximately 4 feet. This lake may have been a bay of Lake
tMinnetonka prior to the construction of Minnetonka Boulevard and
the C. & N.W. Railroad. Field investigations revealed no outlet
pipe to Lake Minnetonka from Lake William. The area contributing
' to Lake William is approximately 100 acres. A 24 hour, 100 year
storm could produce 22 acre feet of runoff to the lake causing a
rise of 1.2 feet. Proposed normal elevation of Lake William is
931. 5 with a high water elevation of 932 . 7 and a 3 cfs overflow.
' The wetlands in this district are isolated depressions gene-
rally less than one-half acre in area with small contributing
areas.
PROPOSED DRAINAGE SYSTEM - PLATE 3b
Proposed drainage system is to provide storm sewer on the
' existing streets in this district and carry the runoff to Lake
' William.
-30-
In the unplatted areas , east of Suburban Drive, wetlands
will be utilized for small ponding areas. Lateral Storm sewer
pipe may be required at the time the area is developed.
' INTERCOMMUNITY PARTICIPATION
Intercommunity participation would be required for the
storm sewer on Minnetonka Boulevard which carries runoff from
the adjacent properties in Greenwood to Lake William.
' At the time an outlet for Lake William to Lake Minnetonka
is required, an easement through Greenwood will be necessary.

' ST. l_I?AN 'S BAY nISTRICT
LOCATION
This area is generally bounded by State Highway 7 on the
' south and St. Alban' s Bay Road on the east and north. A small
' area of Shorewood north of St. Alban' s Bay Road from Manor Road
to Minnetonka Boulevard is included in this district.
Drainage area for this district includes approximately 70
acres of Shorewood and approximately 100 acres of Greenwood.
' TERRAIN
The area of Shorewood in this district is generally high
' ground, above elevation 970 , and up to elevation 1040 . The area
slopes steeply from St. Alban' s Bay Road to St. Alban' s Bay, at
elevation 930.
LAND USE
According to Shorewood' s ordinance, this district is zoned
' R-1 single family (estate) south of the intersection of Manor
' Road and St. Alban' s Bay Road. The north portion is zoned R-3 ,
two family.
No wetlands have been designated in this area.
EXISTING DRAINAGE SYSTEM - PLATE 4a
' Existing system collects the runoff from Shorewood north-
east of St. Alban 's Bay Road into two storage areas located in
the District. Culverts direct runoff into the pond located at
' the intersection of Suburban Drive, St. Alban's Bay Road and
Manor Road.
I
-32-
1
1
Another culvert on Manor Road, north of Highway 7, directs
' flow from the low area south of Manor Road across Manor Road to
St. Alban's Bay.
LAKES AND PONDING AREAS
The pond at Suburban Drive and Manor Road has a water sur-
face area of 1-1/2 acres. The normal for this pond is elevation
' of 987 .5 . This will provide over 2 acre feet of storage which
is adequate to contain a 24 hour 100 year storm. There is an
' existing overflow culvert for this pond south across St. Alban' s
Bay Road to the east ditch of Manor Road.
A depression located north of St. Alban' s Bay Road and west
of Suburban Drive collects runoff from a small area of Shorewood
Iin this district. When storm sewer for this area is required,
it would outlet approximately 400 feet to the west on an ease-
ment through Greenwood to St. Alban' s Bay.
' PROPOSED DRAINAGE SYSTEM - PLATE 4b
' Proposed drainage system would continue to use the pond at
Suburban Drive and Manor Road. Additional storm sewer required
' to direct runoff to St. Alban's Bay is delineated on the propos-
ed plan.
-33-
I
I
INTERCOMMUNITY PARTICIPATION
No areas of Greenwood are served by the Shorewood storm
sewer system.
Shorewood would require easements from Greenwood to outlet
through their community into St. Alban 's Bay.

CHRISTMAS LAKE DISTRICT
1 LOCATION
Christmas Lake district includes areas of Shorewood, Chan-
hassen, and Excelsior. Boundaries of the district are generally
' defined by State Highway 7 on the north, County Road 82 on the
west, and the high ridge between Christmas Lake and Silver Lake
on the east.
Total contributing area in Shorewood, exclusive of approx-
1 imately 245 acres in Christmas Lake, consists of 245 acres. In-
cluded are 9 acres of Lake Como and 12 acres of wetlands. An
additional 35 acre area on the northwest side of the district is
1 drained, along with the area of Excelsior shown within this dis-
trict, through the Excelsior storm sewer system to St. Alban' s
Bay. There are 270 acres contributing, and 20 acres of Christ-
1 mas Lake in Chanhassen.
TERRAIN
The terrain on the east is characterized by the steep bank
of the high ridge between Christmas Lake and Silver Lake. The
highest elevation in this area is approximately 1030 , with the
' elevation at Christmas Lake of 932 .
On the north, between Christmas Lake and Highway 7 , there
1 is one peak which reaches an elevation of approximately 1000 .
To the west in Shorewood and the south in Chanhassen the
1 terrain is generally rolling, with some low depressions. The
highest elevation in Shorewood is approximately elevation 1000
and in Chanhassen 1050 .
-35-

