Introduction

IntroductionExecutive Summary

This report documents the findings of the Mitigation and Enhancement

Subcommittee (M&E) of the I-35W Access Project Advisory Committee

(PAC) as amended and accepted by the PAC on October 29, 2002.

The Subcommittee was formed in the late summer of 2000 of interested

members of the PAC. The membership of the Subcommittee was almost

exclusively composed of those PAC members who represented residential

neighborhoods. The Subcommittee met 36 times in the course of two

years in addition to the regularly scheduled monthly PAC meetings.

In addition to these 60 regular, open-to-the-community meetings, the

Subcommittee also sponsored two community workshops on the project

and arranged neighborhood forums in Bryant, Central, Kingfield,

Lyndale, Phillips, Powderhorn, and Whittier neighborhoods. Many

of these neighborhoods actually conducted multiple meetings exclusively

on the I-35W Access Project. The Subcommittee also directed consultant

staff to develop working relationships with Sabathani Community

Center, C-SNAP (Citizens for a Sensible Nicollet Avenue Plan), Sherman

Associates (K-Mart Site Redevelopment), and most recently, residents

of the Healy Block. At the request of the Kingfield and Lyndale

Neighborhoods, consultant staff also attended monthly mitigation

meetings with neighborhood residents for approximately one year.

The Subcommittee also sponsoredone meeting exclusively on the 38th

Street Bridge Ellipseabout proposal.

The Subcommittee believes that if it’srecommendations are incorporatedinto the project, its vision of creatinga project that enhances the livesof residents by improving the safety,well-being, and cohesion of theneighborhoods adjacent to I-35Win South Minneapolis will occur.

Specifically, the recommendations:

� Manage traffic effectively, relegatingcommuting and commercial trafficto commercial and communitycorridors and effectively allowingonly local, residential traffic useson residential streets.

� Identify traffic managementstrategies that efficiently direct andregulate traffic movements from andto I-35W.

� Improve pedestrian safety andamenities throughout the project area.

� Improve transit operationsthroughout the project area.

� Identify appropriate land uses forremnant parcels created as a resultof the I-35W Access Project thatenhance community identity,cohesion, and safety.

� Develop conceptual plans forcreating a safe link between the 29th

Street Greenway and transit facilitieson Lake Street.

� Develop requirements for land-scaping and maintenance thatenhance and maintain an attractiveappearance reflective of the urbancharacter of the corridor and expec-tations of neighbors.

� Develop conceptual plans for thearchitectural facades of all highwaystructures to be constructed as partof the project.

� Develop recommendations thatintegrate public art and communityvalues into the development of newinfrastructure during preliminaryand final design.

In summary, the Project AdvisoryCommittee accepted these recom-mendations of the Mitigation andEnhancement Subcommittee andincorporated them into the preferredbuild alternative described in thisdocument.

General ClarificationsThis report only lists the FinalRecommendations of the Subcom-mittee. These recommendations arebeing made only after extensive dis-cussion by the Subcommittee, PAC,and public review. To avoid creatingtoo cumbersome of a document, thereport typically does not identify theunderlying issues and the rationalefor these recommendations. Theunderlying issues and the rationalefor the Subcommittee’s recommen-dations are documented in themeeting minutes of the Mitigationand Enhancement Subcommitteeand the meeting minutes of theProject Advisory Committee.

The need to coordinate these recom-mendations with other infrastructuredevelopment activities outside theproject area is assumed, particularlythe recommendations for city streets.Streets do not occur in isolation andthe Mitigation and EnhancementSubcommittee and the PAC recognizethat their recommendations needto be coordinated with neighborsand neighborhoods outside theproject area. Such coordinationwill occur during final design.

After early discussions, the Subcom-mittee restricted its recommendationsto an area bounded by FranklinAvenue on the north, 42nd Streeton the south, Blaisdell Avenue onthe west, and 5th Avenue on the eastin order to produce recommendationsthat were equitable to all neighbor-hoods. This area was confirmed bythe Subcommittee and the PAC asdefining the maximum geographicallimit that the I-35W Access Projectwill be asked to mitigate or enhance.

Although the Subcommittee andthe PAC recognize that many of thedesign concepts to mitigate adverseimpacts and enhance the livabilityof south Minneapolis have merit ontheir own with or without an I-35WAccess Project, they have strived togenerate recommendations that areappropriately tied to the I-35WAccess Project, fulfilling the visionof Congress to enhance the livabilityand economic vitality of southMinneapolis by improving access tothe regional transportation network.

