PROJECT NARRATIVE
RWY 9-27 RSA Improvements:

The Runway 9-27 RSA Improvements Project is intended to reduce the maintenance of the existing RSA along the north side of the runway, which erodes during storm events carving into the required 150 feet RSA. The Project area starts at Runway 27 end aiming point markings and it ends before reaching Runway 16-34. The Project goal is to solve the significant erosion issues caused by runoff coming from the north parking facility and to safely convey upstream flows coming from an existing culvert under Central Avenue. The proposed Project may consist of several improvements including: importing and utilizing surplus soils from excavation for embankment in the RSA; stabilization of areas within the RSA; grading to channelize and collect runoff to direct it towards controlled downslope conveyances; and lining conveyance with a shallow valley gutter channel.

PROJECT DESCRIPTION
This Scope of Services details the preliminary design, 90% design, final design, and bid administration services to be provided by Mead & Hunt, Inc. (Consultant), for the Runway 9-27 Runway Safety Area (RSA) Improvements Project (Project) at the Riverside Municipal Airport (Airport) for the City of Riverside (Owner / Sponsor).

BACKGROUND
The Runway 9-27 RSA Improvements Project is intended to reduce the maintenance of the existing RSA along the north side of the runway, which erodes during storm events carving into the required 150 feet RSA. The Project area starts at Runway 27 end aiming point markings and it ends before reaching Runway 16-34. The Project goal is to solve the significant erosion issues caused by runoff coming from the north parking facility and to safely convey upstream flows coming from an existing culvert under Central Avenue.

The proposed Project may consist of several improvements including: importing and utilizing surplus soils from excavation for embankment in the RSA; stabilization of areas within the RSA; grading to channelize and collect runoff to direct it towards controlled downslope conveyances; and lining conveyance with a shallow valley gutter channel.

This Project was identified in the Airport Capital Improvement Plan for Riverside Municipal Airport, dated October 23, 2023, prepared by the Airport. The Project area is expected to vary slightly based on actual observed areas of erosion along the RSA.

The estimated construction budget for the Project is approximately Two Million Dollars ($2,000,000). This Project is anticipated to be funded by a FAA Airport Improvement Program (AIP) grant, California Grant, and local funds. The Project will be designed to meet FAA standards and will be assembled as a single bid package. Mead & Hunt, Inc. is the prime consultant and is hereinafter referred to as “Consultant.” This Scope of Services was developed by the Consultant with input from the Owner, and the FAA.

PROJECT ELEMENTS
This Project includes engineering design and development of construction documents for the grading and drainage improvements along the north RSA for runway 9-27. The proposed grading improvements will be designed to meet Advisory Circular (AC) 150/5300-13B, Airport Design, requirements, and the proposed drainage improvements will be designed per AC 150/5320-5D, Airport Drainage Design. Additionally, soil stabilization techniques will be implemented to prevent soil erosion. A Project graphic depicting these elements is included as Attachment 1.
