The additional items required to be added to the project beyond the original City approval in 2008 has caused the project to exceed its authorized impervious area contribution to the Meadowland Business Park Operational Stormwater Permit. As such, we will need to undertake supplemental work to mitigate this and will need additional time to determine what this will do to the project design. We ask that a continuance of approximately three months be provided so that we can facilitate the supplemental stormwater design and authorization of the additional impervious areas with the State. Although you have already boiled down the outstanding issues in your previous email correspondence, we have taken this opportunity to provide a formal response to the March 4, 2020 Staff Report action items.
