CITY OF CHANHASSEN
CARVER AND HENNEPIN COUNTIES, MINNESOTA
FINDINGS OF FACT
AND RECOMMENDATION
(APPROVAL)
The application of Gene and Lois Sipprell for the installation of a septic system within the
required bluff setback and impact zone on a property zoned A-2 - Planning Case 2018-17.
On September 18, 2018, the Chanhassen Planning Commission, acting as the Board of Appeals
and Adjustments, met at its regularly scheduled meeting to consider the application. The
Planning Commission conducted a public hearing on the proposed variance preceded by
published and mailed notice. The Board of Appeals and Adjustments makes the following:
FINDINGS OF FACT
1. The property is currently zoned Agricultural Estate District A-2.
2. The property is guided in the Chanhassen Comprehensive Plan for Residential Low Density.
3. The legal description of the property is:
The west 152.3 feet of the east 355.85 feet of the north 286.0 feet of the south 572 feet of the
Southeast Quarter of the Southeast Quarter (SE '/< of SE '/4) of Section 26, Township 116,
Range 23, Carver County, Minnesota.
4. Variance Findings — Section 20-58 of the City Code provides the following criteria for the
granting of a variance:
a. Variances shall only be permitted when they are in harmony with the general purposes
and intent of this Chapter and when the variances are consistent with the comprehensive
plan.
Finding: The intent of the city's bluff protection ordinance is to ensure that vegetation
and soils located near and on bluffs are not distributed in a manner that has the potential
to create erosive conditions or otherwise negatively impact the bluff. The city also
requires septic systems to be setback from property lines and road right of ways in order
to minimize the potential for these systems to negatively impact adjacent property owners
or interfere with the installation of utilities or other features commonly found in right of
ways. In this case, there are no adjacent residential properties and the street is a private
one, so the there is less concern for waiving the required property line setbacks. By
granting a variance to the property line setbacks, the required bluff setback variance is
minimized and the septic system can be placed further away from the more sensitive
portions of the bluff.
SCANNED
Granting a variance to allow a single-family home with no ability to hook up to
municipal utilities to install a septic system is consistent with the comprehensive plan,
and the proposed variance is in harmony with the intent of the zoning code.
b. When there are practical difficulties in complying with the zoning ordinance. "Practical
difficulties," as used in connection with the granting of a variance, means that the
property owner proposes to use the property in a reasonable manner not permitted by this
Chapter. Practical difficulties include, but are not limited to, inadequate access to direct
sunlight for solar energy systems.
Finding: Due to the existence of bluffs on the property, the dimensions of the property,
the placement of the house, nature of the contours, and characteristics of the soil, the
septic system must be placed in the northeast corner of the property. This placement
requires variances from the bluff setbacks, impact zone, and property line setbacks. City
sewer and water will not be available for the property in the near future and a functioning
septic system is required to have reasonable use of the property.
c. That the purpose of the variation is not based upon economic considerations alone.
Finding: The variance request is not solely based upon economic considerations.
d. The plight of the landowner is due to circumstances unique to the property not created by
the landowner.
Finding: The lot is a non -conforming lot of record that was created before the existing
district standards, bluff protection, and septic system ordinances were created.
e. The variance, if granted, will not alter the essential character of the locality.
Finding: Many components of the septic system would be located below grade and would
not be expected to have any visual impact on the neighborhood. The applicant intends to
install landscaping to minimize the visual impact of the above -grade portions of the system.
The surrounding residential properties are also located on large lots and are served by septic
systems.
f. Variances shall be granted for earth sheltered construction as defined in Minnesota
Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter.
Finding: This does not apply to this request.
5. The planning report #2018-17, dated September 18, 2018, prepared by MacKenzie Walters,
is incorporated herein.
RECOMMENDATION
"The Chanhassen Board of Appeals and Adjustments recommends that the City Council
approves the placement of the pump line within the 50 -foot bluff setback area and the 20 -foot
bluff impact zone, a 30 -foot bluff setback variance for the tanks and a 20 -foot bluff and 9 -foot
property line setback variance for the mounds and dispersal area, subject to the conditions of
approval:
1. The applicant must apply for and receive all necessary permits from the relevant
agencies.
2. The applicant shall work with city, county, and watershed staff to maximize the
system's distance from the bluff, minimize its impact on the bluff, and avoid
impacting the existing drainage swale.
3. The applicant shall minimize tree loss, and shall, to the greatest extent possible, avoid
removing mature trees within 20 feet of the top of the bluff.
4. A new I" = 20' scale survey showing the final location of the septic and pump tanks,
pump line, mound, and drain field shall be provided as part of the permitting process.
5. The area around the septic system mounds shall be landscaped so as to minimize its
visual impact."

CASE #: 2018-17
BY: MW
"The Chanhassen Planning Commission recommends that the City Council approve the
placement of the pump line within the 50 -foot bluff setback area and 20 -foot bluff impact zone,
a 30 -foot bluff setback variance for the tanks and a 20 -foot bluff and 9 -foot property line
setback variance for the mounds and dispersal area, subject to the conditions of approval and
adopts the attached Findings of Fact and Recommendation."
(Note: A motion for denial and appropriate findings of fact are also included at the end of the
report.)
SUMMARY OF REQUEST:
The applicant has an existing septic system that does not meet current standards and will need to
be replaced within the next two years. The applicant is requesting a variance to place a mound
septic system eight feet from the property lines and 15 feet from the top of the bluff, with new
tanks replacing the existing tanks 20 feet from the top of the bluff and a pump line within the
bluff setback and impact zone. The proposed septic system is being sized to accommodate the
possible addition of a sixth bedroom to the existing five -bedroom house. A variance is required
U_
cause Chapter 19 requires that septic
systems be setback 10 feet from property lines
and 50 feet from the top of the bluff, and
Chapter 20 prohibits the removal or alteration
of vegetation and grading within 20 feet from
the top of a bluff.

LEVEL OF CITY DISCRETION IN DECISION-MAKING:
The city's discretion in approving or denying a variance is limited to whether or not the proposed
project meets the standards in the Zoning Ordinance for a variance. The city has a relatively high
level of discretion with a variance because the applicant is seeking a deviation from established
standards. This is a quasi-judicial decision.
Notice of this public hearing has been mailed to all property owners within 500 feet-
PROPOSAL/SUMMARY
The applicants recently purchased this
property. During the purchasing process,
they were informed that the septic
system was inadequate and would need
to be replaced within the next two years.
They also wish to size the system to
accommodate a future sixth bedroom.
Their septic system installer informed
them that a double -mound system would
be required and that due to the location
of the house, well, and disturbed nature
of the soils near the house, the septic
system would need to be located within
the 50 -foot bluff setback.
The proposed septic system would be
approximately eight feet from the
property lines and 15 feet from the top of
the bluff, with tanks located 20 feet from
the top of the bluff. The pump line would
be within five feet of the top of the bluff
at its closest point.

