  <br />through the site from east to west. The site also contains several wetlands. The Nature’s <br />Refuge development proposes a storm sewer and ponding system. The system shall meet the <br />City’s and Rice Creek Watershed District’s (RCWD) Stormwater Management <br />requirements. The total proposed impervious surface is 7.8 acres. They are proposing that <br />the impervious areas be managed through storm water ponds, infiltration basins and <br />wetlands and discharging to ACD 10-22-32. <br />  <br />Basin <br />  <br />NWL <br />  <br />HWL <br />  <br />Pond 100 <br />  <br />902.5 <br />  <br />905.2 <br />  <br />Pond 200 <br />  <br />901.5 <br />  <br />902.6 <br />  <br />Pond 300 <br />  <br />902.0 Confirm <br />  <br />902.5 <br />  <br />Pond 400 <br />  <br />901.8 <br />  <br />902.7 <br />  <br />Basin 10 <br />  <br />N/A <br />  <br />907.3 <br />  <br />Wetland C <br />  <br />902.0 <br />  <br />903.1 <br />  <br />Per the submitted modeling the rate control for the site does not increase. The majority of <br />the discharge leaving the site is through ACD 10-22-32. <br />  <br />Comments: <br />  <br />1. RCWD is the ditch authority for ACD 10-22-32 and is responsible for the maintenance, <br />function and capacity of the ditch. The City of Lino Lakes would be responsible for <br />Pond 200 maintenance and function. The ditch, and its associated rights, extend east <br />and shall not be routed through the pond. The easement will extend around the north end <br />of the pond to provide RCWD with the access needed. This has been discussed with the <br />watershed. Applicant shall address water quality calculations, and confirm <br />whether Pond 200 is necessary for water quality treatment for the impervious <br />surface increase. If the pond is not necessary to meet water quality treatment, then <br />similar to Pond 300, Pond 200 is recommended to be private and be maintained by <br />the Home Owners Association. If Pond 200 is necessary for water quality <br />treatment, the applicant shall work with the City as well as the RCWD Ditch <br />Authority. Pond 200 should be 2 cells separating ACD 10-22-32 into one basin, and <br />the City Pond into a second basin as needed for water quality. <br />Pond 200 is not necessary to meet NURP requirements. <br />Pond 200 and Pond 300 are not necessary to meet NURP requirements and should <br />be identified as something other than a pond (lake, basin, etc.) and are also <br />recommended to be maintained by the Homeowners Association. <br />2. Pond 300 is not considered a stormwater pond. It doesn’t meet the requirements for <br />water quality treatment due to the depth. It was not included as part of the water quality <br />calculations. It is recommended that this borrow area should be private and <br />maintained by the Home Owners Association.. Comment Noted <br />This shall be called out in the agreement and provided by the developer. <br />3. The applicant needs to adjust the location of the outlet control structures such that City <br />can access and maintain. Specific to Pond 200. Access is provided to outlet control <br />structures. <br />3A. Applicant to confirm that RCWD Ditch Authority to maintain outlets and
