These tasks assume adequate monumeniation exists on or near the property to make an
accurate boundary determination. if adequate monumentation does not exist, additional
research and field work may be necessary. VHB will contact the City prior to HSI performing any
additional work to discuss the costs associated with any additional work and a mutually agreed

Note that in order to perform their work, HSI staff may need to access abutting properties.
Although HSI will make every effort to locate the potential encroachments and boundary
monuments without trespassing on abutting properties, it is advised that the City obtain verbal
or written permission for temporary access oy the field crews. If physical access is necessary, but
denied by the abutters, then the City may want to seek legal advice on how to proceed.
