LAND SURVEYING
To: Garfield County Building Division of the Community Development Department
Matt Provost, Inspector
From: Roger Neal, P.E.
Date: February 19, 2018
Project: 2151036.00 — Cotton Hollow, Carbondale
Subject: OWTS Construction Approval Letter Permit BLRE004-17-4671
The proposed OWTS field design for 200 Cotton Hollow Lane Carbondale, CO has been installed per the
approved and permitted plans (Permit Number BLRE004-17-4671). The installation contractor was the
owner.
The bed was constructed per plan with 60 - ARC 36 chambers, a 1000 gallon polyethylene tank, distribution
box and associated piping and cleanouts. The chambers were placed with between 1'-3' of cover from
existing or proposed grade. Insulation was used above the pipe from the septic tank to the distribution box
to accommodate shallow cover concerns. Cleanouts and Inspection ports were placed according to plan.
The field is located in their general area of design as shown on the following page. The distribution pipes
were placed per plan and can be seen in the attached pictures. The inspection ports that were installed were
brought well above grade as shown by photos.
Attached are photos of the installation.
Please let me know if you have questions pertaining to this acceptance letter submittal.
Thank you,
