Resolution 2011-054. � EN HILLS MEMORANDUM DATE: November 14, 2011 TO: Honorable Mayor and City Councilmembers Patrick HIaers, City Administrator ,A,� ��n- FROM: Terry Maurer, Public Works Director l j� SUSJECT: US 10/Hwy 96 Municipal Consent Resolution Back�round Ramsey County is proposing an interchange improvement to the intersection of US 10 and Hwy 96. Earlier this year the City was presented with a Mn/UOT staff approved layout and Municipal Consent was requested. A Public Hearing was held by the City Council on July 11, 2011. Also, this project was discussed with representatives of Ramsey County at work sessions on Apri125, 2011, August 15, 2011, and September 19, 2011. At the September 26, 2011 Council meeting Resolution 2011-048 was adopted disapproving the final layout of the US 10/Hwy 96 Improvement with four conditions. Those conditions were as follows: 1. Mn/DOT is currently undertaking an improvement to I-694 at TH51. This project will have the bridge over I-694 from Hamline Avenue to TH51 (Snelling Avenue) closed for most of the next two years. Mn/DOT is also planning to let a contract to widen the Lexington Avenue Bridge. Although this work will be completed under traffic, it will have an effect on the flow of traffic across the bridge. Therefore, to maintain some minimal mobility for local traffic to move north to south, Highway 96 shall not be closed in the same year that the Lexington Avenue Bridge widening is completed. 2. Ramsey County and/or Mn/DOT shall re-evaluate the noise analysis work completed for the southwest quadrant of US 10 and Highway 96 to determine if a different length noise wall and/or a different height noise wall would meet the criteria for cost effectiveness.

The Concrete Barrier Type F planned to be installed adjacent to Lakeshore Place as part of the improvement shall be increased in height to the tallest Type F barrier that can be slip-formed in this location. 4. Ramsey County shall make every effort short of utilizing eminent domain procedures to realign the west end of the noise wall on the north side of Highway 96 so it is in the appropriate location to facilitate a further extension with future highway improvements On October 21, 2011, staff received the attached response from Ramsey County to the City's four conditions. Attached to Ramsey County's letter is a copy of an October 10, 2011, letter from Peter Wasko, Mn/DOT Metro District Noise and Air Quality Supervisor, dealing with Condition #2. Also, attached is a memo from Chris Chromy regarding his review of Condition #2 responses from Mn/DOT. Basically, Ramsey County's responses to the City's four conditions are: 1. The US 10/Hwy 96 project will be constructed in 2013 so that Hwy 96 is not closed in the same year that Mn/DOT widens the Lexington Avenue Bridge. 2. A re-analysis of all the available noise data indicates that there is no length and/or height noise wall for the southwest quadrant that meets the cost effective criteria for inclusion of such noise wall in the project. 3. The barrier for Lakeshore Place has been increased to 63 inches in height (56 inches above ground level). 4. Ramsey County agrees with Condition #4 and will pursue accomplishing it. Based on these responses from Ramsey County, staff recommends granting Municipal Consent to the US 10/Hwy 96 Improvement. Attached is Resolution 2011-054 which approves the final layout for the improvement thereby granting municipal consent and rescinds Resolution 2011-048. Council Action Requested Adopt Resolution 2011-054 Approving the Final Layout of the US 10/Hwy 96 Improvement and rescinding Resolution 2011-048.