The septic installer has stated that the
proposed tank and septic locations are required due to the location of the home's sewer line and
existing tanks. Similarly, the location of the pump line is dictated by the location of the tanks and
mound system. The installer is proposing locating the double -mound system in the northeast
comer of the lot to maximize its distance from the bluff, and because it is the only area of the
property that he believes has suitable contours and soils for the mounds. The installer has stated
that there is not sufficient space on the property to accommodate the septic system outside of the
50 -foot bluff setback.

The applicant has stated that the requested variance is necessary to address the deficiencies of
their existing septic system, and to allow for the addition of an additional bedroom on the
property.

BACKGROUND
County records indicate that the home was built in 1975.
On September 21, 1984, the city issued a permit for a 634 square foot addition.
On October 14, 1991, the city passed ordinance number 152, which created the city's bluff
protection ordinance.
On August 22, 1994, the city expanded the bluff protection ordinance to cover the entire city.
On December 14, 1998, the city passed ordinance number 286, which created the Bluff Creek
Overlay District.
On February 8, 1999, the city passed ordinance number 289, which governed the installation and
maintenance of septic systems and established a 20 -foot bluff setback.
On May 23, 2011, the city passed ordinance number 523, adopting Carver County Ordinance 67-
2010 by reference and establishing the current 50 -foot bluff setback for septic systems.

Planning Case #2018-17

SITE CONDITIONS
The property is zoned Agricultural Estate District (A-2) and contains a bluff. Portions of the site
are also located near the Bluff Creek Overlay District. This zoning district requires lots to be a
minimum of 2.5 acres, have front yard and rear setbacks of 50 feet, side yard setbacks of 10 feet,
and limits parcels to a maximum of 20 percent (20%) lot coverage. Structures are required to be
30 feet or the existing distance from the top of the bluff, with no topographic or vegetative
alterations permitted within 20 feet from the top of the bluff. Structures must also be setback 40
feet or the existing distance from the Bluff Creek primary zone and no site disturbances are
permitted within the first 20 feet or first 50 percent (50%) of existing setback from the primary
zone. Chapter 19 requires septic systems to be setback 50 feet from bluffs.
The lot is a non -conforming, 43,600 square feet lot. The existing structure meets the front, rear,
and side setbacks, with a deck encroaching approximately 10 feet into the 30 -foot bluff setback.
The house appears to meet the 40 -foot setback from the Bluff Creek primary zone. The existing
septic tanks are located approximately 20 feet from the top of the bluff.
NEIGHBORHOOD
Vogel Addition
The property is an unplated lot
near the Bluff Creek Golf Course
and Vogel Addition. The
property is accessed by
Creekwood Drive, a private road
serving the golf course and six
residential properties. All of the
residential properties are on
septic and well. Municipal
services are not expected to
become available in the near
future.
Variances within 500 feet:
1985-03 - 815 Creekwood Drive: Denied - Minimum lot size for subdivision to create a 3.56 -
acre lot and a I -acre lot; was subsequently litigated with settlement to create two lots with 2.28
acres each.
2010-05 - 845 Creekwood Drive: Approved - Retaining wall within bluff impact zone.

ANALYSIS
Septic and Pump Tanks
The applicant is proposing placing the
septic and pump tanks behind the house,
20 feet from the top of the bluff. The
applicant has stated that this location is
necessitated by the placement of the
home's existing sewer line and the
elevation of the sewer pipe. The existing
tanks are also located in this area.
The r dl I
A'
/4,0 r,
I'
I If
� ,sa' � 1>'•

V o11 ocanon rs an a ready
disturbed area of the site that would need to be further disturbed to fill the existing tanks. It is also
outside of the 20 -foot Bluff Creek primary zone do not disturb area and 20 -foot bluff impact zone.
Staff believes that the proposed location for this portion of the system is reasonable and should not
significantly impact the bluff.
For these reasons, staff recommends approval of the 30 -foot bluff setback variance for the septic
and pump tanks.
Pump Line
The applicant's proposed location for the pump line is determined
by the locations of the pump tank and the mound. The applicant has
stated that physical features of the property prevent any alternative
placement of the pump line.
As the applicant has noted, the ultimate location of the pump line
will be determined by the location of the tanks and the mound
system. Since the location of the tanks is predetermined by the
home's sewer line and the pump line's exit from the pump tank is
dictated by the location of the house and deck, the location of this
feature cannot be significantly altered. Since the pipe is entirely
below ground, staff's largest concern would be the removal of
Line
vegetation, especially mature trees that would accompany its installation. The proposed location
mostly avoids the woods, and staff encourages the applicant to take all possible steps to minimize
tree loss associated with its installation. Staff believes that the proposed location of this portion of
the system is necessary, and cannot be significantly improved upon.
For these reasons, staff recommends approval of the variance from the 50 -foot bluff setback and 20 -
foot bluff impact zone for the pump line.
821 Creekwood Drive
Planning Case #2018-17

Mound System
The applicant has stated that the proposed location for the mound
system, shown in green, is necessary due to the contours of the
property. They have stated that state code requires a mound septic to be
set on a contour for the length of its rock bed and that this consideration
requires the double -mound system as well as the proposed placements
of both mounds and their drain fields. The applicant's installer has
indicated a strong preference for placing a mound system on an area
with at least a 1-2% slope.
Staff asked the applicant to address the possibility of installing a Type
III septic system. The applicant's installer has indicated that the
presence of disturbed soils in the middle of the yard makes it difficult
to be certain that an installed system would perform adequately in that
area. They have stated that disturbed soils, such as appear to be present
in that area, have a higher chance of failing to accept effluent long
term, of undertreating effluent, and of discharging untreated effluent.
They note that the best soils with sufficient slope and contours are
always the best choice for locating a septic system.
In reviewing the proposed location for the double -mound system, staff was very concerned to notice
that it is adjacent to a swale that handles a large amount of stormwater runoff from Bluff Creek Golf
Course and directly discharges into Bluff Creek, a state classified impaired water. Staff also
observed that a large head cut is present in this area and that it is actively eroding the bluff directly
downstream from the proposed location. For these reasons, Water Resources is recommending
denial of the variance request unless it can be demonstrated that no other location or system is
feasible.
Staff consulted with Carver County's Soil and
Water Conservation District's Conservation
Technician, Chip Hentges, regarding the
proposed location of the double -mound
portion of the system. He indicated that the
largest concern from the County's perspective
was that the proposed mound system stay clear
of the drainage Swale located near the 928
contour. It is Conservation Technician
Hentges' opinion that by grating 1 -foot lot line
setbacks it should be possible to shift the
system to the southeast so that the toe of the
southern mound's sand is clear of the 30 -foot
bluff setback indicated on the survey.

