πŸ”₯ ACTION: Extract CDP URLs

# Each CDP deployment has a GitHub repo with config
# Example: https://github.com/CouncilDataProject/seattle
# Config file contains the source URLs for that jurisdiction

cdp_jurisdictions = [
    {
        "name": "Seattle",
        "state": "WA",
        "cdp_url": "https://councildataproject.org/seattle",
        "source_repo": "https://github.com/CouncilDataProject/seattle"
    },
    # ... (all 20+)
]

Expected Coverage: 20 high-value jurisdictions with full data pipelines already built


πŸ” THIRD PRIORITY: Legistar Subdomain Enumeration

Why: Legistar is used by 1,000+ municipalities
Pattern: {city}.legistar.com or {city}-{state}.legistar.com

Known Legistar Cities (Examples):

  • chicago.legistar.com
  • seattle.legistar.com
  • losangeles.legistar.com
  • boston.legistar.com
  • phoenix.legistar.com

πŸ”₯ ACTION: Enumerate Legistar Subdomains

# Try common city names against legistar.com
# Or use DNS enumeration tools

legistar_pattern_tests = [
    f"{city.lower()}.legistar.com",
    f"{city.lower()}-{state.lower()}.legistar.com",
    f"{city.lower()}{state.lower()}.legistar.com"
]

# Test against our 85,302 jurisdictions
# Expected: 1,000-3,000 matches

Expected Coverage: 1,000-3,000 municipalities using Legistar


πŸ“Š FOURTH PRIORITY: City Scrapers Jurisdiction Lists

Website: https://cityscrapers.org
GitHub: https://github.com/city-scrapers

Known City Scrapers Deployments:

  1. Chicago β†’ ~100 agencies/boards

    • City Council
    • Board of Education
    • Housing Authority
    • Board of Health
    • Planning Commission
    • etc.
  2. Pittsburgh β†’ https://github.com/city-scrapers/city-scrapers-pitt

  3. Detroit β†’ https://github.com/city-scrapers/city-scrapers-detroit

  4. Cleveland β†’ https://github.com/city-scrapers/city-scrapers-cle

  5. Los Angeles β†’ https://github.com/city-scrapers/city-scrapers-la

What You Get:

  • Each scraper file = 1 agency URL
  • Multiple agencies per city
  • URLs already validated (they're actively scraped)

πŸ”₯ ACTION: Extract City Scrapers URLs

# Clone City Scrapers repos
git clone https://github.com/city-scrapers/city-scrapers.git
cd city-scrapers

# Each Python file in city_scrapers/spiders/ contains URLs
# Example: city_scrapers/spiders/chi_board_of_health.py
# Contains: start_urls = ['https://www.chicago.gov/city/en/depts/cdph/...']

# Extract all start_urls from all spider files

Expected Coverage: 5 cities Γ— 20-100 agencies = 100-500 agency URLs


πŸ“‹ FIFTH PRIORITY: Councilmatic Deployments

GitHub: https://github.com/datamade

Known Councilmatic Instances:

  1. Chicago β†’ https://chicago.councilmatic.org
  2. New York City β†’ https://nyc.councilmatic.org
  3. Philadelphia β†’ https://philly.councilmatic.org
  4. Los Angeles β†’ (check DataMade repos)
  5. Miami β†’ (check DataMade repos)
  6. Denver β†’ (check DataMade repos)

What You Get:

  • City council meeting URLs
  • Legislation tracking
  • Person/vote data

Expected Coverage: 6-10 major cities


❌ NOT USEFUL: HuggingFace

Search Results:

  • 0 results for "council meetings"
  • 1 result for "local government" (Korean ordinances, not US)

Conclusion: HuggingFace doesn't have US local government datasets yet


🎯 REVISED STRATEGY

Phase 1: Download Existing Datasets (HIGHEST ROI)

