Mitigation

Mitigation 1. Allowable costs include the costs of: A. Mitigation of only direct adverse physical impacts resulting from construction of the project. B. Reasonable site screening necessary to comply with required environmental review and necessary to screen adjacent properties. C. Groundwater monitoring facilities necessary to determine the possibility of groundwater deterioration, depletion or modification resulting from construction of the project. The extent of the allowable costs for groundwater monitoring facilities is decided on a case-by-case basis and depends on the size and complexity of the project and the present and potential future use of the groundwater. 2. Unallowable costs include the costs of: A. Solutions to aesthetic problems, including design details which require expensive building techniques and architectural features and hardware, that are unreasonable or substantially higher in cost than approvable alternatives and that neither enhance the function or appearance of the treatment works nor reflect regional architectural tradition. B. Land acquired for the mitigation of adverse environmental effects identified pursuant to an environmental review.
