A. The Project Agua Street Scape is a neighborhood street network typology that is designed to retain stormwater runoff within the Miramonte Neighborhood along Camino Miramonte. The intention is to passively harvest on-site stormwater runoff for vegetation and infrastructure enhancement. Along with water retention, the unique infrastructure improvements will increase the Miramonte Neighborhood presence within the Tucson community as well as strengthening the community outdoor interactions.

Tucson christmas wash watershed
project site
B. The Problem The Tucson Regional Watershed is an overall watershed coverage that originates at the peak of the Catalina’s and Rincon Mountains, which then mitigates runoff to the lower basin of the Santa Cruz River. The volume of runoff differentiates during varying seasonal climatic occurrences (Monsoon vs. Spring) and precipitation fluctuations. This watershed and its minor watersheds is the reasoning for the urban flooding issues in Tucson.

The project site is located within the urban context of the Tucson metropolitan area. The site is a neighborhood street within a urban block called the Miramonte Neighborhood. Consequently, Camino Miramonte is within the public right-of-way justifying it’s provisional code requirements to be allowable only with approval of the Zoning Administrator and the Department of Transportation. The cross sectional design limitations extend from property line to adjacent property line. Everything that is documented in this site analysis is only within the public street limitations.

The Miramonte neighborhood block consists of high-intensity commercial buildings to the north, low density residential homes to the south, with east and west edges that are predominately office, commercial, and high density residential. The internal built environment within the edges of the block is generally residential. The major east to west route through the site is 3rd Street which is a designated bicycle route. It then connects to Himmel park to the west onward to the UA. The contrast in commercial and residential zones has created a desire to pursue transitional opportunities between the differing zone typologies along the circulation paths. Unwanted noise and exhaust pollution during Camino Miramonte vehicular peak times instill an unwelcoming pedestrian experience.

Beginning at El Con mall, where the rainfall is collected from the asphalt parking lot, the stormwater begins it’s journey north using the streets as it’s conveyance path. The first neighborhood it travels through is the Miramonte Neighborhood. It then crosses below Speedway and flows through the Palo Verde, Doolen-Fruitvale, La Madera Cabrini, Richland Heights East, and Rillito Bend Neighborhoods. The Christmas Wash water runoff consequently ends it’s journey at the Rillito River. This project is only covering the Miramonte Neighborhood district along the Camino Miramonte street. One proposal of network phasing would be to design each neighborhood individually by one overall network system. Once one neighborhood has been design specifically using water mitigation strategies, the next phase will to continue northward and design the adjacent neighborhood typology. As a result, all neighborhoods along the Christmas Wash trajectory will have individual stormwater design implementations all holistically resolved by one network system.

Unlike many typical streets in Tucson, Camino Miramonte is an inverted crown condition road. Which means that the street concaves inward at the road centerline so that the water is mitigated in the middle. However, the side streets that cross perpendicular to Camino Miramonte are convexed outward so that the stormwater runs along the curb edge. In the event of a high rainfall occurrence, the street fills up like a canal within the urban neighborhood. The water that flows through Camino Miramonte can only be deviated by the existing stormwater drains. In contrary, the side streets push the stormwater along the edge of the road into Camino Miramonte. Since the water is already along the curb and not in the middle of the road, this creates an opportunity to redirect the water via curb cuts into the residential/commercial parcels where it pools and settles into the ground naturally.

As an outreach exercise, we attended a Miramonte Neighborhood Association monthly meeting and conducted a few interactive activities to gain local insight as well as design inspiration. Along with a typical written survey, we asked the Miramonte communities members to identify problematic areas along Camino Miramonte.

C. The Approach Currently, the existing road width of Camino Miramonte is approximately forty feet, whereas a typical two-way street is around twenty-four feet in width. The intention is to provide designated car lanes, bike lanes, and pedestrian lanes in order to control the flow of traffic and improve safety. In doing so, we propose to use natural vegetation as a buffer median in specific areas along the street to separate the vehicular lanes without adhering to any existing residential driveway. Our organizational approach to achieve this goal is to use a “Kit of Parts� modular system as a way to control the outlook, experience, cost, and water retention strategies.

Over the course of the year, it is evident that due to the existing conditions, vehicular traffic seems to dominate the neighborhood activity. However, with the implementation of the flood strategies and enhancing the sidewalks and bike paths, there will be a higher density of pedestrians. It is also possible that the summer seasons will naturally have a lower chance of pedestrian activity than winter due to thermal comfort. JAN

A. PEDESTRIAN LEVEL • Improve walk-ability along the street while enhancing the bicycle route pathway by use of natural/built shading systems, green infrastructure, and distinct pedestrian routes. • Provide attractive built landscapes along Camino Miramonte in hopes to invite more people into the neighborhood • Improve the existing lighting quality by providing attractive street lighting that are economical and environmentally appropriate. B. VEHICULAR LEVEL • Improve traffic mitigation through the different zone typologies by implementing transitional elements at street intersections. • Implement landscape buffers to reduce vehicular sound and light intensities. • Eliminate on-street parking along Camino Miramonte (without obstructing existing driveways) in order to provide space for green infrastructure and pedestrian pathways. C. ENVIRONMENTAL LEVEL • Utilization of passive stormwater mitigation strategies to control the surface runoff volumes along Camino Miramonte. • Implementation of active and passive stormwater storage management on a neighborhood scale. • Utilizing natural basins to enhance evapotranspiration and natural vegetation growth.

NEIGHBORHOOD APPROACH
A B C D E
At the intersection of 2nd Street and Camino Miramonte, there will be a roundabout that will serve as the first vehicular buffer before entering into the R-1 (low-density residential) zone. The vehicle will naturally slow down and become aware of itâ&#x20AC;&#x2122;s context. Solar street lighting will illumate the pathways and road for visual safety while promoting sustainability. Signage will also be implemented in the roundabout providing a welcoming presence into the neighborhood. During a rain event, the stormwater will flow into the curb, median, and roundabout basins. Any overflow will flow outward by way of curb cuts.
38
39
NEIGHBORHOOD PEDESTRIAN PATH
A B C D E
Traveling southward along Camino Miramonte, the pedestrian path promotes walkability by incorporating designated pathways, seating, and shade. The sidewalk and bike path are made with pervious materials like permeable concrete to allow any runoff to flow downward into the earth. Any residual overflow will flow into the road and is collected by the median berms and roundabouts. The median berm is broken up in designated areas to respond to existing residential access drives. There are curb cuts along the median to accept any runoff that pass the permeable boundary edges.
40
41
NEIGHBORHOOD INTERSECTION
A B C D E
A typical intersection beyond 2nd street will incorporate custom signage to promote wayfinding and provide unique character to the neighborhood. At the intersection corner, there will be curb basins that will collect any runoff flowing along the edge of the normal crown road side streets. To engage bicycle safety, pavement markers, materiality change, and designated lanes clearly separate the bike and vehicular paths.
