Assumptions
Response to NHDES comments for all applications will occur sometime after FY2017.
Services required to prepare for/attend public hearings will be performed after
FY2017.
Services required for preparing/submitting the GMP and Title V renewal will not be
required until after FY2017.
The City will make available for use all historic engineering and hydrogeologic studies,
permit applications, reports, drawings, and calculations related to the Four Hills
Landfill site; additional subsurface explorations are not included.
The City will provide recent topographic survey (i.e., 2016) of the proposed Phase IV
area in a digital format that is compatible with AutoCAD Civil 3D. The survey will be
geo-referenced to the existing site benchmarks, and references the state plane
coordinate and vertical datum used. The resulting topographic map will be produced at
a scale of 1 inch equals 40 feet, with 2-foot contours.
The budget and schedule do not factor an allowance for delays caused by possible
opposition or litigation.
Potential changes to the NHDES rules are not accounted for.
Field sampling or testing (groundwater, stormwater, surface water, soil, or waste) are
not accounted for; Sanborn Head will rely on historic information to be provided by the
City.
Closing
We appreciate the opportunity to be of continued service to the City. Please contact me
should you require additional information.
Very truly yours,
SANBORN, HEAD & ASSOCIATES, INC.
