Install a minimum of six feet of fire hydrant waterline between isolation valve and fire hydrant assembly. See City Standard Drawing 4-4. Install watermain isolation valves at locations shown on the markup plan. Typical two at each tee and three at each cross. A minimum 10-foot easement is required to be centered over all waterlines to be owned by the City, including fire hydrant runs to 5 feet past the hydrant.
Route mainlines to vehicle accessible, or street locations.
Where street locations are not feasible, mainlines through vehicle accessible areas may be considered. Fire hydrants shall be placed within a landscaped, or traffic protected area. If hydrant can not be located in this type of area, then guard posts will be required per City Standard Drawing 4-4A. Existing utility services to be abandoned shall be capped, concrete plugged, or removed prior to backfilling. If existing valve boxes are substandard, they shall be replaced with City Standard valve boxes when adjustments are made. If the water main is determined by the City to be a critical water system, then the contractor will be required to submit, five working days prior to scheduling a tie-in, a working schedule to the Water Department for approval, including starting time, duration and manpower.