Coordination with the PAC bythe project sponsors is anticipatedthroughout the development of allaspects of the final design. The PACwill remain engaged during thedevelopment of detailed designdocuments so the intent of the miti-gation and enhancement recommen-dations, as adopted by PAC, are fullyrealized. The final section of thisreport lists those items that the PAChas identified as needing furtherdesign development during the finaldesign phase of the proposed accessproject if the Build Alternativeis selected.

Introduction

Subcommittee Vision Statement"Create a project that enhances the livesof residents by improving the safety,well-being, and cohesion of theirneighborhoods adjacent to I-35Win South Minneapolis."

Subcommittee Goals 1. Traffic in the project area mustbe managed so that commercialand commuting traffic is relegatedto commercial corridors and onlylocal residential traffic usesresidential streets.

2. Identify traffic managementstrategies that efficiently direct andregulate traffic movements fromand to I-35W while simultaneouslyimproving pedestrian safety through-out the project area.

3. Develop conceptual plans forsidewalks, crosswalks, and associatedpedestrian amenities that enhancethe pedestrian experience, particularlyits movement and safety on 26th,28th, Lake, 31st, 35th, 36th and 38th

Streets between Blaisdell and 5th

Avenues, especially where theseroads cross over or under I-35W.

4. Develop conceptual plans forimproving the function, location,and appearance of transit stops onLake Street between Blaisdell and 5th

Avenues, including the proposedtransit stations at I-35W.

5. Identify appropriate land uses forremnant parcels (created as part ofthe transportation project) that will

maintain or enhance communityidentity, cohesion, and safety.

6. Determine if connecting the 29th

Street Greenway to transit facilitieson Lake Street is necessary. If neces-sary, develop conceptual plans thatlocate and design a safe link betweenthe 29th Street Greenway and transitfacilities on Lake Street.

7. Develop conceptual plans for newcommunity gateways at the entrancesto the community from I-35W thatreflect the history, character, and vital-ity of the respective neighborhoods.

8. Develop conceptual plans andmaintenance requirements for land-scaping the freeway corridor toenhance and maintain an attractiveappearance reflective of the urbancharacter of the corridor and theexpectations of neighbors.

9. Develop conceptual plans for thearchitectural facades of highwaystructures, particularly bridges,retaining walls, and noise walls thatwill be constructed as part of theproposed project, especially the newbridges proposed at 38th Street, 31st

Street, Lake Street, and the "fly-over"exit to 28th Street.

10. Integrate public art that reflectsthe values of the community intonew infrastructure development.

Street Character

Street CharacterIntroduction

A primary goal of the Mitigation and Enhancement Subcommittee

was to create a street network that induced drivers to use particular

roads depending on their reason for being in the project area. The

fundamental principle was that commuting traffic needed to be

funneled to those routes that had been designed to handle such

traffic, primarily commercial routes, and residential streets needed

to be reserved for neighborhood use.

The recommendations of theSubcommittee and PAC related tostreet character are presented in thischapter. The chapter is divided intofour sections. The four sections are:

1) Street Character ClassificationMap – A map which classifies all ofthe streets in the project area into oneof five types by how the PAC wantsthe street to be used by travelers andexperienced by neighbors.

2) Prototypical Intersection Plans –A set of ten plans that ideally illustratethe design of how selected typesof streets would intersect witheach other.

3) Street Character Element Matrix –A list, by types of streets, what designelements would be utilized to estab-lish the character of the street.

2-1

4) Prototypical Streets – A set of urbandesign plans that illustrate how thestreet character classification systemand layout of prototypical intersec-tions would be applied to six repre-sentative streets in the project area.

Street CharacterClassification MapThe map, Street Character Classifica-tion, indicates the classificationscheme developed by the Mitigationand Enhancement Subcommittee.In most cases it reinforces the variousclassifications assigned to streetsby the city, county, or state. In somecases, however, it contradicts previousclassifications and will require negoti-ations with governmental authorities.

The Technical Advisory Committee(TAC), composed of representativesfrom transportation agencies from

Hennepin County, the City ofMinneapolis, the MetropolitanCouncil, and the State of Minnesota,has reviewed the classification map.In general, it agrees with the classifi-cation system and with continueto work with PAC to develop plansthat meet the vision and goals ofthe Mitigation and EnhancementSubcommittee.

Not all symbols on the StreetCharacter Classification Map arediscussed in this chapter of the report.Specifically, recommendations for the"Special Traffic Management Zone"as marked on the map are listedunder the Traffic Managementchapter of this report.

