for all County infrastructure projects
• Expand the use of Envision
• Coordinate with Cities and
other agencies
• Reach out to construction and
small business community
How Public Works Uses ENVISION
• Change how we manage infrastructure
• Incorporated into initial Project Concept
Reports and Design Plans
• Programmatic Approach
• Development Planning
• Contracts and procurement
Category Project Type Description Notes
Significant
Pipe Lines Install various size diameter pipe below grade PCR Process – Uses as-
needed design contract
Pump Stations Construct pump station inc. the building 5 consultants – Uses select list
process
Reservoirs (Water Tanks) Construct steel/concrete reservoir
Reservoir Repairs (Water
Tanks)
Repair/upgrade existing reservoir to current AWWA
standard
Pressure Reducing
Regulating Stations
Construct pressure reducing regulating station including the
building
Groundwater well(s) Drill and construct groundwater well approx. 500 to 1500
feet below grade
Solar Carport or field Construct a solar carport or field projects to reduce the
Districts’ energy costs and be more sustainable
Routine
Valve Maintenance Field staff exercise existing below ground valves Programmatic approach.
Federal funding supports local
purchasing.
Identify local products
Routine leak repairs Field staff and/or emergency contractor doing leak-induced
repair work
Programmatic approach.
Routine Reservoir
Recoating/Painting and
other tank maintenance
tasks
-Recoating the interior of steel tanks is required every 20
years to maintain the expected service life
-Painting the exterior of steel tanks is necessary every 10
years to maintain the expected service life
- routine visits, condition assessment and minor repairs
Programmatic approach. NSF
approved products only.
Check on material specs for
things like paint. Choose the
environmentally sustainable
option.
Groundwater well
rehabilitation
Existing groundwater wells require routine maintenance to
maintain production over its service life
Programmatic approach. Local
products and recycled
materials.
Water Meter Existing water meters need to be upgraded to smart or

Editor's Notes

  1. Good afternoon everyone, I currently head our strategic planning and sustainability office on department wide sustainability initiatives such as the implementation of the Envision rating system. Today I’m going to tell you a bit about my department’s history with the Envision rating system, how we are expanding its use throughout our department and other county departments and give you an example of a project that we submitted for third party verification.
  2. The County is over 4,700 square miles and home to 10 million residents, 1 million of which live in our unincorporated communities. The county is made up of 88 different cities and over 140 unincorporated communities. That is 88 different city governments with their own public works departments and their own priorities for infrastructure improvements.
  3. Los Angeles County Department of Public Works is one of the largest Public Works Departments in the nation and has annual operating budget of over 2.4 billion and employs over 4000 people. It was formed in1985 when the County Engineers office was combined with the Road Department and the County Flood Control District. The department is broken up into 6 core service areas – Water Resources, Transportation, Environmental Services, Public Buildings, Development Services and Emergency Management. These core service areas cover all aspects of civil infrastructure. The department is responsible for 14 major dams, 27 spreading grounds over 3000 miles of storm drain system, 533 bridges, and over 3000 miles of county roadway.
  4. The County as a whole and the Department of Public Works in particular has always placed a high value on sustainability. Investing in sustainability is one of the key focus areas of our strategic plan which sets the direction for our entire department. Our administration is committed to community based infrastructure planning to provide the most sustainable programs, services and infrastructure possible to our unincorporated communities.
  5. Public Works has been involved with the Institute for Sustainable infrastructure since 2011 and began extensively rating projects in 2013. We have now rated 118 projects. Of those, 60% qualified for an award and of those that qualified 70% were in the Bronze to Silver range and 30% were in the gold to platinum range. Not all of these projects were designed from the start with Envision in mind. We decided to go through the effort of rating some of our existing projects to get a sense of where our typical projects stand and what award level they might achieve. To us Envision is about a lot more than just an award, in fact we’ve only ever submitted one project for a third party verification and I’ll go into a little bit more detail on that project in just a few minutes. The real value that Envision brings for us is having a consistent language to discuss and measure sustainability across all of our various core services form transportation to environmental services.
