Crane Flat Campground Septic Leach Fields Replacement
Yosemite National Park » Crane Flat Campground Septic Leach Fields Replacement » Document List
The project will replace all of the leach fields within the Crane Flat Campground. Actions include:
Comfort Station No. 1 (#6039) - Replace existing leach field with a pre-engineered leach field installed in the northwestern portion of the interior of the 200 loop, directly adjacent to the loop 200 campground road. Installation of this pre-engineered leach field would include the following activities:
Comfort Station No. 2 (#6040) - Replace existing leach field with a pre-engineered leach field installed in the southwestern portion of the interior of the 200 loop, directly adjacent to the loop 200 campground road. Installation of this pre-engineered leach field would include the following activities:
Comfort Station No. 3 (#6041) and Comfort Station No. 5 (#6043) - Replace existing leach fields with a single conventional leach field in the southern portion of the 500 loop. Installation of this conventional leach field would include the following activities:
Comfort Station No. 4 (#6042) - Replace existing leach field with a conventional leach field, located in the eastern portion of the area between the 400 and 500 loops. Installation of this conventional leach field would include the following activities:
The comfort stations are located in sites that pose a challenge to design a septic system that would allow for gravity flows. Because of these site constraints, the park is proposing to use a pre-engineered leach field system; an in-ground passive treatment that does not require pumping or aeration. This project includes the following approximate tree removal; 17 White firs (10 that are less than 8" diameter at breast height (dbh), five that are 16" - 24" dbh, one 48" dbh, and one 32" dbh) and two Western red cedars less than 20" dbh.