' LAND USE
Shorewood' s land area in the Christmas Lake district is
primarily zoned R-1 single family (estate) . A 4 acre area along
Highway 7 at the northwest corner of Christmas Lake is zoned R-3 ,
two family. Another small area north of County Road 82 and west
of Christmas Lake is R-2 single family.
' Areas in Shorewood designated as wetlands are indicated on
' the drainage map for this district.
EXISTING DRAINAGE SYSTEM - PLATE 5a
Storm sewer in Excelsior and drainage along Highway 7 and
County Road 82 (Mill St. ) are delineated on the existing storm
' sewer manp.
Runoff from the bluff along the east side of Christmas Lake
is directly to the lake. Drainage in Shorewood on the west side
of Christmas Lake is generally northerly and enters Christmas
Lake on the northwest side. A small area southeast of Christmas
Lane drains to Christmas Lake at the south Shorewood border.
I
The northwest portion of Shorewood in this district outlets
through the Excelsior Storm Sewer System.
The drainage in Chanhassen is generally to the east through
a natural creek bed and enters Christmas Lake on the south in
Chanhassen.
' The outlet for Christmas Lake is north by culvert under
Highway 7 along the Excelsior Greenwood border to St. Alban's
Bay.

-36-
' LAKES AND PONDING AREAS
' The Natural Ordinary High Water (N.O.H.W. ) for Christmas
Lake established by Commissioner 's order dated 7-13-44 is at
elevation 932. 76. With a water surface area of 265 acres and a
contributing area of approximately 500 acres , there would be 195
acre feet runoff to the lake from a 100 year 24 hour storm.
This could cause a maximum rise of . 74 feet in the water surface
elevation.
' Lake Como, located north of Christmas Lake and south of
Highway 7, has a water surface area of 9 acres with a contribu-
ting area of 18 acres. There is not enough area contributing di-
rectly to Lake Como to maintain this lake elevation at a normal
' level. If it is desired to control the lake at an established
elevation, some method of introducing additional water, such as
a small well, must be provided.
' There is a wetlands on the west side of Christmas Lake Road
which is proposed as a storage area. With a surface area of
3-1/2 acres , a normal elevation of 947 and a high water eleva-
tion of 948 with an 8 c.f.s. outlet will control the runoff from
a 100 year storm.
' The natural overflow for other wetlands areas is delineated
on the existing storm sewer map.
11 PROPOSED DRAINAGE SYSTEM - PLATE 5b
Storm sewer proposed on the west side of Christmas Lake
would carry runoff from Chrismas Lake Road and Hillendale Road
to the wetlands storage area on the west. This wetland outlets
by open channel to Christmas Lake.
-37-
A portion of the remainingarea west of Christmas Lake in
Shorewood outlets into Excelsior to their existing storm sewer
system.
' Other storm sewer proposed in this district, within the
' city of Shorewood, would drain the low points on Christmas Lake
Point, Merry Lane and Radisson Road into Lake Como, the wetlands ,
' or Christmas Lake.
No storm sewer is required on the east side of Christmas
' Lake as drainage is overland down the steep bank directly to the
lake.
INTERCOMMUNITY PARTICIPATION
' Shorewood will require continued use of the existing storm
sewer system in the city of Excelsior.
' No common storm sewer carries runoff from both Shorewood
and Chanhassen in this district.

' GALPIM LAKE DISTRICT
LOCATION
Galpin Lake is located south of State Highway 7 with the
north portion of the lake within the city limits of Excelsior,
' and the south portion in Shorewood.
The eastern boundary of the district generally follows
County Road 82 (Mill St. ) The westernmost location is near the
intersection of State Highways 7 and 41. State Highway 7 inter-
sects this district diagonally from southwest to the northeast.
An area of Shorewood lies north of Highway 7 on the west side of
' this district.
A portion of the city of Chanhassen is included in this
' watershed as well as an area from the city of Excelsior. Galpin
Lake contributing area includes 275 Shorewood acres of which 9
tacres are wetlands. Additionally, there are approximately 115
acres in Chanhassen, 50 acres from Excelsior and 50 acres of
' water surface area in Galpin Lake.
' TERRAIN
Highest ground in this district is in the south portion,
' with elevations up to 1065 in Shorewood and 1075 in Chanhassen.
The ground elevation at Galpin Lake is 943.
LAND USE
The area east of Apple Road is zoned R-1, single family
(estate) . The majority of the remaining area within this dist-
ilrict is zoned R-2 , single family. Land usage south of Highway 7
and north of Murray Hill Road has a R-3 , two family designation.

