compacted subgrade between the concrete curb and gutter, and then the top 3'/2 inches of reclaim material would be removed and hauled off site. Then 3'/2 inches of new bituminous pavement would be installed over the remaining compacted reclaim material, resulting in a 7-ton pavement design, which is standard for residential streets. The existing storm sewer system generally consists of concrete catch basins and pipes that drain runoff from the streets to adjacent low-lying areas. Two catch basins are located along 154th Lane and drain runoff from the street to a low-lying area encumbered by a drainage and utility easement over the northerly 75 feet of 4851 154th Lane. Three catch basins are located near the intersection of Ute Street and 154th Lane. Any storm water runoff that is not collected in these five catch basins drains to the existing storm sewer systems in Alpine Drive and Roanoke Street. The existing storm sewer system is in good condition and generally meets City design standards. The only storm sewer work proposed is resetting the castings after replacing adjusting rings and re -grouting the insides of the catch basins. Municipal sanitary sewer and water utilities do not exist in Stanhope Terrace, and the attached plans do not propose to install such utilities.

Observations/Alternatives: Observations: The proposed improvements should have a serviceable life of 60 years, assuming that proactive maintenance operations are performed regularly during the life of the improvements. Some properties may have private irrigation systems. Impacts to these systems may occur because of the proposed improvements. Staff will notify property owners in writing of the pending construction as far in advance of construction as possible to allow them time to move their irrigation system components away from construction activities. After the project is complete, property owners may replace irrigation systems in their previous locations if desired. As previously discussed, all costs to relocate private irrigation system components will be the responsibility of the property owners. However, if private irrigation systems are damaged due to negligence on the part of the City's contractor, the contractor will be responsible to repair the damage. As previously discussed, while preparing the Feasibility Report Staff observed that the Ute Street cul-de-sac is not fully located within existing right-of-way, and that no public easements exist over the areas not located within City right-of-way. Staff has therefore mailed letters to the two impacted property owners informing them of this issue and asking to meet with them to discuss the potential to obtain roadway easements over the outside edges of this cul-de-sac. Staff will continue to work with the property owners to obtain the necessary roadway easements to allow the City to reconstruct and maintain the cul-de-sac in perpetuity. If the necessary roadway easements cannot be secured before construction begins, Staff will need to consider an alternate plan. Alternatives:
