Memorandum

To: Rehabilitate the Tuolumne Meadows Campground Project Team

From: Keith Bates, Otak, Inc.

Copies: Project Team

Date: August 4, 2021

Subject: Construction Document Package Adjustments

Project No.: YOSE 229677

This memorandum is a general list of adjustments made to the Tuolumne Meadows Rehabilitation project bid documents since the project was initially advertised. This list may not include all items that may have been modified within the bid document package.

Many of the campsite adjustments were made to accommodate existing site conditions (primarily trees/boulders). In addition, after seeing the drainage patterns during the heavy storm, campsite amenity locations were adjusted within the proposed campsite areas. There were also a few campsites where the amenities were rearranged to preserve existing views of the surrounding natural environment.

LOOP A

Removed site A42 (existing A57) and reconfigured site A44 (existing A59) due to existing topography constraints and new Loop A alignment

Made A46 (existing A73) an accessible site Moved parking spur for A47 (existing A69) due to existing constraints and adjusted from ABA to standard site Removed A70 (new BP site next to existing A75) due to existing natural resource and added a new BP campsite between A58 and A61 (existing A84) Adjusted furnishing layout for existing sites A6, A10, A11, A13, A17, A19, A37, A41, A46, A55, A56, A58, A61, A62, A68, & A78 - Campsite area adjustments due to existing conditions.

• Note: Loop A campsites have been renumbered and therefore new campsite numbers have changed. Therefore, all new campsite numbers listed here may differ from the newly submitted plans but existing numbers remain the same.

LOOP H

Adjusted south walk-in sites due to existing conditions and to reduce potential tree removal Adjusted sites H1-H6 due to Loop H drive realignment
