Re: New Septic Permit and slope waiver
Legal: SOUTH LAKE WOOD HILLS BLK 1 LT 6
To Whom it may concern:
This is a request for a septic permit on the above referenced lot. A single test hole
was excavated and found silty gravels GM for the entire depth and no water
observed during the excavation or after the 7 day monitoring period. However
during spring runoff in 2017 water was measured at 15 feet in the test hole. The
creek to the south side has been shown on the site plan and a 100 foot offset.
The application rate is 0.8 GPD/SF for a 4 bedroom system which translates into a 7
foot effective by 54 feet long. The secondary site will be the Advantex system. We
are also requesting a slope waiver on the south end of the leach field, see attached
profile. It's not an issue but we are within 50' of a slope greater than 25 percent
therefore its necessary.
This new system will not impact any of the neighboring lot and will meet all of the
local Municipality of Anchorage On-site requirements.
Please call me if you have any questions.