There are two C-3 , general commercial areas, north of High-
way 7 : The area across from State Highway 41, and across from
the west end of Galpin Lake.
Designated wetlands areas are indicated on the drainage map.
EXISTING DRAINAGE SYSTEM - PLATE 6a
The west area of Shorewood, north of Highway 7 , and areas
adjacent to Highway 7 on the south, follow Highway 7 drainage to
' Galpin Lake. A portion of the area north of Highway 7 contri-
butes to Excelsior' s storm sewer system which also outlets into
Galpin Lake .
Areas south of Galpin Lake drain to wetlands, small ponding
' areas and to Galpin Lake by overland flow.
Galpin Lake outlets north to Lake Minnetonka through High-
way 7 and Excelsior storm sewer systems.
1 LAKES AND PONDING AREAS
Galpin Lake is within the corporate limits of both Shore-
wood and Excelsior. The Natural Ordinary High Water (N.O.H.W.)
level on Galpin Lake , established by Commissioners order dated
1 September 26 , 1941, is 943 . 26 . Its controlled outlet is at the
' northeast corner of the lake and east through the Excelsior and
Hennepin County storm sewer system to Lake Minnetonka. A second
outlet, near Elm Place , crosses Highway 7 to Mud Lake. Mud Lake
then outlets through the Excelsior system to Lake Minnetonka.
' A 24 hour 100 year storm would contribute approximately 80
acre-feet of runoff to Galpin Lake. This could cause the lake
to rise a maximum 1. 6 feet.

' Further analysis of the two outlets should be made in co-
operation with the communities and the highway department. This
would require study as to their condition, elevations and capa-
cities, and proposed revisions to eliminate flooding problems
' which are occurring downstream.
' Another ponding area within this district, is in the city
of Excelsior near College Avenue and Water Street. The overflow
' from this pond is through the Excelsior storm sewer system into
Galpin Lake.
' Two areas included in Shorewood' s wetlands are proposed
storage basins. The first is located partially in Chanhassen
and partially in Shorewood, east of Galpin Lake Road. A normal
elevation of 964 . 5 and high water elevation of 965 .5 would re-
quire a 6 cfs outlet for 100 year storm design.
' Storage is also proposed in the wetlands immediately south-
east of Galpin Lake. A normal elevation of 944 .5 , and a high
water elevation of 947 would provide 11.5 acre feet of storage.
A 5 cfs outlet will be required for 100 year storm design.
PROPOSED DRAINAGE SYSTEM - PLATE 6b
' The proposed system would continue to utilize the existing
Highway 7 drainage ditches and culverts.
Storm sewers south of Highway 7 along existing streets are
' designed with capacity to carry the runoff from contributing
areas of Chanhassen.
-41-

I
Proposed storm sewer on Grant Street and Park Street north
of Highway 7 outlets via the Excelsior storm sewer system into
Galpin Lake.
INTERCOMMUNITY PARTICIPATION
A continued use will be required for the storm sewer north
of Highway 7 which carries Shorewood runoff through the city of
' Excelsior.
Cost sharing with the city of Chanhassen should be agreed
' upon prior to construction of storm sewer south of Highway 7
' which would carry flows from Chanhassen through Shorewood into
Galpin Lake.