Figure 2: Street Character Classification Map This map illustrates the street character classification system recommended by the Mitigation and Enhancement Subcommittee and adopted by the Project Advisory Committee. Street character is based on how residents of the community want traffic managed on theirneighborhood streets. Note that only five colors are used to depict the six types of street character discussed in the text of this report. The map does not differentiate between streets designated as Residential High Traffic One Way and Residential High Traffic Two Way. Both streets share the same color on the classification mapbecause, except for traffic direction, their character is essentially identical.

PrototypicalIntersection PlansThe Mitigation and EnhancementSubcommittee created a set of tenprototypical intersection plansto guide in the development ofprototypical streets. The plans weredeveloped to guide the design ofstreets, on-street parking, sidewalks,boulevards, medians, crosswalks,and transit stops. These are idealintersections and do not necessarilyreflect actual conditions found inthe City of Minneapolis. To simplifythese plans, accommodations forbicycle transportation are notincluded but are illustrated anddiscussed elsewhere in this report.

Application of these prototypesto specific intersections will bedeveloped during final designby the appropriate transportationauthority in coordination with PAC.

Figures 3A-3J:Prototypical Intersection Plans

One key to effective traffic management is thedesign of intersections. The Mitigation and

Enhancement Subcommittee developed theseten prototypical intersection plans to illustrate

all of the possible combinations of intersectingstreets. The intersections are designed to facili-tate movement between streets handling com-muting traffic, ensuring that commuting traffic

stays on commuting routes. They also passivelyregulate access from commercial and community

streets to residential streets through the use ofbump outs, medians, crosswalks, and other

urban design measures.

from the street by only a sidewalk.Urban parking is on the street, onsurface lots behind the buildings,or in parking ramps.

Thus, the same street can easily havevery different character dependingon location. The dimensions of thestreet itself do not create a rural,suburban, or urban street. This doesnot mean that the street does notinfluence the character of the adjacentproperties. On the contrary, the streetmust support the activities of peopleon the adjacent properties, that isit must provide optimal volumesof traffic at optimal rates to supportthe desired land uses and layout ofthose land uses. The street must bedesigned not to stifle nor overwhelmadjacent land use. Succinctly,the Mitigation and EnhancementSubcommittee referred to this princi-ple as, “Putting commercial trafficon commercial streets, and residentialtraffic on residential streets.”

In an urban setting, the location,form, materials, and other architec-tural features of buildings largelydetermine the character of the streetand, in turn, affect the character ofother design elements that reinforcethis authentic urban character. Theseare the elements that compose thepublic realm. These elements signifi-cantly contribute to the livabilityof the city. The use and placementof these elements are determinedby what type of street characteris being sought.

The following matrix lists thoseelements that are recommended

Street CharacterElementsThe character of a street is establishedand maintained by many factorsbeyond the dimensions imposedby the need to move vehicular traffic.Land use alone typically creates a criti-cal context. A 4-lane street througha corn field is different from a streetwith the same dimensions in a city.

Even if the adjacent land use is iden-tical, local building codes could createstreets with very different characters.Two streets with the same dimensionsand the same land uses but laid outin accordance with very differentbuilding codes – one suburbanand one urban – may have widelydifferent characters.

For example, a 4-lane street in a sub-urb or the same street in a city, bothwith the same retail land use, mayhave very different characters. Bothstreets, in this example, would beflanked by retail stores. However,stores in the suburb would typicallybe limited to one or two stores.Suburban stores are frequentlymassed together in malls with indi-vidual stores only accessible fromthe interior of the building. Theyalso, typically, have large encirclingparking lots. In the city, storesfrequently occupy the first floorof multistory buildings with officesor housing over the stores. In anurban setting, the buildings are usu-ally massed shoulder to shoulderwith individual stores having theirown entrance from the street. Thebuildings are typically separated

for each of the six types of streetin the project area.

Prototypical StreetCharacterThe Mitigation and EnhancementSubcommittee applied the prototypi-cal intersection plans and the streetcharacter element matrix to a setof six prototypical streets. These sixstreets were selected because of theirimportance to the community. TheSubcommittee believes that these sixconcepts are transferable to otherstreets in the project area. The sixprototypical streets are:

� Lake Street – prototypicalcommercial street

� 38th Street – prototypicalcommunity street

� 28th Street – prototypical residentialhigh-traffic one-way street

� 36th Street – prototypical residentialhigh-traffic residential two-way street

� 35th Street – prototypical residentiallow-traffic residential street

� Stevens and 2nd Avenues –prototypical residential parkways
