Biofilter: Sunset Valley City Hall
Glenrose Engineering designed one of the first biofilter systems in central Texas, and established many biofilter design standards. Because of their efficiency and ease of maintenance, biofilters are currently a preferred storm runoff treatment option in many kinds of urban areas.
Biofilter: Sunset Valley Homestead Shopping Center
Glenrose Engineering was the preliminary engineering designer for a combined biofiltration and wet pond to treat storm runoff from the 30-acre shopping center. The design was presented as an alternative to strict compliance with pollution removal standards; and to meet the developer’s requirement for an aesthetic amenity. Key project elements included:
- integration of pond and biofilter elements to maximize performance;
- plant selections to reduce excessive nutrient loads, enhance aesthetics; and
- a rain water catch system to enhance creek baseflow.
Biofilter: Lundelius tract
This City of Austin retrofit project cleans up polluted storm runoff before it recharges Barton Springs/Edwards Aquifer. The storm runoff treatment system uses a unique combination of:
- sedimentation;
- biofiltration; and
- vegetated filters.
Biofilter: Fort Branch Creek, East Austin
Glenrose Engineering performed preliminary and design calculations for two biofilter systems to treat storm runoff. Project design required:
- completion within strict grade;
- available space constraints; and
- accommodation an existing residential neighborhood.
