Environmental Checklist Hydrology and Water Quality Final Initial Study – Negative Declaration 59 10 Hydrology and Water Quality Potentially Significant Impact Less than Significant with Mitigation Incorporated Less than Significant Impact No Impact Would the project: a. Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality? □ □ ■ □ b. Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? □ □ □ ■ c. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: □ □ □ ■ (i) Result in substantial erosion or siltation on- or off-site; □ □ □ ■ (ii) Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site; □ □ □ ■ (iii) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or □ □ □ ■ (iv) Impede or redirect flood flows? □ □ □ ■ d. In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? □ □ ■ □ e. Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? □ □ □ ■
