Clty of Orono Page 4 � Surlace Water Management Plan January 8,2009 Proposed Compensation We propose a fee of$18,400 for the work described above. Miscellaneous expenses would be billed as encountered and are estimated at$500. The proposed fee includes printing reports as described above. If - additional reports are desired,we would gladly print these for the City on a time and materials basis. We could provide a cost quote for additional reports if requested. Hourly 7ask: Development of a Phosphorus Reduction Plan As required by Minnehaha Creek Watershed District, Orano must develop a plan to reduce phosphorus in its surface water discharge by 230 Ibs/yr over the 10-year span covered by the updated SWMP. This effort entails identifying potential projects and development controls and quantifying their benefit toward phosphorus reduction. We will also review projects since 2000 and apply phosphorus reduction obtained from these to the 230 pound target identified by the watershed. On lanuary 7, 2009 we met with Minnehaha Creek Watershed Distritt to discuss the autline of the _ phosphorus reduction plan. We determined that Orono's best course of action entails a collaborative and iterative process with the watershed. As we discussed, Orono will develop its initial draft through the - combined efforts of Orono and Bonestroo staff. Subsequent revision to that draft due to watershed tomments may also involve the combined efforts of Orono and Bonestroo staff. The Phosphorus Reduction Plan will be a separate section of the SWMP but will be integrated with other applicable sections including the Assessment, Goals and Policies,and Implementation Sections. We propose that the Phosphorus Reduction Plan rely on modeling already completed by the watershed and not on new modeling performed by Orono, � The level of effort needed to prepare a Phosphorus Reduction Plan is somewhat uncertain. This consideratian and the fact that City and Watershed staff resaurces will be used, leads us'to recommend hourly compensation for this specific work item. Potential Supplernental Services As we discussed at our meeting, Orono might benefit by having a cohesive and single source of stormwater design guidance. A level one design guide takes the form of a several page document outlining: t, Submittal requirements Z. Design requirements for stormwater infrastructure 3. Performance measures(valume,water quality,and rate control)and how these are evaluated The design guide complements the SWMP by providing more detail on specific elements of the stormwater system and by outlining how different parts of the system are analyzed, A level two design guide adds more introductory discussivn on design and modeling theory—further cementing a consistent approach to design and analysis within Orono's stormwater system. We have an example of a level one and level two design guide that we could provide for your review. We could prepare Orono's de5ign guidance for the following compensation: • Level 1: $2,500 • Level 2; $3,60�
