Agenda Item Summary:
G and G Investments, LLP is in the process of developing four lots, each zoned Medium Density Residential, with the intent to construct apartments. The proposed lots are at the very top elevation-wise of the Low Level Operational Pressure Boundary for water service. No further development can take place until a new pressure zone is constructed in this area. The extension of water mains in Neel Street and Degeest Drive will result in dead-end mains of approximately 850 feet. Infrastructure Design Criteria Manual (IDCM) Section 3.9.7 allows for dead-end water mains longer than 600 feet but less than 1,200 feet as part of phased construction with approval from the Public Works Director. Eventually the water mains could be looped in future Anamosa Street; this scenario will in all likelihood not occur until several years into the future. The developer’s engineer recognized this and submitted an Exception to allow a public water main in an easement to facilitate looping of the main. Public Works approved this request on January 30, 2020 and subsequently approved the construction plans. On July 28, 2020 the developer’sengineer submitted an Exception Request to not loop the water main and allow dead-ends. Public Works denied this Exception on August 13, 2020. On August 25, 2020 the developer’s engineer submitted an appeal to this denial, as allowed by ordinance. Public Works recommends denial of this request.
