Planning Commission Meeting Minutes – Wednesday, February 03, 2010 Page 2 Associate Planner Bryan Lloyd reviewed staff’s analysis of the request by St. 44 Paul Regional Water Services (SPRWS) to reuse the concrete from the 45 demolition of the existing reservoir in the construction of the new reservoir, rather 46 than trucking out the concrete rubble, at the Dale Street Reservoir at 1901 Alta 47 Vista Drive. The request seeks approval of a temporary concrete 48 crushing/recycling operation as an INTERIM USE, pursuant to City Code, 49 Section 1013.09. 50 Mr. Lloyd noted that the most significant issues would be noise and vibrations 51 during the crushing operations; however, he noted that there were no residents 52 within 150’ of the proposed crushing site, with the closest residence being 53 approximately 500’ from the location, so impact in the neighborhood should be 54 minimal. Mr. Lloyd advised that, to mitigate any potential noise concerns, City 55 Code stipulated hours of operation on weekdays from 7:00 a.m. – 10:00 p.m., 56 and 9:00 a.m. – 9:00 p.m. on weekends; and staff was recommending an 57 additional condition further reducing those times of operation to 8:00 a.m. – 8:00 58 p.m. on weekdays; and 9:00 a.m. – 8:00 p.m. on weekends for even less 59 interruption of residents’ mornings and evenings. 60 Mr. Lloyd noted that any potential runoff and dust were regulated by City Code, 61 through watering down of the piles as part of the process; and further monitored 62 by state level agencies. 63 Staff recommended approval of the requested INTERIM USE, based on the 64 comments and findings of Sections 4 – 6, and subject to conditions as detailed in 65 Section 7 of the staff report dated February 03, 2010. Mr. Lloyd advised that the 66 only condition still pending agreement between staff and the applicant was the 67 ending date suggested for April 30, 2010; with the applicant seeking an additional 68 two (2) weeks, until May 15, 2010, to facilitate any potential delays. Mr. Lloyd 69 further advised that staff had determined that this extension should cause no 70 major impacts to the process. 71 Discussion included the number of anticipated days required for the crushing 72 operations; completion of demolition with materials stockpiled, then crushed 73 within a contracted period of time, prior to construction of the new facility; and 74 plans of the applicant for dust mitigation. 75 Applicant Representative, John Klebeck, Short Elliott Hendrickson 76 Mr. Klebeck advised that the start date of the demolition portion of the project is 77 projected to be approximately March 1, 2010, with a bid opening scheduled for 78 February 24, and pending contract processing. Mr. Klebeck advised that there 79 was no date scheduled yet for the crushing, and would be up to the contractor, 80 but that it was anticipated to begin as early as possible, with the projected Mary 81 15, 2010 deadline for completion of that portion of the operation. 82 Discussion among Commissioners, staff and the applicant included the process 83 for demolition, crushing and use of the crushed materials for the foundation base 84 of the new reservoir; footprint of the new reservoir the same as the original; 85 height of the new reservoir, with final design still pending, but anticipated to be a 86 concrete tank with a domed top and somewhat taller than the original, with 87 bermed materials stockpiled and reused during the re-grading of area around the 88 new tank, which will project further from the ground than the original, even 89 though it capacity will be less than the original tank. 90 Mr. Klebeck advised that the original tank was constructed in 1918, stipulated 91 where the actual crushing operations would occur on site; changes to the 92 topography of the site the new construction based on gravity flow; composition of 93 materials to be crushed according to MPCA guidelines; identification of project 94 manager Steve Campbell from S.E.H. Engineering for identification of the project 95 scope; and attempts to keep the crushing operation to as limited a time as 96
