From time to time some of our drives need an application of gravel (or DG or aggregate base) to prevent erosion. There is, however, a need to be sure that we don't import any non-native plant seeds along with it. Neither the NPS nor we want to introduce any problem plants (weeds, etc.) into the park.
Accordingly, if you need to bring up a load of gravel, once you have located a source – but before you purchase the material – please advise the vendor that the NPS will be by to inspect the material and certify that it is seed free.
Then please give Christine Smith a call at 559-565-3105. If the Park Service is not already familiar with the vendor, it will dispatch someone to inspect the material. Christinehas promised that the process will be completed within ten days.
