DESIGN COMMITTEE & STAFF INPUT:

SPRING, SUMMER, FALL, WINTER 2021/2022

BIG IDEAS

No long hallways, we want a connected school.
Access to the outdoors is key – for learning and play.
The Library should feel connected but also a quiet refuge for kids.
The iLAB needs to be in the center and up front, showing our commitment to STEM.
A multipurpose commons where we can dine, gather as a community, and celebrate the performing arts

“At the current River Grove, there is limited quiet space to build relationships with students.”

“The Pods are isolating, they hinder collaboration.”

“Biophilic design should be embraced to help students connect to nature and impact their emotional wellbeing.”

RIVER GROVE – SITE

The building is nestled into the site with views to the large established trees.
Classroom wings create a learning courtyard facing the western tree grove, creating multiple outdoor learning zones.
Separate parent and bus loading zones.
A south-facing learning garden with covered classroom area is adjacent and available to outdoor dining and gathering.
Kinder play area for younger kids with covered classroom.
A variety of outdoor movement and play opportunities to meet the needs of all kids with an accessible playground.

Path to Net Zero

Electrification - All systems included in the design are electric, no fuel fired systems.

Existing Building Comparison - 70% energy use reduction compared to an average, existing elementary school in Portland’s climate.

Beyond Energy Code - 30% energy reduction compared to a code minimum, new-construction elementary school.

Solar PV Array - 32% of energy consumption covered by PV Array annually.

Microgrid – 250kW battery will reduce peak electricity demand by an annual average of 18%; system will charge when the grid is cleaner and discharge when grid carbon emissions are high reducing overall building carbon emissions.

PV Solar Array

150 kW array offsets the building load during the day, reducing energy consumption from the grid.

Air-Source Heat Pumps

Outdoor air for ventilation is conditioned by extracting/rejecting heat to the ambient air.

Battery/Microgrid

Onsite battery storage; building micro-grid to interact with local electrical grid, reducing peak electrical demand and building carbon emissions.

Heat Pump Water Heaters

Domestic hot water is heated by extracting heat from ambient air.

BUS & CAR CIRCULATION

River Grove Re-Imagined Neighborhood Association Update

May 7, 2022

+

Separating Cars and Busses follows national best practices for school site design and has been voiced by the school community as being an important design element.
The lots are designed to have adequate parking and also to maximize the curb space needed to accommodate safe student pickup and dropoff for both parents and busses, thereby minimizing the queueing that occurs on the street.
The driveway entrance/exit for busses is in the same place as the current exit. Sight distance evaluations confirmed there is adequate site distance available at both driveway locations.

STATS

Existing Lot: 28,957-sf. and contains 59 parking stalls.

New parent/visitor lot: 20,566-sf of pavement with 23 parking stalls, New bus lot is 28,837-sf of pavement with 45 parking stalls.

The total impact is an increase of 20,446-sf of pavement, an increase of 9 parking stalls, and an increase length of onsite queueing for both parent and bus loading.

TREE #139 - PLAN 1

MOVE BUILDING WEST AND RECONFIGURE 4 CLASSROOMS

River Grove Re-Imagined Neighborhood Association Update

May 7, 2022

+

Response to building shift & tree 139

Tree 139 requires 44’ clear of building and hardscape (parking lots) from the base of tree in all directions.
Shifting the building west 44’ would require a 48” doug fir, two 27” doug firs, two 29” doug firs, and a 34” giant sequoia be removed in addition to several smaller diameter trees in the western grove.
Tree 139 has co-existed with the existing buildings and has adapted to the hydrology. Changing the land use around the tree may impact the flow of water through the soils and may have an adverse impact on the tree causing its decline.
Shifting the building west reduces the distance to the property line which is not allowable given the height restrictions under the city’s building code.
The western grove is on a hill. moving the building would require excavation of the hill and building retaining walls to hold back the earth - negatively impacting the trees and adding significant costs.

Response to Classroom Relocation

Relocating the 4 classrooms (2 downstairs, 2 upstairs) results in a significant reduction of window area for four other classrooms (labeled 1 and 2). Reducing daylight, views, and creating an inequitable experience.
four classrooms, the iLAB, and the Library are now buried deeper into the building, reducing daylight & views.
The shared extended learning area windows are reduced.
The courtyard is the place of connection for the entire community of learners. this redesign severs the connection between the two classroom wings
