# September 19, 2002 Mr. Ron Moorse, Administrator Oty of Orono 2750 Kelley Parkway, PO Box 66 Crystal Bay, MN 55323-0066 Re: Additional Budget for the Orono Surface Water Management Plan Bonestroo Project # 198-98*063 Dear Ron: As you are aware, the development of Orono's Surface Water Management Plan (SWMP) has exceeded the original time and budget In this letter we have prepared a description of additional services associated with runoff management planning in Orono, as well as the amount of additional costs associated with the SWMP. Also, Mike Gaffron and 1 have recently completed work to resolve issues for final approval from Minnehaha Creek Watershed District (MCWD). From the submittal of the review draft to MCWD (May 2001) to the present, we have included hours spent on this project under the "general” billing number, with detailed descriptions. Descriotion of Additional Services Because this SWMP has evolved over a six-year period, it has effectively had two lives. The first was the draft approved by staff in 1997. Subsequent edits, updates, and changes to the SWMP have resulted in a better, more implementation-oriented runoff management tool. It now has detailed schedules, priorities, cost estimates, and strategies to approach a variety of surface water issues. This means that Orono will realize immediate, tangible benefits from its investment in runoff management. Some of these additional services have already been put to work, while others will happen as the SWMP is implemented. Following is a brief d^ription of changes and updates to the SWMP since the 1997 draft. ♦ GIS Maps and Databases The originally approved GIS for system mapping was a UNIX-based system. Over the life of the project, GIS has evolved into a PC-based sy^em. In order to be compatible with Orono's PC-based system and to be able to keep up with current GIS technology, the entire data set for producing maps and associated information was converted. ♦ Work Flow Interruption There have been periods of time that work on the SWMP stopped. The lengths of time, source, and reasons for interruption have varied. When the project resumed after an extended period of time, "getting back up to speed ” resulted in additional hours. Consequently, some parts of the SWMP had to be revised to reflect new information. ♦ Trunk Fee/Stormwater Utility The research, compilation of information, and rate determination for the "trunk fee” and the "stormwater utility” were done coincidental to SWMP development The method used to determine