Timeline: 1-2 days
Expected URLs: 2,000-10,000+

  1. βœ… Download LocalView dataset (Harvard Dataverse)

    • Likely the single best source
    • Probably has 1,000-10,000 jurisdictions
  2. βœ… Extract CDP deployment URLs (20 jurisdictions)

    • Premium quality data
    • Full pipelines already built
  3. βœ… Clone City Scrapers repos (100-500 agencies)

    • Extract URLs from spider files
    • Multiple agencies per city
  4. βœ… List Councilmatic instances (6-10 cities)

    • Major city councils

Total from Phase 1: ~2,000-10,000 URLs


Phase 2: Platform Enumeration

Timeline: 1 week
Expected URLs: 1,000-3,000

  1. βœ… Enumerate Legistar subdomains

    • Test all 85,302 jurisdiction names against legistar.com
    • Pattern: {city}.legistar.com
  2. βœ… Scrape Granicus client list

    • Check granicus.com website for clients
  3. βœ… Scrape CivicPlus client list

  4. βœ… Scrape Municode directory

Total from Phase 2: 1,000-3,000 URLs


Phase 3: Census + CISA Matching (Current System)

Timeline: Already built
Expected URLs: 1,000-2,000 additional

Keep our current system as fallback for jurisdictions not covered above.

Current results: 76 URLs from 500 tested (15% match rate)
Projected: ~5,000 URLs if we test all 32,333 municipalities


πŸ’‘ THE BIG INSIGHT

You were absolutely right to ask!

We've been trying to:

  • Match jurisdiction names to .gov domains (hard, 15% success)
  • Discover URLs ourselves (reinventing the wheel)

We should instead:

  • Download LocalView's dataset (they already did this!)
  • Extract URLs from CDP deployments (they already configured these!)
  • Use City Scrapers spider URLs (they already validated these!)
  • Then fill gaps with our Census matching

Estimated total coverage:

  • LocalView: 1,000-10,000 URLs
  • CDP: 20 jurisdictions
  • City Scrapers: 100-500 agencies
  • Legistar enumeration: 1,000-3,000
  • Our Census matching: 5,000
  • TOTAL: 7,000-20,000 URLs (vs. our current 76!)

πŸš€ IMMEDIATE NEXT STEPS

Step 1: Download LocalView Dataset (Do This NOW)

# Visit: https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/NJTBEM
# Download all files
# Expected: CSV/JSON with jurisdiction info + URLs

Step 2: Extract CDP URLs (30 minutes)

# Create cdp_deployments.json with all 20+ instances
# Each entry needs: city, state, cdp_url, source_url

Step 3: Clone City Scrapers (1 hour)

git clone https://github.com/city-scrapers/city-scrapers.git
# Write script to extract start_urls from all spider files

Step 4: Integrate Into Bronze Layer (2 hours)

# Add new tables:
# - bronze/localview_jurisdictions
# - bronze/cdp_deployments
# - bronze/city_scrapers_agencies
# - bronze/councilmatic_instances

# Then merge with our existing Census + CISA data

πŸ“Š ROI Comparison

Approach Time Investment Expected URLs Success Rate
Current: Census + CISA 2 weeks (done) 5,000 15%
LocalView Dataset 1 day 1,000-10,000 100%
CDP Extraction 2 hours 20 100%
City Scrapers 4 hours 100-500 100%
Legistar Enumeration 1 week 1,000-3,000 30-50%
TOTAL 2-3 weeks 7,000-20,000 40-80%

Conclusion: Downloading existing datasets is 10x more efficient than discovering URLs ourselves!


βœ… RECOMMENDATION

Stop trying to match Census names to domains.

Start downloading these datasets:

  1. LocalView (biggest prize)
  2. CDP deployments (highest quality)
  3. City Scrapers (validated URLs)
  4. Then use our Census matching to fill remaining gaps

This is the "stand on the shoulders of giants" approach - leverage the work already done by the civic tech community!
