An additional test pit was conducted for the foundation to determine estimated seasonal high groundwater and it was found to be consistent with previous data and the basement would be above the estimated seasonal high groundwater elevation.Mr.Bitsko inquired about the changes to the dwelling footprint compared to the approved Order referenced plan.Mr.Griecci stated that there was ambiguity regarding the 1960 variance on location of carport allowance and it was decided that the carport location would be as shown on the current revised plan. On a motion by Mr.Bitsko and seconded by Ms.Dohan,the Commission voted 4-0 in favor to approve the plan changes as insignificant without requiring an Amendment to the Order of Conditions.
