  • Patent number: 12252875
    Abstract: A system and method for restoring wetland habitats and providing a platform on which indigenous and transplanted plant species can thrive. Water from a source, such as, stormwater run-off is captured and filtered through a combination of sand berms and riffle weirs to a series of aquatic beds, thus creating nutrient-rich environment.
    Type: Grant
    Filed: June 29, 2021
    Date of Patent: March 18, 2025
    Inventor: Keith R. Underwood
  • Publication number: 20220056684
    Abstract: A regenerative stormwater conveyance (RSC) system for treating and dispersing stormwater runoff is disclosed which includes an upstream entry point where water enters the system and an entry pool downstream from the entry point that collects water from the entry point. The RSC system includes one or more shallow aquatic beds that receive water from the entry pool in a serial manner and each of which includes a filtration structure for filtering water from the aquatic bed. Riffle weir grade control structures are positioned between the aquatic beds and transition water overflowing from each upstream aquatic bed to a downstream aquatic bed. Accordingly, collected stormwater runoff traverses the series of aquatic beds and riffle weir grading structures and is treated and safely detained, thus, conveying stormwater to groundwater through infiltration.