GIDEON BAY DISTRICT
' LOCATION
The Gideon Bay District is that watershed which outlets in-
to Gideon Bay through Shorewood and Tonka Bay west of the Excel-
' sior city border. This district is outlined by Lake Minnetonka
and a portion of the city of Tonka Bay on the north, County Road
' 19 on the east in Excelsior, and Manitou Lane and Glen Road on
the northwest in Shorewood. The southern most location in this
district is south of Yellowstone Trail near Excelsior.
' This district consists of approximately 310 acres in Shore-
wood, including 5 acres of wetlands, 80 acres in Excelsior, and
' 70 acres in Tonka Bay.
' TERRAIN
The highest elevations in this district approach 1000 in
' the western portion. There are also elevations up to 1010 in
the area south of Glencoe Road and Yellowstone Trail. Lowest
' elevations are 930 at Lake Minnetonka.
' LAND USE
This district is zoned R-1 , R-2 , R-3 , R-4 , R-5 and C-3 .
Generally the higher densities are adjacent to both Excelsior
and Tonka Bay and along County Road 19 . The commercial areas
' are along the Tonka Bay, Shorewood border.
Wetlands areas are as shown on the drainage plan.
i
-43-
' EXISTING DRAINAGE SYSTEM - PLATE 7a
The southeastern portion of this district drains into the
' city of Excelsior through the marshlands, which then overflow
through Shorewood via culverts under County Road 19 and the
M. & St. L. railroad into Gideon Bay.
An interior district drains through Badger Park by storm
sewer and a ditch system which directs the flow across County
Road 19 , by culvert, east of Tonka Bay. A drainage channel then
flows in a northeasterly direction to a wetlands south of the
' M. & St. L. tracks. Drainage then outlets north through the
culverts under the railroad and Lafayette Avenue into Gideon Bay.
The remaining western area of Shorewood and most of Tonka
' Bay in this district drain to two wetlands areas near the tracks.
One of these areas is east of County Road 19 , the other is to the
west. No outlets were found for either location.
LAKES AND PONDING AREAS
There are no lakes within this district.
' The wetlands and depressions in Shorewood and the marshland
in Excelsior provide settlement before outletting into Gideon
Bay.
PROPOSED DRAINAGE SYSTEM - PLATE 7b
Proposed drainage system utilizes existing culverts under
' County Road 19 and culverts and ditches under and along the
M. & St. L. railroad.
The area which includes Minnetonka Drive, Clover Lane, and
McLain Road has proposed storm sewer which outlets into the
marshlands in Excelsior. The southernmost portion of this dis-
trict along Glencoe Road and Yellowstone Trail also outlet into
-44-
' this marshland, Proposed Lake Mary overflow is into this
district on Clover Lane.
' Storm sewer system in the Badger Park area will continue to
' use the existing ditches and culverts. Some additional storm
sewer extensions are also proposed.
tProposed storm sewer in the western section will outlet
into Gideon Bay through the city of Tonka Bay. Existing wet-
lands areas and small ponding areas will allow settlement for a
' portion of the runoff before discharging into Lake Minnetonka.
INTERCOMMUNITY PARTICIPATION
' Shorewood and Excelsior will require continued use of the
marshlands and outlet for common drainage into Gideon Bay.
' Tonka Bay and Shorewood will require an agreement prior to
construction of storm sewer which will serve both communities.

' LAKE MARY PISTRICT
LOCATION
The Lake Mary district is located generally south of Coun-
ty Road 19 , north of State Highway 7 , east of Country Club Drive
and west of the city of Excelsior. There is a total of 90 acres
in this watershed which is entirely within the city limits of
Shorewood. Twenty five acres of this area is wetlands and lakes.
' TERRAIN
The highest locations in this district are on the southern
boundaries at elevation 1035. The terrain slopes generally
northward to Lake Linden, at elevation 957 and then to Lake Mary
at elevation 952. There is a small depression southwest of Lake
' Mary and two small wetland areas southwest of Lake Linden.
11 LAND USE
According to Shorewood 's zoning ordinance, this area is
' zoned R-1 single family (estate) in the western portion and R-2
single family in the east. There is a small one acre section,
zoned C-3 general commercial, east of Linden Drive at the south
district border.
Wetlands include two 1/2 acre areas southwest of Lake
11 Linden.
EXISTING DRAINAGE SYSTEM - PLATE 8a
Drainage is overland to the lakes, wetlands and low areas.
The field survey located a 12" culvert across Linden Drive south
t
-46-
I
1 of Yellowstone Trail. This directs the overflow from the wet-
lands area west of Linden Drive into Lake Linden. Another 12"
culvert under Yellowstone Trail on the west side of the district
carries runoff north to the depression southwest of Lake Mary.
The natural overflow for this district is at the northeast
corner of Lake Mary, east into the Gideon Bay District on Clover
11 Lane.
LAKES AND PONDING AREAS
Lake Linden is a 2-1/2 acre lake on the south side of Yel-
lowstone Trail. Contributing area is approximately 35 acres pro-
viding a land to water ratio of 14 to 1. This is adequate to
maintain Lake Linden with some fluctuations throughout the year.
The natural overflow of Lake Linden is to Lake Mary across Yel-
lowstone Trail. Proposed normal elevation is 957 with a high
water elevation of 959 .5 and 3 cfs overflow.
Lake Mary has a water surface area of approximately 11
acres with 33 acres contributing. This provides a land to water
1 ratio of 3 to 1. When the proposed storm sewer is constructed,
there will be an additional 12 acres draining to Lake Mary from
the depression southwest of Lake Mary. This will then provide
a land to water ratio of 4 .1 to 1.
11 The proposed overflow from the central district, west of
the Lake Mary district, is into Lake Mary. This will provide an
additional 25 acres drainage directly to Lake Mary which will
' increase the land to water ratio to 6 .4 to 1. If the Minnetonka
-47-
1
Country Club is developed as residential , according to Shore-
wood' s zoning plan, there is a proposed ponding area which will
also overflow in to Lake Mary. With this additional runoff
entering Lake Mary, it should be possible to maintain the lake
without extreme fluctuations.
Proposed normal elevation for Lake Mary is 952 .0 with a
' high water elevation of 954 .5 and 6 cfs overflow.
PROPOSED DRAINAGE SYSTEM - PLATE 8b
Proposed storm sewer will drain the low points on Echo Road
into Lake Mary. Runoff from the low area in the west of the
district north of Yellowstone Trail will be carried northward to
join the overflow pipe from the central district into Lake Mary.
Storm sewer on Linden Drive will pick up the overflow from
the wetlands areas and direct them into Lake Linden. An over-
flow pipe from Lake Linden into Lake Mary across Yellowstone
Trail is included, as well as an overflow pipe from Lake Mary
1 into the Gideon Bay District.
INTERCOMMUNITY PARTICIPATION
' As this drainage area is entirely within Shorewood, no
inter-community storm sewer participation is required.

