future. Storm Water These streets currently do not have storm sewer; there is minimal storm sewer north of the project limits along Ridgewood Road into the wetland near the tennis courts. We will be installing curb and gutter as a part of the street reconstruction project, as well as storm sewer pipe and catch basins, where needed, to accommodate storm water. This road is located within the Rice Creek Watershed District. Their rules for road projects require that this project provide volume control for the storm water runoff. This can be accomplished through the construction of rain gardens and/or infiltration trenches within the street boulevards. The rain gardens in the boulevards would be maintained by the property owners. We are working with property owners on identifYing locations for these basins. If we are unable to find residents that support the construction of a rain garden in their boulevard, we will construct infiltration trenches to meet the Rice Creek infiltration requirements. ESTIMATED COSTS/PROPOSED FUNDING Proposed construction costs for the 2008 PMP Improvement Project (including bituminous street, stonn sewer, sanitary sewer, watermain, and turf restoration) are itemized in the tables located in the appendix and are summarized below. The City's assessment policy states that estimated construction costs should include 37% for overhead costs and a contingency factor. Overhead costs include legal, engineering, administrative and fiscal costs. The estimated costs for street improvements listed below include 32% for overhead costs, since the City of Roseville's proposal for the project was based on 15% for engineering fces, not 20%, as is listed in the policy. Utility improvements are not assessed; therefore, the cost estimates for utility work include only an additional 15% for engineering fees. These cost estimates are based upon 2007 public construction costs. Since we have no control over the cost oflabor, materials, competitive bidding process, weather conditions and other factors affecting the cost of construction, all cost estimates are opinions for general information and no warranty or guarantee as to the accuracy of construction cost estimates is made. 14
