the watsonville city council is set to hear a claim today from a mobile home park owner who says the city owes him more than 400-thousand dollars in lost rent. the claim stems from a proposal to more than double rents for most tenants at the green valley village mobile home park. park owner albert vierra says that the city had wrongfully determined that homeowners had initiated a challenge, and so the increase should have gone into effect on may 1st. the city council now must approve a resolution to reject the claim.
