You may have noticed the orange barrels, barricades, and yellow caution tape this last few days at the dog park. The large storms that rolled through on Thursday caused the slope to be undermined. According to Daryl Braithwaite, the City's Public Works Director, "today's rains created a below surface erosion issue under the artificial turf."
Apparently the large stormwater structure that sits at the top of the park that controls runoff from the school grounds and tennis courts, "was not working well enough and water was being driven under the surface and as a result moved some of the stone base beneath the artificial turf," Daryl said.
The City's contractor was onsite Friday to begin remedying the problem.
It is unknown whether this problem resulted from a design flaw or faulty construction. If the former, the City would be responsible for the additional cost to remedy the problem; if the latter, the responsibility would be the contractor's.
TakomaDogs raised concerns about the possibility of the turf underlayment shifting over time as it appears to have had some minor shifting already. City staff assures us, however, that the issue the park experienced is not a stabilization problem of the subsurface materials, but is instead "related to uncontrolled water escaping [the] storm structure and migrating under [the turf]."
Daryl expects that the stormwater repair work will be done over the next week or so, but that she's not sure yet when the sub surface erosion will be corrected. Given that "there are voids beneath the artificial turf," the City recommends staying out of the area that's marked off because City staff want to make sure no one steps through the turf, loses their footing, or twists an ankle.
