Redwood City Municipal Code Art. VI Water Main Upgrade

The following requirements shall apply to all water service areas defined in Section 38.1:

Upon the construction of a new building (except an accessory dwelling unit) (residential or commercial) or upon the performance of substantial commercial or substantial residential remodeling, a minimum eight-inch diameter water main shall be constructed from the nearest point of connection of an existing water main six-inch diameter or greater size through the entire street frontage if the existing water main serving the property is less than six-inch diameter. A smaller diameter water main may be permitted by the City Engineer when documentation is provided showing the proposed development does not require an eight-inch diameter to support the additional growth for fire protection, fire suppression, and domestic use purposes according to the City Engineering Standards and Fire Code (for properties located outside of Redwood City, the fire code of the jurisdiction in which the property is located shall apply). Before permitting a smaller diameter water main, the City Engineer shall receive confirmation from the Fire Chief or designee that the proposed modification is consistent with Fire Code requirements.

In addition, regardless of the level and size of development and remodeling, a minimum eight-inch diameter water main shall be constructed from the nearest point of connection of an existing water main six-inch diameter or greater size through the entire street frontage if:

(1) The existing water main, regardless of size, does not provide adequate flows and pressures to support the additional growth for fire protection, fire suppression, and domestic use purposes as determined by the City according to the City Standards; and

(2) A fire hydrant is required and the existing water main is less than six (6) inches in diameter.

Refer to Section 18.235 for definitions of terms used in this Section.
