... 2.2 The site is currently used for several different activities including Ramsey County's seasonal household hazardous waste collection site, a work yard for Ramsey County's Public Works Department, a stockpile area for crushed road materials and concrete from the Larpenteur Avenue reconstruction, and a site for Ramsey County/NSP's stump grinding activities (in a tub grinder). Materials were moved into and out of this site during late hours during the emergency Mississippi River flood situation in 1997. 2.3 A five-year interim use permit for the seasonal household hazardous waste collection site on this property was issued to Ramsey County in 1996. In addition, a five-year interim use permit for stump grinding activities was issued to Ramsey County/NSP in 1997. Both of these interim use permits require annual review by the City. 2.4 A portion of the site (approximately 4.4 acres known as Lot 7) has also been considered for a family transitional housing project which would be located on the south edge of the site, adjacent to Larpenteur Avenue. This project, still in the planning stages, would include approximately 20,000 s.f. of building, with 55 rooms, housing between 55 to 62 residents, for periods averaging 11 to 12 days. Seventy percent of the residents are children; most of the families are one parent (mother) households. The project would cost over $3 million and would require a rezoning of the property and/or designation as a Planned Unit Development. New sidewalks and driveways V'voutd be installed along Larpenteur from Kent to Dale Street for this project if built on this site. An alternate site for this activity on this property site may be further west along Dale Street. 3.0 RAMSEY COUNTY PROPOSAL 3.1 Ramsey County Public Works proposes to operate the portable concrete crusher on the site from April 1 through May 15 during 1998 and 1999, and during the construction season in 2000. All of the concrete to be crushed will come from the .Larpentp.1 Jr Avemm r-coonstruction project nF1bt, with no other projects being allowed to "piggy-back" on this activity. The concrete to be crushed would be stockpiled between crushing visits, with crushed concrete being stockpiled for reuse in the concrete mixed for new roadway material for Larpenteur Avenue. Approximately 20,000 metric tons of concrete will be crushed each season, with approximately 2000 tons being crushed per day. 3.2 Concrete crushing would only be allowed during the normal work week (Monday through Friday) with hours of operations limited to 8:00 am to 5:00 p.m. The total number of crushing days will not exceed 15 days per year in 1998 and 1999, and 10 days in 2000. Water will be used to control dust during crushing operations. 3.3 Concrete batch mixing would be allowed on two separate occasions per construction season, for a period up to five working days per occasion. Batch mixing generally requires long hours of mixing and pouring during these periods. Although specific times have not been established, it is quite possible that the site would operate from sunrise to sunset. During this time, trucks would be entering and/or leaving the site every 2-3 minutes, and equipment would be used to load PF#2985 - RPCA (02/11/98) - Page 2 of 5
