Melanie Curtis
Pianning and Zoning Coordinator
City of Orono
Crystal Bay,Mn 55323
Regarding: My response to Bob Bean's 5/1/15 comments about the subterranean interlocking grid system
(Sub Grid)proposed for the Douglas Smith Project
Ms.Curtis,
Per my resent phone conversation with Bob Bean,I am adding the following clarification details to the layout
drawing for this project.
1) Virgin or natural clay soils must be used for maximum compaction and to provide proper drainage. This clay
soil must contain less than 10 percent fine granular material. Properly compacted soil of this type is to
reduce water retention. We can expect holding forces in the range of 500 pounds per square foot against
the vertical members of the grid if compacted per this requirement.
2) The use of treated 5 inch by 6 inch timbers are recommended for this project. Alkaline Copper Quaternary
(ACQ)treated timbers are required.
3) The use of Hex-head steel heavy duty wood screws rated for treated(ACQ)timbers are required. Ten inch
long#12 coarse thread or larger should be used.
4) Vertical posts must be set in place in 4 foot or deeper virgin or natural clay.
5) Clear medium aggregate collection zone is required on every layer of the grid. 4 inch drain tiles are required
at the bottom of each layer to illuminate hydraulic water pressure against the walls. Each tile must be
connected to vertical tiles that lead to the shoreline rip rap.
6) Double rows of silt fence must be used by the installation contractor prior to construction wherever possible.
7) Because of our concerns regarding erosion and sediment control within the project area my
recommendation is that only experienced contractors with proven successful installations should be
considered for hill side restorations of this type.

Subject: Doug Smith application
Dale
On Tuesday,Jim Smith came in and filled out the zoning permit application form for the work on Doug Smith's
property. As we discussed, two full sets of all plans and surveys and supplemental information must accompany this
permit application. We do not have the staffing time or means to copy plans from the CUP file to the zoning files for all
applicants.
The permit will be on hold until the remaining information is dropped off.
Thanks.

Regarding. My response to gob Bean's 5/1/15 commer� about the subterranean interiodcing grid system
(Sub Grid)proposed for the Dougias Smith Project
Ms.Curtis,
Per my resent phone conversafion with Bob Bean,l am adding the fiollowing clarification details to the layout
drawing for ifiis project.
1) Virgin or natural clay soils must be used for maximum compaction and to provide proper drainage. This clay
soil must contain less than 10 per�cent fine granular material. Properly compacted soil of this type is to
reduce water retention. We can expect holding forces in the range of 500 pounds per square foot against
the vertical members of the grid if compacted per this requiremen�.
2) The use of treated 5 inch by 6 inch timbers are recommended for this project. Alkaline Copper Quaternary
(ACCU treated timbers are required.
3) The use of Hex head steel heavy duty wood screws rated for treated�ACQ)timbers are required. Ten inch
long#12 coarse thread or larger should be used.
4) Vertical posts must be set in place in 4 foot or deeper virgin or natural ctay.
5) Clear medium aggregate collection zone is required on every iayer of the grid. 4 inch drain tiles are required
at the bottom of each layer to illuminate hydraulic water pressure against the walls. Each file must be
connected to vertical files that lead to the shoreline rip rap.
6) Double rows of silt fence must be used by the installafion contractor prior to construction wherever possible.
7) Because of our ooncerns regarding erosion and sedimerrt control witfiin tfie project area my
recommendatian is that only experienced contractors with proven successful installations should be
considered for hill side restorafions of this type.

