PROMENADE ACTION PLAN
P R O M E N A D EThe central core of downtown Redding will put the priority on business access and pedestrian safety for a great downtown environment. The existing 80’ ROW along a porion of Market Street (needs to be acquired) though the mall allows generous sidewalk widths to promote a mix of uses and a high level of pedestrian amenities to promote high levels of activity throughout the day. Opening the streets through the mall will allow for increased visibility and access to businesses for economic development.
DESIGN CONSIDERATIONS
•High levels of pedestrian activity should yield priority to the pedestrian, not the vehicle.
•Sidewalks as plazas are part of the public realm.
•Access and visibility to businesses.
•High turnover for parking spaces along street to promote business turnover.
•Minimal drive access points on sidewalk – promote alley access in rear of building.

PROMENADE ACTION PLAN
A L L E Y SAlleys are typically narrow streets that carry a low number of vehicles to access adjacent properties. In Redding, the alleys along the promenade have the best access to the parking garage and become the pathway for the arrival of visitors to the downtown and have taken on the ‘front door’ feel for businesses along the west side of the promenade. The role of the alley will change and the front door for businesses shifts to Market Street. Therefore alleys should be designed to accommodate pedestrians and low-volumevehiculartrafficneedingtoaccessbusinessesthroughtrafficcalmingandflexibleusestocreateusable public space as well as vehicular access.
DESIGN CONSIDERATIONS
•Flexible uses for transit, vehicular and delivery functions and pedestrian access.
•Different uses and activities at times of day.
•Lower vehicular speeds and volumes.•Narrow ROW.
PA S E O SPaseos are pedestrian only rights of way that connect two streets and designed with the pedestrian as a priority. These become interesting and dynamic spaces that can be tailored toaspecificcontextandallowforavariety of pedestrian uses. The spaces between buildings along Market Street connecting to the alleys,California and Pine Streets create an opportunity for increased pedestrian connections and dynamicflexibleusespaces.
DESIGN CONSIDERATIONS
•Flexible uses for pedestrians. •Movement through and activity within
the space•Visibility into and out of space

PEDESTRIAN ACTION PLAN
DESIGN ELEMENTS FOR PEDESTRIANS
Vibrant downtowns are places that accommodate different types of users and different times of day. Streets are the visible places of the city that not only allow for cars to pass through, but provide a place to shop, dine, play and meet. Streets must be safe, sustainable, multi-modal and economically viable as well as accommodatethrough-trafficandparking.
DESIGN CONSIDERATIONS
•Well designed streets attract more businesses which creates the street as a great public space.
•Streets need to be safe and designed to accommodate a variety of activities including walking, biking, sitting, parking, driving, shopping and working.
•Streetscapes will evolve over time are design features are implemented and businesses turnover.
• Intersections are shared spaces that need to be safe for all users and should consider size and spacing, signal timing and designate perceived zones for cars, bikes and peds. Park Once Strategies encourage walking through the strategic placement of parking so that most visitors are within a comfortable walking distance of their destinations.

M I X E D U S E S T R E E TThe downtown connector streets pass through a variety of use types including officeandfinacial,civic,residential,mixed use and the downtown core. Streetscape improvements needs to focus on separation and buffering of vehicular roadways and sidewalk spaces providing a usable public realm through landscape and sidewalk treatments to facilitate a pleasant space to walk or bike and live or work.
DESIGN CONSIDERATIONS
•Promote comfortable pedestrian and bike activity.
•Flexibility to balance parking access and pedestrian zone.
•Access to businesses including truck loading.
•Multiple drive access cuts to residentialandofficesandparking.
•Trafficcalmingforthroughtrafficfromeast to west.
•Visual consistency between mixed uses to further identify the downtown plan area.

PERMEABLE PAVING •An alternative to standard paving that reduces stromwaterrunoffbyincreasinginfiltrationintothe ground.
•Water is temporarily stored in rock base before being absorbed into the soil or discarded though subdrains.
CHANNELS AND RUNNELS•Concrete or stone lined paths to convey water
to that reduce the need for buried storm drains or allow water to reach a desired location for additional treatments.

BIO-RETENTION•Combines stormwater runoff with landscaping areatocollect,filterandinfiltraterunofffromroofs, streets and sidewalks to reduce pollutants andmirrortheinfiltrationtechniquesofnaturalsystems.
•Soil traps pollutants and plants uptake pollutants as water percolates through the system.
LANDSCAPE STRATEGIES
HARDSCAPE STRATEGIES
INFILTRATION AND SOAKAGE TRENCH• Infiltrationtrenchesare2-5’deepsubsurface
facilities with sand or course drain rock that allows on-site stormwwater detention by collecting and recharging stormwater to the ground.
BIO- SWALES•A type of bio-retention, swales are vegetated,
shallow depressions that capture, treat and infiltratestormwatertoimprovewaterqualitythrough removal of sediments and reducing runoff volumes.
•Typically, bio-swales include a subsurface infiltrationtrenchbelowamendedsoil.
•Can be incorporated in bulb outs, medians and streetscapeplantingincollaborationwithtrafficcalming
FLOW THROUGH PLANTERS•A type of bio- retention, hard edged planters thatallowwatertoinfiltrateintoanunderdrainsystem for reuse.
•Highly adaptable and ideal in high-density urban settings.
INFILTRATION BOARDWALKS•Segments of the sidewalks can be constructed
with boardwalks to provide pedestrian throughways over planted drainage rock or amended soils in a trench that allow stormwater to pass beneath the walking surface.
PERVIOUS STRIPS•A type of bio-retnetion, long linear planters that
capture and slow runoff.•Are not as effective as bioswales and can
mitigate runoff but not treat the full capacity of a stormwater event.
MATRIX OF USES
= Recommended Location
GREEN STREETS ACTION PLAN
STORMWATERMANAGEMENTSTRATEGIESIn urban settings where building roofs, street paving sidewalks and parking lots prevent water from absorbing into the ground, rainfall collects into pipes gathering chemicals, oils and other by-products of urban life which accumulates in our rivers, lakes and streams and keeps water from recharginggroundwateraquafers.During large storm events, run off contributestoflooding,erosionandsewer surcharges. Stormwater management tools provide broad range of opportunities to apply to a range of street types to make streets more aesthetically pleasing and provide ecologicalbenefitstocounteracttheimpacts of urban development on the local ecosystem.
DESIGN CONSIDERATIONS
• Improvewaterqualitythroughremovalof sediments.
•Slow the movement of water from storm events by holding it on-site for longer duration of time.
• Increase pervious surfaces to minimize runoff volumes.
• Increased value to traditional infrastructure to minimize pipe sizing and reduction of impact to wastewater treatment and re-purposeing of greywater, and increased visual aesthetic of landscape areas.
