will be sized to address all impervious surfaces within the developable area including the public improvements and all individual site development within the study area. • Park Fill is the estimated cost to grade the proposed City park parcel, fill the site to an elevation equal to the adjacent streets, place 4 inches of topsoil and seed and mulch the entire site. The estimated project cost to fill the site, topsoil, seed, and hydromulch is approximately $231,000. Alternatives Analysis An analysis was performed to determine the benefits and costs associated with construction of a bioretention basin in the median area of Ramsey Parkway. The benefits associated with a bio-retention basin include: water quality improvements, potential traffic calming and creation of a landscaping feature within this area of The COR. Costs associated with creating the bioretention basin are included in the roadway portions of Ramsey Parkway (Segments A-1, A-2, and A-3). VIII. COST ALLOCATION ALTERNATIVES The costs, or a portion of the costs, of the improvements are typically allocated back to adjacent properties through the use of assessments, fees and other methods. The costs are typically allocated in a way that is equitable to the properties benefitting from the improvements. Public improvements that will become City owned and maintained are typically constructed through a public process, while secondary improvements are constructed by the property owner. For our analysis, we assumed the following items would be constructed through the public process: • Roadways, including storm water conveyance systems, • Water System Facilities, • Sanitary Sewer Facilities, • Trails, • Street Lighting, and • City Parks While the street lights will most likely be installed by a private utility and the trails could potentially be constructed by the property owner, we have included these items as public improvements. Other improvements were considered secondary and are typically the property owner's responsibility: • Sanitary Sewer Service Extensions, • Water Service Extensions, • Natural Gas Lines to Buildings, • Telephone Service to Buildings, • Electric Service to Buildings, • Site Grading, • Site Landscaping, • Site Storm Water Conveyance, and Easement Dedication. These types of improvements are typically inspected by the City for conformity with applicable codes and standards, but are constructed by the property owner. Prepared by: Bolton & Menk, Inc.