i CENTRAL_ DISTRICT
LOCATION
The central district is entirely within Shorewood and con-
sists primarily of the Minnetonka Golf Course. Bounded by
Smithtown Road on the north, Country Club Road on the east,
Yellowstone Trail on the south and Seamans Drive on the west,
this district has a total area of 150 acres. There are no wet-
lands or lakes included.
' TERRAIN
The highest elevations are in the southwest corner at ap-
proximately 1010. In the northeast, near the Club House, the
ground elevation is approximately 1000. The lowest elevations
' are at the south central portion of the district, ground eleva-
tion 957, and on Country Club Road, elevation 960.
LAND USE
' The land in this area is zoned R-1, single family (estate) .
Present usage, however, is golf course, except for a few homes
around the perimeter of the district.
' EXISTING DRAINAGE SYSTEM - PLATE 9a
Approximately 125 acres drain to the low area in the center
of the district north of Yellowstone Trail. A 24" tile line
Drains the overflow from this area to the Lake Minnewashta Dis-
11 trict as shown on the existing drainage map.
The east portion of the golf course drains to 2 small ponds
adjacent to Country Club Road, north of Yellowstone Trail.
A 12" tile line drains the overflow from these ponds west to the
low area in the center of the district.
-49-
1
1
LAKES AND PONDING AREAS
A 6 .5 acre pond is proposed in the south central section of
the golf course if this area is developed. Normal elevation
would be 958 .5 , with high water of 960 .5 . This would provide 13
' acre feet of storage with an 8 . 3 c. f.s. outfall for a 100 year
storm design.
PROPOSED DRAINAGE SYSTEM - PLATE 9b
Future lateral storm sewer should follow the natural
drainage patterns as indicated on the existing drainage map if
the area is developed. Storm sewer on Yellowstone Trail at the
south edge of this district would divert a 6 acre area of the
Lake Minnewashta District into this area.
The outlet for the proposed pond would be easterly to Coun-
try Club Road and from there into the Lake Mary District.
INTERCOMMUNITY PARTICIPATION
' As this drainage district is entirely within Shorewood's
' boundaries, no intercommunity participation is required.

' SOVTH CENTRAL DISTRICT
LOCATION
The south central district is a self contained drainage
' basin which is bisected north-south by State Highway No. 7 near
the south Shorewood boundary. There are 44 acres of Shorewood
which includes a 5-1/2 acre pond and 1/2 acre wetlands. Twenty
eight acres from Chanhassen also contribute to this district.
' TERRAIN
' Highest ground elevation within Shorewood in this district
is elevation 1000. The ground slopes to a deep depression in
the center of the district at elevation 961.
LAND USE
The area within the city of Shorewood is zoned R-1 single
' family (estate) .
EXISTING DRAINAGE SYSTEM - PLATE 10a
Existing drainage within the city of Shorewood is overland
into the pond north of Highway 7 in the center of the district.
State Highway 7 drainage within this district also outlets into
' this pond.
The area in Chanhassen drains to Highway 7 , or to a small
' pond in Chanhassen.
LAKES AND PONDING AREA
There is only the one existing pont in the city of Shore-
wood within this district. As there is no outlet for this
1
-51-
1
pond, it will continue to fluctuate with rainfall, evaporation,
and ground water seepage. There is an approximate 10 to 1 ratio
' of contributing land area to water surface area. Extreme fluct-
uations in the water level are therefore not anticipated.
As the water surface elevation of this pond is considerably
lower than the adjacent homes or Highway 7 , no outlet has been
' designed. If an outlet is required sometime in the future, it
could be provided by a gravity pipe to the west into the Lake
Minnewashta district. Another alternative would be temporary
pumping into another district to lower the water elevation to an
acceptable level.
' PROPOSED DRAINAGE SYSTEM - PLATE 10b
1 Proposed drainage system is to intercept the low points on
the existing streets in Shorewood and direct them into the pond.
Existing Highway 7 drainage would continue to be utilized.
INTERCOMMUNITY PARTICIPATION
If it is necessary to provide a gravity outlet or temporary
' pumping, then participation would be required between Shorewood,
Chanhassen and the Minnesota State Highway Department.

