Important Measure K Update

On April 27, 2015 the Governing Board took a courageous step forward and approved $15,763,850 for the second phase of Measure K funding.  This was not a decision easily reached.  The essential question was, “Given the reality of limited funding (and the age of JME, LJE and JSE) how do we prioritize facilities projects in a way that supports our highest vision for 21st century teaching and learning programs, while also addressing safety and maintenance concerns district-wide?”  The board carefully evaluated the many options before them and approved a Hybrid Project List that aligns to the recommendations of architects Hibser –Yamauchi.  While there are far more projects than funding allows, the goal was to leverage the funds in a way that best supports the educational, health and safety needs of students and staff.  

Highlights of the approved project list include:

  • District-wide replacement of classroom furniture
  • Domestic water system, boiler replacement, fencing and reconfigured playfield – John Muir
  • HVAC including insulation, roofing and energy management system, bathroom renovation and fencing – John Swett
  • HVAC including insulation, energy management system, fencing and field renovation – Las Juntas
  • Boilers, fencing and xeriscaping – Morello Park
  • Setting up an additional Science lab, classroom upgrades, CTE renovation (building F) and auditorium sound system upgrade, stage lighting and projection screen – MJHS
  • Building J renovation to support STEM and CTE related programs, new classroom building with 6 classrooms and other flexible spaces, D wing renovation to support CTE programs and F and H  modernization – AHS

El 27 de Abril, 2015 la Cámara Gobernante tomó un valiente paso adelante y aprobó $15,763,850.00 para la segunda fase de financiamiento de la Medida K. Esta no fue una decisión fácil de lograr. La pregunta esencial fue, “Dada la realidad de financiamiento limitado (y la edad de JMS, LJE y JSE) cómo damos prioridad a los proyectos de las facilidades en una forma que apoye nuestra más alta visión para los programas de enseñanza y aprendizaje del siglo 21, mientras también tomamos en cuenta la seguridad y preocupaciones de mantenimiento en todo el distrito?” La Cámara evaluó cuidadosamente las muchas opciones delante de ellos y aprobó una lista de Proyecto híbrido que se alinea a las recomendaciones de los arquitectos Hibser –Yamauchi. Mientras que hay más proyectos que los fondos permiten, la meta fue balancear los fondos en forma que mejor apoyen la necesidad de educación, de salud y seguridad de los estudiantes y personal. Lo más importante en la lista del Proyecto aprobado, incluye:

  • Remplazar muebles del salón en todo el distrito

CA Physical Education Requirement Accountability

Students in grades 1-5, at all four elementary schools in the Martinez Unified School District, actively engage in the California requirement of 200 minutes of Physical Education every 10 days.  In order to assure compliance with this legal requirement, each site has established “Prep C” protocols for those grade levels that may not reach the 200 minute requirements due to minimum days, teacher prep, and / or assemblies.  These established practices of running laps, dance & movement, and cardio-conditioning outside of the PE class are documented and verified by the site administration on a monthly basis.
