Stormwater Experience

Storm Water Engineering Indefinite Quantity Contracts, Naval Facilities Engineering Command, Southwest Division, Various Southwest US Locations. Engineering Fee $30 million. Mr. Fraser was the Senior Executive in Charge. Fifteen years of ongoing contract awards. The scope included master planning and design of storm water management plans, storm water pollution prevention plans (SWPPP), permit preparation and permit renewal, laboratory analysis, long term monitoring and program management and GIS mapping and administration.

Southern California Coastal Water Research Project for Santa Monica Bay and Los Angeles River Watersheds, CA. Senior Project Executive. This contract includes various studies in support of developing water quality models that will be used to support total maximum daily load (TMDL) assessments in the Santa Monica Bay and Los Angeles River watersheds. Scope included Storm Drain Temporal Variability Study, Post-Fire Monitoring, Pilot-Scale BMP Studies, Natural Loadings Study and Wet Weather Monitoring Program.

BMP Retrofit Pilot Program for Caltrans, San Diego, CA. Senior Project Executive. Developed site-specific OMM Plans which were used to assess drain inlet inserts, biofiltration swales and strips, infiltration basins, infiltration trenches, and continuous deflective separation (CDS) units. The approach allows for objective comparison of each BMP based on performance in removing pollutants and the associated maintenance costs. Development of a two-volume plan provides field crews with essential operation, maintenance, and monitoring protocols, while providing necessary detail to facilitate use in full BMP deployment throughout Caltrans freeway systems. The OMM Plans provide detailed guidelines for monitoring and recording maintenance activities at each BMP site including:

  • Storm water sample characteristics,
  • Flow into and out of the BMP,
  • Analyses of influent and effluent flow-weighted composite samples collected by automated monitoring equipment,
  • Analyses of influent and effluent grab samples,
  • Empirical observations on the performance of the BMP during storm and post-storm periods, and
  • Man-hour and equipment-hour requirements for maintaining the BMP, and the resulting costs. A Maintenance Indicator Document provides a long-term protocol for maintaining the pilot BMPs. This encouraged consistency and control efficiency of maintenance and operation of the BMPs.

BMP Retrofit Pilot Program Continuous Deflective Systems for Caltrans, Los Angeles and San Diego, CA. Senior Project Executive. The scope of work of this project was to operate, maintain, and monitor two Continuous Deflective Separation Units. Our approach enabled cost-effective monitoring of storm events to evaluate the performance of the CDS units related to both water quality benefits and gross pollutant removal efficiencies. The level of effort required to operate and maintain the units at their optimal effectiveness was also assessed. MACTEC developed an innovative technique for measuring the amount of sediment captured by the units by measuring wet and dry weights and then incinerating the gross pollutants. The performance evaluations of the CDS units consisted of characterizing the types and amounts of gross pollutants captured within the CDS units and calculating removal efficiencies for gross pollutants, individual water quality constituents, and inorganic (non-volatile) solids. Observations were also made during storms to assess whether the CDS units performed as designed. A final report was prepared with detailed documentation for each BMP site.

BMP Retrofit Pilot Program for Caltrans, Los Angeles and San Diego, CA.  Senior Project Executive. This scope of work was selected to operate, maintain, and monitor 24 BMP pilot sites throughout Southern California. Provided expertise in monitoring equipment selection to cost-effectively and accurately measure storm water runoff characteristics; trained local staff, which allowed immediate mobilization to monitor BMP sites during storm events; and communicated daily with Caltrans to provide real-time comprehension of site conditions and monitoring activities. Detailed records were maintained for each of the BMP sites to document all aspects of the project. A final report was prepared with detailed documentation for each BMP site.

Monitoring ASBS/SWQPA'S Sites for Caltrans Districts 1, 4, & 5, CA. Senior Project Executive. Key elements of this project included sited and installed three automated samplers under rigorous siting conditions in remote locations; Installed five automated samplers with remote data management and remote sampler programming capabilities in remote locations at three ASBS sites and two reference stream sites; Obtained permits for work within and outside of Caltrans Right of Way; Preparation of project-specific sampling and analysis plan guided by Caltrans protocals; Development of a cost-effective quality assurance/quality control plan; Preparation of Health and Safety Plan that is compliant with Caltrans Manual of Traffic Controls and accounts for hazardous aspects of sampling in remote locations; Flexible mobilization of field teams including mobilization for sampling on Easter Sunday; Monitoring documentation and reporting; Gathered and validate data from analytical laboratory using Caltrans' Monitoring and Characterization Data Base validation software to assess analytical data.
