2022 Geotechnical Hazard Abatement District (GHAD) Maintenance Services

The City of Pleasanton is seeking bids for geologic hazard abatement district (GHAD) maintenance services at the City's four GHAD districts. In general, the services include (but may not be limited to) the following work in undeveloped open space areas with limited equipment or vehicle access: . Removal of weeds, leaves, soil, moss, and debris within and adjacent to concrete-lined drainage ditches; . Trimming and removal of woody vegetation to clear drainage swales and provide downward flow without ponding; . Correction of surficial erosion or landslide scars on graded slopes including placement of soil, installation of fiber rolls, and/or installation of erosion control blanket on exposed soil; . Applying rodenticide, filling/regrading of rodent burrows that obstruct storm flow patterns; . Cleaning/clearing of stormwater inlets and openings that serve hillside ditch networks; . Minor repairs to concrete structures such as ditches, storm inlets, or retaining walls where non-structural cracking or displacement has occurred; and . Removal and legal disposal of trash and debris. There are four GHADs within the City of Pleasanton, all located on the west side of Foothill Road (See Vicinity Map included as Exhibit A) . The four GHADs provide services to a combined total of 275 parcels as follows: . Laurel Creek GHAD (121 parcels), . Moller Ranch GHAD (100 parcels), . Lemoine Ranch GHAD (12 parcels), and . Oak Tree Farm GHAD (42 parcels) A GHAD is a property assessment district that is formed to fund annual geologic and storm drainage infrastructure monitoring, to perform annual maintenance and to repair slope stabilization infrastructure, significant landslides or other geologic movement, should it occur within the District. Each District is defined by a geographic boundary . The source of funding for GHADs is an annual tax assessment from each property within the District. GHADs are authorized by California Public Resources Code 26500. The four GHADs were established prior to the approval of Proposition 218 in 1996. The funding is therefore limited to the amounts collected as tax assessments each year. The Engineer's cost estimate for performing the described work is as follows: Estimated Lump Sum Cost: Laurel Creek $30,000.00, Moller Ranch $25,000.00, Lemoine Ranch $8,000.00, Oak Tree Farm $7,000.00; Total Estimate $70,000.00.
