Dear Friends, Family, Colleagues and Clients,

Happy Holidays! CDIM is grateful to our clients, partners and contractors for another year of continued collaboration. I write now to 1) wish you all the best fortune as we roll into a new decade and 2) give a short update on CDIM’s activities over the past year.

In 2019, our firm continued to slowly and cautiously expand. In November, we added a senior staff geologist.  Amie Hinds joined our team of four engineers and one GIS/data specialist.  We also added a new Joint Venture partnership and a contract with the Port of San Francisco, which resulted in the expansion of our existing business insurance and accounting practices. We continued to expand our in-house graphics capability by adding new software capacity, training and skills. We expanded our field services by developing new field quality assurance procedures, adding new equipment/measurement devices and adding partnerships with excavation, waste disposal, and material supply firms. We continued to expand our outsource relationships with marketing and accounting firms.  We gained a local international airport as a client and expanded the services we provide to local law firms. CDIM also had the opportunity perform a market analysis of the California’s hazardous waste industry that we published in the ASCE’s Hazardous Waste Infrastructure Report Card.


While continuing to provide our core assessment/remediation, site civil engineering, water quality and regulatory compliance services, we saw an expansion in sediment, air quality, and asbestos monitoring.

  • We supported sediment remediation at a Superfund site, began assessing PAHs in sediment at another site, and have been contracted to provide dredge characterization and permitting.

  • We estimated air emissions from two large industrial processes, monitored and assessed air quality using real time measurement devices, and performed air dispersion modeling and health risk assessment for a new process using BAAQMD/CARB models. 

  • We assisted in entitlement planning for a new housing development in San Francisco and commissioned a water treatment system that we designed the year before.

  • We performed numerous asbestos assessments to support disposal projects and construction air monitoring projects that involve earthwork and naturally occurring asbestos.

In the most explosive moment of the year, we helped a local sheriff’s department bomb squad detonate an old dynamite (weeping nitroglycerin) that had become shock sensitive!

Through business operations that lead to a modest profit, we were able to provide charitable donations to the following organizations:

  • San Francisco Court Appointed Special Advocates for abused and neglected children in foster care. www.casasf.org. CDIM has support SFCASA since our inception. 

  • Downtown Streets Team provides a work experience program that empowers individuals and acts as a steppingstone into employment, housing and a better life. The Civic center team can be seen performing trash removal on mornings in SF Civil center where our office is located.   www.streetsteam.org 

  • Samaritan House is the largest food distribution agency in San Mateo County. This is the first year for CDIM to support the Samaritan House.  www.samaritanhousesanmateo.org

We are fortunate to have started CDIM during a time of economic growth, and we remain grateful to all of our clients and partners for trusting us this past year.  We wish you all a peaceful close to 2019 and prosperity and joy in the year and decade to come!

Thank you,
