2.1.1 Narrative
As of 9/20/12, the ERRS contractor had completed reconstruction of a majority of the repository retaining wall and construction of a 20' x 20' x 25' deep dry well in the center of the repository to handle stormwater runoff.
2.1.2 Response Actions to Date
The damaged portion of the 19' high retaining wall has been re-built in a stable configuration. Presently, ERRS is rebuilding the previously un-damaged south wing portion of the retaining wall, as it is necessary to bump the wall out so that the repository can handle additional volume resulting from installation of the large dry well. Installed toe drainage to dry well outside of the wall, and installed a large dry well and drainage area in the center of the repository, that is designed to handle surface water runoff from the Church parking area and from the geosynthetic liner that will be placed over the top of the repository, to mitigate any future surface water infiltration and saturation of soils behind the retaining wall.