He also notes that the rock bed locations should be able to work in their proposed areas.
Building Inspector Tessman also reviewed the proposed septic system's location and design. He
recommends that the mounds be pushed forward to within 1 foot of the property line and that the
mound ratio be changed from 3:1 to 4:1. Both of these modifications would increase the distance
from the toe of the proposed mound system to the top of the bluff.
Based on these reviews and the importance of protecting Bluff Creek, staff is recommending that a
20 -foot bluff and 9 -foot property line setback variance be given for the mound portion of the
system, rather than the 35 -foot bluff and 2 -foot property line setback variance the applicant is
requesting.
Impact on Neighborhood
The largest impact on the neighborhood will be the loss of the
wooded area in the northeast of the property. Most of the
surrounding properties have heavily wooded yards; however,
several other properties do have mostly open front yards.
Many components of the septic system would be located
below grade and would not be expected to have any visual
impact on the neighborhood. The applicant intends to install
landscaping to minimize the visual impact of the above -grade
portions of the system.
SUMMARY
Staff believes that a variance is necessary to accommodate a new septic system; however, the bluff
is already beginning to head cut and the removal of vegetation, disruption of soil, and other
elements involved with septic systems could exacerbate the existing erosive issues. Staff believes
that the septic system's design and location can be adjusted to provide for an increased distance
between portions of the septic system and the bluff. Staff recommends that a modified version of the
proposed variance, which allows the septic system to be located closer to the property lines but
requires a larger bluff setback than the applicant is requesting, be approved.
RECOMMENDATION
Staff recommends that the Chanhassen Planning Commission recommend that the City Council
approve the placement of the pump line within the 50 -foot bluff setback area and 20 -foot bluff
impact zone, a 30 -foot bluff setback variance for the tanks and a 20 -foot bluff and 9 -foot
property line setback variance for the mounds and dispersal area, subject to the conditions of
approval and adopt the attached Findings of Fact and Recommendation:
The applicant must apply for and receive all necessary permits from the relevant
agencies.

CARVER AND HENNEPIN COUNTIES, MINNESOTA
FINDINGS OF FACT
AND RECOMMENDATION
(APPROVAL)
IN RE:
The application of Gene and Lois Sipprell for the installation of a septic system within the
required bluff setback and impact zone on a property zoned A-2 - Planning Case 2018-17.
On September 18, 2018, the Chanhassen Planning Commission, acting as the Board of Appeals
and Adjustments, met at its regularly scheduled meeting to consider the application. The
Planning Commission conducted a public hearing on the proposed variance preceded by
published and mailed notice. The Board of Appeals and Adjustments makes the following:
FINDINGS OF FACT
1. The property is currently zoned Agricultural Estate District A-2.
2. The property is guided in the Chanhassen Comprehensive Plan for Residential Low Density.
3. The legal description of the property is:
The west 152.3 feet of the east 355.85 feet of the north 286.0 feet of the south 572 feet of the
Southeast Quarter of the Southeast Quarter (SE'/, of SE 'h) of Section 26, Township 116,
Range 23, Carver County, Minnesota.
4. Variance Findings —Section 20-58 of the City Code provides the following criteria for the
granting of a variance:
a. Variances shall only be permitted when they are in harmony with the general purposes
and intent of this Chapter and when the variances are consistent with the comprehensive
plan.
Finding: The intent of the city's bluff protection ordinance is to ensure that vegetation
and soils located near and on bluffs are not distributed in a manner that has the potential
to create erosive conditions or otherwise negatively impact the bluff. The city also
requires septic systems to be setback from property lines and road right of ways in order
to minimize the potential for these systems to negatively impact adjacent property owners
or interfere with the installation of utilities or other features commonly found in right of
ways. In this case, there are no adjacent residential properties and the street is a private
one, so the there is less concern for waiving the required property line setbacks. By
granting a variance to the property line setbacks, the required bluff setback variance is
minimized and the septic system can be placed further away from the more sensitive
portions of the bluff.
Granting a variance to allow a single-family home with no ability to hook up to
municipal utilities to install a septic system is consistent with the comprehensive plan,
and the proposed variance is in harmony with the intent of the zoning code.
b. When there are practical difficulties in complying with the zoning ordinance. "Practical
difficulties," as used in connection with the granting of a variance, means that the
property owner proposes to use the property in a reasonable manner not permitted by this
Chapter. Practical difficulties include, but are not limited to, inadequate access to direct
sunlight for solar energy systems.
Finding: Due to the existence of bluffs on the property, the dimensions of the property,
the placement of the house, nature of the contours, and characteristics of the soil, the
septic system must be placed in the northeast comer of the property. This placement
requires variances from the bluff setbacks, impact zone, and property line setbacks. City
sewer and water will not be available for the property in the near future and a functioning
septic system is required to have reasonable use of the property.
c. That the purpose of the variation is not based upon economic considerations alone.
Finding: The variance request is not solely based upon economic considerations.
d. The plight of the landowner is due to circumstances unique to the property not created by
the landowner.
Finding: The lot is a non -conforming lot of record that was created before the existing
district standards, bluff protection, and septic system ordinances were created.
e. The variance, if granted, will not alter the essential character of the locality.
Finding: Many components of the septic system would be located below grade and would
not be expected to have any visual impact on the neighborhood The applicant intends to
install landscaping to minimize the visual impact of the above -grade portions of the system.
The surrounding residential properties are also located on large lots and are served by septic
systems.
f. Variances shall be granted for earth sheltered construction as defined in Minnesota
Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter.
Finding: This does not apply to this request.
5. The planning report #2018-17, dated September 18, 2018, prepared by MacKenzie Walters,
is incorporated herein.
RECOMMENDATION
"The Chanhassen Board of Appeals and Adjustments recommends that the City Council
approves the placement of the pump line within the 50 -foot bluff setback area and the 20 -foot
bluff impact zone, a 30 -foot bluff setback variance for the tanks and a 20 -foot bluff and 9 -foot
property line setback variance for the mounds and dispersal area, subject to the conditions of
approval:
1. The applicant must apply for and receive all necessary permits from the relevant
agencies.
2. The applicant shall work with city, county, and watershed staff to maximize the
system's distance from the bluff, minimize its impact on the bluff, and avoid
impacting the existing drainage swale.
3. The applicant shall minimize tree loss, and shall, to the greatest extent possible, avoid
removing mature trees within 20 feet of the top of the bluff.
4. A new 1" = 20' scale survey showing the final location of the septic and pump tanks,
pump line, mound, and drain field shall be provided as part of the permitting process.
5. The area around the septic system mounds shall be landscaped so as to minimize its
visual impact."

