March 12, 2013 WHEREAS, the Commonwealth Transportation Board has established procedures for allocation and distribution of funds provided; and WHEREAS, a resolution expressing Portsmouth City Council's continuing support of the application has been requested by the Norfolk and Portsmouth Belt Line. NOW, THEREFORE BE IT RESOLVED by the Council of the City of Portsmouth, Virginia, that it hereby supports the application of the Norfolk and Portsmouth Belt Line to the Virginia Department of Rail and Public Transportation for Rail Preservation Program funds to be used for its crosstie replacement improvement project." Ayes: Cherry, Edmonds, Meeks, Moody, Psimas, Randall, Wright Nays: None 13 - 120 -Adoption of a resolution authorizing the Department of Public Utilities to exceed by 25% or more, the contract with Wiley/Wilson for the Portsmouth Dams Alteration Designs. Vision Principle: Efficient, Responsive Government. Background: • The City, through its Department of Public Utilities, owns and operates three earthen dams as part of a network of lakes that serve as the City's water supply. These dams are located in the City of Suffolk and form Lakes Cahoon, Kilby and Speights Run. These are three of the four lakes that provide drinking water to the City. • Updated dam safety regulations require certain improvements to be made to these three earthen dams to help prevent possible erosion or dam failure. • A Preliminary Engineering Report (PER) was prepared by Wiley~Wilson in September 2010. The PER addressed the improvements needed to bring the earthen dams into compliance with the updated safety regulations. The estimated construction cost of these improvements is between $3.9 million and $4.4 million. • The Department of Conservation (DCR) recently revised their recommended processes to show compliance with the new regulations. Discussion: • Wiley~Wilson has performed additional surveys and flood modeling of the properties impacted by a potential dam failure. This work was performed as a result of the recently revised DCR recommendations. In addition, actual lake level data from Hurricane Floyd in 1999 was compared with potential dam failure models. Coupled with extensive discussions with DCR, the result of this work by Wiley~Wilson has reduced the extent of the improvements required at the earthen dams. Financial Impact: • Approval of the Resolution and subsequent change orders will add approximately $40,500 in additional expense to this project. o Including previous change orders, the original contract amount will increase approximately 49%, from $138,235.00 to $206,040.00. • With the additional work performed by the Engineer, the new construction estimates are between $2.8 million and $3.3 million, a total potential construction savings of $1.1 million. • Funds for these dam improvements are available in the Public Utilities Capital Budget and will fund this additional expense. Recommended Action: Adoption of the resolution. Vision Principle: Efficient, Responsive Government. Next Steps following City Council Action: • Project design will be completed to comply with all DCR design and safety standards and finished construction documents will be sent out for bid. Motion by Mr. Moody, and seconded by Ms. Psimas, to adopt the following resolution, and was adopted by the following vote:
