These recommendations are based on my original design dated August 24, 2022, and my site observations and discussion with you on October 31 and November 17, 2022. This previously designed work is recommended to be completed at this time to improve the site grading by reducing the steepness of some slopes and will reduce the chances of erosion at the top of the newly built, tiered timber retaining wall system. I recommend that the final, planned timber retaining wall be constructed 4 to 6 feet behind the uppermost existing wall. The wall should extend from several feet inside both the east and west property lines. Most of the wall will have a maximum exposed height of about 2-feet. The wall height will increase to about 4- feet tall near each end where existing slopes increase. Following completion of the final wall, erosion control should be established and maintained in all disturbed areas. Areas of concentrated runoff should be directed away from the top of the walls. As before, 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: 4 to 6 feet behind the top of the existing upper wall  Wall height(s): 4-feet to 2-feet as noted (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 wall: None  5:1 maximum slope at top and bottom of wall  Wall Type: 6”x5” Treated Timber  Connections: 3/8” galvanized or treated spikes  Drainage pipe: Required As we discussed, you are planning to that the as-built conditions surveyed for city consideration. Please forward this to me when it is completed. 2815 Casco Point Road, Wayzata, Minnesota November 18, 2022 Page | 2    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: 2815 Casco Point Road, Wayzata, Minnesota November 18, 2022 Page | 3    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.

COPIES OF DOCUMENTS: ENGINEER agrees to furnish CLIENT with an electronic copy of our report, drawings, or documents relating to the services performed. Hard copies, bound or unbound, may be provided upon request at charge of cost plus 10 percent, at ENGINEERS’s sole discretion. ENGINEER shall retain an electronic copy of the final documents in its files for a period of five years. 6. INSURANCE: ENGINEER represents and warrants that it is protected by Workers Compensation insurance and has such coverage under Public Liability and Property Damage insurance policies which ENGINEER deems adequate. Certificate for all such policies of insurance shall be provided to the CLIENT upon request in writing. ENGINEER shall not be responsible for any loss, damage or liability arising from any acts by CLIENT, its agents, staff and other consultants employed by it. 7. TERMINATION: This agreement may be terminated by either party by written notice. In the event of termination, ENGINEER shall be paid for services performed and expenses incurred up to the termination notice date. Neither CLIENT not ENGINEER may delegate, assign, sublet or transfer his/her duties or interest in this Agreement without the written consent of the other party. 8. LIMITATION OF LIABILITY: To the fullest extent permitted by law, CLIENT and ENGINEER (a) waive against each other, and the other's employees, officers, directors, agents, insurers, partners, and consultants, any and all claims for or entitlement to special, incidental, indirect, or consequential damages arising out of, resulting from, or in any way related to this report, (b) agree that ENGINEER’s total liability to CLIENT shall be limited to the total amount of compensation received by ENGINEER, (c) agree that CLIENT will defend, indemnify, and hold harmless ENGINEER from and against any claims, liabilities, actions, demands, losses, damages, costs and expenses sustained by any third-party not granted reliance on ENGINEER’s reports and services, (d) agree that any action arising out of or related to the services provided must be brought to ENGINEER’S attention no later than two (2) years after the date of the services, and (e) if an action is brought against the ENGINEER and the ENGINEER prevails, ENGINEER shall be entitled to recover costs and expenses, including reasonable attorneys' fees and costs. 9. FORCE MAJEURE: The engineer shall not be responsible or liable for any failure or delay in the performance of its obligations under this contract arising out of or resulting from any cause or event beyond our control, such as war, strike, crime, epidemic/pandemic, regulations and/or restriction imposed by any government agency, or other event. 2815 Casco Point Road, Wayzata, Minnesota November 18, 2022 Page | 4    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.
