PROPOSED BOULDER RETAINING WALLS 4745 NORTH SHORE DRIVE ORONO, MINNESOTA GENERAL NOTES I. IN PREPARATION OF WALL DESIGN, SOIL STRENGTH PARAMETERS WERE DETERMINED IN THE FIELD BY A VEC REVIEW OF THE ON -SITE SOILS. IT IS THE RESPONSIBILITY OF THE OWNER OR OWNER'S REPRESENTATIVE TO VERIFY THE SOIL STRENGTH PARAMETERS ARE REPRESENTATIVE OF THE SOILS AVAILABLE FOR WALL CONSTRUCTION. IF THE SOIL STRENGTH PARAMETERS ARE FOUND TO BE INCONSISTENT WITH THOSE ASSUMED, THIS DESIGN IS NO LONGER VALID AND IT IS THE RESPONSIBILITY OF THE OWNER OR OWNER'S REPRESENTATIVE TO NOTIFY VEC SO THE RETAINING WALL SYSTEM CAN BE REDESIGNED. FAILURE TO NOTIFY VEC MAY RESULT IN FAILURE OF THE RETAINING WALL. 2. DESIGN SOIL PARAMETERS: A. RETAINED SOIL: IMPORTED/ON-SITE CLAYEY SAND SOILS PHI = 30 DEGREES GAMMA = 125 PCF. B. FOUNDATION SOIL: IMPORTED/ON-SITE CLAYEY SAND SOILS PHI = 30 DEGREES GAMMA = 125 PCF. 3. ANY EXCAVATION PERFORMED BELOW THE FOUNDATION GRADE OF THE WALL SHOULD HAVE PROPER 1:1 LATERAL OVERSIZING. EXCAVATION OVERSIZING SHOULD BE MEASURED FROM THE FRONT TO THE BACK OF THE LOWEST BOULDER. 4. THIS SET OF BOULDER RETAINING WALL PLANS ARE BASED ON THE SITE SURVEY, PREPARED BY ACRE LAND SURVEYING, DATED 11/12/2024. IF OTHER PLANS ARE PRODUCED THAT CONTAIN DIFFERENT INFORMATION THAN THAT REFERENCED, THIS PLAN MAY NEED TO BE REVISED AND/OR THE WALL MAY NEED TO BE REDESIGNED. 5. LOCATION OF THE BOULDER RETAINING WALLS IN RELATION TO PROPERTY LINES, UTILITY EASEMENTS, WATERSHED EASEMENTS, OR ANY OTHER TYPE OF EASEMENTS ARE THE RESPONSIBILITY OF THE OWNER. VEC ASSUMES NO LIABILITY FOR THE LOCATION OF THE BOULDER RETAINING WALLS, OR IF CONSTRUCTION OF THE PROPOSED BOULDER RETAINING WALLS ENCROACH ANY PROPERTY LINES OR EASEMENTS. 6. IT IS IMPERATIVE THAT THE SITE SURVEYING OF THE BOULDER RETAINING WALLS BE BASED ON THE PLANS REFERENCED ABOVE AND NOT PROFILE PLANS PREPARED BY VEC. SURVEYING OF THE BOULDER RETAINING WALLS MUST TAKE INTO ACCOUNT THE DESIGN BATTER INDICATED ON THE ENCLOSED PLANS AND DETAILS. FAILURE TO TAKE INTO ACCOUNT WALL BATTER FOR THE BOULDER RETAINING WALL SURVEYING WILL PRODUCE INCORRECT LOCATIONS OF ALL TOP OF WALL AND SHALL BE CORRECTED AT NO COST TO VEC. 7. WALL GEOMETRY, LOCATIONS, SLOPES AND SURCHARGE LOADS FOR THE BOULDER RETAINING WALLS WERE ASSUMED FROM THE PROJECT PLANS REFERENCED ABOVE. IF CONDITIONS VARY GREATLY IN THE FIELD FROM THOSE SHOWN ON THIS PLAN, VEC MUST BE NOTIFIED PRIOR TO CONSTRUCTION OF THE BOULDER RETAINING WALLS TO REVIEW THE DESIGN AND/OR PLANS. MODIFICATIONS TO THE DESIGN AND/OR PLANS MAY BE REQUIRED AFTER THE REVIEW, AND MAY TAKE UP TO TEN BUSINESS DAYS TO COMPLETE. 8. PLEASE REFER TO ANY PROJECT SPECIFICATIONS FOR ADDITIONAL INFORMATION. IF THERE ARE DISCREPANCIES BETWEEN ANY INFORMATION ON THESE PLANS AND INFORMATION IN THE PROJECT SPECIFICATIONS, THE MORE RESTRICTIVE INFORMATION TAKES PRECEDENCE. vicLer� Engineering & Consulting, LLC Post office P5ox 86 Grandy, MN 55029 Phone: 952-465-8272 www.vickeryeng.com ZOZ5 Vickery Engineering & Consulting, LLC, PROPOSED BOULDER RETAINING WALLS 4745 NORTH SHORE DRIVE ORONO, MINNESOTA TITLE PAGE AND GENERAL NOTES REV:I DATE: I DESCRIPTION: SHEET INDEX SHEET NO.
