LAKE ELMO CITY COUNCIL MINUTES NOVEMBER 3, 1987 PAGE 8 Since Ruth's First Addition was platted during a period of low water, the lot lines now extend out into the water. It appears that the Eisele's excavation will be performed on the portion of their property which is in the flood plain. Bohrer has no objection to the permit, but offered the following comments: 1. The north line of Lot 4 has an angle point and changes directions just east of Eisele's house. This lotline is not able to be sighted by eye. To prevent the construction of the channel from going off the Eisele's property, he recommends that the north line of Lot 4 be established in the field by a surveyor so that the permitting agencies can see that the channel remains on the Eisele's property. 2. The Eisele's propose to erect a silt fence or hay bale dikes to enclose the dredge spoil until it dewaters. These dikes shall remain in place until turf is established on the spoil to prevent erosion. M/S/P Graves/Johnson - approve the request by John Eisele, 3141 Klondike Avenue, for a permit to work in protected waters; contingent on the two conditions indicated in Larry Bohrer's letter dated November 2, 1987. (Motion carried 4-0<Armstrong was not present to vote). B. Browns Creek Surface Water Management Plan The Browns Creek Watershed includes a one-half square mile (quarter section) area in the NE corner of Section 1 in the NE corner of Lake Elmo, near the intersections of Co. 15/Manning Avenue and Trunk Highway 36. City Engineer Bohrer reviewed the Water Management Plan for impact on these 160 acres and his comments are listed in his letter dated November 2, 1987 to the City Council. Bohrer stated in his letter that the policies and goals of this Water Management Plan are very close to the way Lake Elmo has been doing things for years. In fact, the City -adopted "1% Rule" is slightly more restrictive than the Brown's Creek Plan. The City will have to pay a little more attention to water quality by adopting rules limiting soil loss and enacting some type of septic system inspection. The Brown's Creek Water Management Organization is soliciting local comments on the Plan. The only objection Bohrer found was with Water Quantity Policy 1D on page 29, which states: "Stormwater management improvement on existing and new systems shall be designed on the Gritieal storfn event for shall not be less than a one-in-100-year frequency storm event (5.9 inches in 24 hours)."
