Presenter
Presentation Notes
TDSP focused on improving the El Cajon Transit Center TDSP is a land use & mobility plan for the area around the El Cajon Transit Center. TDSP->Climate Action Plan. CAP is a policy documenting city actions to reduce GHG emissions (and meet statewide targets). TDSP->EIR ECTC located off I-8 between Main St off-ramp and El Cajon Blvd off ramp. Previous project presented by City in Jan located within this vicinity, El Cajon Blvd-Green Street Gateway.
• Project presented to the board at the January meeting
• Project funding provided by SANDAG Smart Growth Incentive Program and TransNet
• Improvements include: • Traffic roundabout, • sidewalks, • enhanced crosswalks, • lighting, • LID basins, • native street trees, • site furniture, and • bike lanes.
PROJECT DESCRIPTION SMART GROWTH PROJECTS
PROJECT DESCRIPTION SCOPE OF WORK
• Addresses key goals of the TDSP
• Installation of class IV bike lanes and streetscape improvements including landscaping, wider sidewalks, and street lighting
• Stormwater features to incorporate LID facilities: Biofiltration basins and planting strips
• Parkway plantings to be implemented: Native, drought tolerant trees and shrub species
Tree lined street + landscaped parkway
Flow through planters to reduce and treat stormwater at its source
Presenter
Presentation Notes
The TDSP proposes improvements along Main Street to develop a sense of arrival and place, creating a gateway between the transit center, Interstate 8, and downtown Main Street with transportation and pedestrian improvements such as Class IV bikeways and urban greening that support small-scale commercial uses with strong street frontages. Green Street Gateway Objectives: +Traffic calming strategies implemented through end of block and mid-block bulb-outs +Tree lined street strengthens the urban canopy and provides shade for the street and sidewalk +Implementation of green infrastructure through the use of bioswales to filter stormwater and reduce runoff +Enhanced pedestrian crossings create a safe environment for pedestrians +Material cues from Downtown Main Street are implemented within the “Gateway” ____________________________________________ Stormwater features to incorporate LID facilities: Biofiltration basins, planting strips to treat stormwater runoff for water quality and groundwater recharge Parkway plantings to be implemented: Native, drought tolerant trees and shrub species For heat reducing effects and to provide shade
PROJECT DESCRIPTION SCOPE OF WORK
• Preliminary design currently underway

PROJECT DESCRIPTION FUNDING
• Project currently funded by Transnet and Smart Growth Incentive Program by SANDAG• Project will support Disadvantaged Community
areas
• Request for needed project funding from San Diego River Conservancy
Current Funding: $2.5M
Requesting: $250,000
PROJECT DESCRIPTION LANDSCAPE ENHANCEMENTS
• Low Impact Development Stormwater Treatment Planters
• Low maintainance & durable plantings
• Street Trees
Presenter
Presentation Notes
Sustainability improvements for stormwater runoff, energy conservation (potentially w/ street lighting), and landscaping and street trees. Hydrologically, the project area drains to the County Ditch Creek, which then drains to Forester Creek, which is a tributary of the San Diego River, and ultimately the Pacific Ocean.
