RTG was responsible for completing the engineering and design for the Town’s selected alternative, which consisted of a driven sheet pile wall with a landside earthen berm and waterside riprap scour protection. The design included performing analyses of the proposed barrier, designing the barrier to account for existing utilities, incorporating a new stormwater run-off treatment system, and preparing budget-level construction cost estimates.
In addition to the above, RTG was responsible for applying for the required local, state, and federal regulatory permits for the project. As a part of this, RTG also prepared a FEMA Conditional Letter of Map Revision (CLOMR) Application in order to reclassify the FEMA flood zone in which the WWTF was located from a VE Zone to an X Zone.
Construction of the Project was recently completed, during which RTG provided Construction Phase Services including administrative and observation tasks.
