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 alternate cost analysis was performed to determine the difference in cost if a bioretention basin was constructed along the median in Ramsey Parkway. The bio-retention basin is not required to meet water quality volume requirements, but instead to create a native plantings and landscaping feature. There is little difference in costs associated with creating a bioretention basin along the median. The primary difference relates to whether the median area is raised or depressed. Costs associated with plantings, curb cuts, etc. are not considered significant. 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.
