I have been meaning to get out here for a while to see the progress on this project in Glendale. The last hurdle from the grading plans was installing the drywell.
The most interesting design element of this this site is that phase 1 and phase 2 are a few inches apart and do not touch. Also the lowest parking level can only be entered from the other street. This picture shows the temporary construction driveway that looks close enough to the excavation plans. So phase 2 underground parking can only be driven into from phase 1. Very confusing, but an interesting way to build these projects out.
A better view of how phase 1 looks in relation to the hole for phase 2.
Another view of the connection between the underground parking. Also the drywell is shown near the middle of the picture. The drywell is 6' diameter encased in concrete and goes down more than 40' below grade. Not to mention this was poured slightly off from the original location, as that drill is forever stuck in the ground and now encased. This drywell is also at the limits of the garage walls, infiltration setbacks, and sidewalk. When the overflow pipes are more obvious I will take some pictures of how this overflows. The entire site drains the stormwater into this drywell. The design was as complicated as it sounds. Subdrains go to a sump pump, a couple of catch basins go to this same sump, and the downspouts gravity flow all into the drywell. The pipe network was shown on our grading plans and was something else to convey the information needed for the grading plan check. Pipe inverts all over the place of the interior of the building. And don't forget we needed to prove that if anything ever backed up that the building is not getting the backup, the water will go to the overflow. Many weeks of back and forth at the City lead me to just about getting an office there.
The workers joked about this site finishing before the site to the right. That one has been in construction for three years. Our site has been in construction for about 8 months.
Another view of phase 1. The final look should tie in nicely with the surroundings along Central Ave.
The sideyard was going to get a massive raised planter box, but the drywell now takes care of that. The sideyard will instead get landscaping and a concrete walk.
Before the crosswalk ramp gets changed.
Across the street shows what the eventual crosswalk ramps will look like. Notice at the back of the sidewalk there is a straight line. That is the dedication or easement that these projects all around Glendale are giving up.
