FISCAL YEAR 2021–2022, VARIOUS LOCATIONS
City of Chino
Completion Date: 2022
RKA Consulting Group served as the prime consultant for the design and engineering of the SN211 Alley/Sanitation Rehabilitation Project for Fiscal Year 2021–22 in the City of Chino. The project focused on the reconstruction and rehabilitation of multiple alleys between Central Avenue and Benson Avenue, specifically targeting Alley 20 and Alley 21, to improve accessibility, drainage, and overall infrastructure resilience.
RKA’s responsibilities spanned the full design cycle—from initial investigation and utility coordination to engineering design and construction support. The improvements included asphalt pavement reconstruction, reconstruction of alley intersections to achieve ADA compliance, fire hydrant head upgrades, and street profile design to improve alley drainage. RKA incorporated installation and replacement of concrete longitudianal gutters into the improvement plans to improve poor drainage conditions and ensure long-term durability.
The project included the installation of over 50 ADA-compliant ramp locations, with special design attention to conflicts involving fire hydrants, utility poles, and encroaching block walls. Where necessary, hydrants and poles were repositioned to achieve ADA clearance without requiring permanent easements. RKA leveraged its familiarity with the area to anticipate design conflicts and expedite utility coordination.
As part of its comprehensive approach, RKA partnered with Kelsoe & Associates to perform topographic and control surveying, and with Converse Consultants to conduct pavement coring and subgrade soil classification across 17 locations. The resulting geotechnical analysis directly informed the pavement repair strategy, balancing construction costs with the City’s drainage and accessibility goals.
Key elements of RKA’s services included:
- Topographic surveying and right-of-way mapping
- Utility coordination with conflict resolution
- ADA ramp and sidewalk redesign at alley intersections
- Pavement rehabilitation design based on core sampling and drainage modeling
- Fire hydrant and water meter relocations where necessary
- Cost estimating and phasing options to align with budget constraints
- Construction support, including plan clarifications, addenda, and as-built documentation
All deliverables, including 30%, 60%, 90%, and 100% design packages, were submitted on time and in close coordination with City staff. RKA’s quality control process included internal cross-checks of utility conflicts, existing condition verification, and constructability reviews.
