About this file

Written by GovTribe AI · Dec 28, 2023

This document package includes construction drawings and specifications for the Alturas Water System Improvement & Cabin Creek Drainage Restoration project on the Sawtooth National Forest. Key details include construction of a new well, pump house, buried water and power lines to connect to the existing water storage tank. Additional work involves restoring the historic Cabin Creek drainage channel by removing fill material and abandoned roadways. Site improvements at the Alturas Lake Outlet Picnic Area include reconfiguring the parking lot, constructing a new trail loop and family campsites, and installing log fencing. The Forest Service will issue solicitation number 1240LT22R0008 prior to March 2022 for a contractor to perform the on-the-ground construction work starting in early-mid April 2022 after the water system shutdown, with completion anticipated by late summer 2022. A mandatory site visit for prospective contractors will be held on October 28, 2021 at the project location.

GENERAL NOTES:

1. THE PRIMARY OBJECTIVE OF THIS PROJECT IS TO RESTORE THE FORMER CABIN CREEK DRAINAGE CHANNEL TO ITS

HISTORIC LOCATION. THIS WILL PRIMARILY CONSIST OF 1) REMOVING EXISTING FILL MATERIAL FROM THE AREA

LIMITS NOTED IN A GRADUAL NATURE TO RESTORE THE TOPOGRAPHY TO ITS ORIGINAL STATE WHILE ALSO

ALLOWING DRAINAGE; AND 2) REMOVING THE UPSTREAM DIVERSION COLLECTION DITCH TO RESTORE FLOW BACK

TO THIS HISTORIC DRAINAGE. (THE UPSTREAM DIVERSION COLLECTION DITCH REMOVAL EFFORT WILL BE

PERFORMED BY OTHERS).

2. SUITABLE MATERIAL FROM FILL REMOVAL EFFORT WILL BE USED TO 1) BUILD UP AND RECONFIGURE THE OUTLET

PICNIC AREA PARKING LOT; 2) FILL IN THE EXISTING DITCH LOCATED ON THE NORTH SIDE OF FOREST ROAD #205;

AND 3) FILL IN THE EXCAVATION FROM THE FORMER RESTROOM VAULT LOCATED WITHIN THE ALTURAS OUTLET

PICNIC AREA. ANY EXCESS MATERIAL WILL BE HAULED/STOCKPILED WITHIN THE ALTURAS TENT CAMPGROUND

PARKING LOT AT THE LOCATION STAKED ON THE GROUND BY THE CONTRACTING OFFICER.
