Also, please include the off -site flows in the calculations that enter the site near the northwest corner of the site. 93 Issue Contact: Wes Lamarque 20. Since the Siena PUD did not anticipate flows entering their site from this project, all the flows at design points I and J need to be captured. Please provide larger (or more efficient) inlets at this location or create a sump in the street to allow all the flows to be captured. 94 Issue Contact: Wes Lamarque SWMM Comments 1. Please ensure a professional engineer signs and stamps the cover letter for the report. 95 Issue Contact.

Please provide details for all drainage facilities in the plans. 12 of 17 75 ►FV 77 78 79 M Issue Contact. Wes Lamarque 2. The outfalls from this site into the adjacent park are most likely not acceptable by the Parks and Recreation Department. Please contact them to discuss the outfall location and the possibility of piping these flows. As mentioned in the report, the possibility of expanding the park pond should also be discussed with them. Another possibility would be to outfall the site into the existing outfall storm sewer for Lory Ann Estates. Issue Contact. Wes Lamarque 3. Please provide written explanations in the text or the appendices of what changes have been made (if any) to the SWMM and HEC-2 models in the report. If either of these models have been modified, please provide documentation on what changes have been made. Also, please include a revised SWMM map and schematic and HEC-2 cross-section map. Also, as mentioned in the e-mail from Sue Paquette, the spillway design will need to be incorporated in the UNET model to determine the spillway's effect on the system as a whole and prove you are not creating a problem further upstream or downstream. Issue Contact. Wes Lamarque 4. Please include a discussion of water quality in the beginning of the report. Discuss why the southern portion of the site is not being detained and provide valid reasoning why a water quality variance should be granted for this portion of the site; if one is requested. Calculations for the water quality release rate and a detail of the water quality release structure are required. Detention volume for water quantity could be provided in the Overland Park ponds if they were enlarged. This would require an easement from the Parks Department. Water quality extended detention may be mitigated by the existing wetlands in the Park. Issue Contact. Wes Lamarque 5. It appears that there will be grading that occurs over the existing channel. The tie-ins for this portion of the grading will need to be more clearly defined. If a retaining wall needs to be installed here please include the top and bottom of wall elevations. Please include a detail of the box and invert elevations at the crossing. Issue Contact: Wes Lamarque 6. Please include a section in the report for signed copies of all easements (grading) obtained. Please also include a copy of the approval letter from the ditch company stating they are ok with ditch modification. Issue Contact: Wes Lamarque 7.

Electric facilities need to be shown on the utility plan. The developer's reply to previous comments (their reply #6) states "electric facilities and easements have been incorporated on the utility plans." A utility plan was not included in this review set, however the electric facilities could not be on it because L&P hasn't designed the system. The developer needs to contact L&P engineering to initiate the design. There is a $50.00 per lot deposit required before the electric system is designed. This deposit will be credited to the electric developoment charges if the final plan doesn't require a re -design of the electric system. 2. Streetlights need to be shown on the landscape plan & street tree locations adjusted to a minimum of 40 ft. from the lights. The streetlight plan will be includes as a part of the preliminary electric design (see #1 above). 9of17 63 64 65 67 .• Issue Contact: Sheri Wamhoff Utility plans - Pleasant Valley Road What type of curb exists on the property to the west?
