Surface Water Resources

With an ever changing regulatory environment, communities are increasingly faced with managing the effects of urban development, and are responsible to design and implement measures to preserve and improve these surrounding water bodies.

TKDA works closely with our clients to develop and implement practical, cost effective stormwater facilities. Designs are balanced to minimize costs while providing flood control, enhancing water quality, and protecting water resources.
