Construction Firms
Riparia serves construction firms across the Pacific Northwest to provide the environmental permitting, compliance, mitigation, and stormwater services that construction projects require, from preconstruction through project turnover.
Construction Projects that Protect the Environment
Riparia’s team drafts and implements Stormwater Pollution Prevention Plan (SWPPP) and 1200-C permit development, Certified Erosion and Sediment Control Lead (CESCL) services, Best Management Practice (BMP) installation, Spill Prevention, Control, and Countermeasure (SPCC) plan support. Whether you’re a general contractor managing environmental compliance on a complex project or a developer with an onsite mitigation obligation, Riparia brings the field experience and regulatory knowledge to handle the entire process.
Challenges Construction Firms Face
Construction projects generate environmental compliance obligations that run parallel to the construction schedule. Falling behind on them can stop work, trigger violations, incur additional project costs, and delay project closeout. Riparia has specialized expertise to keep things on budget and on schedule.

We Keep Your Project on the Critical Path
Riparia handles SWPPP development, CESCL services, and BMP management so permit compliance doesn’t become the reason your project falls behind. We understand construction schedules and work as a reliable subcontractor and partner.
We Navigate Permit Violations Fast
We have established relationships with the agencies that administer these programs and know how to move through compliance efforts efficiently. If your project receives a violation notice, Riparia steps in immediately and works directly with regulatory agencies to get things resolved.
We Get Permits Closed Out Right
Permit closeout requires demonstrating that the site has been stabilized, BMPs have been appropriately managed, and all permit conditions have been satisfied. Riparia understands what regulators need to see and how to document it—and we routinely complete closeout under budget and ahead of schedule.
Professionalism & Safety Built for Construction Environments
Trained to meet the specific safety demands of active construction environments, our team performs our work in a professional manner, prioritizing cleanliness, timeliness, and safety. We arrive when we say we will and leave the site in better condition than how we found it.
Signature Project
HARL 1-3 Swale 140 Rehabilitation — HOA, Southwest Washington
Riparia partnered with a private homeowners association to restore a stormwater treatment facility consisting of detention infrastructure and a large vegetated flow-through swale with an augmented underdrain system. The facility had experienced reduced performance due to sediment accumulation, damaged infrastructure components, and drainage issues identified during City inspections.
Following unsuccessful repair efforts by another contractor, the HOA engaged Riparia to evaluate existing conditions and develop a comprehensive rehabilitation approach to restore functionality, improve long-term performance, and return the facility to compliance.
