One of the challenges of the City-selected site at the end of Darwin Avenue is that it has a very steep slope. That steep slope needed to be substantially re-graded. And re-grade they did this week!
Truckloads of dirt were dug out and removed from the site, and the remaining dirt was moved around the site to flatten it so more of the park's square footage is actually usable as a park.
Compare the two photos, below. They were taken approximately one week apart, and they show the extensive work that took place this week.
The overall site profile is mostly set now. At the top of the dog park, paint has been applied delineating, roughly, the stepped erosion-control features to mitigate the substantial runoff from the Takoma Park Middle School tennis courts (photo at left).
The school district has done nothing to mitigate the stormwater from their site, which has caused substantial erosion through the park prior to the dog-park work. The City is effectively mitigating the school district's stormwater problem for free to ensure that it does not damage the new dog park.
In addition to the stepped stormwater-control feature, there will also be a long drain that captures additional runoff from the school site. While the drain is not yet installed, it will be installed along the top of the dog park in the trench shown in the photo, right.
The drain, once installed, will collect runoff from the school district property and route it through a drain system under the dog park, shunting it into two "outfalls" just below the new dog park.
We have approximately 10 more weeks of construction. We'll keep you updated in the TakomaDogs Blog!