  6. After having rated some projects and seeing the benefits of a consistent sustainability language within our own department we worked closely with the County Board of Supervisors to adopt Envision as a standard for all County Infrastructure projects. In August 2016 the Board passed a motion which expands the use of Envision beyond Public Works to all departments that have infrastructure projects. It also directed us to develop a consistent sustainability language by coordinating with other agencies in the region such as the City of LA and Los Angeles County Metropolitan Transportation Authority (Metro) on joint projects using the envision rating system. Also reach out to make impact on private sectors including construction and small business community
  7. Our design division had been using it for quite some time, but not every division was using it and we are really looking to institutionalize the use of Envision in all our processes. To that end we established a department working group made up of representatives from each of our core service areas and we analyzed the various types of projects that were being developed in each area. We are also looking at expanding Envision beyond the traditional infrastructure project to utilize it in even early in the planning process.
  8. We broke projects down into two main categories, significant and Routine. This table represents one example project breakdown for our waterworks operations. The larger more significant projects require a project design concept, sometimes prepared in house and sometimes by a consultant. These projects will have Envision applied through the design concept process. The smaller more routine projects do not have the same design concept process because they are a little more prepackaged and don’t need as much conceptual design work. However we wanted to find a way that we could still make these projects as sustainable as possible without increasing the cost, so we identified them for a possible programmatic approach. We are still working on developing these programmatic ratings for routine projects but here is one example.
  9. This table represents a programmatic rating of our pavement preservation program. Our road maintenance Division and Geotechnical and materials divisions identified all the envision credits that our pavement preservations projects should be able to achieve. You can see that it is heavy on the leadership category because of our departments policies on sustainability and it is also heavy on the resource allocations side, for things like using local and recycled materials, and diverting waste from landfills. This establishes the minimum point value that all pavement preservation projects should achieve based on current practices and allows us to look for areas to improve such as infrastructure integration and emissions reductions.
  10. As part of incorporating Envision into our Design process We’ve developed what we refer to as sustainable infrastructure design guidelines. The Guidelines utilize and integrate sustainable best practices and design criteria into the following 7 categories: These guidelines help designers decide what sustainability features to incorporate into their projects. The guidelines were designed with Envision in mind but also include features from LEED and the California Green Building code as well as other existing design guidelines. Designing a project following the steps and elements in the Guidelines will automatically implement the sustainability principles of Envision, leading to a high Envision rating.
  11. By selecting a public works project type a checklist is prepopulated with the credits that are most applicable to that type of project and those that are not. This gives the designers a good place to start when considering what features to include in their projects. Following the guidelines and implementing the sustainability measures recommended will start a project out right around a silver Envision rating depending on the project, then it is up to the design team to decide if they should pursue additional sustainability measures.
  12. As I mentioned Public Works sometimes uses contractors to assist with the development of project design concepts so we saw a need to develop specific contract language requiring consultants to have ENV SP credentialed staff and discuss their experience using Envision in their RFP proposals. They are also required to use the Envision rating system and the SIG when developing a Project Design Concept Report. Importance of Government procurement and contracting to transforming the industry
  13. Once the Board motion was passed we really began to look at ways to expand the use of Envision within our own department. We are working with our Department of Regional planning to explore the possibility of using Envision to inform their long term planning projects and their development of specific plans and community plans.
  14. Final Score = 67% Now really quickly I’d like to take you through our Sun Valley Watershed Management Plan which we submitted to ISI for verification and received a platinum award. The watershed management plan was a comprehensive plan for the sun valley watershed that included an extensive public outreach process that was used to develop the plans objectives which were increasing flood protection improving water quality, increasing water conservation, providing more open space and recreation opportunities in the watershed and restoring wildlife habitat.
  15. As we move forward with Envision Implementation we are continuing to incorporate it into our infrastructure design processes and we are developing a formal Envision policy within the department to memorialize all the work we’ve done over the past year to determine how Envision should be implemented. We are also developing a database to track our progress and identify areas for improvement, we are continuing to outreach to our small business and contracting communities and we are working closely with other agencies such as the city of LA and Metro, who also recently adopted Envision as a standard for their infrastructure projects.
