J&K’s letter (8.3.20) states: “CGS…recommended “basements should not be allowed in areas where observed groundwater levels are shallower than 14 ft. below planned final grades…” J&K also reviews RMG’s work (dated 6.19.20) which is being used in part to determine the suitability of basement construction on lots 87-90 and state: “As the groundwater measurements from the RMG report…show on lots 88 and 89 this requirement has been surpassed.” Additionally, they state in their Ground Water Table Study for Filings 9 & 11 dated 2/16/2019: “As the groundwater measurements show this requirement has been surpassed in all areas of the development that were of concern for shallow groundwater.”
A purpose of groundwater monitoring is to determine depth to groundwater but another purpose is to determine seasonal groundwater fluctuations that should be expected. No discussion of seasonal groundwater fluctuations and their impact to water level in lots 87-90 has been provided. Piezometer P-6 from the 2019 study is the closest (~500+ feet to the south) to lots 87-90 and the only one in Filing 9. On February 26, 2018 groundwater in P-6 was reported at a depth of 21’ 8”. The shallowest groundwater measurement (18’ 4”) was on August 14, 2018, or a 3’ 4” seasonal fluctuation. On February 5, 2020 RMG measured groundwater (lot 89) at 16’. Apply seasonal fluctuation measured in P-6 of 3’ 4” and the groundwater can be expected to be less than the 14’ recommended.
We were not provided with elevation data for RMG’s test borings or for final grades of the lots. The data submitted is inconclusive in determining if the groundwater requirement (14’ below finished grade) has been met in lots 87-90. However, if the lots were drilled at finished grade than the data provided suggests basements should not be allowed.
CGS recommends that prior to basement approval for lots 87-90 that the applicant provide:
• Elevation data of final grades for lots 87-90 and elevation data of RMG’s test borings (88 and 89).
• Discussion of seasonal groundwater fluctuations and their expected impact to water levels in lots 87-90.
