Dear Si r:
Subject: .~LQ$ 8, ~]9ck 5, Spring Brook Vista, EaGle R!ver~_~laska
We t]ave reviewed tile plans and specifications for the subject project.
The plans are approved, conditioned on adherence to the following items:
1. screened rock back fill in deep and wide trenches (3/4" - 3").
2. screened rock'back fill in absorption bed (3/4" - 1~t/2").
3. sufficient area plotted on as-built for replacement system.
This letter constitutes the pemit required by A.S. 46.03.720(a) for
plan approval of sewera9e systems.
It should be remembered that final approval will necessitate the submission
of Engineer As-built Plans to include photographs as indicated on page 13
of enclosure. This will consequently mandate that a professional engineer
conduct basic inspection of this project so as to be able to sign off on
as-built plans. Arrangement for this inspection work is the responsibility
of the developer.
