CWMS Data Authorization Project Overview

This page contains meeting notes and other documentation related to progress on a contract to improve data operations and security. While the majority of data in the CWMS database is public by law, some data we store must be private, or at least have release delayed in time by various agreement with those entities that own that data, such as a privately owned dam upstream of a flood control project.

The information is being stored here given a need to have a record of it, and in the interest of transparency. We ask that anyone that isn't USACE staff that work on this project, or the vendor doing the work, refrain from editing this page. If there are points of concern you wish to address please open a discussion about it so it can be addressed.

Meeting Detailed notes

Note: a Powerpoint deck was used to drive the meeting: see here: USACE CWMS Kickoff Meeting Presentation 2025.05.19.pdf

Agenda Item #1: Introduction of the teams

All team members from both sides were introduced, with tiles and job roles described. The project team for both the Government and the Contractor are as follows:

From SolidLogix:

• Jorge Hassan - SolidLogix CEO, Executive Sponsor & Solutions Architect.
• Milver Valenzuela - SolidLogix COO, Project Director.
• Todd Boss - Project and Data Manager.
• Ryan Cunningham - Senior Software Engineer.
• Christina Whitehead - Business Analyst.
• Vairav Laxman - Software Engineer.

From USACE HEC:

• Michael Neilson - main technical POC, COR
• Charles Graham - district staff member for ACE, community outreach/front-end
• Eric Novotny - data team lead for water management section, database development
• Fauwaz Hanbali - senior hydraulic engineer During the team introductions, the HEC team described the technical scope: CWMS Data API, time series authorization, cloud migration context, and stakeholder access goals.

Agenda Item #2: Verify current source code locations methods of contribution

The team discussed the current technical makeup of the project, discussed communication, tooling, and other development topics.

• CWMS API is hosted publicly on GitHub – Solid Logix will fork it for contribution.

• Docker Compose setup with local Oracle database image is available for local dev/testing.

• HEC will share a ready database image, schema repo, and setup guides.

• HEC to grant GitHub repo access and create DevNet SSO/rocket.chat accounts for Solid Logix team.

• Fork-first development model will be followed; internal contributions may be considered later.

• Rocket.Chat + Discourse to be used for real-time communication and stakeholder engagement.

• Focus is on time series authorization and integration into the existing CWMS Data API.

• Local schema includes metadata but not time series data – HEC can provide loading tools.

• No CAC required now – if needed later, they'll work to expedite it.

• Target architecture is cloud-first; PostgreSQL is preferred long term, but Oracle is current baseline.

• Unit/integration tests will be run through GitHub Actions.

• HEC is open to sharing real use cases, success criteria, and sample data once accounts are in place.

• Mike to provide list of stakeholders for interviews.

• HEC emphasized “open, opinionated, and collaborative” community culture.

Agenda Item #3. Scheduling the regularly occurring meetings The team discussed meeting cadence, plus discussed documentation initiatives and talked about other Project Management issues.

• Bi-weekly meetings to be scheduled starting Monday, 5/27 @ 11AM EST / 8AM PST
• Next Monday is a Federal Holiday: we’ll do a one-off Tuesday 5/28 meeting, then return to every other Monday cadence.
• Todd will manage the cadence, project board (GitHub Projects), and wiki structure.
• We will use GitHub Projects to do Task tracking
• We will use GitHub Wiki for online documentation.
• GitHub wiki and Issues will serve as the single source of truth for docs, MFRs, and meeting notes.
• Formal MFRs (Memos for Record) will be used when decisions are finalized.
• Both sides are on the same page w/r/t transparency and documentation, and we’ll do our best to use the tools and to document as much as possible.

Agenda Item #4: General questions and Next Steps. General Questions as documented in the Kickoff deck; the five major subject areas to cover were:

1. Source code & Collaboration
2. Environment & Infrastructure
3. Authorization Design Input
4. Stakeholders & Meetings
5. Additional Considerations.

Questions or blockers? Reach out via email or rocket.chat once available. The USACE team endeavors to be as responsive as possible, given their role as government employees.

All Next Steps are captured as Action Items with assignees.
