RE: Segmental Retaining Wall Typical Section
Project Location: 2815 Casco Point Road, Wayzata, Minnesota
Project No. 22-6589
Dear Mr. Peterson:
This letter includes important details regarding the attached design typical engineered sections for the
timber retaining walls at the above location. This design is based on wall layout information provided by
you in an email on August 23, 2022, including: a Certificate of Survey prepared by Gronberg and
Associates dated May 18, 2022; measurements of the wall heights and face to face distances; and
photos of the existing conditions.
The attached typical section should be referenced for construction details. Special note should be made
of the wall embedment depth and the tieback/header and deadmen lengths. Refer to local building
codes, industry specifications, and American Wood Preservers Association for installation information and
details.
The design of the wall system assumes the following:
Wall location: Replacement of the existing tiered timber walls in the same configuration
Wall height(s): 7-feet to 2-feet as noted on the attached sketch, with minimum face-to-face
distance between the walls (maximum exposed heights)
Minimum embedment depth = 6” min., or as noted
Soil conditions: Silty/Clayey Sand, friction angle = 30.0 degrees, unit weight of 125.0 lb/ft3
Required minimum soil bearing capacity = 1500 psf
Surcharge load at top of walls: Decks as noted
10:1 maximum slope at top and bottom of walls
Wall Type: 6” Treated Timber
Connections: 3/8” galvanized or treated spikes
Drainage pipe: Required
These walls have not been designed for ground water surcharge loads. Direct all surface and
groundwater drainage away from the walls. Methods to do so include but are not limited to the following:
drainage swale, site grading, retention ponds, etc. Details of water control are left to the wall contractor or
the site civil engineer. Please contact Criterium-Schimnowski to provide additional site assessment
services if desired.
The wall design was performed using the design guidelines presented in timber retaining wall industry
guidelines and recommendations. Additional information requested by Criterium-Schimnowski Engineers
but not available includes: geotechnical site survey and soil data. If soil conditions, proposed wall layouts,
or other design parameters vary from that assumed, a revised analysis may be needed. Please call me if
you have any questions or need more information.

Retaining Wall Completion Reports and
Construction Inspections
To: Retaining wall contractors and/or all clients utilizing our services for retaining wall engineering.
From: Paul Schimnowski, PE
Retaining Wall Engineer
Criterium‐Schimnowski Engineers (CSE)
Paul@CriteriumMN.com
Date: April 1, 2022
To help contractors and other interested parties navigate the changes that many cities and jurisdictions
are making regarding construction inspection requirements and final approval letters, we are making
the following recommendations:
1. Request that the City Building Official complete the Required Inspections of Retaining Walls
form, attached.
2. Notify your client of the potential for added cost depending on city/building official
requirements. Contact our office or refer to our service agreement for current fees.
3. Contact Criterium‐Schimnowski Engineers to schedule any required inspections. Adequate lead
time is required. Similar to typical City inspections, at least one week is recommended. We
cannot guarantee immediate service.
4. Take daily construction progress photos for your records and for submittal to Criterium‐
Schimnowski Engineers upon request.
5. Complete the Statement of Conformance for your records and for submittal to Criterium‐
Schimnowski Engineers upon request. Form attached.
If a Wall Completion Report (Post‐built Conformance Letter), is requested of CSE, we will require that
you provide construction photos and Statement of Conformance. In addition, CSE will need to perform
a site visit once final grading is completed. Without these three items, we are unable to comment on
the construction/conformance of the wall.
We are here to help as much as possible. These inspection requirements are not coming from us.
Contact us if you have any questions.

DESIGN PROVISIONS:
1. REFER TO WOOD RETAINING WALL INDUSTRY GUIDELINES.
2. SEE PRODUCT MANUFACTURER INSTALLATION RECOMMENDATIONS FOR CONSTRUCTION SEQUENCE
AND INSTALLATION NOTES.
3. THE DESIGN OF THIS RETAINING WALL SYSTEM WAS BASED UPON THE EFFECTIVE STRENGTH
PARAMETERS SHOWN ON THE “SOIL VALUES” TABLE. UNLESS OTHEWISE NOTED, NO FORMAL SOIL
INFORMATION WAS PROVIDED BY THE OWNER OR OWNER’S REPRESENTATIVE. IF SOIL CONDITIONS
VARY AT TIME OF CONSTRUCTION, WALL ENGINEER MUST BE CONTACTED TO DETERMINE IF A REVISED
DESIGN IS NEEDED.
4. THE WALL DESIGN WAS BASED ON THE INFORMATION NOTED IN THE LETTER ABOVE.
5. REFER TO WALL CALCULATIONS FOR BEARING CAPACITY REQUIREMENTS.
6. NO PRODUCT/MATERIAL SUBSTITUTIONS WILL BE ALLOWED WITHOUT PRIOR WRITTEN PERMISSION OF
CRITERIUM‐SCHIMNOWSKI ENGINEERS.
7. FINAL SITE GRADES AND ROOF DRAINS SHALL DIRECT RUNOFF AWAY FROM ANY RETAINING WALL(S).
UNLESS OTHERWISE NOTED, THE WALL(S) HAS NOT BEEN DESIGNED FOR HYDROSTATIC SURCHARGE
LOADING.
8. THE WALL DESIGN WAS PERFORMED USING DESIGN GUIDELINES PRESENTED IN THE THIRD EDITION OF
THE "DESIGN MANUAL FOR SEGMENTAL RETAINING WALLS" PUBLISHED BY NCMA.
