BACKGROUND
The City of Chino’s storm drainage network is composed of street gutter facilities, inlets, and a network of storm drain pipelines that convey runoff to various creeks and flood control channels such as San Antonio Channel, Cypress Channel, and Chino Creek. These conveyances have served as a convenient source of storm water disposal for several years, generally leading storm water runoff to the Prado Basin. The majority of existing storm drain facilities are based on a drainage master plan study prepared in 1966 for the San Bernardino County Flood Control District. In 1993, the City implemented a hydrological analysis of the master plan study area to reevaluate the existing drainage systems and develop a more up-to-date Master Plan of Drainage (MPD).
In 1998, the MPD was revised to include Subarea 1, which identified capacity expansion due to the addition of 11.25 square miles in the southwest area of the City. The study area was encompassed by Kimball Avenue to the north, Euclid Avenue to the east, Prado Basin to the south and Chino Creek to the west. Impacts to the land-use changes from solely agricultural to the combination of agricultural and industrial land developments were reanalyzed for several major segments of the City’s western storm drain system.
In 2003, the MPD was revised again to include Subarea 2 “The Preserve,” which identified capacity expansion needs due to the addition of 8.5 square miles in the southeast area of the City. The study area was defined by Ontario (New Model Colony area) to the north, Riverside County to the south and east, and Euclid Avenue to the west. Impacts to the land-use changes from the agricultural and open space to the combination of mixed land development use were reanalyzed for several major segments of the City’s eastern storm drain system. Drainage basin areas were added and redefined from the Chino Airport Master Plan and Ontario’s New Model Colony Drainage Master Plan.
In 2004 and 2007, two unofficial amendments to the MPD were prepared to update the ultimate build-out of The Preserve area. In 2022, the MPD for Subarea 2 “The Preserve” was further amended to reflect the updated drainage areas in the Preserve.
ISSUES/ANALYSIS
A comprehensive citywide update to the Master Plan of Drainage has not occurred since 1993. The MPD Update (MS251) will include a thorough evaluation of capacity deficiencies in the City’s storm drain system and determine the necessity, size, and location of future storm drains. The MPD Update will analyze the current conditions along with one-hundred percent land-use/built-out conditions of the watershed including the Sphere of Influence (SOI). The update will also address environmental compliance requirements provided by the State Water Resources Control Board (SWRCB) Trash Amendment Policy for inlet improvements in Priority Land Use areas.
On February 5, 2026, the City released a Request for Proposals (RFP No. 2026-0002) for preparing the “Master Plan of Drainage Update” via PlanetBids, in accordance with City procurement policies. The City received 4 proposals by the closing date of March 12, 2026. A review committee, consisting of City staff, evaluated proposals separately to maintain confidentiality and fairness. Staff then scored these proposals using the following weighted criteria:
• Experience/Qualifications: 20%
• Past Performance/References: 25%
• Plan Methodology/Project Approach: 25%
• Quality and Responsiveness of Proposal: 20%
• Cost Evaluation: 10%
Following evaluation, Dudek received the highest average score and is recommended for contract award.

Staff requests City Council approval to award a professional services agreement to Dudek to prepare the City’s Master Plan of Drainage Update (MS251) for a not-to-exceed amount of $464,350.
The scope of work for the Master Plan of Drainage Update will address the following:
1. Identify and prioritize inlet improvements to most effectively enhance compliance with the SWRCB Trash Amendments Policy
2. Identify and prioritize storm drain system segments where current capacity of the system is undersized and unable to convey the design storm
3. Validate and prioritize the list of Capital Improvement Projects (CIP) based on appropriate ranking criteria with justification
4. Update and validate the City’s Storm Drain Geographic Information System (GIS) layer from As-Built drawings
