Willdan has provided superior engineering and planning consulting services for close to 50 years. During that time, Willdan has earned an outstanding reputation as problem solvers by successfully delivering comprehensive, yet tailored, solutions to meet the specific needs of municipalities, counties, and special districts—as well as state and federal agencies—throughout California, the Southwest, and nationwide.

Combining an integrated approach with state-of-the-art technical resources, depth of staffing, and services that are both wide ranging, yet complementary, Willdan supports all phases of project development from concepts and financing through final design and construction. Throughout these phases our emphasis is on strong project management, cost effectiveness, timely performance, and consistent reciprocal communication—both with our clients and among our internal and external resources. Our experts and engineering professionals are adept at communicating their practical knowledge and technical expertise across disciplines in pursuing the most practical and effective solution for each project.

Willdan's broad array of engineering and design capabilities encompasses city and special district engineering, contract staffing, urban and regional planning, environmental planning, plan checking, building and safety, program/construction management, public works inspection, disaster recovery, and infrastructure design including structural, roads and highways, traffic and transportation, water and wastewater, flood control and drainage, survey and mapping, GIS, geotechnical and earthquake engineering, and landscape architecture. Specialties of particular interest to our municipal clients and public agencies include grant application assistance, National Pollutant Discharge Elimination System (NPDES) coordination and compliance, and American with Disabilities Act (ADA) analysis and compliance.

Specialty areas within our engineering and planning sectors include:

Contract Staffing and Planning. Our understanding of the needs and challenges facing public agencies is unmatched in the industry. Willdan's professionals often serve to extend our clients' staff as city engineers and other public agency positions ranging from full-time, in-house staffing to interim or part-time assistance. Additionally, a significant portion of our staff has served in public agency management positions prior to joining Willdan, infusing our organization with an in-depth understanding of the issues driving local governments. Regional and satellite offices are specifically networked and strategically located to offer local, focused service to the varied demographics of our public agency customers. Consequently, Willdan's ability to develop innovative yet practical solutions specifically adapted to the needs of individual communities remains unsurpassed.

Consulting engineering and construction support services are provided to public agencies for capital improvement projects, and to private developers for major civil and commercial/ industrial projects, or as third-party reviews.

Major Infrastructure. Federal and state funding for new infrastructure projects is drying up rapidly, leaving public private partnerships and local funding as the primary mechanisms for transportation and large-scale infrastructure projects. Willdan's depth of experience in helping cities govern locally provides a critical value to large programs during this time of change. Our intimate knowledge of city and agency cultures ensures that local concerns are addressed early in the process, avoiding costly delays to project delivery.

Our highly experienced team encompasses many technical disciplines and programs including human health and ecological risk assessment, toxicology, chemistry, geochemistry, geology, hydrology, hydrogeology, chemical engineering, environmental engineering, environmental planning, hazardous materials and waste management, surface/storm water management, and environmental compliance.

Willdan develops and implements comprehensive energy solutions nationwide for utilities, commercial entities, and all levels of government.  We help our clients realize cost and energy savings by tailoring solutions that serve vertical markets such as data centers, healthcare, lodging, and schools; providing energy reduction plans for large end-user commercial facilities and multi-family residences; and developing and implementing cutting-edge cost-effective measures for small businesses.