Engineering Review#1
Dear Melanie:
As requested, we have completed an engineering review of the documents submitted for the above
referenced project. We offer the following observations,comments, and recommendations for your
consideration:
1. The Applicant is proposing to perform site grading of approximately 415 cubic yards and install
riprap along the shoreline. If material is to be imported to the site,the City should consider the
following:
a. The City Engineer should be allowed to inspect any riprap or fill being imported to the site prior
to it being placed.
b. The Applicant should confirm with the City Engineer acceptable hours of truck hauling and
provide documentation on the haul route to be used. Acceptable hours and haul route should be
approved prior to the importing of any riprap or fill.
c. The City Engineer should inspect roadways on haul route prior to and following completion of
work to determine whether adverse impacts have occurred.The applicant should be responsible
for the repair to roadways for any adverse impacts.
2. It is uncleaz what information is portrayed on the Green-Dale Design Plan. A legend should be
included that defines existing and proposed features indicated on the plan.
3. It appears that work is proposed below the 100 year flood elevation. Any fill below this elevation
must be mitigated for prior to any fill being placed in the floodplain. Plans should be revised to
indicate location and amount of floodplain fill proposed and location and amount of floodplain
mitigation provided.
4. The information submitted indicates riprap is to be installed to stabilize the shoreline. However,the
plans are unclear where riprap is to be placed. The plans should be revised to clearly indicate
location of riprap. The size of rock to be used for shoreline stabilization should be specified on the
plan. Minimum Class V riprap(6"to 30")is recommended.
5. The plans are unclear what is proposed for retaining walls. The Green-Dale Design Plan should be
revised to provide more detail for all proposed retaining wall work. Top of wall and bottom of wall
elevations should be provided in key locations (i.e. grade changes and alignment changes). Spot
elevations provided should clearly indicate location of proposed elevation. Walls four feet or greater
in height must be designed by a Professional Engineer, and plans and calculations specific to the
proposed walls must be submitted for review and approval. Multi-level walls spaced less than
double the height of the bottom wall apart shall be considered one wall, and the height shall be
determined from the base of the bottom wall to the top of the upper wall.
6. The plans should be revised to include cross-section details of the proposed work to indicate how
walls will be integrated with�riprap at the toe of slope, location of draintile and tie-backs,fill material
Conditional Use Permit 15-3725
. r 4167 Highwood Road

to be used,and location and elevation of timbers.
7. Since work is proposed within 50' of Lake Minnetonka,redundant erosion control devices must be
installed down gradient from the work to ensure adequate protection. Double rows of silt fence
should be installed by the Contractor and inspect�d by the City prior to any land disturbing activities.
Silt curtain should also be installed where shoreline remediation and riprap placement is proposed.
8. Disturbed areas must be permanently stabilized within 7 days of completing grading and wall
construction operations. The Green-Dale Design Plan should be revised to indicate locations and
schedule for re-vegetation or a Landscape Plan should be submitted with the necessary information.
9. Due to the extent of work proposed,it is recommended that a financial security of$5,000 for erosion
control and engineering oversight be required of the Applicant. The financial security is intended to
provide protection in the event that it becomes necessary for the City to install or maintain erosion
and sediment control within the project azea and covers the cost of vegetation re-establishment if the
applicant is unable to follow through with the conditions of approval.
10. The Minnehaha Creek Watershed District(MCWD)permit submitted appears to be out of date and
does not adequately cover the work proposed.The applicant should resubmit plans to MCWD and
may be required to obtain new MCWD approval and permitdng for their Erosion Control,Shoreline
and Streambank Stabilization,and Floodplain Alteration Rules. A copy of any approved permits
should be submitted prior to any land altering activities.
Please let me know if you have any questions or need additional information.
Sincerely,
BOLTON&MENK,INC.

schedule for re-vegetation or a Landscape Plan should be submitted with the necessary information.
4. The size of rock to be used for stabilizing the base of the sub-wall system should be specified on the
plan. Minimum Class V riprap (6"to 30")is recommended.
5. Due to the extent of work proposed, it is recommended that a financial security of$5,000 for erosion

6. The applicant may be required to obtain Minnehaha Creek Watershed District(MCWD) approval
and permitting for their Erosion Control, Shoreline and Streambank Stabilization, and Floodplain
Alteration Rules. A copy of any approvals or permits required should be submitted prior to final
approval.