The west 152.3 feet of the east 355.85 feet of the north 286.0 feet of the south 572 feet of the
Southeast Quarter of the Southeast Quarter (SE '/< of SE 1/4) of Section 26, Township 116,
Range 23, Carver County, Minnesota.
4. Variance Findings — Section 20-58 of the City Code provides the following criteria for the
granting of a variance:
a. Variances shall only be permitted when they are in harmony with the general purposes
and intent of this Chapter and when the variances are consistent with the comprehensive
plan.
Finding: The intent of the city's bluff protection ordinance is to ensure that vegetation
and soils located near and on bluffs are not distributed in a manner that has the potential
to create erosive conditions or otherwise negatively impact the bluff. The bluff near the
proposed location for the septic system is already subject to a large amount of runoff that
has created a head cut which is actively eroding the bluff downstream from the proposed
location. Furthermore, runoff from this area directly discharges into Bluff Creek, a state
classified impaired water. It would not be in line with the intent of this Chapter to allow
the removal of vegetation and disruption of soils that could exacerbate these issues.
b. When there are practical difficulties in complying with the zoning ordinance. "Practical
difficulties," as used in connection with the granting of a variance, means that the
property owner proposes to use the property in a reasonable manner not permitted by this
Chapter. Practical difficulties include, but are not limited to, inadequate access to direct
sunlight for solar energy systems.
Finding: A type Ill septic system could be installed in the flat portion of the yard away
from the top of the bluff. Since there is an alternative location for a septic system that
meets city code, the applicant does not have a practical difficulty.
c. That the purpose of the variation is not based upon economic considerations alone.
Finding: The variance request is not solely based upon economic considerations.
d. The plight of the landowner is due to circumstances unique to the property not created by
the landowner.
Finding: The lot is a non -conforming lot of record that was created before the existing
district standards, bluff protection, and septic system ordinances were created.
e. The variance, if granted, will not alter the essential character of the locality.
Finding: The area where the applicant is proposing to install the septic system is heavily
wooded and many mature trees would need to be removed. Most of the residential homes
in the vicinity are setback within existing woods; removing these trees would noticeably
alter the character of the neighborhood.
f. Variances shall be granted for earth sheltered construction as defined in Minnesota
Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter.
Finding: This does not apply to this request.
5. The planning report #2018-17, dated September 18, 2018, prepared by MacKenzie Walters,
is incorporated herein.
RECOMMENDATION
"The Chanhassen Board of Appeals and Adjustments recommends that the City Council
deny the variance request to place a pump line within the bluff setback and impact zone, the 30 -
foot bluff setback variance for the tanks, and the 35 -foot bluff setback variance and 2 -foot
property line setback variance for the mound system."

The Narrative for the 821 Creekwood Drive, Chaska, MN 55318
(Mailing Address)
Submitted by homeowners: Gene and Lowie Sipprell
August 20, 2018
On May 29, 2018, we purchased 821 Creekwood Drive as our primary residence. As
part of the process we requested that the lot be surveyed, septic and water systems
be tested. The results indicated the septic system was found to be inadequate to
current standards and would need to be replaced within two years. As we inquired
into this process we learned if we ever wanted to add another bedroom we would
need to have a double mound system. We consulted septic system installer Dale
Denn of Homestead Septic before the purchase of the home. He drew up two or
three different double -mound systems providing a way for water movement across
the property.
In June, 2018, we met with the city representatives at the proposed new site for the
septic system. They advised that the only location for a double mound system
would be in the far north eastern corner of our lot and a variance would be needed
to address the requirement setback to be 50 feet from the bluff.
July, 2018, Sathr-Berquist, Inc of Wayzata completed two surveys: surface lot and
bluff elevation. (See previously submitted documents)
August, 2018, we met with the neighbors including Michael Cohrs, General
Manager/Course Superintendent of Bluff Creek Golf course that adjoins our
property. They are supportive of installing the new septic system. Our realtor, Rick
Brama has advised us on a landscaper who could provide us with a beautiful design.
Consequently, we are confident that we can install the required septic system and a
beautiful landscaping area that will enhance our neighborhood.
We look forward to answering any questions the city may have and moving forward
so we can complete the septic system installation and landscaping this Fall.
Thank you for your assistance.
Sincerely,
Rev. Dr. Gene Sipprell

Septic System Variance:
Property: 821 Creekwood Drive
Chaska, MN 55318
A variance is needed that is within the 50 foot bluff setback ordinance.
In general, there are three situations whereby components of the new Mound Septic System will
be within 50 feet of the Bluff:
1. Septic and Pump Tanks
2. Pump line from pump tank to the Mound
3. The Mound
The reasons for the variances is as follows:
1. Septic and Pump tanks have to be where they are as that is where the old tanks are thus
the sewer line from the home comes out in that vicinity and the elevation of the sewer
pipe dictates where tanks need to go.
2. The pump line from the pump tank thus has to start at the pump tank location and
continue to the Mound. Physical features disallow any options to where the pump line
can be run.
3. The Mound has been located where it is due to the fact that the soils in this area are un-
disturbed, verses somewhat disturbed soils in the lawn area from initial construction. I
know that large trees indicate the most natural soils. Secondly, the contours are ever so
slightly undulating outside of where I set the Mound that is it difficult to set a Mound on
a definite contour to meet the Septic Ordinance. Lastly, if all of the Mound has to be
outside of the 50 foot bluff setback, there literally is not enough room to place any part of
the septic system.

