storm sewer pipe with manholes and ditch inlets along one side of Argon Street, and to outlet the storm sewer into the existing stormwater pond south of Alpine Drive between Argon and Barium Streets. Due to the estimated cost of up to $500,000, the Committee directed Staff to explore more cost-effective options. Following discussions between the Public Works Committee,the property owners of 15410 Argon Street, and Staff during the July Public Works Committee meeting, Staff enlisted the services of Bolton&Menk to collect topographic survey data across several properties along Argon Street and Barium Street for the purpose of determining the allowable grading extents on 15410 Argon Street, and whether completing grading on this property would have adverse impacts on properties downstream. Staff received the topo survey data on the afternoon of August 18th as this case was being prepared for publication. Staff will therefore have to present their findings during the meeting. If possible, Staff will attach information to this case in advance of the meeting. Timeframe: Staff anticipates 20 minutes will be required to present this case and respond to questions. Observations/Alternatives: Staff will inform the property owners at 15410 Argon Street that the survey data will be reviewed and discussed during this meeting,but that Staff will not yet be prepared to request a recommendation for the City Council. If the survey data indicates that a small grading project would be feasible without negatively impacting properties downstream, Staff may request consensus direction from the Committee as to next steps. Attached is a copy of the letter with attached figures that was mailed to area residents prior to the collection of topo survey data. Funding Source: Dependent on discussions. Recommendation: Dependent on discussions. Action: Dependent on discussions.
