Highpointe Crossing - 2298 Inwood Ave N – Lake Elmo – Preliminary Plat Narrative June 7, 2024 Page 10 10 closed because of some type of emergency. The study also shows that the traffic generated by our neighborhood can be handled by the existing roadway systems, including Inwood. To handle the traffic safely our neighborhood will also include building a full right and left turn lane access into the neighborhood unlike either of the neighborhoods to the north and south which both access Inwood and only provide a right turn lane and bypass. We did not comment on the speed on Inwood since we do not have control over the speed of the current traffic on Inwood. • Minimize construction traffic through adjacent neighborhood – Residents in the neighborhood to the north would prefer that all construction traffic use the Inwood access o Response – We are okay requiring that of our builders once home construction starts. There could be times in the early stages of site construction when the Imperial access would be used on a very limited basis, most likely for delivering equipment. • Noise from Septic System – Some neighbors living adjacent to the community septic system drain field were concerned about noise coming from the operation of the system. They used the example that the City had told them the well booster station was supposed to be quiet but they say it’s not. They are now concerned that when we say there will be no noise that there will actually be noise. o Response – The current noise issue appears to be when the power goes out and backup generators are needed for the booster station. Adjacent residents said this is an issue because the power goes out frequently in their neighborhood. When the Community System is up and running there will be little to no discernable noise from the day to day operation. There will, like the booster station, be a backup generator. Based on the neighbors’ concerns we will locate our backup generator on the south side of the small control shed. When it runs, only during power outages, the generator will be buffered by the shed and it will likely be unnoticed by the neighbors. • Concerns about the appearance of the drain fields – There were some concerns that residents adjacent to the drain fields were not getting the same true 200’ buffer that other residents were getting. o Response - In general, the drain field will look like all the other opens spaces. There will be slight undulations within the prairie. A majority of the mounds in the drain field will not rise more than 1’ over the existing elevation. A small portion of the westernmost mounds will rise 2.5’. We tested soils across the entire property and the area along the northern boundary was determined to be the best location for the community treatment system. To help the residents who are adjacent to the primary drain fields we increased the buffer in this area from 200 feet to 250’ feet. • Possible Septic System Odor – There were some concerns and questions about odors coming from the treatment system.
