Rice Creek Watershed <br />November 29, 1999 <br />John Powell, City Engineer <br />City of Lino Lakes <br />600 Town Center Parkway <br />Lino Lakes MN 55014-1182 <br />Subj: Oakbrook Peninsula <br />Dear Mr. Powell: <br />3585 N. LEXINGTON AVENUE , SUITE 330 <br />ARDEN HILLS, MINNESOTA 55126-8056 <br />PHONE (651) 766-4191 • FAX (651) 766-4196 <br />www.mnwatershed.o <br />drewrO0'l @tc.unln:ed <br />ce.htm <br />ry <br />Board of Managers <br />Regular Meetings: <br />2nd and 4th Wednesdays <br />at Shoreview City Hall <br />Proposed Easement Vacation; RCWD Permits #90-14, 92-171 & 93-167 <br />KATE DREWRY, District Admin. <br />BONITA TORPE, Admin. Assist. <br />The District Engineer has completed his review of the supplemental information provided by Robert Adamson, and a copy of his <br />report and findings (dated 11/17/99) is enclosed. In summary, it appears that the District's compensatory storage requirement <br />has been fulfilled, although not in the manner specified in the original grading plan and permit. <br />At this point, we do not see a need to regrade the entire easement area to bring it into conformance with the original grading <br />plan. However, we do recommend that the swale from the Schwartz property line to the pond be regraded as discussed in the <br />enclosed report. <br />With regard to the proposed easement vacation, as a minimum, easement should be retained over the existing pond, the <br />drainage swale and any area below Otter Lake's HWL of 912.9. We feel that any decisions relative to vacation of other <br />portions of the easement are best left to the City as we understand that there are a number of ancillary issues unrelated to the <br />District's permit requirements. <br />Lastly, we would point out that our findings relative to compensatory storage are based on the survey information furnished by <br />the developer. Since the survey was prepared by a reputable Registered Land Surveyor, we have no reason to question its <br />accuracy. However the Schwartzes have pointed out discrepancies between the E.G.Rud survey and a survey done by <br />Advance Surveying and Engineering, and have requested further verification of the elevation data upon which the <br />compensatory storage calculations are based (refer to letter dated 11/2/99 from the Schwartzes which you were previously <br />copied on). We must advise that the District is not in a position to provide such verification and leave it to the City to determine <br />if you feel it is appropriate. <br />Please let me know if you have further questions on this matter and keep us appraised of its final disposition. <br />Sincerely, <br />Kate Drewry <br />District Administrator <br />bct <br />Enclosures: 1 <br />c: Paul & Julie Schwartz, 2140 Otter Lake Dr., White Bear Lake, MN 55110 <br />Elizabeth Melton, 2150 Otter Lake Drive, White Bear Lake, MN 55110 <br />Robert Adamson, 6001 Sargent Court N., White Bear Lake, MN 55110 <br />Derek Knapp, PE, Montgomery Watson Engineers <br />Board of Managers (5) <br />Correspondence <br />RCWD File #93-167 <br />A.J.
