Code to maintain these rights: Lucena (Quezon), Mandaue (Cebu); Independent component cities whose charters (as amended) only explicitly allow residents to run for provincial offices: Dagupan (Pangasinan) and Naga (Camarines Sur) Registered voters of the cities of Cotabato, Ormoc, Santiago, as well as all other highly urbanized cities, including those to be converted or created in the future, cannot participate in provincial elections. In addition to the eligibility of some independent cities to vote in provincial elections, a few other situations become sources of confusion regarding the complete autonomy of independent cities from provinces: Some independent cities still serve as the seat of government for the province in which they are geographically located: Bacolod (Negros Occidental), Cagayan de Oro (Misamis Oriental), Cebu City (Cebu), Iloilo City (Iloilo), Lucena (Quezon), Puerto Princesa (Palawan) and Tacloban (Leyte). In such cases, the provincial government, apart from already financing the maintenance of its properties such as provincial government buildings and offices, may also provide the government of the independent city with an annual budget (determined by the province at its discretion) to aid in relieving incidental costs incurred by the city such as road maintenance due to increased vehicular traffic in the vicinity of the provincial government complex. Some independent cities are still grouped with their former provinces for the purposes of representation in Congress. While 24 independent cities have their own representative(s) in Congress, some remain part of the congressional representation of the province to which they formerly belonged: Butuan, for example, is still part of the 1st Congressional District of Agusan del Norte. In cases like this, independent cities that do not vote for provincial officials are excluded from Sangguniang Panlalawigan (provincial council) districts, and the allotment of SP members is adjusted accordingly by COMELEC with proper consideration of population. For example, Agusan del Norte (being a third income-class province) is entitled to elect eight members to its Sangguniang Panlalawigan, and belongs to two congressional districts. The seats of the Sangguniang Panlalawigan are not evenly distributed (4–4) between the province's first and second congressional districts because its 1st Congressional district contains Butuan, an independent city which does not vote for provincial officials. Rather, the seats are distributed 1–7 to account for the small population of the province's 1st Sangguniang Panlalawigan district (consisting only of Las Nieves) and the bulk of the province's population being in the second district. On the other hand,
