Regional Water Quality Control Board Order R9-2007-0001 Provision D.1.g (6) (Board Order) requires the County of San Diego and its NPDES Co-permittees to identify Interim Hydromodification Criteria (IHC) within 365 days of Order adoption (i.e., by January 24, 2008). The interim criteria will apply until the final Hydrograph Modification Management Plan (HMP) is implemented. The IHC is described in the order as “an interim range of runoff flow rates for which Priority Development Project post-project runoff flow rates and durations shall not exceed pre-project runoff flow rates and durations.” The purpose of the IHC is to prevent development-related changes in stormwater runoff from causing, or further accelerating, stream channel erosion or other adverse impacts to beneficial stream uses. This memorandum provides background on fluvial geomorphology and hydrograph modification management, describes flow control criteria applied in other HMPs, and provides a recommendation for developing the San Diego IHC.

 Request for Data: Southern California Bight Marine Environment

The Marine Conservation Research Institute (MCRI), part of the Aquarium of the Pacific, is conducting a survey to identify all individuals or groups doing long-term observing of marine ecosystems, their characteristics or inhabitants, as well as other environmental processes or activities that directly relate to the marine environment. Types of data could include oceanographic data, coastal environmental data or watershed data. We are interested in identifying anyone with such data relating to any aspect of the marine environment in the Southern California Bight, defined as the area between San Diego and Pt. Conception. 

Please help identify individuals or groups who have data relating to, or impacting, the marine environment in the Southern California Bight.

If you have any questions, please feel free to contact Tom Turney at turney@newcap.com or at 310-645-7900 x22.
