Snow Drop Road Improvement Project
Document Type
MND - Mitigated Negative Declaration

Document Description
The proposed project consists of improvements to approx 2.1 miles of roadway and associated drainage improvements. These improvements will be to approx 1.3 miles of Snow Drop Road between Archibald Ave to the west and Haven Ave to the east, approx 0.5 miles of Archibald Ave south of Snow Drop Road, and approx 0.3 miles of Haven Ave south of Snow Drop Rd within the city of Rancho Cucamonga SOI, in unincorporated San Bernardino County. Currently, portions of the existing roadway are partially paved. The purpose of the project is to improve the conditions of these roadway segments in order to provide adequate access for the residents in the project vicinity. Improvements involve paving or repaving within the project roadway segments (up to 26 ft wide), installation of metal guard rails along portions of the project roadway, and installation of drainage culverts and accessory facilities to convey storm water under the roadway. Four Arizona Crossings will also be constructed in Snow Drop Road. An Arizona Crossing is a roadway crossing that allows water to overflow directly onto the roadway during storm events and includes drainage culverts under the road to convey storm water across. Drainage culverts are included in the project design of the Arizona crossings.
