PARTNERSHIPS Friends of the Jones Falls (FTJF)
• FTJF can assist with fundraising and outreach for most components of the GSI plan• Lead the coordination and implementation effort for Light Rail Trail • Coordinate with DPT and DPW about stream channel restoration adjacent Medfield Trail
Baltimore City DOT• Consult with DOT about expanding accessibility and traffic safety measures along 41st street• Discuss opportunities for restoration of eroded stream channel adjacent Medfield trail. This property
is City right-of-way managed by DOT
Baltimore City DPW• DPW should be closely engaged with design of wetlands, green roofs, and cisterns. Coordinate with
DPW about possible SWM fee reduction credits related to construction of these projects• Discuss opportunities for restoration of eroded stream channel adjacent Medfield trail. Restoration
may be eligible for funding through Stormwater Program
Baltimore City Forestry• Consult with Forestry about invasive removal and forest edge project• Consult with Forestry for canopy improvements along Light Rail and Medfield Trail connections
Medfield/Woodberry Neighborhood Associations • Neighborhood associations should be closely engaged with the Light Rail + Trail Connection
Projects, and any City improvements along 41st Street• Engage for Stream Cleanups and Volunteer Events
Area Schools• Consider environmental education partnerships with nearby schools, such as Poly/Western High
Schools and Medfield Heights Elementary School
GREEN INFRASTRUCTURE MASTER PLAN UNION COLLECTIVE | JULY 2020
Certain features will require unique maintenance tasks, particularly during early establishment.
Meadow • Planting through year 5-7: Mowing of new plantings will be timed to reduce invasives. Seeding and
overseeding must occur during appropriate seasonal windows. Hand weeding of particular invasives may be required if the invasive is rampant or particularly noxious.
• Once established: Maintenance is reduced to a late winter mowing and possibly a late spring mowing if there is weed pressure. Monthly inspections during the growing season are recommended to ensure the health of the meadow.
Wetlands • Bi-annual inspections needed to ascertain specific maintenance needs, including repair of eroded
areas, removal of sediment, clearing of inflow/outflow areas, removal of dead or unwanted vegetation, vegetation thinning
The Nature Trail• Requires regular inspection to ensure that the path and retaining materials are not compromised• Any signs of wear or erosion should be addressed immediately
Wetland & Boardway Decking • Need regular inspection and maintenance per the manufacturer’s or contractor’s specifications
(depends on chosen decking material and finish)
Native Plantings and Forest • Year 1 and 2: weekly watering and twice monthly weeding • Once established: water during drought, seasonal weeding, cutting back in late winter
