Twin Brooks Surplus School Site
The Twin Brooks site at 11341-12 Avenue has been approved by City Council for First Place housing.
As part of the First Place implementation program, soil tests are conducted on the site to ensure suitability for development. This testing is followed by a community open house with City staff on hand to answer residents' questions, and to collect the names of six or eight community volunteers to work with the City and builder in designing the new homes.
As there are multiple sites at different stages of development around Edmonton, the City schedules open houses well in advance to accommodate overall timelines and the needs of each community.
A community open house was planned for 2017. However, the City plans to meet with Twin Brooks residents earlier to address their concerns. Invitations will be sent to all Twin Brooks residents.
In the meantime, the City has compiled a summary of responses to questions about the surplus school site development posed by the Twin Brooks Community League executive. On June 2, 2015, the City provided a letter to the community league Executive outlining additional details about the timelines and process.
Soil Testing
Soil testing in Twin Brooks was originally planned for 2016, but was conducted earlier in response to feedback from the community league. The following summary of the soil testing report has been provided to the community league Executive.
A soils investigation report was undertaken on November 24, 2015 of the approved Twin Brooks First Place Program building site. The investigation was conducted by Hoggan Engineering & Testing (1980) Ltd.
Four test holes were drilled in the building site, two at depth of 7.3m (24 ft) and two at a depth of 4.2m (13.8 ft). During the drilling process, the soils were observed, recorded and sampled. Upon completion of the test holes, pipes were inserted into each hole to help determine water table levels. Water table readings were conducted at the end of the drilling, 4, 14 and 21 days later.
The groundwater table was not observed in the test holes at this site and therefore is considered low, at a depth greater than 6.9 meters below the existing ground surface. Surficial topsoil and organic clay materials were noted from 0.3m to 1.1m. This material is not suitable for footings or slab and should be removed and replaced with suitable material prior to construction.
There are no major problems anticipated with the construction of residential units on the native clay soils (below the surficial topsoil) as noted in the test holes. Subsurface soil conditions encountered in the test holes are considered satisfactory for installation of underground utilities.
