Innovative Project Delivery Practices Successfully Pioneered by the Los Angeles Green Stormwater Infrastructure Program
« All Publications

The Green Stormwater Infrastructure Program of the City of Los Angeles represents a multi-million program focused on accelerated delivery of projects providing water quality (TMDL Compliance), water supply (local water resource development), drainage, community, and local economic benefits, while providing cost and schedule surety to the project owner, the City of Los Angeles.

The Program started with suites of projects less than $1M. Currently, approximately $18M in green infrastructure is planned and/or in construction, mostly in the public Right-of-Way. Future phases of the program are contemplating utilization of private properties.  Challenges associated with COVID-19 have complicated implementation; however, the robustness of the program includes mechanisms to offset these challenges.  The intent of the Program is to expand to allow for Public Private Partnership innovations that are scalable, can maintain delivery of Key Performance Indicators, can manage associated risks and offer triple-bottom line (environmental, social equity, and local economy) sustainable benefits.

  • An explanation of the purpose of the presentation.  This presentation shares proven concepts to accelerate implementation of green infrastructure, which are often required for MS4 and TMDL Implementation compliance, maintaining cost surety and performance quality. These efforts are particularly challenging during the time of COVID-19.
  • A brief description of the main ideas. Main concepts are utilization of performance-based metrics and integrated delivery techniques to assure Key Performance Indicators are achieved, while allowing for innovation, focused on project delivery. KPIs are not limited to water quality, but also significant, quantifiable and monetizable water resources benefits (recharging of local aquifers), workforce utilization goals (small, disadvantaged businesses), and local drainage infrastructure.  The approaches are scalable and adaptable to apply to other jurisdictions.
  • A summary of the tools, ideas, and concepts that audience members can apply:  Some of the key tools and concepts are 1) Integrated Project Delivery/Progressive Design-Build delivery, 2) Collaborative Risk Registers, and 3) Development of Local Capacity (small business) Incubators.
  • A statement of how the speaker will engage the audience to make it an interactive experience:  Speakers will seek to share/understand agency concerns and needs through initial polls, electronically if CASQA infrastructure allows, or using a chat feature.
  • A statement on how the content will address the conference theme: This technical presentation will illustrate the City's implementation of Sustainable Stormwater Management, not only for water quality, but as a vital component of California's water resources, and specifically the creation and development of local water resources. The program not only engages in  communities, it also serves as an ability to create local jobs and capacities for green infrastructure development.
