Site Plan Alignment Adjustments

IMEG provided civil engineering design services, along with landscape architecture and construction administration, for site plan alignment changes including updated architectural design for additional patios. The firm updated the alignment plan to include the new architectural footprints of the proposed buildings including minor shifts in the majority of the building locations. The scope included re-alignment of site walkways, adjustment of the proposed spot elevations, proposed contouring, and proposed utilities and drainage structures to maintain minimum required offsets/separation distances, and revisions of the proposed foundation planting designs.

IMEG coordinated and updated all drawings in the set for the revised alignments (labeling and dimensioning). Revisions were made to the on-site stormwater management system and to the proposed on-site stormwater volume calculations. IMEG redesigned the on-site stormwater management system that utilizes the ultra-light weight fill material for the required storage volume. Additional tasks included preparation of custom design details associated with the proposed storm water management system and coordination with the Town of Hempstead (TOH) Building Department to facilitate an updated 305 Site Plan Review, limited to the Town Engineering Department’s review.

IMEG coordinated the effort to prepare the additional information required in response to the National Flood Insurance Plan (NFIP) letter including the submission of the updated site plan review into a single resubmission package. Additionally, IMEG provided a plan adjusting the vertical datum of the designed project to National Geodetic Vertical Datum (NGVD 29. IMEG coordinated the preparation of the required Letter of Map Revision (LOMR) application. In regards to the New York State Department of Environmental Conservation (NYSDEC) Tidal Wetland Permit — fill conditions and building development in the adjacent tidal wetland area — IMEG prepared necessary plans, cross sections, exhibits, and the necessary NYSDEC applications.

The firm processed applicable documents with the NYSDEC for review and permitting. Key project features included:

• Compact site
• Shallow depth to groundwater
• Relocation of major utility easement
• Self-contained apartments for mechanical and electrical services
• Apartments are individually metered for electric and natural gas

Floating Docks and Access Gangways

IMEG coordinated and advanced the design and details of the proposed floating docks and access gangways with a selected vendor, based on the alignment currently reflected in the 305 Site Plan Drawing set. Necessary plans, cross sections, and exhibits were prepared, as well as the necessary NYSDEC and U.S. Army Corps of Engineers (USACOE) applications for a joint submission to the agencies for review and permitting. IMEG also prepared the necessary TOH applications for submission to TOH Department of Conservation and Waterways for review and permitting.
