HomeMy WebLinkAboutLot Certifications - 09/15/2022629 Smith Street New Garage Drainage Certification – Permit # B2008317
History:
A new detached garage at 629 Smith Street was permitted and is now in the final stages
of being completed. Unfortunately, the original permit and design were done a few
years ago and the permit was renewed multiple times. During the time between
original design and construction, some additional / new landscaping was completed
immediately west (behind) of the existing home. This landscaping contemplated the
new garage and the drainage requirements and incorporated an 8” drainpipe to move
water from the back of the lot to the front of the lot per the permit and design
requirements.
System Design:
The system has three parts to its design, which are annotated on the approved site plan.
Pictures are attached showing the interfaces.
A: The gutters on the garage have been installed to drain away from the alley (towards
the East) and the flow from these gutters is captured in drain boxes that flow into
separate 4” underground drainpipes. Those pipes run away from the garage (towards
the East) and into the 8” drainpipe that was previously installed during the initial phase
of the landscaping.

B: During the initial phase of landscaping, an 8” drainpipe was installed along the north
side of the house to accommodate the future garage and drainage requirements.
C: The final phase of landscaping is now being completed and 20’ of perforated 8”
drainpipe has been installed at the front (East Side) of the residence, which is buried
into the ground and backfilled with gravel. The entire front of the house has is being
landscaped with rock, low water plants and boulders. An additional section of 4”
drainpipe has been added to the end of the drain section with a pop-up outlet that will
terminate in a ‘dry river’ that will be part of the landscaping.
