Acclaimed Stormwater System Saves Developer Millions
Audie Murphy Ranch is a newly developed master planned community in Menifee, California and named after one of the most decorated American combat soldiers of World War II. Menifee is centrally located in the heart of Southern California between San Diego County and Los Angeles County. Within this new 450-acre residential development, there are a number of exclusive amenities: a brand new elementary school, clubhouse, parks/open spaces, and an eventual 1,410 private residential properties.
During the initial stages of design and construction (prior to Bio Clean’s consultation), project engineers planned for two massive bioretention systems to address the site’s drainage and stormwater treatment requirements. These initial BMPs (Best Management Practices) were not ideal solutions and presented significant construction challenges.
Each planned BMP formed two river beds or “paseos” that were intended to collect stormwater runoff from the development’s 195 acres of impervious surfaces (60 acres of streets and 135 acres of roof and driveway areas). The developer nor the contractor realized that the two paseos would not only consume 50 acres of the 450-acre property, representing 11% of the total development, almost 3-times the size of the elementary school – but after breaking ground on the trenches and river rock processing, contractors began to project months of delays at an increasing 7-figure construction cost.
The Bio Clean engineering team and veteran stormwater designers, were asked to evaluate the project’s existing stormwater management plan and provide insight. Immediately, they recognized a vastly more efficient solution. Within minutes they had formed a sketch and quote that would end up saving the developer millions of dollars, preventing further development delays. This incredible alternative solution was the Modular Wetlands System Linear (MWS Linear), shown in Figure A. Introducing the MWS Linear’s collection of advantages immediately provided substantial benefits. Overnight, the contractor was able to suspend the construction on the first of the two river beds, whose build was already underway and demanding so much rock fill that a processing plant was established on-site just to produce the millions of pounds of rock needed for construction.
As opposed to acres of custom land movement, construction time, and millions of dollars spent in labor and resources, the developers had a seemingly over-the-counter, cost-effective solution. What was prescribed is the stormwater industry’s flagship solutions and is often considered the standard for stormwater compliance. Just 18 weeks after the project’s first review and consultation, seven Modular Wetlands System Linears were delivered to the Audie Murphy Ranch development, marking an astounding 75% cost savings for the customer, but also unlocking the developer’s ability to finalize real estate occupancy permits months sooner than originally projected, and clearing them to close on new home sales.

The MWS Linear is a precast horizontal flow biofiltration system, and for years this flagship Bio Clean solution has been giving engineers and contractors the ability to save millions in valuable land while fulfilling the contractor’s demands for rapid fulfillment and installation. The Modular Wetlands System Linear also has long-term cost benefits, as it is much easier and cost-effective to maintain over time compared to non-proprietary BMPs.
Not only is the Modular Wetlands System Linear a developer’s best friend – saving millions in land and construction costs – it is a superior treatment system that protects watersheds and impaired water bodies across the country. Its high-performance media and patented horizontal flow show equivalent or better pollutant removal to standard biofiltration. The system has also been issued Full Trash Capture Certification from the California State Water Resources Control Board and it is approved by the Washington State Department of Ecology TAPE program for General Use Level Designation (GULD).
