Section 3. Project Understanding and Approach
Project Understanding
Dost Engineering recognizes the Washington Street Sidewalk Improvements and Avenue
50 Sidewalk Improvements Project as a critical initiative aimed at improving pedestrian
safety, accessibility, and infrastructure durability within the City of La Quinta. These
improvements will enhance connectivity, ensure ADA compliance, and mitigate existing
structural challenges, such as degraded retaining walls and garden walls.
Key considerations for this project include:
Utility Coordination – The proposed meandering sidewalk on Washington Street
requires close coordination with utility companies to avoid conflicts with existing
utilities and palm trees.
ADA Compliance – The curb ramp replacement at the Village Shopping Center
and sidewalk improvements must align with ADA guidelines to ensure
accessibility.
Structural Integrity – The retaining walls along both project locations require
thorough assessment, with cost-effective and sustainable rehabilitation solutions
integrated into the design.
Aesthetic and Functional Considerations – The new sidewalks must seamlessly
integrate with existing infrastructure, including landscaping and irrigation
modifications along Avenue 50.
Stakeholder Collaboration – Engaging with City staff, Montero Estates HOA, and
utility companies is essential to achieving a design that meets regulatory
requirements while addressing community concerns.