LAKE MINNEWASHTA DISTRICT
LOCATION
' Lake Minnewashta is entirely within the city of Chanhassen,
as is the majority of the drainage area, except for 45 acres of
Shorewood and some contributing area in Victoria. This area of
' Shorewood is generally north of Highway 7 , centered near the
intersection of Highway 7 and Yellowstone Trail. Water sur-
face area of Lake Minnewashta is approximately 675 acres. A
11 study of the entire Lake Minnewashta watershed is not included
in this report as only a small area of Shorewood is contributing.
' TERRAIN
The highest elevations in Shorewood are 1005 along the
north boundaries of the district. Slopes are generally south
' across State Highway 7 to Lake Minnewashta, immediately south of
Shorewood in Chanhassen. Water surface elevation of Lake Minne-
' washta, according to the U.S . G.S . Map, is 944 .
LAND USE
This area of Shorewood is zoned R-1, single family (estate) ,
' in the east section and R-2 , single family, in the west. A sig-
nificant portion of this district is Highway 7 right-of-way.
EXISTING DRAINAGE SYSTEM - PLATE lla
The existing drainage system utilizes Highway 7 culverts
' and ditches, which then outlet into Lake Minnewashta.
' There is an existing 18" storm sewer. in Chanhassen along
Washta Bay Road where drainage from Shorewood, Highway No. 7 ,
-53-
' and a small area of Chanhassen drain to Lake Minnewashta. An-
other culvert under Highway 7 outlets directly into Lake Minne-
washta. No other existing culverts in Shorewood were located
during our field survey.
' LAKES AND PONDING AREAS
' Lake Minnewashta outlets to the west by a creek from the
northwest corner of Lake Minnewashta into Lake Virginia. Lake
Virginia, in turn, outlets to the west to Lake Minnetonka.
No ponding areas in Shorewood are included in this district.
' PROPOSED DRAINAGE SYSTEM - PLATE llb
' Proposed drainage system diverts an area of approximately 6
acres north of Yellowstone Trail into the central district. The
remainder of the district will continue to use existing Highway
7 drainage into Lake Minnewashta.
' INTERCOMMUNITY PARTICIPATION
' Shorewood' s runoff into Lake Minnewashta is via the Highway
7 drainage system. No other common storm sewer is existing or
proposed.

NORTH CENTRAL DISTRICT
LOCATION
This district is bounded by Club Road and Manitou Lane
on the east. Mann Lane is the southernmost location in the dis-
trict. Grant Lorenz Road on the west, and Lake Minnetonka and
a portion of the city of Tonka Bay on the north complete the
outline of the district.
Approximately 300 acres of Shorewood, including 24 acres of
' wetlands, are in this district. There are also 90 contributing
' acres in Tonka Bay, of which 40 acres are marshland.
TERRAIN
' The highest locations in this district are in the south
central section where the elevation reaches 1000 . Ground slopes
rare generally northward to the common wetlands between Tonka Bay
' and Shorewood at elevation 930 .
LAND USE
To the west and north of Smithtown Road, the zoning is R-2 ,
single family. The portions of the district in the extreme
west, and south of Smithtown Road, are zoned R-1 single family
' (estate) .
Wetlands in Shorewood and marshlands in Tonka Bay comprise
a large portion of the district.
EXISTING DRAINAGE SYSTEM - PLATE 12a
' On the east side of the district, the field survey located
two culverts under the M. & St. L. tracks which allows runoff to
follow natural drainage channels northward into the wetlands.
-55-
1
' Overflow for these marshlands is westward to the open ditch out-
let into Lake Minnetonka along the west Tonka Bay, Shorewood
border.
In the western drainage area runoff collects in the wet-
lands and low areas. Overflow is northward into the wetlands ad-
joining Tonka Bay.
Areas in Shorewood adjacent to Lake Minnetonka and north of
Birch Bluff Road drain directly to the lake.
LAKES AND PONDING AREAS
The small wetlands areas will continue to be used as settle-
ment basins before overflowing.
The marshland areas in Shorewood and Tonka Bay, include a
' total of approximately 55 acres. With a contributing area of 335
' acres, a 24 hour 100 year storm could cause a maximum rise of
1.3 feet in the marsh area.
IAs a portion of the outlet ditch is lower than Lake Minne-
tonka, there is standing water at times. One solution to this
problem would be to raise the level to that of Lake Minnetonka
to provide adequate drainage . A further analysis as to the
existing elevations and proposed outlet levels would be required.
PROPOSED DRAINAGE SYSTEM - PLATE 12b
Proposed storm sewer carries runoff from the south section
to the west and then north to the M. & St. L. railroad. From
' there it follows northeasterly along the tracks, then north into
the wetlands. The two open channels which flow northward from
11
-56-
1
1
1
the tracks into the wetlands sould be continued to be used, how-
' ever, until such time as a storm sewer may be required.
The western area of this district drains northeasterly into
' the wetlands as indicated on the proposed drainage map.
' INTERCOMMUNITY PARTICIPATION
The common marshland area and its outlet will require an
1 agreement between Shorewood and Tonka Bay.
There is no other storm sewer proposed which serves both
' Shorewood and Tonka Bay.

