LAKE ELMO CITY COUNCIL MINUTES JUNE 2, 1987 PAGE y�• M/S/P Moe/Armstrong - to approve the preliminary plat for Springborn's Green Acres Second Additon as presented; subject to the lot lines being moved 50 feet to the north in order to get one acre for septic system on one lot. (Motion carried 5-0). Mayor Christ was unsure about an urban street here. He also pointed out that because the City Attorney seemed to think that the 1978 PUD could not be denied that this was a good example of why PUD's should not be allowed. .ai C. Preliminary Plat Approval: Lake Elmo Heights Second Addition n..q Don Bishop is requesting approval of a preliminary plat for 13 lots in phase two of the Lake Elmo Heights Cluster Development subdivision. The City Engineer's letter of 4-24-87 raised the following concerns: (a) Lot size for two lots exceeds the 2.0 acre maximum, unless the NSP powerline easement area is not included. (b) 27th Street North is a cul-de-sac which exceeds the 800 foot + maximum allowed by code. The City Council could allow the cul-de-sac if it is considered to be temporary. If 27th Street is not considered temporary, then a variance is needed to allow the cul-de-sac to be approved in excess of 800 feet as part of this plat. (c) Only 2 of the 13 Lots appeared to have at least one acre of land suitable for septic drainfields. The letter of May 15, 1987 from the City Engineer indicated that: (a) There is sufficient area available (about 10,000 sq.ft.) on each of the 13 lots to provide for two separate and distinct drainfield sites. However, it appears that the minimum 1 acre requirement has not been met. Based on this analysis, a variance would be needed to allow approval of the 13-lot plat with less than 1 acre for the two drainfield sites on 11 of the lots. 'Because of the limited area tested on each lot, the City Engineer provided a detailed lot -by -lot description of how and where septic ,drainfields should be installed. A Bruce Folz reported that their Soil Scientist Roger Johnson had taken -five soil borings and two perk tests on each lot, tested 10,000 sq.ft. -and documented everything very carefully. This information was given -,to City Engineer Bohrer. Folz added that he had measured the areas --and every one of the lots have one acre or more of unrestricted soils •or less than 30 percent. Folz emphasized that 1/4 acre is enough land area sufficient for two drainfield systems. He felt it was unreasonable to ask him to take more soil borings. He has done the majority of the developments in the City, and this development has
