~ 2007 PMP 2/8/2007 Page 2 Katie Lane and Katie Court Several residents raised concerns at the public hearing about the need for improvements to these streets at this time, as well as the uncertainty of the potential development at the end of Katie Lane. Staff met with the owner/developer of the property, and he has indicated that he is interested in moving forward with the third phase of the development at this time. No official preliminary plat submittal has been made to date, however the developer indicated a submittal would be made this year, and construction is anticipated to begin once all approvals have been received. In light of the more definitive information provided by the developer at this time, staff recommends deleting Katie Lane and Katie Court from the 2007 PMP. Staff will continue to work with the developer to determine the timing of maintenance for the streets. This may include a seal coat, or delaying the mill and overlay project until it can be completed in conjunction with or following the construction of the development. Utilitv Improvements Sanitarv Sewer Repair of approximately 30' of sanitary sewer main line is proposed for Briarknoll Drive. Storm Sewer In an effort to improve water quality to Karth Lake, staff recommends the reconstruction of the catch basins on Karth Lake Circle to be open-bottomed structures that will allow storm runoff to infiltrate and receive some pre-treatment prior to discharging into the lake. Watermain The replacement of a gate valve is proposed on Brighton Way. At the public hearing, staff recommended the replacement of the watermain under Connelly Avenue. This is due to a recent watermain break on Connelly Avenue. The Public Works crew expressed concern about the condition of the existing pipe, and feel that it is appropriate to replace the main prior to rehabilitating the pavement. FINANCIAL IMPLICATIONS The revised estimated total project cost for the improvements is $814,406, including 15% for engineering fees. Consistent with the Assessment policy, we have included an additional 32% overhead for the street improvements, which was used to calculate preliminary assessment rates. The City's portion of the project costs are currently budgeted from the General Capital Fund and Utility Enterprise Funds (sanitary sewer, surface water and watermain funds). The following shows a breakdown and comparison of budgeted amounts and a revised engineer's estimate based on the proposed final plans.
