If inspection information warrants action we will discuss with Board. Easement Issues • Las Lomitas was not a Local Improvement District, City-owned or Developer constructed sewer system. • This annexation was unique and not well documented. • Property rights of District not clarified at time of annexation. 3 June 11, 2018 EOPS Regular Committee Meeting Agenda Packet- Page 17 of 23 Page 11 of 12 Current Property Rights Issues • No recorded grant of easement or formal dedication of property rights to the District. • Two main issues: • Notice to current and future owners and other parties holding property rights(lenders,other easement owners). • Obtaining unequivocal legal easement rights. Easement Notice Issues • In the 1970's— District provided notice by recording declaration against subdivision. • This action has not provided adequate notice through title reports. • 2008— notice by recording declaration against each parcel. • Declaration should be reflected in most title reports. • This action does not create "constructive" legal notice. • Future notice—could also record declaration in grantee- grantor index. • This might increase listings in title reports. • This action would not create "constructive" legal notice. 4 June 11, 2018 EOPS Regular Committee Meeting Agenda Packet- Page 18 of 23 Page 12 of 12 Remaining Easement Issues • Notice issues. •Actual notice v. "constructive" notice. •Current owners have actual notice, but not "constructive" legal notice. • Notice v. undisputed legal easement rights. •Actual notice will minimize problems with existing and new property owners. •Notice does not create easement rights. •Must obtain grants of easement or a judgment to perfect easement rights. Legal Conclusions • Existing notices should minimize, but not eliminate, conflicts with property owners. • Only means to fully eliminate conflicts over easement rights is to obtain grants of easement or obtain a judgment. 5 June 11, 2018 EOPS Regular Committee Meeting Agenda Packet- Page 19 of 23