For new construction lots, all septic sites shall be protected in the field with fencing/identification up to
the time of installation. Existing home lots, do not disturb septic site and keep all heavy equipment and
vehicles off of the site. Any trees that need removal must be done without rubber tired equipment, ie,
track machines to avoid soil compaction and undue disturbance. Cut tree trucks as close to surface as
possible and leave stumps intact, do not excavate. Grinding is ok with a portable grinder.
Contact Dale Denn with any questions, comments, or concerns about this Septic Site.
This Cover Page with Designer Signature, electronic or otherwise, hereby certifies that I have
completed this septic design in accordance with all applicable State Septic Rules. Local rules may
vary from State Rules. Installer to verify all aspects of applicable Local Rules and setbacks that may

♦
System is for a 6 bedroom Home. Soils only accommodate a Pressurized Mound Septic. Mound is
+
♦
split into two equal units on account of slope, short contours, drainage Swale, and bluff line.
♦
Each Mound halve will have the sandbed and laterals at the same elevation based on sandbed
elevation of Unit 1. End feed from pump each unit, essentially center feeding Mound as single unit.
+
Finish Mound as one unit and build saddle to divert all rain and snow melt.
+
Pump station is designed for a dual pump arrangement with an alternating dose panel. Each
+
Mound half will have its own pump and be controlled by the dosing panel. Use either a dual
+
<•
pump line, one for each mound half, or a single pump line with Check Valves properly installed
♦
off of each pump. Calculate flow for each pump based on one half of total flow plus drainback.
+
See design and pump pages.

Response to supplement Variance request:
There are not two different septic locations. Please see the design or the drawing page
that is attached to this letter. The Mound has to be split into two equal parts due to the
nature of the contours on the property. A Mound Septic has to be set on a contour for the
full length of its rockbed according to Minnesota 7080 Code. The contours in this case
are not continuous enough to site the full length of the rockbed. Thus there are two parts,
not two sites.
2. Furthermore, based on contours alone and the nature of the contours indicated above, it is
not feasible to simply begin to move, shift or slide the system anywhere from where it is
now sited. I spend time with the laser level establishing contours initially and they just
where not very conducive to set a full length Mound practically anywhere on the site.
The contours, and the slope, another important and code aspect of designing a septic,
both work best where the Mound is now designed. Out in the lawn area towards the
home, the contours are short, and become nonlinear, and the slope drops to nearly zero.
In other words, slightly undulating in different directions making it difficult to set a
Mound with the highest level of confidence in longevity. Zero slope meets the code, but
it is riskier to place as Mound on zero percent slope that is slightly undulating because the
effluent is more difficult to evaluate where it will go and pond and soak up. A definitive
slope defines clearly the direction of effluent flow. I always try to avoid siting a Mound
on slope less than 1-2%.
3. Thirdly, it
to have a
septic system verses a standard type I. Going out into the lawn towards the home has
soils that have some indication of disturbance, most likely from the home building
Process. This disturbance can include mixing of soils, addition fill soil spread over
natural soil, soil compaction, slow percolation, all of which become much less suitable
for the performance of a septic system of almost any sort. A few soil samples cannot tell
the whole story with soils that have been altered or impacted by construction activity.
The may not accept effluent over a long time, the effluent may not be treated as
effectively as a soil with its natural properties of texture and structure, and the effluent
may hit compacted layers and move laterally and potentially discharge at some point
being untreated septic effluent. Disturbed soils are much higher risk of failing to take
effluent and failing to treat effluent. The best soils with sufficient slope and contours are
always the best choice in protecting the environment and protecting public health and
safety.

MacKenzie,
Per Krista, Water Resource comments are as follows:
I would recommend denial, as there are some significant stormwater concerns that would very likely be
made worse by the proposed location of the system. It's my understanding after talking with Eric and
Chip, and meeting on site, that there is an alternative location and system that is feasible. I would like
the applicant at the very least to provide an argument as to why an alternative location and system
could not be used.
Concerns are as follows:
• The current proposed location is directly adjacent to a swale that is taking a large amount of
stormwater runoff from the Golf Course and directly discharging into Bluff Creek, which is classified as
an impaired water by the state, and currently under a TMDL.
• There is a large head cut, which is already actively eroding the bluff directly downstream from
the proposed location.
Mackenzie, do you mind sending an electronic copy of the proposed plan to Terry and Chip if you have it
(cc'd). I would like their comments included as well.

MacKenzie,
My recommendation would be to push the mound placement towards the front yard setback (toe of
mound slope to within 1 foot of the front yard setback) which would increase the distance of the mound
from the bluff setback. I would also recommend the mound ratio be changed from 3:1 to 4:1, which
would also increase the distance between the toe of the mound to the bluff setback.
Thank you,
Ag't

The lot has a number of existing mature trees covering the bluff, setback area and up into the
yard. All of the proposed septic locations are sited within the wooded areas of the lot and close
to or within the bluff setback. Removing mature trees at the top of the bluff exposes the area to
potential erosion issues. Staff recommends that sites outside of the bluff setback that remove as
few trees as possible are the preferred locations for a septic system.

PROPOSED MOTION:
"The Chanhassen Planning Commission recommends that the City Council approve the
placement of the pump line within the 50 -foot bluff setback area and 20 -foot bluff impact zone,
a 30 -foot bluff setback variance for the tanks and a 20 -foot bluff and 9 -foot property line
setback variance for the mounds and dispersal area, subject to the conditions of approval and
adopts the attached Findings of Fact and Recommendation."
(Note: A motion for denial and appropriate findings of fact are also included at the end of the
report.)
SUMMARY OF REQUEST:
The applicant has an existing septic system that does not meet current standards and will need to
be replaced within the next two years. The applicant is requesting a variance to place a mound
septic system eight feet from the property lines and 15 feet from the top of the bluff, with new
tanks replacing the existing tanks 20 feet from the top of the bluff and a pump line within the
bluff setback and impact zone. The proposed septic system is being sized to accommodate the
possible addition of a sixth bedroom to the existing five -bedroom house. A variance is required
because Chapter 19 requires that septic
systems be setback 10 feet from property lines
and 50 feet from the top of the bluff, and
Chapter 20 prohibits the removal or alteration
of vegetation and grading within 20 feet from
the top of a bluff.

LEVEL OF CITY DISCRETION IN DECISION-MAKING:
The city's discretion in approving or denying a variance is limited to whether or not the proposed
project meets the standards in the Zoning Ordinance for a variance. The city has a relatively high
level of discretion with a variance because the applicant is seeking a deviation from established
standards. This is a quasi-judicial decision.
Notice of this public hearing has been mailed to all property owners within 500 feet.
PROPOSAL/SUMMARY
The applicants recently purchased this
property. During the purchasing process,
they were informed that the septic
system was inadequate and would need
to be replaced within the next two years.
They also wish to size the system to
accommodate a future sixth bedroom.
Their septic system installer informed
them that a double -mound system would
be required and that due to the location
of the house, well, and disturbed nature
of the soils near the house, the septic
system would need to be located within
the 50 -foot bluff setback.
The proposed septic system would be
approximately eight feet from the
property lines and 15 feet from the top of
the bluff, with tanks located 20 feet from
the top of the bluff. The pump line would
be within five feet of the top of the bluff
at its closest point.
The septic installer has stated that the
proposed tank and septic locations are required due to the location of the home's sewer line and
existing tanks. Similarly, the location of the pump line is dictated by the location of the tanks and
mound system. The installer is proposing locating the double -mound system in the northeast
comer of the lot to maximize its distance from the bluff, and because it is the only area of the
property that he believes has suitable contours and soils for the mounds. The installer has stated
that there is not sufficient space on the property to accommodate the septic system outside of the
50 -foot bluff setback.

