The proposed building for the new workforce center will sit between two single story existing buildings.

To the West sits the existing work force center that is currently undergoing site work for storm water management. To the East sits the privately owned Micky’s Liquor.

SUNLIGHT CONDITIONS: SITE 1112 PLYMOUTH AVENUE

Both existing buildings cast relatively short shadows during the summer, but stretching longer during the Winter months. The proposed building will cast an approximately 20’ shadow to the North on the longest day of the Summer. In the Winter, the daytime shadows could span multiple properties and hundreds of feet, forcing increased heating costs to adjacent properties.

SOIL CONDITIONS: REGION 1112 PLYMOUTH AVENUE

All the soils in the region are considered “Urban Land” meaning there has been high disturbance and variability due to construction, residential neighborhoods, and impervious surfaces. Despite this there are some interesting takeaways: Lester: Potential of being loamy and well drained.

Udorthents: Historically low spots in the landscapes that have been filled to match adjacent grades. Generally areas of early development.

Dundas: Debris from glacial till, likely not well drained.

Udipsamments: Flood plain accumulation but more recently urban fill, unlikely to flood.

Duelm: Loamy sand stream terraces from out wash.

Based on the soil borings by BRAUN INTERTEC from 2017, the top layers are mostly Clayey or Silty Sand. Also, seeing a consistent barrier at 13’ to 14’ down, except for B-10 that hit a refusal point much more shallow at 8’. There is a risk of bedrock below native top soils. No water was observed while drilling these 5 holes. *BRAUN INTERTEC 2017

HYDROLOGY: REGION 1112 PLYMOUTH AVENUE

Graco Inc.

Looking at flooding potential in North Minneapolis a few things stick out. First, the FEMA flood plains along the Mississippi River’s edge (light purples). These are areas of industry imperviousness and could pose a risk in the future if flooded. Second, flooding around golf courses shows means for concern. Due to pristine turf management, pesticide runoff has been known to pollute surrounding water bodies.

Finally, constructed storm water ponds to help hold water during storms that peak the system ensure flood mitigation for some areas of the region. They also act as parkland with potential for pollinator habitat.

Calculation for a 1.5” Rain Event North Roof of Building: This side of the roof will shed ~184 gal/ min through the single downspout directly into the ally.

South Roof of Building: This side of the roof will shed ~184 gal/ min onto the southern turf lawn through 2 downspouts.

Western Parking Lot: This lot is bounded by a curb that directs water runoff into the street. It will sheds ~141 gal/min.

South & East Turf Lawns: The turf surrounding the building will shed ~51 gal/min directly into the storm sewers on site.

Eastern Vacant Parking: This asphalt lot slopes to the SE corner and will shed ~440 gal/min.

Similar to the Localized Temperatures map, Habitat Suitability in the region relates almost directly to impervious surfacing. Areas of impervious surfacing like in the North Loop, rail road changing stations, and major roadways show low suitability.

EXISTING VEGETATION/HABITAT: REGION 1112 PLYMOUTH AVENUE

Inversely areas along creeks and rivers, parkland, and already native vegetated swatches of the city show higher suitability for expanded pollinator habitat.

The area surrounding the Plymouth Avenue sites shows a local business corridor with lower than average suitability. Despite this, it is surrounded by higher than average suitability, and shows potential to be a steward for change.

The site does not have a large variety of tree species, but due to some mature Maple and Ash trees, there is some nesting potential. The lack of mature trees mean increased cooling costs in the summer, decreased nesting habitat for birds, and increased heat island from open impervious surfaces.

The two parcels have a combined 791 linear feet of boulevard potential that is commonly mowed turf that could participate in the Boulevard to Bioswale program.

Also, the ~11,000 sqft that is currently mowed turf could be converted into something more pollinator friendly.

Habitat in Boulevards Corridors Project Site

The corridor planning and assessment for the North Minneapolis region shows many things. Through analysis of the layers voids throughout the city begin to emerge. Voids showing reduced tree canopy and reduced pervious surfaces.

Also, the loss of pollinator and bird habitat create large vacant “dead” spaces. Finally, reduced access to the Mississippi River and concentrations of permits to pollute in low income areas.

Access & Equity

By overlapping layers of information a few key concepts come to light creating promising corridor strategies. First is climate resiliency and the mitigation of heat island and storm water run off. Second is the need for increased habitat that connect suitable areas of the city as we as returning industry to nature. Third is to ensure equal community access to nature and healthy environments throughout the city.

This process can then be applied to a more specific approach, like at the workforce center and for plant growth.

At the center, students and workers (Wenberg, 2020) would construct and deconstruct different types of lattice, post, and panel assemblies. The assemblies would either have a footer mounted base or be modular on wheels to be moved around the site. By doing this, research can be gathered on whether assemblies gather more CO2 closer to roads, impact of the plant growth on CO2 harvesting, and the impact of the MOF on the plant’s growth.

Due to the recyclability of the material, the studies can be done over and over again in many different situations. The idea of “Capture, Concentrate, Convert” can be taught in real time. Though the research to this point has yet to scale up to, the potential when it eventually does is huge.
