Storm Drainage

CSW|ST2 can prepare storm drainage studies encompassing local areas, cities, and regions. We help clients respond to public agency requirements, such as the National Pollution Discharge Elimination System (NPDES). We also prepare and/or provide consultation on Storm Water Pollution Prevention Plans (SWPPP) and Erosion Control Plans.

Grading and Drainage

Our site designs balance cut and fill, while also providing clients with cost effective and environmentally sensitive solutions.

Water Facilities

CSW|ST2 designs regional water storage and delivery systems for both public utilities and institutional users, as well as community and individual well systems for rural projects.

Sanitary Sewers

We provide plans and profiles for residential subdivisions and commercial developments. We design septic systems for rural properties, as well as monitoring the construction and maintenance of private sewer systems. We can also prepare plans and specifications for renovation of city-wide sanitation systems (collection, distribution, and transmission).

Roadways

We plan, design, and manage roads, multi-use paths, transportation corridors, and parking facilities for commercial, industrial, and residential projects. We also plan, design, and manage roads and highways for public agencies.
