Steps

  1. Recognize most state DOT 'approved products' or 'product acceptability' lists for erosion control (rolled erosion control products, hydraulic mulches, etc.) are published as static PDFs or web pages, not structured/queryable datasets.
  2. For Wisconsin, use WisDOT's Erosion Control Product Acceptability List (PAL) page (wisconsindot.gov/Pages/doing-bus/eng-consultants/cnslt-rsrces/tools/pal/default.aspx); underlying documents are served from the state's CONTENTdm-based digital-document repository (wistatedocuments.org), which offers document retrieval, not a product-attribute API.
  3. For Minnesota, use MnDOT's Approved Products - Erosion Control and Stormwater Management page (dot.state.mn.us/environment/erosion/approved-products.html), again a web/PDF list.
  4. Plan workflows around periodic manual download-and-parse of the current PDF/page, and confirm the list's effective/revision date before citing specific approved products.
