MEMORANDUM
TO: Planning Commission
FROM: Drew Ingvalson, Planner
DATE: March 15, 2015
SUBJ: Shoreline Setback Variance — 9641 Meadowlark Lane
Planning Case #2016-07
PROPOSED MOTION
"The Chanhassen Planning Commission, acting as the Board of Appeals and
Adjustments, approves a shoreland setback variance from a tributary for the
construction of a single-family home, accessory structures, and driveway, as
shown in Attachment #2 of the memorandum dated March 15, 2016, subject to
the conditions of approval and adopts the Findings of Fact and Decision"
Staff is revising its recommendation to the Planning Commission regarding Planning
Case #2016-07 based on evidence obtained after the completion of the staff report.
City staff inspected the potential septic system sites at 9641 Meadowlark Lane on
March 11, 2016, inspections were not possible prior to this date due to winter
conditions. Upon inspection, staff found that the sites proposed by the applicant are
the best septic system sites due to unsuitable soils south of their location. Based on
this information, staff has withdrawn its recommendation of approving a plan based
on Attachment #15 of the staff report, which would have relocated the septic fields to
the south.
This leaves four alternatives available for the Planning Commission to consider for
Planning Case # 2016-07.
l.) Approve the variance request based on plans that move the house and garage
south of the septic sites (see Attachment #1).
Moving the house south of the septic sites would reduce the driveway
length and minimize the shoreline setback variance request to the
greatest extent possible. However, with the submitted house plan
without alterations, the structure will not meet the 50 -foot wetland
setback or the structure will not meet the 20 -foot septic system
setback. This plan will require the applicant to alter their house plan to
meet building code. The house will also lose views of Lake Riley with
this plan. This would be staff s preferred plan if the structure was
altered to meet the required setbacks.

2.) Approve the variance request based on plans that move the house east
(see Attachment #2).
This plan proposes moving the proposed house 9 feet east so that the east house
wall lines up with the east garage wall. This plan will provide a 79 -foot shoreline
setback from the tributary (exceeding the required shoreline setback for sewered
properties) and will reduce the shoreline setback variance request. This is staff's
preferred plan with the existing house plan.
3.) Approve the variance as submitted by the applicant (see Attachment #3).
The plan submitted by the applicant does not reduce the variance request to the
greatest extent possible. This is not staff's preferred plan.
4.) Deny the variance request.
RECOMMENDATION
Staff recommends that the Planning Commission, acting as the Board of Appeals and
Adjustments, approve a shoreland setback variance from a tributary for the construction of a
single-family home, accessory structures, and driveway, as shown in Attachment #2 of the
memorandum dated March 15, 2016, subject to the following conditions:
Planning and Building Department
1. The applicant shall apply for and receive a building permit and/or zoning permit for all
structures.
2. The applicant shall erect temporary fencing around the proposed septic locations prior to
any operation of equipment on the site.
Water Resources Coordinator
3. The plan must clearly indicate the shoreland impact zone and encroachment therein.
4. The applicant is responsible for any other agency approvals that may be required.
5. No site disturbance may occur until the city has received confirmation from the Board of
Soil and Water Resources that the wetland bank account has been debited thereby
satisfying the approved wetland replacement plan.
6. All erosion prevention and sediment control practices must be properly installed prior to
any earth disturbing activities.
7. Type II sediment control best management practices are required for all areas up gradient
of the wetland, the stream and the lake. This shall be machine sliced silt fence with metal
tee posts or other as approved by the City Engineer.
8. All other pertinent aspects of City Code Section 19-145 must be included with the site
plan including, but not limited to the placement of six (6) inches of topsoil to all
disturbed areas.
9. The city or their representative shall inspect the erosion prevention and sediment control
best management practices prior to any earth disturbing activities.

no closer than 100 feet to the Ordinary High Water Level (OHWL).
11. Clearing of vegetation along the shore shall be limited to a strip of 30 feet, parallel to the
shoreline and extending inward within the shore impact zone. The applicant shall use

ordinance.
12. Per city ordinance, all trees 10 inches and larger within the construction limits shall be
shown on the building permit survey.
