HomeMy WebLinkAbout#13 - Cimarron Grading PermitSTAFF REPORT DATE: 4/6/2021 Regular Agenda TO: Mayor and City Council ITEM: Cimarron Manufactured Home Community Grading Permit SUBMITTED BY: Ben Prchal, City Planner REVIEWED BY: Ken Roberts, Planning Director Jack Griffin, City Engineer SUMMARY AND ACTION REQUESTED: The City Council is being asked to consider a grading permit request from Kimley-Horn for the Cimarron Community Manufactured Home Park to remove sediment from their Rapid Infiltration Basins (RIBs). The applicant is proposing to excavate over 400 cubic yards of material, triggering the need for a public hearing, and resulting in the need for City Council approval. Furthermore the project also is within the shoreland area for Rose Lake and any movement of over 50 cubic yards of earth within the shoreland district requires a grading permit. Grading also is subject to meeting City standards for erosion control and the standards of the Valley Branch Watershed District. GENERAL INFORMATION Applicant: Kimley-Horn and Associates Inc. Property Owner: MHC Cimarron LLC, PO BOX 6115, Chicago Il, 60606. Location: Section 36 Township 029 Range 021 SW1/4-NE1/4 Request: Grading Permit Approval Grading Project Area: +/-3.5 acres Deadline for Action: Application Complete – 3/2/21 60 Day Deadline – 5/1/2021 Extension Letter Mailed – No 120 Day Deadline – NA Applicable Code: 151.017 Excavation and Grading Permits 150.270 Storm Water, Erosion, and Sediment Control 154.800 Shoreland Management Overlay District 154.103 Permits, Certificates and Licenses Article III – Environmental Performance Standards REQUEST DETAILS Kimley Horn is requesting a grading permit to excavate sediment and additional vegetative material that has accumulated within the Cimarron community Rapid Infiltration Basins (RIBs). The basins are designed to be a permeable basin which will treat and disperse wastewater. This basin acts as the final cleaning stage of the in the private wastewater cleaning process. With these basins acting as the final infiltration of water from the retention ponds adjacent to Rose Lake it is important that they stay “clear” of debris so they can operate to their best potential. The clogged basins has resulted in slow infiltration rates which has resulted in slower cycling of wastewater. To summarize the project, they will be removing 12 inches of material from the bottom of the north RIB and replace it with 12 inches of clean sand while simultaneously removing 12 inches of material form the south RIB and adding in 3.5 ft. of clean sand material. A clay liner will also be installed around the rim of the basins so that the water will properly permeate. PLANNING AND ZONING ISSUES VBWD Permit. A Valley Branch Watershed District permit will be required prior to any grading work being done. The grading permit will be conditioned on VBWD providing approval. Shoreland. With the grading taking place within the shoreland area of Rose Lake. The proposed project has been sent to the DNR for review. 2 Engineering Review. The engineering review for the Grading and Erosion Control Plan is very important as the majority of the project is related to engineering standards. The City Engineer has reviewed the project plans and their comments have been attached (Memo dated 3-29-2021). Public Comment. City Staff did receive some public comments from the neighboring property to the East. The neighbor is in favor of the correction if the plan is able to fix the issue of water seeping onto their land. However, if the maintenance of the RIBS does not fix the issue of seeping water they would like corrective action taken to connect the neighborhood to City Sewer. In response to this concern, the applicant has reached out to Staff to explain that the maintenance on the RIBs is intended to improve the situation. DRAFT CONDITIONS OF APPROVAL: Staff is recommending approval of the grading permit for Kimley-Horn to conduct grading activities within the RIB’s in the Cimarron Manufactured Home Community with the following conditions: 1. That a permit is obtained from the Valley Branch Watershed District. If a permit is not required a statement from the Watershed District stating that it does not meet the threshold to require a permit. 2. That a MPCA NPDES Permit are obtained and that all conditions of the permits are complied with. 3. That the conditions outlined in the City Engineer’s Memo dated 3-29-2021 be updated or incorporated prior to beginning work. 4. That site access to the property be limited to 10th Street North between Layton Ave. and Leeward Ave. 5. That vegetative and tree protective fencing be installed prior to grading and that the locations be staked and field inspected by the City prior to installation. 6. That construction hours be updated and limited to 7:00 AM to 7:00 PM Monday – Friday and 8:00 AM to 6:00 PM on Saturdays with no construction or grading activity on Sundays. DRAFT FINDINGS Staff is recommending the following findings with regards to the proposed grading project: 1. That the project is intended to maintain and improve the function of the Rapid Infiltration Basin(s) (RIBS) within the Cimarron Manufactured Home Park. 2. That the project will consist of excavation and grading of 2,655 cubic yards of material specifically to improve water mitigation within the RIBS. 3. That grading will be fully conducted on site with no off site impacts beyond normal maintenance activities. 4. That it is expected that the project will need to remove trees for implementation and completion of the project. 5. That the grading and erosion control plans will be updated and approved by the City Engineer so the operations on the site will comply with the City’s Storm Water, Erosion, and Sediment Control, and Tree Preservation ordinances and design standards. RECOMENDATION: Staff recommends that the City Council approve the grading permit with the conditions of approval as listed in the Staff report. Suggested motion: “Motion to approve Resolution 2021-035 which grants approval of the grading permit to remove sediment and repair the RIB(S) with the Cimarron Manufactured Home Park with conditions of approval as presented.” ATTACHMENTS: 1.

