Petry Letter Dated 7 8 2022 Outlining Changes

PETRY e ENGINEERING, LLC July 8, 2022 West Orange Zoning Board 66 Main Street West Orange, New Jersey 07052 Attn: RE: Diana Chandler Board Secretary ZB-21-22/19 Wheatland Development LLC Block: 39; Lot: 56.06; Zone: R-6 17 Wheatland Avenue Dear Ms. Chandler: Pursuant to the Zoning Board meeting on the evening of May 19", we have revised our plans based on the feedback from the Board. We have enclosed six signed and sealed hard copies along with a flash drive containing PDF versions. Below is a breakdown of the updates, clarifications related to Board questions, and additional information we have obtained for the property. The Board had questions regarding the basement/cellar of the proposed home. Our SSP- 1 sheet has been revised to include the “cellar determination” calculation as set forth in your ordinance. The lowest level of the home is a cellar. The applicant will commit that they will not finish the cellar as part of their work. However, your ordinance allows for the future homeowner to finish this space, as there is no restriction against this action. Soils testing was performed on June 21* to determine the presence/absence of bedrock within the area of the basement, the presence/absence of groundwater within the area of the infiltration basin, and the permeability of the soils. o Based on this testing no bedrock or groundwater was encountered in any of the test pits. Additionally, the soils have a permeability rating of 1.65 inches per hour which is greater than the 1 inch per hour assumed in our original design efforts. As such, a full cellar and all the proposed walls can be constructed without the need for rock removal. The Grading Plan has been modified to reduce the retaining wall height to a maximum of 5°-6”, which eliminates the need for a variance for the height of the wall. The material of the retaining wall has been changed to a modular block wall. This is a more attractive option than poured concrete and also results in less disturbance to the area during construction. The manufacturer of the modular blocks is Redi-Rock. Details are included on SP-3 of our submittal. 155 Passaic Avenue, Suite 350, Fairfield, New Jersey 07004 973-227-7004 963-227-7074 (fax) www.petryengineering.com
