Sanitary Sewer There was 177,390 feet, or 33.6 miles, of sanitary sewer cleaned in 2012. In addition, there was approximately 10 miles of sanitary sewer trunk televised and inspected including trunk mains in Area E and F of the street program. Many of the vulnerable sewers in Area E were replaced or lined in 2012 with the street project. Public Works did not have any emergency sewer trunk repairs during 2012 but did respond on a few occasions a troublesome manhole in Area E that was found to have dropped a few inches in elevation and not allowing sewage to flow positively down gradient. The manhole was replaced and no further problems have been reported. City -owned rain garden on Groveland Road Stormwater Maintenance for over 250 infiltration basins constructed with the street projects has increased the workload for the stormwater O&M. The challenge for long-term performance of these basins involves keeping sediment out of the basin bottoms where the infiltration occurs. Over time, fine sand and silt carried by storm runoff will build up in the basin bottoms causing infiltration rates to drop. The grass strip at the curb cut is meant to intercept the sediment before reaching the basin infiltration area, and requires removal by maintenance personnel. Sediment inlets to Silverview Pond were dug out during fall 2012. Pond maintenance and inspection procedures have increased and will continue in 2013. Streets and Trails The fourth snowiest winter of all time for the region was following by one of the least snowiest during 2011/2012. There were 20 total snow events requiring 211 tons of salt and 2,602 plow truck miles driven. This effort was split nearly 50/50 between the first part of 2012 and the last part of 2012. Maintenance crews also used 321 tons of asphalt to fill potholes, skim coat, patch, or repair various pavements. The crew also sealed cracks in the pavement during fall 2012 and painted crosswalks and pavement markings during summer. Public Works contracted with Ramsey County to paint 57,195 feet of lines to municipal streets. Parks and Facilities A wet and warm spring followed by drought conditions during summer and fall made 2012 a challenging year to keep the parklands and building grounds looking good and well groomed. Countless hours were spent mowing early on, then followed by watering trees and weeding. The maintenance crew was also busy dragging ball fields, weed whipping, maintaining landscaping, and keeping equipment in good working order. Public Works crews also performed the infield grading for the reconstructed baseball field at Lambert Park and assisted with the baseball field fencing, playground replacement, new irrigation system, and grading. 2012 ANNUAL REPORT I DEPT.
