Remediation Design Alternatives

To the right, you will notice that the site is mostly flat with some large mounds in the northern portion, and the southern portion is a sharp steep slope.  The area surrounding the Boneyard is a gradual slope, starting at the northern end, that continues to the bottom of steep incline at the southern end.


Two remediation designs have been developed.  Both alternatives include the removal of fill from the Boneyard, and both attempt to match the surrounding grades.  The major difference in the designs is the cost, and quantity, of fill removal.  The fill will be removed, then transported via dump truck to a local landfill.

Once final grading is completed, flora, native to the area, will be planted.  The goal is to make the Boneyard look like it was never there.

The alternatives stated above require little maintenance.  Having an NPS official stop by on a bimonthly basis through the first rain season, followed with a semiannual check for the following 2 years will suffice.  Should a problem be found during one of these inspections, appropriate actions will be taken.


Alternative 1 consists of removing all of the fill material on the site.  This plan will require approximately 350 cubic yards of fill to be removed.  This is the best alternative for matching the surrounding area and “turning back the clock.”  This is also the most expensive alternative due to the amount of fill that needs to be removed. Alternative 2 consists of removing the majority of the fill material on the site.  The site will be graded to match the surrounding area except for the south-eastern section.  That portion will remain at a slightly higher elevation than alternative 1.
