Ms. Katie Larsen April 06, 2016 Page 4 K:\02029-820\Admin\Docs\20160516 Engineering Review Lino Lakes-Mattamy.docx 10. The updated Noise Study, dated March 3rd 2016 was reviewed. The following comments should be addressed by the applicant: a. The site that was shown in the wrong location on Figures 1.1, 2.1 and 2.2 has been revised with the updated study memo. WATER SYSTEM 1. Note the attached water system memo dated April 5, 2016 (Attachment 2) that outlines the system needs based on the proposed development and the City’s comprehensive plan. 2. A 12 inch diameter watermain shall be looped on the northwest end of the plat. 3. The 16 inch diameter watermain shall be looped through the park. 4. Hydrants shall be installed next to the stormwater re-use system pumps. 5. Fire hydrant locations shall be reviewed by the City’s Fire Division staff. 300 foot maximum hydrant spacing. 6. A hydrant shall be installed on Street F between Street G and Street C. 7. All hydrant leads shall be a minimum of 6 inches in diameter. 8. The dual 8 inch lines in Street U shall be separated as much as possible (opposite sides of the road). 9. The 16 inch trunk watermain loop to the east shall be installed under I35E when the adjacent phase of the development is constructed. This will be a City improvement project. Show on the plat documents as such. 10. A 12 inch watermain stub is to be extended under CSAH 54 at 77th Street for future looping. 11. An 8 inch water stub to the south shall be installed at the Townhomes (at the trail location). This will provide a future loop to the south parcel. SANITARY SEWER SYSTEM 1. An 18-inch sanitary line shall be extended along Street A to CSAH 54 and along Street B to the roundabout, at maximum depth. An 8-inch sanitary line shall be stubbed under CSAH 54 to the west. 2. Please provide either sanitary system profiles or all pipe lengths and slopes so that invert elevations can be verified. 3. With the second phase of the development, assuming phase one has approximately 100 residential connections, the lift station No. 8 pump upgrade will need to be completed. This will be a City improvement project. TRANSPORTATION 1. The traffic study, dated February 13, 2015 and latest technical memo dated March 25, 2016 prepared by Spack Consulting still needs to be refined as detailed below. However, we generally concur that the development can be accommodated with the roadway system proposed. 2. The Watermark development access spacing was reviewed in coordination with Anoka County staff during the concept plan review stage. The access spacing is also in conformance with those outlined in the AUAR completed for this area. The access was
