2 could not support infiltrating the amount of water needed for a community septic system. This is described in greater detail below. Issue with OP-PUD: Community Septic System - After conducting numerous soils tests, we believed that we had found an area of the site that would be acceptable for a community septic system. Our consultants were very confident and that is why we moved forward with the preliminary plat and with a fully designed community septic system. Our consultants held severa l pre-application meetings with the state regarding our application. We thought we were well on our way. During one of the final meetings with the state it became clear that the state would be requesting a study we had not completed called a mounding study. This is a relatively new requirement for community septic systems. We completed an initial mounding study. That study indicated there could be some issues with the hydraulic conductivity assumptions we were using that came from tests done by the St. Anthony Falls Laboratory of the University of Minnesota. So, to be safe, we hired Braun InterTech to conduct additional soil tests to make a more precise hydraulic conductivity assessment of the soils at Highpointe Crossing. These tests were completed in late December. The results of the test were entered into the water mounding model in early January. After entering these test results into the model, it became clear, based on the mounding study, that the community system would eventually fail and could fail as soon as in the first year of operation. A surprise to us and our consultants. Now What? This left us with a couple possible alternatives. 1. See if a rural lot individual septic system development was feasible. 2. Develop Highpointe Crossing as approved except with a connection to a municipal sanitary sewer in the City of Lake Elmo or in the City of Oakdale. Alternative 1 - Large lot rural development with individual septic systems vs. community system We spent a couple months evaluating plans for individual rural septic lots. We initially tried this using the Residential Estate (RE) zoning district. In the end that zoning district did not provide us with enough homesites to pay for the development of the neighborhood. Also, some of the standards in the district, like the 100’ front yard set-back, created constraints that would have made it difficult to locate individual septic systems on the homesites. So, we then designed a neighborhood using the Rural Single Family (RS) zoning district as our guide. We realize that this is an older district that is being phased out and that it has only been used in limited situations. That said, it is refenced in the Comprehensive Plan as one of the two districts that were combined to create the Rural Single Family (RSF) designation which is what the Eberhard property is
