1. DEMOLITION ITEMS, DEBRIS, AND WASTE MUST BE REMOVED FROM AND

DISPOSED OF OFF NATIONAL FOREST SYSTEM LAND AND IN ACCORDANCE WITH

ALL FEDERAL, STATE, AND LOCAL WASTE DISPOSAL REGULATIONS AND POLICIES.

UNLESS OTHERWISE NOTED.

2. FILL ALL VOIDS CREATED FROM THE DEMOLITION WORK WITH UNSATISFACTORY

MATERIAL AND TOP WITH SOIL AND REVEGETATE UNLESS OTHERWISE NOTED.

3. IF DESTRUCTION AND/OR DAMAGE OCCURS TO ITEMS TO REMAIN OR TO BE

REINSTALLED, REPLACE THE AFFECTED ITEM(S) IN KIND AT NO EXPENSE TO THE

GOVERNMENT.

4. PROTECT EXISTING TREES AND OTHER VEGETATION UNLESS OTHERWISE

NOTED. NOTIFY CO IF EXISTING TREES AND VEGETATION CREATE

CONSTRUCTION CONFLICTS PRIOR TO DISTURBANCE OR REMOVAL.

5. PROTECT FISH LADDER FACILITY.

6. FLAG TREES FOR REMOVAL AND NOTIFY CO IN ADVANCE OF FELLING. ALL TREES

TO BE REMOVED MUST BE APPROVED BY CO

7. PREVENT EXCESSIVE ROCK REMOVAL DURING CONCRETE PEDESTAL REMOVAL

THAT MAY DESTABILIZE ADJACENT ROCK WHEN REMOVED.

DEMOLITION SUMMARY

REMOVE OBSERVATION STRUCTURE AND REINSTALL AT A LOCATION DETERMINED

BY C.0. APPROXIMATELY 300 FT NORTH OF THE TRAILHEAD ALONG ANAN CREEK

TRAIL NEAR THE LOCATION OF THE EXISTING ADMINISTRATION BUILDING. STAKE

OBSERVATION STRUCTURE CORNERS FOR CO APPROVAL. REPLACE ANY ROTTEN

OR DAMAGED MATERIAL DURING REINSTALLATION OF OBSERVATION STRUCTURE

WITH IN KIND MATERIALS, SEE SPECS. SEE SHEET 15 FOR DETAILS AND PLACEMENT

OF OBSERVATION STRUCTURE.

REMOVE TOILET STRUCTURE AND REINSTALL AT A LOCATION DETERMINED BY THE

CO APPROXIMATELY 300 FEET NORTH OF THE TRAILHEAD ALONG THE ANAN CREEK

TRAIL NEAR THE LOCATION OF THE EXISTING ADMINISTRATION BUILDING. STAKE

TOILET STRUCTURE CORNERS FOR CO APPROVAL. IF TRANSPORTATION OF FULLY

ASSEMBLED STRUCTURE IS NOT POSSIBLE, DISASSEMBLE AND REINSTALL . SEE

SHEETS 14 & 15 FOR DETAILS AND PLACEMENT OF TOILET STRUCTURE.

REMOVE LOWER DECK IN ITS ENTIRETY, INCLUDING BUT NOT LIMITED TO DECKING,

BEAMS, JOISTS, POSTS, GUARDRAIL SYSTEMS, CANOPY SYSTEM, AND FOOTING AND

FOUNDATION COMPONENTS THAT ARE NOT A COMPONENT OF THE FISH LADDER

FACILITY. CUT ALL EXISTING BOLTS, BRACKETS, OR OTHER ELEMENTS CAST INTO

CONCRETE WALL OR EXISTING CONCRETE WALL FLUSH WITH SURFACE. PROTECT

EXISTING FISH LADDER FACILITY.

REMOVE STAIRS CONNECTING UPPER AND LOWER DECKS IN THEIR ENTIRETY,

INCLUDING BUT NOT LIMITED TO DECKING, BEAMS, JOISTS, POSTS, GUARDRAIL

SYSTEMS, AND FOOTING AND FOUNDATION COMPONENTS. CUT ALL EXISTING

BOLTS, BRACKETS, OR OTHER ELEMENTS CAST INTO ROCK OR EXISTING CONCRETE

WALL FLUSH WITH SURFACE. REMOVE ALL CONCRETE FOOTINGS FROM UNDER

STEPS. IF CONCRETE FOOTINGS CANNOT BE FULLY REMOVED, TOP OF FOOTING TO

BE LEFT 6" BELOW SOFT SURFACES OR FLUSH WITH ROCK SURFACES. SEE SHEET

12, DETAIL 5 FOR INTENT.

REMOVE UPPER DECK IN ITS ENTIRETY INCLUDING BUT NOT LIMITED TO DECKING,

BEAMS, JOISTS, POSTS, FOOTING AND FOUNDATION COMPONENTS, AND GUARDRAIL

SYSTEMS. REMOVE ALL CONCRETE FOOTING AND FOUNDATION COMPONENTS

FROM UNDER PLATFORM. IF CONCRETE PILES CANNOT BE FULLY REMOVED, TOP OF

FOOTING TO BE LEFT 6" BELOW ADJACENT FINISHED SURFACE. SEE SHEET 12,

DETAIL 5 FOR INTENT.

EXCAVATE EXISTING TRAIL TO A DEPTH TO ALLOW RESTORATION. SEE SHEETS 11 &

12. CONTRACTOR MAY USE THIS MATERIAL FOR NEW TRAIL CONSTRUCTION IF

MATERIAL IS SUITABLE AND WITH CO APPROVAL.

NO EQUIPMENT OR DEMOLITION MATERIALS TO ENTER THE CREEK.

EXISTING TREE (36-48" DBH APPROX.) TO BE FELLED, LIMBED, DEBARKED, CUT ENDS

TO BE MASTICATED, AND LOCATED PER CO DIRECTION TO ACT AS HABITAT

ENHANCEMENT, SEE SPECIFICATION SECTION 31 10 00.

REMOVE LARGE TREE AND ROOT WAD AND DISPOSE OF ON-SITE AS DIRECTED BY

CO

SEE SHEET 11 FOR SOILS AND VEGETATION MAT REMOVAL FOR THIS AREA. MATS

AND SOILS TO BE REINSTALLED AS SHOWN ON SHEET 11.

ROCK REMOVAL MAY BE REQUIRED FOR INSTALLATION OF LOWER PORTION OF

SPIRAL STAIRS. FIELD VERIFY IF REQUIRED AND EXTENTS OF REMOVAL. OBTAIN CO

APPROVAL FOR EXTENTS, METHOD OF REMOVAL AND ANY STABILIZATION NEEDED.
