Reclamation • LACFCD • LACDPW | Task 5 – Infrastructure & Operations Concepts

CHARETTE OVERVIEW

  • Goal
  • To brainstorm stormwater capture and storage 5 P’s (Projects, Plans,

Programs, Policies & Partnerships) Concepts & Success Criteria

  • Objectives
  • To engage in individual, small group and large group brainstorming

& discussions

  • To develop viable, effective Project Concepts for stormwater capture

and storage that can be replicated throughout the basin

  • To brainstorm supporting Plans, Programs, Policies and Partnerships

that ensure success of physical measures

  • To draft success criteria for 5 P’s

BREAKOUT GROUND RULES

  • Ground Rules
  • Everyone encouraged to participate.
  • Time together is brief, please give everyone a chance to contribute.
  • All ideas count! No judgment in brainstorming.
  • Silence cell phones; take calls outside.
  • Any other ground rules to add?

BREAKOUT GROUP INSTRUCTIONS

  • Relocate into 3-4 groups, same organization – split up
  • 3x3 Individual Brainstorm Exercise
  • Breakout Group Session Instructions

1. Map & draw PROJECT Concepts for typical sites/facilities (plan view, cross-section, doodles) 2. Brainstorm supporting Plans, Programs, Policies & Partnerships 3. Brainstorm 5 P’s success criteria 4. Prioritize 5 P’s 5. Report Out to large group (pick a reporter)

BREAKOUT GROUP INSTRUCTIONS

PROJECTS

What physical PROJECT concepts does your group recommend? Can you pull from the list of measures? Doodle your design ideas, in plan view & cross-section. Describe how it would change. What success criteria does your group want to apply? 100% stormwater capture? Triple the capacity of the basin?

PLANS

Do you need to go further up in the watershed? Do your ideas require a PLAN? What problems would this PLAN solve? What are the key concepts of the PLAN? What success criteria is needed to gage success of a PLAN?

PROGRAMS

Would a volunteer or inter-agency PROGRAM efficiently solve a problem? Perhaps a change in the operations of a facility? How would you measure a successful PROGRAM?

POLICIES

Perhaps the current POLICIES need to be changed? What politically can be done to optimize performance? What metrics measure the success of a new

  • r improved POLICY?

PARTNERSHIPS

What creative PARTNERSHIPS could solve problems effectively? How can PARTNERSHIPS maximize resources & leverage? Are there private-public PARTNERSHIPS that could support regional water supply? How can you measure a successful PARTNERSHIP?