Highway 96 Arden Hills, MN 55112 CONDITIONS FOR MUNICIPAL CONSENT FOR RECONSTRUCTION OF THE RAMSEY COUNTY STATE AID HIGHWAY (CSAH) 96 / MINNESOTA TRUNK HIGHWAY (TH) 10 INTERSECTION Dear Mr. Klaers: At the September 26, 2011 Arden Hills City Council meeting, the Council passed Resolution No. 2011-048, disapproving municipal consent for the reconstruction of the CSAH 96lTH 10 intersection. This resolution listed four conditions to be met before municipal consent is granted. We believe that the conditions have now been met, as summarized below: ►i � 0 0 We applied for a sunset date extension that was approved by the Metropolitan Council Transportation Advisory Board's Funding and Programming Committee on October 20'h. This extension will allow the project letting to be moved to 2013, thus ensuring that Lexington Avenue and CSAH 96 will not be closed in the same year. The Minnesota Department of Transportation (MN/DOT) has re-analyzed the noise analyses that were done on TH 10 and concluded that no length or height wall will meet the threshold for cost reasonableness for residences in the southwest quadrant of CSAFi 96 and TH 10. A copy of the MN/DOT letter is enclosed. MN/DOT designers have confirmed that the retaining wall between lakeshore Place and Old Highway 10 (CSAH 76) can support the higher "glare screen" type of traffic barrier. This barrier has approximately 56" of its total height of 63" above ground after construction. In addition, since there will be a boulevard approximately 15'-16' wide between Lakeshore Place and the barrier, there should be ample space for landscaping to screen the barrier after construction while maintaining space to store plowed snow. Ramsey County will include the properties in the northeast quadrant of I-35W and CSAH 96 in its contracts for appraisal and acquisition services for the project so that the noise wall there can be configured to accommodate future interchange improvements and maximize noise reduction at adjacent properties. The County�will not condemn these properties to facilitate the acquisition, but will negotiate to achieve a suitable settlement without the use of eminent domain powers. If the City's staff agrees that the conditions have been met, we request that a resolution granting municipal consent be added` to the City CounciPs agenda as soon as practical. Please let us know if there are any questions or ctarification needed: Sincerely, v�� seph Lux Planning Specialist Enclosure C: James Tolaas, Ramsey County Engineer/Director of Public Works Terry Maurer, Arden Hills Director of Public Works `� so��.�NEsoT9y�F � � Qo 5 pp Tppt� Minnesota Department of Transportation Metropolitan District 1500 West County Road B-2 Roseville, MN 55113 October 10, 2011 James Tolaas Director of Public Works/County'Engineer Ramsey County Public Works 1425 Paul Kirkwold Dr. Arden Hills, MN 55112 RE: TH 10/CSAH 96 NOISE ANALYSIS Dear Mr. Tolaas: r .�i', � Based on a meeting you had with Arden Hills Public Works Director Terry Maurer and North Area Engineer Mark Lindeberg, I was asked to review and comment on the noise analyses done for TH 10 that affected the Lakeshore Place neighborhood and to provide information on whether different heights or lengths of wall might meet the "reasonableness" threshold. In 2007, Arden Hills asked MN/DOT to extend a noise analysis completed as part of the I-694 Environmental Assessment (EA). In March, 2008, SEH, Inc. completed the TH 10 Barrier Study. That study showed that a noise wall in the southwest quadrant of TH 10 and CSAH 96 was not cost effective. A 20' high wall was analyzed and the�results showed that the wall woulcJ cost $5,839 per decibel reduced per residence. A 10' high wall was also modeled and the results showed that the lower wall would cost $10,875 per decibel reduced per resident. A separate noise analysis was performed for the EA done by Bonestroo for the TH 10/CSAH 96 interchange project, with similar, though not identical, results. The small differences in the analyses are largely attributable to daily differences in noise levels when measurements were taken as well as more detailed geometrics than used for the I-694 EA . This study showed that the cost per decibel reduced per residence would be $7,627. While the results of the finro analyses differ slightly due to studying different locations, there is a significant overlap in the areas studied and the results of varying wall height and length would likely yield similar results: the benefits of the wall decrease as the wall height is reduced, thus the cost/benefit ratio becomes worse with a lower wall. Varying the length of #he wall will perpetuate An Equal Opportunity Employer the relationship between the number of residences benefitted and the cost. There is simply not enough density of residences to meet the cost effectiveness threshold. We would also like to clarify that even i� this project could use the new FHWA/MN/DOT noise policy,(which it cannot) it would not allow vacant lots to be included in noise analyses unless a building permit has been issued. Including the three vacant lots on Lakeshore Place in the noise analyses would not alter the conclusion that there is not a cost effective noise wall design for this neighborhood. Sincerel , �2��.

Chromy, P.E., P.T.O.E. Subject: TH 10/CSAH 96 Noise Analysis Peer Review Per the request of the City of Arden Hills, Bolton & Menk has reviewed two formal noise studies that were completed in the area of TH 10 and`CSAH 96. These included the TH 10 Barrier Study, dated March 18, 2008 and the Environmental Assessment CSAH 96 and US 10 Grade Separation Project, �proved bYMn/DOT Office of State Aid on October 25, 2010. In addition, we have reviewed the October 11, 2011 review letter from Peter Wasko at Mn/DOT to James Tolaas at Ramsey County. Below is a summary of our review relative'to residences along Lakeshore Place/Old Hwy lO located southwest of the TH 10/CSAH 96 intersection: • The combination of the two referenced studies provides sufficient analysis of noise conditions and potential mitigation strategies for this azea. The two studies overlap the area in question. Additional study would result in the same conclusion and therefore not necessary. • Recognizing the studies were conducted independent from one another and for sepazate proposed highway projects; their results in overlapping areas vary a bit. This is due to slightly different assumpUons and modeling inputs. While a bit different, both sets of results appear valid and generally consistent. • Both studies provide the same general� conclusions for the area in question. Both found current noise levels exceed state and federal thresholds and warrant consideration of noise mitigation. Both found noise mitigation could be feasible in reducing highway noise levels by 5 dBa or more for adjacent residences. Both found the cost effectiveness of noise mitigation would NOT be reasonable relative to established thresholds. � I have contacted Anne Claflin at the Minnesota Pollution Control Agency (MPCA) to confirm that platted residential lots without homes are not to be included in cost effectiveness analysis. Even with the addition of three platted lots into the calculation, the noise mitigation costs would remain above the established reasonableness threshold of $3250 per decibel reduced per residence. • The conclusion in the October 11, 2011 memo that "There is simply not enough density of residences to meet the cost effectiveness threshold" is valid and summarizes the conclusion of both studies accurately. Neither Mn/DOT nor Ramsey County is offering to include noise mitigaUon up to the cost effectiveness threshold with remainder of cost being bome by the city. On the contrary, any noise mitigation as part of this project would need to be shouldered by the city or other local source in its entirety.
