Example Projects

Mr. Kindred has provided infiltration assessment services for the 6,000-acre University combined sewer basin in north Seattle for the King County Wastewater Treatment Division since 2014. Over 100 exploration have been completed for the project with shallow infiltration testing in over 50 vactor explorations and deep infiltration testing in 27 test wells. The subsurface exploration and testing program combined with publicly available boring data have been used to develop basin-wide maps of both shallow and deep infiltration feasibility. The maps have been used to estimate infiltration feasibility at over 1,000 potential locations for green stormwater facilities. 

Kindred Hydro conducted an infiltration assessment for the west Duwamish project area for the King County Wastewater Treatment Division. The project area included the South Park and Highland Park neighborhoods in south Seattle. Installation of two monitoring wells confirmed the feasibility of deep infiltration in the Highland Park neighborhood. A series of field investigations, including ten pilot infiltration tests and three groundwater monitoring wells, were conducted to confirm the infiltration feasibility in the South Park neighborhood. Groundwater modeling was conducted to estimate the rise in groundwater associated with widespread stormwater infiltration.

Kindred Hydro conducted an infiltration assessment for the East Bremerton/East Port Orchard areas of unincorporated Kitsap County. Scott assisted in preparation of a desktop assessment of infiltration feasibility and conducted field visits for 10 potential low impact development (LID) project locations. Based on this review, Scott provided an initial assessment of infiltration feasibility at the ten sites. The client/consultant team selected three project locations for infiltration field assessments. The field investigations were conducted using Kitsap County crews and provides site-specific infiltration information at a reasonable cost.

 As project manager, Scott Kindred provided hydrogeologic and geotechnical support for this 3,000 acre resort development in central Washington State. The main challenge at this site was to comply with the requirement in the site development permit to infiltrate 100 percent of stormwater runoff. In one portion of the site, Mr. Kindred developed an innovative approach that utilized a series of 70 foot deep underground injection control wells. The client was pleased with the small footprint and reasonable cost of this approach and implemented similar solutions on other portions of the site.  

Scott Kindred conducted an evaluation of the infiltration feasibility for a series of bioretention facilities in the Overlake neighborhood. This neighborhood is characterized by dense retail development and close to 100 percent impervious coverage. The assessment included subsurface explorations using a Vactor truck to minimize cost and damage to existing roadways. Our assessment concluded that the infiltration capacity was generally low and highly variable over short distances. Based on this assessment, the bioretention facilities were constructed with underdrains to maximize the treatment capacity. 

Scott Kindred was the infiltration lead for this planned motorsports park southwest of Bremerton. The goal was to either infiltrate or disperse all stormwater runoff at the site. The subsurface exploration program, which included borings, test pits, and infiltration testing, demonstrated the feasibility of stormwater infiltration across the majority of the site. Groundwater modeling was conducted to demonstrate that the increased groundwater recharge would not adversely impact the nearby landfill waste, the large onsite sewage drain field, or to wetland hydrology at the lower end of the property.
