The city of Sacramento, invoking its water shortage contingency plan, asked residents Wednesday to reduce consumption by 10% as California’s drought intensifies. City Manager Howard Chan moved the city into Stage 1 of its contingency plan, which mandates a 10% cut by city government and a voluntary call to residents and businesses to do the same, according to spokesman Carlos Eliason. If additional measures need to be taken, they would require action by the City Council.
