CR 99-38 Services Agreement - Storm Water Improvements 2nd St N "\ y \ 0 CJ '" ~ -s- '" February 11, 1999 0 P K \ "" Council Report 99-038 e Approve Engineering Services Agreement - Storm Water Improvements, 2nd Street North and Alley (Problem Area 5) Proposed Action. Staff recommends adoption of the following motion: Move that Council authorize the City Manaoer to enter into an aoreement with RCM & Associates for enoineerino services related to storm sewer improvements. Area 5. City Proiect 98-16. Overview. Storm water problem area 5 includes the local low area near the midpoint of the alley between 8th and 9th Avenues North and 2nd and 3rd Streets North. This area has a history of flooding and City Council included it in the action plan adopted in November 1997 to address storm drainage problem areas. Staff initially was hopeful that an analysis of the 6th Avenue storm sewer improvements would yield some benefit to this area, as well. Unfortunately, drainage from this area is not expected to improve with the 6th Avenue project. A detailed feasibility report with improvement alternatives for Area 5 was completed in September, 1998. The . feasibility report was presented to the residents at a Sept 3, 1998 public meeting. The residents were in favor of the recommended a\temat\\le. ReM 'nas stated that this improvement is not contrary to improvements to be recommended in the revised stormwater management plan. The city's stormwater consultant (RCM & Associates) is currently updating the city-wide stormwater management plan. Staff now requested approval to complete design so that construction may begin in the Spring. Primary Issues to Consider. . Description of Proposed Improvement . Selection of Consulting Engineer .

Council Report 99-038 Page 2 Analvsis of Issues . Description of Proposed Improvement The recommended alternative is to reconstruct the alley from the low point catch basins south to 2nd Street North and reconstruct 2nd Street North from ih Avenue to 9th Avenue. This will allow the alley to overflow onto 2nd Street at a lower elevation thus decreasing the ponding at the low point to no more than 6 - 8 inches. The inlet capacity will be increased to match the available pipe capacity. . Selection of Consulting Engineer RCM has already performed significant work in preparing the detailed feasibility report and design survey of the area. It is in the city's best interest to allow them to continue with the design plans and specifications. . Engineering Services Costs e RCM's proposal is to complete design work at a cost not to exceed $18,600. Construction administration fees will be negotiated separately upon completion of design. .

These improvements are proposed for the alley between 8th and 9th Avenue North immediately north of 2nd Street North and the associated street improvements on 2nd Street North between 7th Avenue and 9th Avenue. I rieke have attached an itemized breakdown of the expected costs for this work for your review. carroll muller ~SS?Ciates, inc. I have reviewed the information available and it is my opinion that the construction cost n~neers will be in the range of$175,000 to $200,000. There are a number of variables that could arc itects land sUlVeyors impact the cost such as depth of the storm sewer, condition of the sanitary sewer and equal oppol1unity condition and depth of the waterrnain. employer You can expect to have the 30% plans completed and ready for your review approximately 30 days after we receive a notice to proceed. The final plans and specifications will be completed approximately 15 days after we receive your comments regarding the 30% review. We propose to perform this work based on our hourly rate schedule, excluding construction administration, with a cap not to exceed $18,600 without your. prior approvaL A copy of our most recent hourly rate schedule is attached. Thank you for the opportunity to submit this proposal. We look forward to working with you on this project. Sincerely, RIEKE CARROLL MULLER ASSOCIATES, INe. CLJ . DC"k 10901 red circle dr. David e.

Phone: 612-939-1382 · Yax: 612-939-1381 September 3D, 1998 Dear Resident/Owner: The purpose of this letter is to provide updated information on storm water flooding "Area 5" and has been sent to all residents betlNeen 8th and 9th Avenues North and 2nd and 3rd Streets North. The city is taking action to eliminate the flooding problem in the alley and surrounding garages and yards. A city consultant has completed a feasibility report addressing the storm water flooding problem. The results of this report were discussed with residents who attended a September 3rd public information meeting. City Council then accepted the report and its recommendations at the September 15th City Council meeting. The feasibility report is enclosed for your information. The report includes an analysis of the existing drainage problem, a description of the recommended improvement project (Alternatives 1 and 2), estimated project cost and a proposed schedule. . City staff is proceeding in order to be ready to construct the improvement project next spring/summer. This fall, the city's engineering consultant will-be completing a design survey of the project area. This will be followed by project design in January - March, 1999. Finally, we anticipate City Council project approval in March '99 and construction in May-June'99. I would anticipate another public informational meeting during the project design phase followed by notification prior to construction start. If you have any questions or comments on the enclosed report or proposed I improvement project please call Jim Gessele, Engineering Supervisor at 935-8474 or myself at 939-1338. rr , Steven J.
