The Municipality of Anchorage Development Services Department (DSD) issues Certificates of On -Site Systems
Approval (COSA) based only upon the representations given in paragraph 4 by an independent professional civil

title (except between spouses) for properties served by a single-family on-site wastewater disposal and/or water
supply system. DSD also Issues COSAs upon request to homeowners. Certificates of On -Site Systems Approval
are valid for 90 days from the date of Issue for properties served by a private or Class C well and may be reissued
with new water sample results. (Certificates may be reissued for a period of up to one year with valid water
samples.) Certificates are valid for one year for properties served by Class A or B wells or a public water system.
The Municipality of Anchorage is not responsible for errors or omissions in the professional engineer's work.

Subject: WAVIER REQUEST
TI 2N R3W S23 NE4NW4SE4 & NW4NW4NE4SE4
11657 Rock Ridge Drive
Ladies and Gentlemen:
With this submittal we are applying for a waiver of the 100 foot separation distance required
between a septic tank and drain field and surface water. During the well & septic inspection
conducted in order to obtain a Certificate of On-site System Approval a small pond (surface area
of approximately 200 ft2) was observed approximately 85 feet north of the existing septic tank
and drain field.
The existing onsite wastewater system consists of a 1250 gallon concrete tank, a deep trench and
concrete crib absorption field installed on July 28ih, 1975. The tanks appear to be in good
condition and the drain field passed an adequacy test on April 20, 2010.
The drive way provides a highly visible barrier between the septic system and the pond. If the
septic system were to over flow it, sewage from the system would flow down the drive way. This
area is heavily trafficked and it is unlikely that surfacing sewage would go un- noticed. The pond
is impounded by the driveway and completely on private property limiting the possibility of a
public health hazard. It is my opinion that granting a waiver surface water separation of 85 feet
will not negatively impact public safety.
Waiver Request: 85 feet from surface water to existing septic system.
The septic tank and drain field are underneath the southern edge of the driveway. This is out of
the direct travel paths and parking areas of the driveway. The septic system has been operating in
the configuration for over 20 years with no discemable negative impacts. Four inches of

insulation was installed over the drain field to prevent freezing. It is my opinion that the system
will continue to function adequately in this configuration.
The septic tank is likely less than 5 feet from the garage foundation. The septic tank is
constructed of concrete and the garage has a slab foundation. The septic system has been
operating in the configuration for over 20 years with no discernable negative impacts. Please grant
a waiver of the required 5 foot separation distance.
Waiver request: 4 feet from edge of septic tank to garage foundation.
If you have any questions or are in need of additional information please contact me at 279-3916.

Your request for multiple waivers is approved as noted below:
• 4 foot septic tank to building foundation,
85 foot septic tank to surface water,

Ladies and Gentlemen:
During the COSA inspection the septic system several irregularities where noted at the above referenced
property. The installation permit states that the septic system will be sized for a two bed room residence. The
soils were rated at 180 sq.fl. per bedroom. The current house is three bedrooms. A 1000 gallon tank 540
square feet of absorption arca is required. The existing system consists of a 1250 gallon concrete tank, a 42
foot long absorption trench with a 6 foot effective depth and a 6 foot diameter crib. The tank is sufficiently
sized for 3+ bedroom. The absorption area of the trench is 504 sq. ft. and the absorption area of the crib is
113 sq. ft. (Table 7-6, Design Manual Onsitc Wastewater Treatment and Disposal Systems, EPA) for a total
of 617 sq. ft.
A barricade has been installed over the septic tank and a berm has been built along the south edge of the
driveway to ensure that any septic tank overflow would have to travel more than 100 feet before reaching
surface waters.
If you have any questions or concerns, please contact me at 279-3916.
