This report presents a summary of the GHAD eipenditures during the first quarter of
Fiscal Year 2003/2004. A summary of the expenses and the budget balance is
presented below in Table 1.

In order'to compare the quarterly expenses with the previous fiscal year the data has
been plotted on the bar chart below based on expenditures in each category. The
' comparison shows that the major project expens s are significantly less in FY 03/04
'_,because.' the FY 02/03 major projects included the carry over from the
Sequoia/Conifer landslide repair. Preventive in intenance is slightly greater due to
i the follow through on the winter storm damage. `Special Projects are less, but this is
due mostly to the timing of the Special Projects c xpenditures rather than a significant
budget difference. Administration expenses dropped significantly because the
General Manager position was in transition in the previous year. A description of the
activities in each category follows.

A cost sharing agreement for the cleanup
' was qegotiated with the Blackhawk
x` Homeowners Association and the Country
Club. 'A diver and suction dredging
equipment was required in conjunction with
conven onal de-silting equipment to free the
pumping facility and restore the detention
basin.
s
Extensive consultations were required with
the GH D's wetland consultant, Sycamore
Associates, to satisfypermitting requirements. 'he dredging operation was complete
and the pumping facility and water feature resto Sed in September.
9231929 Lade Rid; a Landslide Repair #
The Eagle Ridge Landslide Repair was the larg4st major project undertaken in 2003.
The slope failure developed during the El Ninq rains of 1998. A shallow landslide
occurred on the common area slope behind 92 and 929 Eagle Ridge. Subsequently,
a consultant was retained to observe the slope failure and make preliminary
recommendations for a repair scheme. The consultant observed that the slope failure
involved the upper area of the slope behind 923 and 929 Eagle Ridge. The unstable
area measured approximately 250 feet wide by 75 feet.
A repair scheme was recommended that included excavating and rebuilding the slope
with gea-synthetics reinforced fill and a subdrair age system. Plans and specifications
were generated;however,the repair contract was deferred through subsequent years.
During the winter of 200212003 the slope mov'ment had extended father onto the
homeowners rear yard area creating a heightened sense of concern with the upslope
homeowners.
{f
9 4
i
The slope repair project was included in the FY�' 00312004 budget with an estimated
cost of repairs of$250,000.00. Continued deterioration of the slope and a developing
condition threatened to cause additional damage w property improvements in the rear
yards of'adjacent properties. The General Manag r declared the project an emergency
condition requiring mitigation measures prior to the upcoming rainy season. Efforts
were undertaken to expedite contract documen and secure a qualified contractor.
1 The project was presented to the Board and consuvction was anticipated to start early
{ in the second quarter.

59 Chestnut Landslide Repair and Tlrainage I irovement
gg ` During the December 2002 rain event, a shallow
slope failure, occurred on the slope below 59
t Chestnut. Thi primary cause of the failure was the
concentration)of runoff from the approximately 100
foot high slops above the west side of the property
overflowing and undermining a concrete lined
ditch located along the base of the slope. Repair
# u schemes wew evaluated to provide a two-phase
project that would repair the slope below the
property and increase the capacity of the conrete lined ditch above the property.
Cost estimates were obtained and construction scheduled for completion prior to the
rainy season. {
3130 Blackhawk Meadow Landslide Repair
For several years continued erosion has oecur�£'red on the slopes of Alamo Creek
s bisecting the property of 3130 Blackhawk Meadow. The progressive nature of this
erosion,,in one location, has created a 60 foot high near-vertical slope that threatens
r�Fi w the driveway end only access to the property.
DurinpL`s the first quarter, the site was investigated,
� `�}i
! ' and a slope ptabilization option was developed
° i consisting of the installation of a row of closely
} M r spaced drilled'i shafts located along the top edge of
the potential slide area. The District Manager
3a 2t
negotiated a 50-50 cost sharing agreement with the
property own
I

Work was completed on the annual cleaning o the B-58 drain systems, work was
CO
mpleterd on the 120 Deer Ridge Place Debis Wall, as well as several minor
