Attachment E Planninq File 10-001 . Request by St. Paul Regional Water Services for approval of concrete recycling as an INTERIM USE at the � Dale Set Reservoir, 1901 Alta Vista Drive 4 Chair poherty opened the Public Hearing for Planning File 10-001 at 6:37 p.m. 5 Associate Planner Bryan Lloyd reviewed staff's analysis of the request by St. Paul Regional Water Services 6 (SPRWS) to reuse the concrete from the demolition of the existing reservoir in the construction of the new ; reservoir, rather than trucking out the concrete rubble, at the Dale Street Reservoir at 1901 Alta Vista Drive. The b request seeks approval of a temporary concrete crushing/recycling operation as an INTERIM USE, pursuant to 9 City Code, Section 1013.09. 10 Mr. Lloyd noted that the most significant issues would be noise and vibrations during the crushing operations; 1� however, he noted that there were no residents within 150' of the proposed crushing site, with the closest 1: residence being approximately 500' from the location, so impact in the neighborhood should be minimal. Mr. Lloyd 1: advised that, to mitigate any potential noise concerns, City Code stipulated hours of operation on weekdays from 14 7:00 a.m. — 10:00 p.m., and 9:00 a.m. — 9:00 p.m. on weekends; and staff was recommending an additional 15 condition further reducing those times of operation to 8:00 a.m. — 8:00 p.m. on weekdays; and 9:00 a.m. — 8:00 1E p.m. on weekends for even less interruption of residents' mornings and evenings. 1 i Mr. Lloyd noted that any potential runoff and dust were regulated by City Code, through watering down of the 18 piles as part of the process; and further monitored by state level agencies. 1� Staff recommended approval of the requested INTERIM USE, based on the comments and findings of Sections 4 2c — 6, and subject to conditions as detailed in Section 7 of the staff report dated February 03, 2010. Mr. Lloyd 2�� advised that the only condition still pending agreement between staff and the applicant was the ending date 22 suggested for April 30, 2010; with the applicant seeking an additional two (2) weeks, until May 15, 2010, to 23 facilitate any potential delays. Mr. Lloyd further advised that staff had determined that this extension should cause 24 no major impacts to the process. 25 Discussion included the number of anticipated days required for the crushing operations; completion of demolition 26 with materials stockpiled, then crushed within a contracted period of time, prior to construction of the new facility; 2' and plans of the applicant for dust mitigation. 2� Applicant Representative, John Klebeck, Short Elliott Hendrickson 2� Mr. Klebeck advised that the start date of the demolition portion of the project is projected to be approximately 3c March 1, 2010, with a bid opening scheduled for February 24, and pending contract processing. Mr. Klebeck 3�� advised that there was no date scheduled yet for the crushing, and would be up to the contractor, but that it was 32 anticipated to begin as early as possible, with the projected Mary 15, 2010 deadline for completion of that portion 33 of the operation. 3� Discussion among Commissioners, staff and the applicant included the process for demolition, crushing and use 3� of the crushed materials for the foundation base of the new reservoir; footprint of the new reservoir the same as 3E. the original; height of the new reservoir, with final design still pending, but anticipated to be a concrete tank with a 37 domed top and somewhat taller than the original, with bermed materials stockpiled and reused during the re- 38 grading of area around the new tank, which will project further from the ground than the original, even though it 39 capacity will be less than the original tank. 40 Mr. Klebeck advised that the original tank was constructed in 1918, stipulated where the actual crushing 41 operations would occur on site; changes to the topography of the site the new construction based on gravity flow; 42 composition of materials to be crushed according to MPCA guidelines; identification of project manager Steve 43 Campbell from S.E.H. Engineering for identification of the project scope; and attempts to keep the crushing 44 operation to as limited a time as possible during the spring before windows/doors are opened to keep impacts 45 minimal for the benefit of the neighbors. 4E Further discussion included materials and/or chemicals that may be or may have been stored in the gatehouses, 47 also scheduled for demolition, with roofing and brick materials proposed to be trucked off-site and not reused; 48 electrical service nodes and alarms as part of the SCADA system for the City of Roseville and St. Paul Regional 4� Water Services (SPRWS); and recommendation of Commissioner Wozniak to contact Ramsey County 5c Environmental Health prior to demolition of the gatehouses to facilitate disposal of fluorescent lighting and other 5� hazardous wastes in the gatehouses. 5� Mr. Paschke advised that, as standard practice, Ramsey County was notified by staff during the permitting 5' process.