WEST CENTRAL DISTRICT
' LOCATION
Shorewood' s largest drainage area is included in this dis-
trict, which is totally within the city limits. It extends from
the southernmost border of Shorewood to Lake Minnetonka on the
' north. The district generally lies west of Eureka Road and east
of Howard' s Point Road. Total area is 810 acres, of which 100
acres are wetlands.
' TERRAIN
The highest location is at elevation 1000 in the southeast
' section. A large wetland area is located in the northwest por-
tion of this district at elevation 930 . Generally the terrain
slopes from the outside district borders towards these wetlands.
LAND USE
The southeast area of this district is zoned R-2 , single
family. The remaining portion is zoned R-1, single family
' (estate) .
EXISTING DRAINAGE SYSTEM - PLATE 13a
The existing drainage system generally flows overland and
through natural channels to the wetlands in the northwest. Cul-
verts in the natural drainage ways, which were field located,
' are indicated on the existing drainage map.
There are some drainage problems on the north side of the
' M. & St. L. railroad west of Stawberry Lane. A temporary ditch
has been considered to relieve flooding in this area. The ditch
' -58-
would follow the railroad and outlet into the natural channel
northeast of Strawberry Lane .
' LAKES AND PONDING AREAS
The wetlands area in the southeast will continue to be used
as a settlement basin with an overflow northwest to the large
' wetlands.
An inundation area is proposed on the south side of the
M. & St. L. railroad, northeast of Strawberry Lane, where the
existing natural channel crosses. This would allow a temporary
flooding to elevation 969 , providing 11 acre-feet of storage.
This 6 acre inundation area could be developed as a park site
' designed for occasional flooding. The outlet under the tracks
' would be reduced to an 18" culvert to hold back the runoff and
reduce the size of storm sewer pipe required downstream.
' This large wetlands outlets to Lake Minnetonka at its
northwest corner by a 24" culvert under Edgewood Road. A 24
hour 100 year storm could raise the water level a maximum 1-1/2
' feet from a normal elevation of 930 to a high water elevation of
931.5 in the wetlands.
PROPOSED DRAINAGE SYSTEM - PLATE 13b
Although storm sewer pipe have been designed for this dis-
trict, the overland channels should continue in use and could be
' incorporated into Shorewood' s greenway system.
The proposed drainage system includes storm sewer from the
wetlands west of Eureka Road northwest across the M. & St. L.
tracks to Grant Lorenz Road. Flow is then carried north on
-59-
1
Grant Lorenz Road and west to the large wetland area. This
' follows the existing natural drainage channel.
Proposed storm sewer trunk system in the central interior
' drainage area originates at the south border of Shorewood. This
trunk carries runoff north and then west where it discharges in-
!! to the large wetlands area. A portion of the flow in this trunk
is diverted from its existing drainage to the northeast follow-
ing the natural channel. This reduces the trunk storm sewer re-
quired for drainage to the same wetlands area and subsequently
the cost of the system.
The remaining storm sewer on the south and the west areas
of the district drain smaller areas directly into the wetlands.
On the north side of the district, along Edgewood Road, run-
off which is not directed into the wetlands by storm sewer will
continue to drain northward directly into Lake Minnetonka.
INTERCOMMUNITY PARTICIPATION
As this drainage district is entirely within the borders of
Shorewood, no intercommunity participation is required.

