Shira, P.E., City Engineer/Utilities Director SUBJECT: Hackney Prairie Road Final Changes On November 17, 1998 the City Commission authorized execution of a tri-party agreement between Imperial Partnership, Prairie lake Joint Venture and the City of Ocoee for certain improvements to Hackney Prairie Road. These improvements included roadway widening, sanitary sewer, water and reclaimed water facilities. During the course of the work, several issues arose which had to be addressed an a timely manner, some of which resulted in additional cost. Those changes are detailed below along with a justification for their field approval and the dollar amount associated with each. • A deep sanitary sewer line was installed along the north side of Hackney Prairie Road to serve Prairie Lake subdivision, Remington Oaks subdivision, and undeveloped property east of Remington Oaks. To limit the depth of lateral lines serving Prairie lake subdivision, and thereby limit our maintenance cost, we installed two drop manholes so that the lateral lines would be at a shallower grade. The cost for this change is $4,715.00. I recommend that the City Commission authorize a transfer from Wastewater Reserve for Contingency to cover this cost. • The widening of Hackney Prairie Road to three lanes in the vicinity of the future park required that several existing drainage structures be reconstructed. We also added a storm sewer manhole to allow maintenance crews better access to the emergency outfall end of the system. In addition, we agreed to pay the developer$450.00 to regrade the existing pond while he was in the area, to restore its original contours. This pond had been badly eroded by four wheeler traffic over the years, since it was in a very low traffic, out of the way location. The cost for this change is $3,840.00. I recommend that the City Commission authorize this amount to be paid from the stormwater fund. • The contract document did not include a line item for chlorinating the reclaimed water piping along Hackney Prairie Road. This was an oversight, and we asked for and received a proposal for the work from this project's contractor. The amount requested was in line with similar work we have had performed by other contractors, and we authorized him to proceed so the lines could be put into use. For now,the reclaimed lines in this area will be connected to the potable water system, but the potable system is protected by a backflow preventer. When the reclaimed water system is completed,this connection to the potable system will be removed. In this way,houses being built now will only need to make one connection to a water source, and won't have to reconnect to another pipe when reclaimed water is available. The cost for this change is $1,140.00. I recommend that the City Commission authorize this amount to be paid from the 1997 utility bond issue proceeds. • A large amount of the existing sidewalk along Hackney Prairie Road had been damaged by vehicles in the years since the road was built. We didn't want to open a brand new road leading to two new subdivisions, and have a broken, damaged sidewalk for much of its length. We authorized the contractor to remove the damaged sidewalk and replace it. The cost for this change is $6,990.00. • When the original plans for Hackney Prairie Road were drawn,the road was an Orange County road, and the plans were drawn to their standards as a semi-rural road. This is the design that was used to construct the portion of Hackney Prairie that has been in place for several years now. The new section of Hackney Prairie Road was designed as an urban road with a thicker asphalt layer to handle the anticipated traffic from the existing and future subdivisions. To make the existing and new sections of Hackney Prairie Road have the same structural strength, we added an asphalt overlay to the existing section at the same time the new section was paved. The cost for this change is $2,439.75. We also had to remove and replace the end of the existing road due to damage from vehicles running off the end over the past few years. This work was required to make the old pavement transition smoothly to the new pavement section. The cost for this change is $3,034.50. The total cost for the pavement changes is $5,474.25. I recommend that the City Commission authorize the cost for the paving and sidewalk work, in the total amount of$12,464.25 be paid from the Traffic Impact Fee fund. The total amount of all of the above changes is $22,159.25 which represents 7.7% of the originally agreed-upon amount in the tri-party agreement. Of this amount, $4,715.00 or 1.64% is attributable to the sanitary sewer system changes, $3,390.00 or 1.18% is attributable to the storm sewer system changes, $2,439.75 or 0.85%is attributable to the pavement overlay, and$1,140.00 or 0.40% is attributable to the reclaimed water system changes. The remaining $10,474.50 or 3.64% is attributable to repairing or replacing road and sidewalk facilities damaged by unauthorized traffic over the past years. The changes initiated by the city therefore amount to 4.07% of the originally agreed upon amount. I recommend that the City Commission authorize that payment for the above changes be made as described, and authorize fund transfers as appropriate.
