36th Avenue Road Rehabilitation Project

Received
Present Land Use
The project does not have a specific land use designation, as it focuses on rehabilitating an existing roadway.
Document Description
The proposed project consists of the rehabilitation/improvement of approximately 600 linear feet of 36th Avenue between Phillips Avenue and Eureka Avenue. The project is intended to improve roadway safety, access, drainage and infrastructure reliability. Key components of the project include:
Grading and Earthwork: The roadway will be re-graded to establish a uniform profile and improve drainage. This may involve the importation of up to 500 cubic yards of fill material (may exceed 500 cubic yards if necessary) to raise low points and achieve the desired elevation and slope necessary for proper roadway function and stormwater management. The existing roadway will be raised approximately one foot.
Roadway Reconstruction: The existing roadway surface will be removed and replaced with new structural sections. This includes the placement of aggregate base rock and a new layer of hot mix asphalt to provide a durable and safe driving surface. Edge treatments, such as paving transitions or shoulders, may be included depending on site conditions. Roadway improvements will adhere to all applicable Federal, State and local agency requirements.
Drainage Infrastructure: To enhance stormwater conveyance and mitigate localized flooding, the project proposes the installation of new drainage features, including culverts, within an existing blue line waterway. Approximately 600 linear feet of the seasonal waterway will be modified to accommodate an enclosed culvert system. This will involve minor dredging and reshaping of the channel to facilitate proper placement of the culverts. Following installation, the area will be backfilled, graveled, and paved to restore surface conditions. Note: The project will not alter or reroute the existing course of the waterway; all improvements will occur within the current channel alignment.
Construction activities will be conducted in compliance with all applicable local, state, and federal regulations, including best management practices (BMPs) for erosion control and stormwater pollution prevention. Temporary traffic control measures will be implemented to ensure the safety of both the public and construction personnel throughout the duration of the project.