LAKE VIRGINIA DISTRICT
LOCATION
' The northern tip of Lake Virginia is located in the south-
west portion of the city of Shorewood. The majority of the lake,
as well as a large portion of the watershed, is in the city of
Victoria with some contributing area in Chanhassen.
The total area of Shorewood in the Lake Virginia District
is 135 acres. Of this total acreage, 4 acres are Lake Virginia
' and 21 acres are the Lake Virginia wetlands. Total water sur-
face area of Lake Virginia is approximately 110 acres . The con-
tributing area outside of Shorewood into Lake Virginia was not
determined.
' TERRAIN
11 The highest elevation in this district is approximately el-
evation 980 . The water surface elevation of Lake Virginia is
approximately elevation 930 . The land within this district gen-
erally slopes from the outside boundaries into Lake Virginia or
' its wetlands.
LAND USE
The land in this district is zoned R-1, single family
(estate) .
Designated wetlands areas are indicated on the drainage map
' for the district.
' EXISTING DRAINAGE SYSTEM - PLATE 14a
The existing drainage is overland into Shorewood' s wetlands
-61-
or into Lake Virginia. There is one low area in the south-
eastern portion of Shorewood which ponds contributing runoff.
Some existing culverts were field located and are indicated
on the existing drainage map.
LAKES AND PONDING AREAS
Lake Virginia is the only lake within this district.
Though a natural ordinary high water (N. O. H. W. ) has not been
established by the Department of Natural Resources, their recent
field investigations indicate an ordinary high water (0.H.W. ) of
929 .8 . The natural outlet is from the southwest corner of the
' lake by overflow creek to Smithtown Bay, Lake Minnetonka. No
analysis of the contributing area outside of Shorewood has been
made for this report.
As Smithtown Road and the existing homes are considerably
higher than Lake Virginia, no flooding problems are anticipated.
' Flood elevations should be established with Victoria for de-
ll velopment around the lake.
No other ponding areas are proposed in this district.
' PROPOSED DRAINAGE SYSTEM - PLATE 14b
Proposed storm sewer drains this district directly into the
Lake Virginia wetlands. Other than storm sewer on existing
streets, there is a proposed storm sewer extended east to drain
the low area.
-62-
I
INTERCOMMUNITY PARTICIPATION
This part of Shorewood can be storm sewered independently
' of Victoria. The only joint participation required between the
communities is the control of Lake Virginia and its outlet.

WEST DISTRICT
1
LOCATION
1 This district is located along the western portion of
' Shorewood' s main land. The western perimeter of this district
is bounded by Lake Minnetonka. There are 135 acres within this
district, which includes 6 acres of wetlands. For purposes of
this report, the south border of this district has been termina-
lted at Shorewood' s south boundary. This district could be ex-
tended into Victoria; however, the area which would thus be in-
cluded drains directly into Lake Minnetonka.
' TERRAIN
The highest elevations are approximately 1005 on the ridge
' through the center of the district which separates the area
' draining directly into Lake Minnetonka from the area which
drains into the interior wetlands. In general the land slopes
' towards Lake Minnetonka or towards the wetlands areas. Eleva-
tions of Lake Minnetonka and wetlands areas are approximately
' 930 .
' LAND USE
The land within this district is zoned R-1 single family
(estate) .
There are two small areas designated as wetlands.
' EXISTING DRAINAGE SYSTEM - PLATE 15a
Along the north and the west perimeters of this district,
drainage is directly into Lake Minnetonka. The remainder of the
i
-64-
I
1
area drains to the interior wetlands which outlet west to Lake
Minnetonka.
Existing drainage is overland, utilizing natural low areas
' for ponding. No major existing culverts were located by the
field survey.
LAKES AND PONDING AREAS
The two wetlands areas, of 5 acres and 1 acre, are utilized
as settlement basins prior to overflow west into Lake Minne-
tonka.
PROPOSED DRAINAGE SYSTEM - PLATE 15b
Proposed storm sewer is located on existing streets and on
easements along natural drainage lines. Storm sewer in the
' north portion of the district outlets into Lake Minnetonka.
' Storm sewer east of the interior district divide follows
the natural drainage pattern and discharges into the wetlands .
' The other storm line from north of this wetlands area diverts an
area which normally drains to Lake Minnetonka into the wetlands.
Other areas in this district continue to drain overland di-
rectly into Lake Minnetonka or into the wetlands.
INTERCOMMUNITY PARTICIPATION
' No storm sewer is proposed which would be common to Shore-
wood and Victoria.