The applicant has stated that the requested variance is necessary to address the deficiencies of
their existing septic system, and to allow for the addition of an additional bedroom on the
property.

Note: Most of the applicable setback standards are located in Chapter 19; however, Chapter 19
does not have a specific variance procedure so the variance is being granted from the general
zoning code using the procedure outlined in Chapter 20.
County records indicate that the home was built in 1975.
On September 21, 1984, the city issued a permit for a 634 square foot addition.
On October 14, 1991, the city passed ordinance number 152, which created the city's bluff
protection ordinance.
On August 22, 1994, the city expanded the bluff protection ordinance to cover the entire city.
On December 14, 1998, the city passed ordinance number 286, which created the Bluff Creek
Overlay District.
On February 8, 1999, the city passed ordinance number 289, which governed the installation and
maintenance of septic systems and established a 20 -foot bluff setback.
On May 23, 2011, the city passed ordinance number 523, adopting Carver County Ordinance 67-
2010 by reference and establishing the current 50 -foot bluff setback for septic systems.

SITE CONDITIONS
The property is zoned Agricultural Estate District (A-2) and contains a bluff. Portions of the site
are also located near the Bluff Creek Overlay District. This zoning district requires lots to be a
minimum of 2.5 acres, have front yard and rear setbacks of 50 feet, side yard setbacks of 10 feet,
and limits parcels to a maximum of 20 percent (20%) lot coverage. Structures are required to be
30 feet or the existing distance from the top of the bluff, with no topographic or vegetative
alterations permitted within 20 feet from the top of the bluff. Structures must also be setback 40
feet or the existing distance from the Bluff Creek primary zone and no site disturbances are
permitted within the first 20 feet or first 50 percent (50%) of existing setback from the primary
zone. Chapter 19 requires septic systems to be setback 50 feet from bluffs.
The lot is a non -conforming, 43,600 square feet lot. The existing structure meets the front, rear,
and side setbacks, with a deck encroaching approximately 10 feet into the 30 -foot bluff setback.
The house appears to meet the 40 -foot setback from the Bluff Creek primary zone. The existing
septic tanks are located approximately 20 feet from the top of the bluff.
NEIGHBORHOOD
Vogel Addition
The property is an unplated lot
near the Bluff Creek Golf Course
and Vogel Addition. The
property is accessed by
Creekwood Drive, a private road
serving the golf course and six
residential properties. All of the
residential properties are on
septic and well. Municipal
services are not expected to
become available in the near
future.
Variances within 500 feet:
1985-03 - 815 Creekwood Drive: Denied - Minimum lot size for subdivision to create a 3.56 -
acre lot and a 1 -acre lot; was subsequently litigated with settlement to create two lots with 2.28
acres each.
2010-05 - 845 Creekwood Drive: Approved - Retaining wall within bluff impact zone.

ANALYSIS
Septic and Pump Tanks
The applicant is proposing placing the
septic and pump tanks behind the house.
20 feet from the top of the bluff. The
applicant has stated that this location is
necessitated by the placement of the
home's existing sewer line and the
elevation of the sewer pipe. The existing
tanks are also located in this area.
Th �
e propos location s an already
disturbed area of the site that would need to be further disturbed to fill the existing tanks. It is also
outside of the 20 -foot Bluff Creek primary zone do not disturb area and 20 -foot bluff impact zone.
Staff believes that the proposed location for this portion of the system is reasonable and should not
significantly impact the bluff.
For these reasons, staff recommends approval of the 30 -foot bluff setback variance for the septic
and pump tanks.
Pump Line
The applicant's proposed location for the pump line is determined
by the locations of the pump tank and the mound. The applicant has
stated that physical features of the property prevent any alternative
placement of the pump line.
As the applicant has noted, the ultimate location of the pump line
will be determined by the location of the tanks and the mound
system. Since the location of the tanks is predetermined by the
home's sewer line and the pump line's exit from the pump tank is
dictated by the location of the house and deck, the location of this
feature cannot be significantly altered. Since the pipe is entirely
below ground, staffs largest concern would be the removal of
vegetation, especially mature trees that would accompany its installation. The proposed location
mostly avoids the woods, and staff encourages the applicant to take all possible steps to minimize
tree loss associated with its installation. Staff believes that the proposed location of this portion of
the system is necessary, and cannot be significantly improved upon.
For these reasons, staff recommends approval of the variance from the 50 -foot bluff setback and 20 -
foot bluff impact zone for the pump line.
821 Creekwood Drive
Planning Case #2018-17
Page 6
Mound System
The applicant has stated that the proposed location for the mound
system, shown in green, is necessary due to the contours of the
property. They have stated that state code requires a mound septic to be
set on a contour for the length of its rock bed and that this consideration
requires the double -mound system as well as the proposed placements
of both mounds and their drain fields. The applicant's installer has
indicated a strong preference for placing a mound system on an area
with at least a 1-2% slope.
Staff asked the applicant to address the possibility of installing a Type
III septic system. The applicant's installer has indicated that the
presence of disturbed soils in the middle of the yard makes it difficult
to be certain that an installed system would perform adequately in that
area. They have stated that disturbed soils, such as appear to be present
in that area, have a higher chance of failing to accept effluent long
term, of undertreating effluent, and of discharging untreated effluent.
They note that the best soils with sufficient slope and contours are
always the best choice for locating a septic system.
In reviewing the proposed location for the double -mound system, staff was very concerned to notice
that it is adjacent to a swale that handles a large amount of stormwater runoff from Bluff Creek Golf
Course and directly discharges into Bluff Creek, a state classified impaired water. Staff also
observed that a large head cut is present in this area and that it is actively eroding the bluff directly
downstream from the proposed location. For these reasons, Water Resources is recommending
denial of the variance request unless it can be demonstrated that no other location or system is
feasible.
Staff consulted with Carver County's Soil and
Water Conservation District's Conservation
Technician, Chip Hentges, regarding the
proposed location of the double -mound
portion of the system. He indicated that the
largest concern from the County's perspective
was that the proposed mound system stay clear
of the drainage swale located near the 928
contour. It is Conservation Technician
Hentges' opinion that by gating I -foot lot line
setbacks it should be possible to shift the
system to the southeast so that the toe of the
southern mound's sand is clear of the 30 -foot
bluff setback indicated on the survey.

