Title

East Valley Parkway and Midway Drive Drainage Improvement Project - PL24-0257

Description

The proposed East Valley Parkway and Midway Drive Drainage Improvement Project (hereafter referred to as “proposed project” or “project”) would involve increasing the capacity of the storm water drainage systems in the central portion of the city. The existing storm water drainage systems in the project area are undersized and unable to collect and convey anticipated flow rates, resulting in more than 1,600 properties being completely or partially within a Federal Emergency Management Agency (FEMA) 100year floodplain. Localized flooding occurs within the project area and has triggered deployment of sandbags and road closures an average of five times per year since 2019. The proposed project would involve the construction of: • Approximately 16,700 linear feet of reinforced concrete box culverts beneath existing roadways and adjacent public rights-of-way (e.g., sidewalks), • Approximately 4,400 linear feet of reinforced concrete pipelines beneath existing roadways and adjacent public rights-of-way (e.g., sidewalks), and • Four new points of connection for storm water to enter Escondido Creek within the project site. The culverts would range in size from a single 6-foot by 4-foot culvert (24 square feet in area) to a dual 12-foot by 10-foot culvert (240 square feet in area). The pipelines would be 36 inches in diameter (approximately 7 square feet in area) and 54 inches in diameter (about 16 square feet in area). The project would require relocation of some existing underground utility lines to accommodate the proposed storm water drainage culverts. After relocation of existing utilities and installation of the proposed storm water drainage culverts and pipes, the affected roadways/sidewalks would be resurfaced. Road resurfacing would include the provision of storm water drainage inlets along both sides of the roads to collect runoff. The proposed storm water drainage improvements would provide filtration and treatment of runoff before discharging into Escondido Creek pursuant to state and regional water quality requirements. The proposed culverts/pipes would be installed beneath existing public rights-of-way primarily associated with roadways and sidewalks, including segments of North Midway Drive, South Midway Drive, East Lincoln Avenue, East Mission Avenue, North Citrus Avenue, North Rose Street, East Grand Avenue, East Washington Avenue, Daisy Street, and an unnamed alley immediately south of East Washington Avenue and north of Escondido Creek, between North Rose Street and Begonia Street. Construction of the proposed project is anticipated to commence in the first quarter of 2026 and be completed in approximately 24 months.