Scope of work is to subcut 12” from the bottom of each RIB and replace with 12” of clean sand in the North RIB and 3.5’ of clean sand in the South RIB. Clay impermeable layers will be installed on the south ends of both RIBS to help with migrating water. Erosion control measures will be installed prior to start of construction and be removed after restoration and turf establishment. Rapid Infiltration basins are permeable basins, designed and operated to treat and disperse wastewater. The Cimarron RIB’s are the final cleaning stage of the wastewater treatment process. Water is pumped up from the settling ponds, adjacent Rose Lake, and drained into one of two RIB’s. Rapid infiltration of wastewater is based on a relatively high rate of infiltration into the soil followed by rapid percolation, either vertically or laterally away. The reason for this project is due to clogging that has occurred over years of settlement and weed/tree growth in the bottom of the RIB’s that has slowed infiltration rates. This project will improve the RIB percolation rates and disperse water quicker between cycles. The project is currently into the MPCA for review, so a Contractor and schedule hasn’t been developed yet. Once approved, a Contractor will be selected and hopefully be able to complete the work in April with a 3 to 4-week construction timeline, barring weather conditions. Work schedule would be Monday – Saturday, from 7am to 7pm. The attached PDF shows the haul route through the Park out to 10th Street. Once awarded the GC will have to provide us more info on where the fill will be coming from and his exact haul route to the site. Please let me know if you need anything else for review and approval of this permit. Sincerely, Alan Catchpool, P.E.

Lake Elmo, MN 55042 Dear City of Lake Elmo, We are the Screaton family.Since 1989,we have owned and farmed the 40-acre parcel directly to the east of the Rapid Infiltration Basins (“RIBs”).The RIBs are located within twenty feet of our parcel.Starting in 2017,wastewater from the RIBs has leaked onto our land,which makes farming the parcel very difficult and impedes future development.In 2017,we notified Cimarron about the leak.Cimarron later told us they had contacted the relevant authorities and were working to fix it. We want a permanent solution to this problem and are satisfied if the Kimley-Horn plan fixes it. However,if the leak persists,we want a commitment that Cimarron will hook up to the sewer as outlined in the 2040 Lake Elmo Comprehensive Plan,Chapter 9, Wastewater: The 2020 Staging Plan includes the extension of a second trunk sewer from the MCES Cottage Grove Ravine Meter Station to serve the portions of the Southeast Planning MUSA from Lake Elmo Avenue to Manning Avenue.In addition to serving new development in this area,service will be extended to the existing Cimarron manufactured home park consisting of approximately 510 units.Cimarron owns and operates a private sewer collection and wastewater treatment system.A new lift station will likely be required to connect to the City sanitary sewer system.This service area also includes the future connection to the existing Oakland Junior High School to replace an existing on-site wastewater facility. Page 320, 9-3. The existing units in the Cimarron manufactured home park will be served by regional sewer between 2030 and 2040 unless environmental threats require a more immediate connection. Page 324, 9-7. (emphasis added). We are concerned this wastewater leak could qualify as an environmental threat warranting a more immediate connection. Attached is a picture showing the proximity of our land to the RIBs. Thank you for the opportunity to provide comment. Sincerely, The Screaton Family
