SANTA ANA CLIMATE ACTION PLAN INITIAL STUDY CITY OF SANTA ANA table level (e.g. the production rate of pre- existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? No Impact. The Draft CAP proposes measures that would not deplete groundwater or interfere with groundwater recharge. The proposed Draft CAP intends to promote water conservation through incentivizing the use of rain harvesting barrels, California friendly landscape (i.e. drought tolerant), and turf removal. Improvements to pedestrian, bicycle, and transit connectivity could increase the amount of landscaping which could increase the need for water for irrigation purposes. However, any landscaping would not be substantially deplete groundwater supplies or interfere substantially with groundwater recharge and would comply with applicable water- efficient landscape standards within the City of Santa Ana Municipal Code. 37 No impacts to groundwater supply would occur. c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the coarse of a stream or river, in a manner which would result in a substantial erosion or siltation on- or off -site. Less than Significant Impact. The Draft CAP proposes measures, such as improving the bike and pedestrian network, that could alter existing drainage patterns. However, these projects would largely occur within existing rights -of -way where drainage patterns already exist and would also not result in substantial erosion or siltation on- or off-site. In addition, a majority of the proposed measures involve replacing and retrofitting existing structures and streetlights, which would not alter existing drainage patterns. Therefore, improvements and development consistent with the Draft CAP would not substantially alter existing drainage patterns. The impact would be less than significant. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off -site? Less than Significant Impact. The Draft CAP proposes measures that would not directly alter existing drainage patterns. However, some measures, such as improving the bike and pedestrian network and implementing the Safe Routes to School Program, could slightly increase the amount of surface runoff due to new pedestrian and bicycle paths. However, the addition of new pedestrian and bicycle paths would not result in substantial surface runoff increases and any changes would be subject to existing federal and state regulations, The impact would be less than significant. e) Create or contribute runoff water which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff? Less than Significant Impact. As stated above, the City of Santa Ana is largely built out and contains areas where stormwater drainage systems already exist. Implementation of the Draft CAP would enhance pedestrian, bicycle, and transit connectivity, implement the Safe Routes to School Program, and encourage the development residential nodes near retail and employment nodes. However, both construction and operation of future development would be subject to CEQA review and would be required to comply with applicable regulations from the City and NPDF.S in relation to stormwater pollution prevention.
