Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Colusa County
Tentative parcel maps: Colusa County Code, Appendix IV (Ordinance No. 377), Section 5 "Specific procedures – Final maps, parcel maps, lot line adjustments, and mergers" — see §5.13(b) (tentative parcel map submittal) and §§5.14–5.15 (agency distribution/review). Vesting tentative maps are separately codified at Chapter 39 (https://www.codepublishing.com/CA/ColusaCounty/html/ColusaCounty39.html).
Submittal checklist →Recorded live at both URLs on 2026-07-04. The Appendix IV page loads directly (verified via curl since WebFetch returned 403 on this host). No single itemized 'submittal checklist' PDF was found; the closest official document is the Planning & Building Dept's 'Land Divisions — General Information and Overview of the Process' handout (DocumentCenter/View/663), which describes required submittal items (application, map prints, title report, fees) in narrative form rather than a checklist grid. Confirmed county Land Divisions overview also references 'application submittal requirements' as a separate item Planning staff can provide on request — could not locate that document online.
Source: 'SURVEYOR FEES PER RESOLUTION NUMBER 96-3 ADOPTED BY THE BOARD OF SUPERVISORS ON JANUARY 9, 1996,' currently published live on the county's Public Works Fee Schedule page (fetched and confirmed via curl 2026-07-04). This is the only source found — no second corroborating document (staff report/resolution PDF) turned up in search; treat as single-sourced. Note the fee schedule is dated 1996 but is what the county currently publishes as authoritative in 2026.
From the Colusa County Clerk-Recorder's official '2026 Schedule of Fees' PDF, MAP FEES section, citing Government Code §§27372, 27361.4. Downloaded via curl and extracted with pdftotext -layout (WebFetch could not render this PDF). Single source — it is the primary/authoritative fee schedule itself, so no second source was sought.
City of Colusa
Tentative parcel maps: Code of Ordinances, City of Colusa, Chapter 17 "Map Filing and Processing," Article III "Parcel Maps" (confirmed section heading '§17-32. Grounds for denial., Article III. Parcel Maps., Chapter 17. Map Filing and Processing' via a mirrored index at colusa-ca.elaws.us).
Municode blocks WebFetch/curl on this host with a 403 (Angular SPA, JS-rendered); chapter/article/section identification was corroborated two ways: (1) Municode's own search-result title 'CHAPTER 17. - MAP FILING AND PROCESSING. | Colusa, CA' at this URL, and (2) an independent mirror (colusa-ca.elaws.us) whose page title read '§ 17-32. Grounds for denial., Article III. Parcel Maps., Chapter 17. MAP FILING AND PROCESSING., Code of Ordinances, Colusa' — the elaws mirror itself was down (503) at time of verification so its content could not be directly re-fetched, only its indexed title snippet.
