Nathan Schaedler, PE
<br />Southern California Coastal Water Research Program (SC(:NX'RP) Wet Weather Monitoring Program (Multiple Task
<br />Orders) San Diego, Orange, Ventura, Riverside and Los Angeles Counties, CA
<br />Project manager for more than $600,000 in task orders. Projects included various monitoring programs to support
<br />water quality models used to assess and develop TMDLs, storm water flow monitoring and sample data collection to
<br />model contributions of pathogens, nutrients, and trace metals over a 48-hour storm to support the Bacterial TMDL
<br />for Ballona Creek, and monitoring of dry and wet weather flows from seven mass emission sites, and 24 mixed land
<br />use watershed sites in support of TMDL assessments for bacteria, nutrients, pesticides, and trace metals in the Santa
<br />Monica Bay, Los Angeles River, Ballona Creels, Dominguez Channel and San Gabriel River watersheds.
<br />San Diego County Regional Airport Authority (SDCR1.1) BMP Program, hydrologic and Stormwater Services, San
<br />Diego International. Airport, CA
<br />Oversees the development of a BMP program for the San Diego International Airport to meet the requirements of
<br />SDRWCB Municipal Permit Order 2001-01. The project includes performing a hydrology and hydraulic assessment
<br />of the drainage system, evaluating existing storm water conveyance system and treatment facilities, performing a tidal
<br />surge study to mitigate contaminated sediments, evaluating potential pollutant sources, evaluating compliance with
<br />existing state, federal, and local storm water and environmental regulations, developing recommendations for BMPs
<br />for existing facilities and planned expansions, and preparing a Storm Water Master Plan, Capital Improvement Plan
<br />(CIP), and GIS application.
<br />Storm Wates Management Plan and B%1P Program, UCSD/Scripps Institution of Oceanography, San Diego, CA
<br />Managed the development of a Storm Water Management Plan and BMP Program for UCSD and Scripps in
<br />conjunction with state and federal regulatory and environmental stakeholders such as the San Diego RWQCB, City
<br />of San Diego, and Baykeeper. The project implements many of the conditions issued in Scripps NPDES Permit for
<br />discharging into the adjacent Marine Life Refuge, an ASBS. The project included: (1) developing the UCSD Storm
<br />Water Management Plan for the more than 1,000 -acre campus and the Scripps portion of the La Jolla Coastal
<br />Watershed Management Plan; (2) conducting a hydrology assessment of the watersheds; (3) determining the capacity
<br />of the Scripps Watershed drainage system, (4) selecting and prioritizing various structural and non-structural BMPs
<br />for implementation throughout the campus; (5) preparing preliminary designs and cost estimates for high priority
<br />structural BMPs; (6) developing a CIP to implement these BMPs; (7) helping prepare various grant proposals;
<br />(8) developing conceptual designs of options to divest dry weather flows to protect the California coastline.
<br />Caltrans Technical and Professional Storm Water Quality Monitoring and Reporting Services (Contract 43A0208),
<br />Caltrans Districts l., 2, and 4, CA
<br />Project manager for the implementation of 16 task orders totaling more than $4 million. These task orders have
<br />included developing and implementing Water Pollution Control Plans, evaluating the water quality performance of
<br />open graded/gap graded pavement, monitoring discharges into ASBS, performing long-term characterization
<br />studies, evaluating the performance of vegetated embankments alongside roadways, conducting studies and
<br />preparing plans to comply with the mercury and nutrient TMDLs within the Cache Creek and Clear lake watersheds,
<br />and monitoring the performance of bioretention cells constructed to treat runoff from the San Francisco -Oakland
<br />Bay Bridge,
<br />Caltrans Storm Water Monitoring Services (Contract 43,\0035), Statcw(de, CA
<br />Project manager for more than $10 million in storm water -related services. These services included evaluating the
<br />performance and conducting operation and maintenance of 24 different types of BMPs, including: Media Filters,
<br />Wet Ponds, Dry Detention Ponds, Bioswales and biostrips, Infiltration Basins and Trenches, Hydrodynamic
<br />Separators, Catch Basin Inserts, and Oil/Water Separators. Mr. Schaedler also led a three-year, $5 million statewide
<br />study to characterize runoff from various Caltrans facilities, including freeways, maintenance stations, park and rides,
<br />rest areas, and toll plazas using automated monitoring equipment. This study has supported the development of
<br />pollutant load models and TMDLs, compliance with NPDES permits, and evaluation of applicable BMPs.
