proposed replaced with RCP. Pavement History The streets within Fox Ridge Estates 1st & 2nd subdivision were built in 1991. The street received crack seal / seal coat improvements in 1996 and 2007. Public Works Staff has performed patching over the last several years. In 2023 several intersections were included in the high priority mill and overlay improvements, in 2024 the streets were included in the skim patching project. GPR was performed on the streets in 2020, at that time the street averaged 2.5 to 2.9 inches of bituminous over 3.3 to 4.2 inches of aggregate base. Due to the skim patching, an additional 0.5 to 0.75 of bituminous covers the streets. Proposed Improvements Staff review of the geotechnical report found generally sandy subsoil make up approximately two-thirds of the roadway embankment. The eastern and northern portion of the project will require subsoil corrections due to silt and clay within the roadway embankment. The subsoil corrections will be addressed by placing a 1-foot sand section on top of geotextile fabric. This method, which has become the typical soil correction section used on City projects, also requires drain tile to be placed on top of the fabric, to properly drain the pavement section. Staff observes the subgrade material as it is being excavated, and can adjust the subsoil correction areas based on conditions found in the field. The bituminous curbing is proposed to be replaced with surmountable concrete curb and gutter. At driveways, a curb cut similar to what is typically placed in B-Style curb will be placed, to avoid high transition from the roadway to driveways. A review of the existing storm sewer was performed, and the existing storm sewer inlet locations are not proposed to change, though structures will be replaced as necessary. Where storm sewer outlets to the wetlands are located at the top of slope, the project is proposing to extend the outlets as close to the normal water level as practical, this will reduce erosion issues. Restoration of the impacted boulevard areas will include a minimum of 4-inches topsoil and hydroseed with a residential turf seed mix. Though the pavement is generally going back to the same location and elevation, driveway aprons will be replaced to match into the new bituminous pavement as minor changes will occur. In general, driveway aprons will be going back 6 feet to tie the driveways into the new curb and gutter. At the request of the Parks Department, the project includes creating parking stalls at the northeast corner of Potassium Street for future access to the Trott Brook Cemetery. A curb cut will be installed, but a trail or drive to the cemetery is not proposed with this project. The parking stalls and future access are located at City -owned property.
