_ ASSOCIATES Chairman and Members of the West Orange Township Zoning Board November 1, 2022 Re: 89 Ashland Avenue, LLC (ZB-22-09) Our File No. VWRZ0061.01 Preliminary & Final Site Plan with Page 4 Cc. ‘C’ & ‘D’ Variances - Review #1 16. Sheet 3 must be revised to show the dimensions of the proposed refuse/recycling enclosure. In addition, a detail of the refuse/recycling enclosure must be added to the plans. 17. The Applicant should provide testimony to the Board to demonstrate that the proposed refuse/recycling enclosure will have adequate capacity to accommodate the trash and recyclables that will be generated at the site. 18. It shows on sheet 4 that the proposed increase in impervious cover at the site is 1,646.2 sf. As a result, the Applicant proposes to install an underground infiltration system to recharge the increase in stormwater runoff from the site. The underground infiltration system will consist of 100 If of 18” perforated HDPE pipe installed in a stone bed with an ‘E’ inlet on each end. 19. Sheet 4 includes a calculation of the required stormwater storage/recharge volume. The calculation is based on a proposal to infiltrate 3.0” of runoff over the increased impervious cover area. The Applicant should address the Board regarding how the infiltration of 3.0” of runoff over the increase in impervious cover was selected as it is less than the normal design storm runoff. 20. In order to verify that the underground infiltration system will function as designed, the following additional information is required: a) Asoil boring must be performed at the location of the underground infiltration system to a depth of at least 5 ft below the bottom of the stone bed beneath the pipe. . b) A permeability test must be preformed at the location of the underground infiltration system to demonstrate that the system will function as designed. c) Time to drain calculations must be provided to demonstrate that the underground infiltration system will drain within 72 hours following a storm event. 21. We note that the property in question currently consists of two (2) lots. As a condition of any approval granted by the Board, it is our recommendation that the Applicant be required to consolidate the two (2) existing lots. Prior to recording, a copy of the proposed Deed of Consolidation must be submitted to the Board for review and approval by the
