About this file

This document is a detailed site plan and technical drawing for a septic system replacement project at CCC Cabin 321 located in Buxton, NC. The plan includes an aerial photo, existing septic system layout, and proposed septic system design for a National Park Service project. Key technical specifications include demolishing the existing 750-gallon septic tank, disconnecting the existing drain line, and installing a new 1000-gallon septic tank with a distribution box. The proposed system will feature two 30-foot trenches with infiltrator chambers, positioned 9 feet on center, and maintained with a minimum 5-foot separation from the slope's edge. Installation notes emphasize proper drainline slope, no horizontal pipe fitting connections, and careful excavation to avoid damaging existing utilities.

The design covers a total new disturbance area of 0 square feet within a 1,430 square foot location, with specific attention to preserving existing infrastructure like the HVAC heat pump and wood shed. The project is part of a federal solicitation (140P5325Q0014) for the National Park Service Cape Hatteras National Seashore, set as a 100% small business procurement with an estimated value between $25,000-$50,000. The period of performance is scheduled from 5/1/2025 to 7/31/2025, with a site visit planned for March 28, 2025, and quotes due by April 10, 2025 at 1 PM EST.

DEMOLITION NOTES:

1. PRIOR TO DIGGING, LOCATE EXISTING

UTILITIES IN THE PROJECT AREA.

2. DIG UP AND TURN SOIL IN THE NEW

DRAINFIELD AREAS, REMOVING ALL ROOTS

OR UNSUITABLE SOIL.

3. CAREFULLY EXCAVATE SOIL OR HAND DIG

TO AVOID DAMAGE TO THE EXISTING

ELECTRIC, WATER, SEPTIC, AND

COMMUNICATIONS LINES.

4. DO NOT TRAVERSE OVER UTILITY LINES

WITH HEAVY MACHINERY OR OTHER

VEHICLES WHICH WOULD DAMAGE

EXISTING UTILITY LINES WITHOUT

SPREADER PLATES.

INSTALLATION NOTES:

1. INSTALL NEW SEPTIC DRAINLINES WITH POSITIVE SLOPE

(MINIMUM 18 INCH PER FOOT) TO THE TANK, DISTRIBUTION BOX,

AND DRAINFIELD TRENCHES. DO NOT INSTALL DRAINLINES AT 0

PERCENT OR UPHILL SLOPE. SET TANK, DISTRIBUTION BOX, AND

TRENCHES AT ELEVATION TO ENSURE DOWNHILL SLOPE OF ALL

DRAINLINES.

2. SANITARY TEE CONNECTIONS SHALL NOT BE PERMITTED FOR

HORIZONTAL TO HORIZONTAL PIPE FITTING CONNECTIONS.

3. BACKFILL, RAKE SMOOTH, AND GRADE RUTS, EXCAVATIONS,

AND DISTURBANCE PRIOR TO SEEDING.
