The rising cost of environmental work related to the San Diego water transfer will have the Imperial Irrigation District Board of Directors voting at its meeting Tuesday whether to amend its environmental consultant's contract to include those costs.
The rising environmental assessment and requirement costs result from the evolution of the Colorado River Quantification Settlement Agreement and the clarification of related subagreements, according to agenda materials.
IID staff is asking the board to amend its contract with environmental consultant CH2M Hill from its current amount of $5.2 million to $6 million.
IID has budgeted and secured bond financing for $23 million to cover water transfer expenditures. All costs associated with the transfer are 35 percent reimbursable by the San Diego County Water Authority.
