SAN RAMON CANYON -25TH STREET PROPERTY OWNER
Gordon,
At the June 17th meeting at RPV City Hall,you volunteered to contact the owner of
the property in the San Ramon Canyon immediately above 25th Street to open the
lines of communications.RPV agreed to extend Harris and Associates'design
contract to include the creation of an exhibit that could be used to show the extent
of the required easement.This design has been produced and is attached.
The obtaining of an easement that would allow one or more of the following:
•The opening of the existing inlet structure,located 15 to 20 feet below the
existing grade
•It may allow for a much improved design for the interim measure that CLA is
currently proposing
•It could allow for the construction of a sufficiently large debris basin to contain
the debris flow from a large storm event and so reduce the possibility of
flooding 25th Street
•It will allow for future construction access for the "final solution"
•It will provide the basis to do obtain an environmental clearance for any/all of
the above
•It will provide the flexibility to make decisions irrespective of constrains
imposed by schedu Ie
At the meeting,the idea of approaching the land owner was welcomed by both RPV
and the County.The City representatives had some reservations,however we
believe that it will a time consuming process and the sooner we start the process,
the better.
Please let me know if there is anything more that you require from us to make the
first contact and start the process.Call me if you have any questions.
