—_— Me Ove ASSOCIATES Chairman and Members of the West Orange Township Zoning Board December 13, 2023 Re: Jose De Oliveira (ZB-23-11) CORRECTED March 13, 2024 Bulk Variance - Review #1 Our File No. VWRZ0061.01 10. 11. 12. 13. Page 3 It shows on the Northeast Wall Elevation that the upper retaining wall will have a height of 6’-8” and the lower retaining wall will have a height of 5’-8”. Construction Note #1 on sheet C-01 lists the soil parameters that were used in the design of the retaining walls. In addition, Retaining Wall General Note #2 states that KSI Engineering PC has not verified these design conditions, and if required the soil parameters should be confirmed by the site geotechnical engineer or others prior to wall construction. Therefore, the Applicant should address the Board regarding their plans to have a geotechnical confirm the site parameters prior to construction. Construction Note #5 states that hydrostatic loading is not considered in tie analysis. Sufficient drainage must be provided such that the hydrostatic loading (poor pressure) does not develop in the reinforced zone. The plans should be revised to show the required drainage system. In addition, the Applicant must demonstrate to the Board that the drainage discharge will not negatively impact the adjoining properties. Construction Note #10 states that a qualified engineer or technician shall supervise the wall construction to verify field and site soil conditions. The Applicant should address the Board regarding their plans to comply with this recommendation. Construction Note #12 states that the site grading shall be designed to route surface water around and away from the wall. Therefore, the plans must be revised to show the proposed grading at the site. Sheet C-02 includes a Geogrid Design Chart which sets for the geogrid requirements for various wall heights. We note that the maximum wall height shown on the chart is 11.0 ft whereas the plans show that the northeast retaining wall will have a maximum height of approximately 12’-6”. This discrepancy must be resolved. Due to the proposed retaining wall heights, the Applicant should address the Board regarding their plans to install a safety fence along the top of the retaining walls. The Applicant is hereby advised that any revised plans or other documents submitted to the Board should be accompanied by a
