RECOMMENDATIONS
1.Award a contract to Charles Abbott and Associates,Inc.in the amount of
$50,000,to perform a GPS survey of all existing points within the Portuguese
Bend /Abalone Cove Landslide area and to prepare the associated report.
2.Authorize the expenditure of $50,000 for the required survey and associated
report;and authorize the expenditure of up to $4,500 (8.3%)as a project
contingency in the event additional work is identified during the field survey and
is determined to be required by the Director of Public Works.
BACKGROUND
For many years the City has collected land movement data in the Portuguese Bend
Landslide area.Following the public meeting in October 2007,the City Council
requested that Staff work with consultants to develop a precision method of collecting
land movement data.Using new technology,best efforts were made over the past few
years to use the latest methods in measurement and to portray the information.To
accomplish an efficient use of resources,a thorough and detailed scope of work was
established.Staff coordinated this effort with the City Geologist and Charles Abbott
Associates,both of whom have extensive knowledge about the landslide area.
The outcome was a carefully defined scope of work using techniques that have proven
to collect the needed data with an efficient and effective use of resources.
ANALYSIS
4-1
In order to better quantify the land movement,best practice survey methodology is used
to measure existing monuments and established points with Global Positioning System
(GPS)satellite survey methods.Charles Abbott Associates (CM)and the City's
Geologist have been instrumental in establishing the method that is currently used to
collect and record data.The most recent data is compared to the data previously
collected by CM which reveals any differential land movement.The scope of work for
this years'GPS ground movement monitoring project is consistent with last year.As
previously stated,the information gathered is used to compare movement from year to
year.The methods and techniques being used have been discussed with the City
Engineer and the City Geologist to better focus measurement methodologies and
optimize the level of service while minimizing the program cost.To that end,and for the
importance of continuity,Staff is recommending awarding this year's contract for GPS
survey work in the landslide to CM.Staff is anticipating beginning the survey in late
October early November to obtain results prior to the onset of the rainy season.
CONCLUSION
It is important for the City to properly monitor land movement in the Portuguese Bend
and Abalone Cove areas.We therefore recommend award of this contract to the
Consulting City Engineer,Charles Abbott Associates.
Adopting the staff recommendation will award a contract to Charles Abbott Associates
in the amount of $50,000 to perform a GPS survey of existing monuments/survey points
and associated work and authorize the expenditure of up to an additional $4,500 for
additional work that may be necessary.
FISCAL IMPACT
The recommended action,which includes a complete survey of all existing monuments
and points,processing and interpreting the data,and creating the associated report,will
be completed for the lump sum cost of $50,000.Additional work if necessary could be
accomplished with available funds up to an additional $4,500.
The required funds are currently budgeted in the FY 10-11 Improvement Authority's
program for this project.This budget is allocated between the Portuguese Bend
maintenance services and Abalone Cove maintenance services.
