Pavement History This project encompasses 4 subdivisions, all generally located in northeastern Ramsey. The streets were built at varying times between 1982 and 2001. The only subdivision which received an overlay improvement was Rodeo Hills Estates in 1998, 16 years after its construction. All streets have received two crack seal / seal coat improvements since construction, or overlay in the case of Rodeo Hills Estates, with the latest being in 2012. Maintenance crews have performed patching over the last several years, including extensive patching in 2023. More detailed information on the pavement history is included in the street segment summary attached to this case. Existing Conditions Ford Brook Estates 3rd is 0.43 miles of 30-foot wide urban section including bituminous curbing. The existing pavement section is approximately 2-inches of bituminous over 4-inches aggregate base. Storm water runoff is directed to bituminous flumes, which flow runoff through existing drainage and utility easements to stormwater basin, and eventually the surrounding wetlands. The subdivision is made up of 13 single family home lots, approximately 2 to 2.5 acres, zoned rural residential. Municipal water and sewer do not exist in the area, which is located well outside of the 2040 MUSA boundary. Rodeo Hills Estates is 1.16 miles of 24-foot wide rural section. The existing pavement section is approximately 4-inches of bituminous over 3-inches of aggregate base. The geotechnical report found much of the subdivision to have poor soils under the pavement, including silt and clay, which will require subsoil corrections. Storm water runoff is directed into drainage swales adjacent to the street, which ultimately direct runoff to the county ditch which cuts east to west across the plat, and finally to Ford Brook, which is adjacent to the east. The subdivision is made up of 41 single family home lots and one park lot which is unimproved, approximately 1 acre, zoned rural
