TO: Don Ashworth, City Manager � � 6 - i 4 - g - I Date Submitted to Commfsstod FROM: Paul Krauss, Planning Director Date Subr tted to Council 1 DATE: May 13, 1992 ,c` i R SUBJ: Proposed Ordinance Amendment Pertaining to Modifications to the 1 Mining, Earthwork and Zoning Codes, First Reading yi. In 1990, the city adopted an extensive revision to the ordinance dealing with all aspects I of mining and grading activity. In general, these regulations have worked well and are involved in the ongoing litigation and review of :the Moon Valley Gravel operation. We have also used the ordinance extensively to review three or four other major grading or 1 mining operations. Perhaps the biggest impact to the ordinance was the additional regulatory authority and standards that were provided for the hundreds of smaller scaled grading operations that occur throughout the community. The ordinance regulates all 1 activities that move more than 50 yards so that even significant regrading of a back yard that may for example impact area drainage patterns, is now subject to a permit. 1 While the ordinance has proven generally to be successful, we have found that it needs correction in one area. Under current language in the ordinance, the city's ability to I allow grading and regulate same in many zoning districts is in question. We have come . to the realization that under current ordinance language, any time more than 50 cubic yards of earth is moved, it is technically in violation of the code unless it occurs in the I agricultural districts where grading and mining activity is specifically allowed. This was not the intention of the ordinance, nor is it the way in which we have been administering it over the past two years. Rather its intent was that mining activities be restricted to the I agricultural districts, but that grading is a normal occurrence in a developed or developing community and that this should be allowed. Grading and altering between 50 and 1000 cubic yards is processed administratively, for over 1000 cubic yards, an I excavation permit or interim use permit is required. The City Attorney has prepared modifications to the code that correct this omission. He is also proposing to eliminate a section of the code that is redundant since the adoption of our new grading standards 1 two years ago. 1 �a PRINTED ON RECYCLED PAPER I 1 1 Don Ashworth May 13, 1992 1 Page 2 1 The proposed amendments are fairly straight forward but would have a significant benefit on supporting existing administrative procedures on processing grading permits as well as the flexibility to grade sites in an acceptable manner located anywhere in the I community; In separate actions, the Planning Commission is being asked to review two grading permit requests that happen to occur in the IOP and RSF Districts. Staff believes that both requests are reasonable and meet the standards in the ordinance. 1 However, the correction proposed by the City Attorney is required to be approved before these actions can be initiated. 1 PLANNING COMMISSION ACTION The Planning Commission unanimously recommended approval of the ordinance 1 amendment as proposed by staff. I STAFF RECOMMENDATION Staff recommends that the City Council approve first reading for an amendment to I Section 20 -1351 of the Chanhassen City Code and repeal Sections 20 -1352 through 20- 1384.

That association has Minutes from their meeting authorizing them to use 4 boats. ' Emmings: You already won Tim. She's just stating her position. Erhart: I know. Batzli: Anything else Joan? Ahrens: And that was their use in 1981 and I think that's what we should ' go with instead of making something up out of the blue. Erhart: I'm trying to understand this Steve too. This is very confusing. Batzli: Steve, do you have anything? Emmings: I think this case is different again because we have a document here that shows what they were proposing to do. I think it's reasonable. I think we're running a risk here of getting way too strict and legalistic. Oh, the picture shows 2 boats, so it's 2 boats. Now in some cases those 2 ' boats might be reasonable and for some of the reasons Ladd outlined, that might be reasonable on this lot but it just, I have a little different opinion there. I think 4 boats is okay on this lot and that's what I would I grant. That's all. Batzli: My sentiment is not that I don't care as much what their intent was. I think we can regulate and like Tim said, but I at least take the evidence that they were able to present at it's face value and what they were telling us so that's why I would give them 3. Other than that, I agree with the motion. It's the number of boats that's the issue. Okay, 1 this will go onto City Council when? Aanenson: May 18th. ' Batzli: May 18th so please follow the issue to the City Council. They will make the final determination. Thank you for coming in. PUBLIC HEARING: ZONING.ORDINANCE AMENDMENT TO AMEND CHAPTER 20 OF THE CITY CODE PERTAINING TO MINING AND EARTH WORK. Sharmin Al -Jaff presented the staff report on this item. Chairman Batzli ' called the public hearing to order. There was no one present wishing to speak on this item. Erhart moved, Emmings seconded to close the public hearing. All voted in favor and the motion carried. The public hearing was closed. 1 Batzli: Any discussion? Anyone have any comments? Is there a motion? Planning Commission Meeting 11 May 6, 1992 - Page 44 Erhart moved, Emmings seconded that the Planning Commission recommend to approve an amendment to Section 20 -1351 of the Chanhassen City code and repeal Sections 20 -1352 through 20 -1384. All voted in favor and the motiorl carried unanimously. PUBLIC HEARING: 1 INTERIM USE PERMIT FOR GRADING /EXCAVATION LOCATED AT LOT 5, VINELAND ADDITION. FORTIER AND ASSOCIATES. Public Present: Name Address 1 • Daryl Fortier 408 Turnpike Road, Golden Valley Jim & Mary Stassen Peaceful Lane and Pleasant View Road Sharmin Al -Jaff presented the staff report on this item. Chairman Batzli called the public hearing to order. Daryl Fortier: First, I'm Daryl Fortier representing Frank Beddor, Jr. He is purchasing the property from Mr. Owens. We're in agreement, I'm in agreement with the staff report. All 16 conditions of 17. The only one I 1 would like to discuss is point number 10 which says there shall be an emergency overflow swale constructed to the southwesterly portion of the 4 site to drain across Peaceful Lane. This would, for a swale to work as yo all understand. This allows water to pass over the surface of the ground. The surface of the ground at that point is controlled by the elevation of Peaceful Lane which is about 1005. Our 100 year storm is at about 995.5. For us to get a swale to go up another 5 feet would require us to have eight 100 year floods. Eight 100 year rains in a row. That is concurrently before the water would get that high. Emmings: What's your point? Daryl Fortier: My point is we don't think that's a viable idea. We think 1 that it's a good idea for lots that work but it won't apply to this lot. I think a more reasonable way of controlling an overflow situation here is to provide a second pipe which would be normally set at the 100 year elevation' such as if the first pipe to outlet the pond ever did become obstructed, that as the water rose to the 100 year elevation, it would then flood into this other overflow pipe and allow us a secondary means of draining the lot. It's just a detail to work out with engineering. , Emmings: The engineer is nodding. You've already won. Daryl Fortier: Okay. That's the sole issue. Batzli: This is a public hearing. Would anyone else like to make a comment on this issue? Mary Stassen: My name is Mary Stassen and Jim and I live at the corner of Peaceful Lane and Pleasant View Road right across from the construction work that they'll be doing.
