The slow creep may cause a pistol-butting of tree trunks during their <br />early growth phase until substantial root mass and trunk strength is developed. Creep is common on most <br />hillsides and does not indicate gross landslide movement. Creep movement is generally mitigated by modern <br />foundation systems and control of soil moisture and temperature under and around the residence to where <br />the slow movement is unnoticeable over the typical lifespan of a residence. <br /> <br />Sincerely, <br />Branch Engineering Inc., <br /> <br /> <br />Ronald J.
