system, there is an opportunity to upsize the proposed storm sewers to allow the City to address chronic drainage concerns in the residential areas adjacent to Baltimore Road. Stormwater Master Plan The 2009 City Stormwater Master Plan documented and prioritized numerous drainage problem areas throughout the City. Two large areas adjacent to Baltimore Road were identified as having high priority drainage problems that need to be addressed. One location, commonly referred to as the 32nd &Fulton Area, encompasses approximately 236 acres. It is bounded by 32nd Street on the west, Rt. 36 on the north, Blaine Lane on the east and Maryland Street on the south. This drainage area was rated as the 3`d highest priority in the City due to the number of households it affects and its contribution to sanitary sewer backups. A second location that ranked 14 on the priority list is a 57 acre neighborhood that lies south of Fitzgerald Road and east of 34h Street that is commonly referred to Fitzgerald & Fontenac. This subdivision was constructed so that the drainage traveled through the back yards of the residences resulting in very limited storm sewers serving the area. These two areas will benefit greatly from the ability to drain into the proposed Baltimore Road storm drainage system. Finding good reliable discharge points is a significant stepin relieving chronic flooding problems that plague many areas of the City. Professional Services Agreement With Chastain and Associates performing the Baltimore Road design work for Macon County, City Staff requested a scope and design fee estimate from them to review drainage concerns in the area and perform a preliminary design that will recommend size increases to the County's proposed storm system. Chastain&Associates is very familiar with the area and already has much of the background data required. This preliminary design project will evaluate the existing conditions of the drainage problem areas adjacent to Baltimore Road and determine what portions could be drained through the new storm sewer system. Cost estimates will then be prepared for the options they present. This project will be the first to use the City's new Stormwater Utility Funds to relieve storm drainage problems that have plagued this area for many years. The Stormwater fees began on October 1, 2014. The first bills went out on November 10, 2014. The utility is projected to receive $1.078 million in 2015. It is expected that just under$90,000 will be received by the end of this year. SCHEDULE: Chastain& Associates is currently finalizing the Baltimore Road Reconstruction preliminary design for Macon County and is expecting to move into the final design phase by spring 2015. City staff currently plans to propose a final design agreement with Chastain in spring 2015 for the City's portion of the storm sewer design. Construction of the roadway and drainage improvements is expected to begin in 2016. Page 12