He also notes that the rock bed locations should be able to work in their proposed areas.
Building Inspector Tessman also reviewed the proposed septic system's location and design. He
recommends that the mounds be pushed forward to within 1 foot of the property line and that the
mound ratio be changed from 3:1 to 4:1. Both of these modifications would increase the distance
from the toe of the proposed mound system to the top of the bluff.
Based on these reviews and the importance of protecting Bluff Creek, staff is recommending that a
20 -foot bluff and 9 -foot property line setback variance be given for the mound portion of the
system, rather than the 35 -foot bluff and 2 -foot property line setback variance the applicant is
requesting.
Impact on Neighborhood
The largest impact on the neighborhood will be the loss of the
wooded area in the northeast of the property. Most of the
surrounding properties have heavily wooded yards; however,
several other properties do have mostly open front yards.
Many components of the septic system would be located
below grade and would not be expected to have any visual
impact on the neighborhood. The applicant intends to install
landscaping to minimize the visual impact of the above -grade
portions of the system.
SUMMARY
Staff believes that a variance is necessary to accommodate a new septic system; however, the bluff
is already beginning to head cut and the removal of vegetation, disruption of soil, and other
elements involved with septic systems could exacerbate the existing erosive issues. Staff believes
that the septic system's design and location can be adjusted to provide for an increased distance
between portions of the septic system and the bluff. Staff recommends that a modified version of the
proposed variance, which allows the septic system to be located closer to the property lines but
requires a larger bluff setback than the applicant is requesting, be approved.
RECOMMENDATION
Staff recommends that the Chanhassen Planning Commission recommend that the City Council
approve the placement of the pump line within the 50 -foot bluff setback area and 20 -foot bluff
impact zone, a 30 -foot bluff setback variance for the tanks and a 20 -foot bluff and 9 -foot
property line setback variance for the mounds and dispersal area, subject to the conditions of
approval and adopt the attached Findings of Fact and Recommendation:
1. The applicant must apply for and receive all necessary permits from the relevant
agencies.
821 Creekwood Drive
Planning Case #2018-17
Page 8
2. The applicant shall work with city, county, and watershed staff to maximize the
system's distance from the bluff, minimize its impact on the bluff, and avoid
impacting the existing drainage swale.
3. The applicant shall minimize tree loss, and shall, to the greatest extent possible, avoid
removing mature trees within 20 feet of the top of the bluff.
4. A new 1" = 20' scale survey showing the final location of the septic and pump tanks,
pump line, mound, and drain field shall be provided as part of the permitting process.
5. The area around the septic system mounds shall be landscaped so as to minimize its
visual impact.
Should the Planning Commission recommend denying the variance request, it is recommended
that the Planning Commission adopt the following motion and attached Findings of Fact and
Decision:
"The Chanhassen Board of Appeals and Adjustments recommends that the City Council deny the
variance request to place a pump line within the bluff setback and impact zone, the 30 -foot bluff
setback variance for the tanks, and the 35 -foot bluff setback variance and the 2 -foot property line
setback variance for the mound system, and adopts the attached Findings of Fact and Decision"

FINDINGS OF FACT
AND RECOMMENDATION
(DENIAL)
"MMA
The application of Gene and Lois Sipprell for the installation of a septic system within the
required bluff setback and impact zone on a property zoned A-2 - Planning Case 2018-17.
On September 18, 2018, the Chanhassen Planning Commission, acting as the Board of Appeals
and Adjustments, met at its regularly scheduled meeting to consider the application. The
Planning Commission conducted a public hearing on the proposed variance preceded by
published and mailed notice. The Board of Appeals and Adjustments makes the following:
FINDINGS OF FACT
1. The property is currently zoned Agricultural Estate District A-2.
2. The property is guided in the Chanhassen Comprehensive Plan for Residential Low Density.
3. The legal description of the property is:
The west 152.3 feet of the east 355.85 feet of the north 286.0 feet of the south 572 feet of the
Southeast Quarter of the Southeast Quarter (SE '/+ of SE '/4) of Section 26, Township 116,
Range 23, Carver County, Minnesota
4. Variance Findings — Section 20-58 of the City Code provides the following criteria for the
granting of a variance:
a. Variances shall only be permitted when they are in harmony with the general purposes
and intent of this Chapter and when the variances are consistent with the comprehensive
plan.
Finding: The intent of the city's bluff protection ordinance is to ensure that vegetation
and soils located near and on bluffs are not distributed in a manner that has the potential
to create erosive conditions or otherwise negatively impact the bluff. The bluff near the
proposed location for the septic system is already subject to a large amount of runoff that
has created a head cut which is actively eroding the bluff downstream from the proposed
location. Furthermore, runoff from this area directly discharges into Bluff Creek, a state
classified impaired water. It would not be in line with the intent of this Chapter to allow
the removal of vegetation and disruption of soils that could exacerbate these issues.
b. When there are practical difficulties in complying with the zoning ordinance. "Practical
difficulties," as used in connection with the granting of a variance, means that the
property owner proposes to use the property in a reasonable manner not permitted by this
Chapter. Practical difficulties include, but are not limited to, inadequate access to direct
sunlight for solar energy systems.
Finding: A type III septic system could be installed in the flat portion of the yard away
from the top of the bluff. Since there is an alternative location for a septic system that
meets city code, the applicant does not have a practical difficulty.
c. That the purpose of the variation is not based upon economic considerations alone.
Finding: The variance request is not solely based upon economic considerations.
d. The plight of the landowner is due to circumstances unique to the property not created by
the landowner.
Finding: The lot is a non -conforming lot of record that was created before the existing
district standards, bluff protection, and septic system ordinances were created.
e. The variance, if granted, will not alter the essential character of the locality.
Finding: The area where the applicant is proposing to install the septic system is heavily
wooded and many mature trees would need to be removed. Most of the residential homes
in the vicinity are setback within existing woods; removing these trees would noticeably
alter the character of the neighborhood.
f. Variances shall be granted for earth sheltered construction as defined in Minnesota
Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter.
Finding: This does not apply to this request.
5. The planning report #2018-17, dated September 18, 2018, prepared by MacKenzie Walters,
is incorporated herein.
RECOMMENDATION
"The Chanhassen Board of Appeals and Adjustments recommends that the City Council
deny the variance request to place a pump line within the bluff setback and impact zone, the 30 -
foot bluff setback variance for the tanks, and the 35 -foot bluff setback variance and 2 -foot
property line setback variance for the mound system."
ADOPTED by the Chanhassen Planning Commission this 18th day of September, 2018.

Response to supplement Variance request:
There are not two different septic locations. Please see the design or the drawing page
that is attached to this letter. The Mound has to be split into two equal parts due to the
nature of the contours on the property. A Mound Septic has to be set on a contour for the
full length of its rockbed according to Minnesota 7080 Code. The contours in this case
are not continuous enough to site the full length of the rockbed. Thus there are two parts,
not two sites.
2. Furthermore, based on contours alone and the nature of the contours indicated above, it is
not feasible to simply begin to move, shift or slide the system anywhere from where it is
now sited. I spend time with the laser level establishing contours initially and they just
where not very conducive to set a full length Mound practically anywhere on the site.
The contours, and the slope, another important and code aspect of designing a septic,
both work best where the Mound is now designed. Out in the lawn area towards the
home, the contours are short, and become nonlinear, and the slope drops to nearly zero.
In other words, slightly undulating in different directions making it difficult to set a
Mound with the highest level of confidence in longevity. Zero slope meets the code, but
it is riskier to place as Mound on zero percent slope that is slightly undulating because the
effluent is more difficult to evaluate where it will go and pond and soak up. A definitive
slope defines clearly the direction of effluent flow. I always try to avoid siting a Mound
on slope less than 1-20/6.
3. Thirdly,
to have a
septic system verses a standard type I. Going out into the lawn towards the home has
soils that have some indication of disturbance, most likely from the home building
process. This disturbance can include mining of soils, addition fill soil spread over
natural soil, soil compaction, slow percolation, all of which become much less suitable
for the performance of a septic system of almost any sort. A few soil samples cannot tell
the whole story with soils that have been altered or impacted by construction activity.
The may not accept effluent over a long time, the effluent may not be treated as
SCANNPD
effectively as a soil with its natural properties of texture and structure, and the effluent
may hit compacted layers and move laterally and potentially discharge at some point
being untreated septic effluent. Disturbed soils are much higher risk of failing to take
effluent and failing to treat effluent. The best soils with sufficient slope and contours are
always the best choice in protecting the environment and protecting public health and
safety.

The Narrative for the 821 Creekwood Drive, Chaska, MN 55318
(Mailing Address)
Submitted by homeowners: Gene and Lowie Sipprell
August 20, 2018
On May 29, 2018, we purchased 821 Creekwood Drive as our primary residence. As
part of the process we requested that the lot be surveyed, septic and water systems
be tested. The results indicated the septic system was found to be inadequate to
current standards and would need to be replaced within two years. As we inquired
into this process we learned if we ever wanted to add another bedroom we would
need to have a double mound system. We consulted septic system installer Dale
Dern of Homestead Septic before the purchase of the home. He drew up two or
three different double -mound systems providing a way for water movement across
the property.
In June, 2018, we met with the city representatives at the proposed new site for the
septic system. They advised that the only location for a double mound system
would be in the far north eastern corner of our lot and a variance would be needed
to address the requirement setback to be 50 feet from the bluff.
July, 2018, Sathr-Berquist, Inc of Wayzata completed two surveys: surface lot and
bluff elevation. (See previously submitted documents)
August, 2018, we met with the neighbors including Michael Cohrs, General
Manager/Course Superintendent of Bluff Creek Golf course that adjoins our
property. They are supportive of installing the new septic system. Our realtor, Rick
Brama has advised us on a landscaper who could provide us with a beautiful design.
Consequently, we are confident that we can install the required septic system and a
beautiful landscaping area that will enhance our neighborhood.
We look forward to answering any questions the city may have and moving forward
so we can complete the septic system installation and landscaping this Fall.
Thank you for your assistance.
Sincerely,
Rev. Dr. Gene Sipprell

Septic System Variance:
Property: 821 Creekwood Drive
Chaska, MN 55318
A variance is needed that is within the 50 foot bluff setback ordinance.
In general, there are three situations whereby components of the new Mound Septic System will
be within 50 feet of the Bluff:
1. Septic and Pump Tanks
2. Pump line from pump tank to the Mound
3. The Mound
The reasons for the variances is as follows:
1. Septic and Pump tanks have to be where they are as that is where the old tanks are thus
the sewer line from the home comes out in that vicinity and the elevation of the sewer
pipe dictates where tanks need to go.
2. The pump line from the pump tank thus has to start at the pump tank location and
continue to the Mound. Physical features disallow any options to where the pump line
can be run.
3. The Mound has been located where it is due to the fact that the soils in this area are un-
disturbed, verses somewhat disturbed soils in the lawn area from initial construction. I
know that large trees indicate the most natural soils. Secondly, the contours are ever so
slightly undulating outside of where I set the Mound that is it difficult to set a Mound on
a definite contour to meet the Septic Ordinance. Lastly, if all of the Mound has to be
outside of the 50 foot bluff setback, there literally is not enough room to place any part of
the septic system.

Design Notes:
System is for a 6 bedroom Home. Soils only accommodate a Pressurized Mound Septic. Mound is
♦
split into two equal units on account of slope, short contours, drainage swale, and bluff line.
♦
Each Mound halve will have the sandbed and laterals at the same elevation based on sandbed
elevation of Unit 1. End feed from pump each unit, essentially center feeding Mound as single unit.
♦
Finish Mound as one unit and build saddle to divert all rain and snow melt.
♦
♦
Pump station is designed for a dual pump arrangement with an alternating dose panel. Each
Mound half will have its own pump and be controlled by the dosing panel. Use either a dual
pump line, one for each mound half, or a single pump line with Check Valves properly installed
♦
♦
off of each pump. Calculate flow for each pump based on one half of total flow plus drainback.
♦
See design and pump pages.
♦
♦Install
pump line deep as possible and reverse pitch pump line so that all portions of pump line
♦
drain back into pump tank
♦
♦
Pump and fill old septic tanks.
Tree and brush removal necessary with some large trees to be removed. Cut stumps close to
♦
ground as possible and leave stumps intact. Only track machine shall be used in tree removal
♦
process to protect soils from undue disturbance and compaction.
Tight access for septic tank truck. Tree trimming required on residence trees and neighbors trees.
!
Variances to bluff for septic and pump tank, and for unit 1 of Mound may be necessary from City.
Bluff line approximated and not set officially by elevation or surveyor. Surveying and plotting of
all septic tanks, pump tanks, sewer lines, and both rock and sandbed absorption units suggested to
ascertain all setbacks to property lines and bluff.
