Z <br /> City of Eugene <br /> Public Works Engineering <br /> i <br /> 858 Pearl Street <br /> Eugene, OR 97401 <br /> Re: Mallard Lake Estates First Addition <br /> Dear Ginger, <br /> Some changes have been made to this project. On May 11, 2004 we asked the City of <br /> Eugene Parks and Open Space Department (Jonny Medlin and Andrea Rifler) if the city was <br /> interested in helping to pay for Jessen Street being constructed as a full street, and they said yes. So, <br /> now you have a slightly different design with a full street section and an additional stormwater catch <br /> basin and curb inlets to help pickup the storm water runoff. Also, our office is going to help put <br /> together some agreement between the developer and the city for the additional cost associated with <br /> constructing Jessen Street. <br /> To help you out, the areas which have been changed on the construction drawings are: <br /> 1. Full Street with curb & gutter along Jessen Street. <br /> 2. No curb & gutter from Devos to Sta. 2 +05 on the south side of the street <br /> 3. New drywell manhole with one catch basin and one curb inlet at sta. 0 +21.50 <br /> 4. One new curb inlet at sta. 9 +52.40 <br /> 5. Paving will not go south on Devos, paving will only be to the intersection of Jessen & <br /> Devos. <br /> 6. New storm sewer calculations. <br /> 7. Adjusted street grades for proper drainage to storm sewer. <br /> • <br /> Finally, I have not provided any calculations for the storm sewer drywell manhole at sta. <br /> 0 +21.50. This area always has a water puddle during rain storms and it is hoped that the design <br /> presented will help alleviate the problem. Also, this design will enable future drainage design to the <br /> ponds on the north side of Jessen. <br /> Hopefully, this covers most of the changes. Finally, I am sending you a copy of the memo I sent to <br /> the Parks & Open Space Department. Also, notice how I forgot to include sidewalks in the cost to <br /> the city. Sidewalks will have to be included as an extra. <br /> Sincerely, <br /> V' l w a�-- <br /> Matthew M. Warren <br /> CIVIL /ENVIROA'.MENTAL ENGINEERING SURVEYING <br /> P.O. BOX 2527 El GENE.
