Downspout & Gutter Drainage in Homeland

Downspout & Gutter Drainage questions from Homeland customers

Where should downspouts discharge at a manufactured home in Homeland?

Away from the underfloor space. California Code of Regulations Title 25 section 1116 requires each lot in a mobilehome park to be graded to prevent the migration of water to the underfloor area of a unit, accessory building or structure. It also requires that the area beneath the unit be sloped to drain to an approved outside drainage way for any unanticipated water that does get in.

Water is getting under the home after storms — what does the state expect?

The state's mobilehome installation guide, published by the Department of Housing and Community Development in 2007, states that each mobilehome lot or site shall be graded to insure that water cannot accumulate beneath the unit, and that all vegetation shall be cleared from the area of the lot beneath the unit. Roof discharge landing at the skirting line works against both.

Can a downspout line be taken out through the curb in Homeland?

County drawings cover it. Riverside County's road standards, adopted under Ordinance 461.11 and effective March 2, 2023, include Standard 308 curb outlet drain, Standard 309 under sidewalk drain cast in place, and Standard 310 private drain through curb. Because Homeland is unincorporated, those county details rather than a city's own standard plans govern how a roof leader line is finished at the frontage.

The park road ponds after rain, not my lot — is that covered by anything?

Title 25 section 1116 addresses it directly. The park area and park roadways shall be graded so that there are no depressions in which surface water will accumulate and remain for a period that would constitute a health and safety violation as determined by the enforcement agency, and the ground shall be sloped to provide storm drainage run-off by surface or subsurface drainage facility.
