Lincoln FAQ
What goes in a Lincoln ESCP?
Per LMC §13.30.090, an ESCP shows the site, drainage patterns, locations of erosion-control BMPs (soil stabilization, hydroseed, mulch), sediment-control BMPs (fiber rolls, silt fence, inlet protection), construction-entrance tracking control, material storage areas, and waste-management practices. The City references the CASQA Construction BMP Handbook for acceptable measures.
What if my project disturbs more than one acre?
You must also obtain coverage under the State Water Board's Construction General Permit (Order 2022-0057-DWQ) before grading begins. That involves filing Permit Registration Documents, paying the annual fee, obtaining a WDID number, and preparing a SWPPP by a Qualified SWPPP Developer in addition to the City ESCP.
