Summary
When weeds on a vacant Rohnert Park lot become a fire menace or public nuisance, the city council can declare it a nuisance by resolution, order the owner to clear it, and, if the owner doesn't, send crews to abate it and bill the cost against the property as a special assessment.
Whenever any such weeds are growing upon any private property or in any street or alley within the city, the city council shall pass a resolution declaring the same to be a public nuisance, and order the city manager to give notice of the passage of such resolution as herein provided and stating therein that unless such nuisance be abated without delay by the destruction or removal of such weeds, the work of abating such nuisance will be done by the city authorities or their designated agents or contractors ... the city council shall by resolution order the city manager to abate such nuisance, or cause the same to be abated, by having the weeds referred to destroyed or removed; and the city manager and his deputies, assistants, employees, contracting agents, or other representatives are expressly authorized to enter upon private property for that purpose. ... All special assessments against such respective lots or parcels of land are due and payable within thirty days after the date of confirmation by the city council at the office of the city, Rohnert Park, California. In the event that the charge is not paid within the time, and at the place so provided, there shall attach to the charge a penalty of ten percent.

Full Breakdown
08 governs how the city forces cleanup of an unmaintained lot, improved or vacant. 020, once weeds bearing seeds of a wingy or downy nature, or grown large and dry enough to be a fire menace, or otherwise noxious or dangerous, are found on a lot, the city council passes a resolution declaring the growth a public nuisance and directs the city manager to notify the owner that the nuisance must be abated without delay or the city will do the work itself and assess the cost.
040. 060 authorizes the city manager and city crews, contracting agents, or other representatives to enter the private property to destroy or remove the weeds, though the owner may still do the work personally before the crew arrives. 100 makes the abatement cost a special assessment against the lot, due within thirty days of the council's confirmation of the cost report; an unpaid assessment draws a ten percent penalty plus an additional one-half of one percent per month until paid. 010 applies to 'any private property' without distinguishing improved from vacant parcels.
Violations & Fines
An owner who ignores a Chapter 8.08 nuisance resolution faces the city abating the lot itself and assessing the full cost, plus a ten percent late penalty and one-half of one percent per month if the assessment goes unpaid under § 8.08.100. Independently, letting solid waste accumulate on a vacant lot is enforceable under § 8.12.170 as an infraction, up to $100 for a first offense and $500 for repeats within a year, with summary abatement and a property lien available for the cleanup cost.
