Bus Replacement Planning
LCISD Current School Bus Fleet Regular Program
178 buses Median age 14 years; average age 12.2 years Oldest 25 years; 82 are pre-1990 buses 9,100 miles per year on average per bus
Special Program 26 buses Median age 14 years; average age 11.2 years Oldest 20 years; 12 are pre-1990 buses 11,600 miles per year on average per bus
Observations on School Bus Fleet At 62%, LCISD has almost double the
percentage of 10+ year old buses as peer agencies
44% of the LCISD fleet is pre-1990 as compared to 16% of bus fleets nationally
There has not been a consistent procurement history
Older buses have high emission levels, high maintenance costs, poorer fuel mileage
Bus Replacement Planning
Criteria for school bus replacement schedule Years of service Miles of service Ongoing maintenance requirements/cost
Adopted Bus Replacement Criteria: Age 12 years
Denton ISD (12- 15 years) 13 years
Alvin ISD 15 years
Clear Creek ISD Northside ISD
16 years Humble ISD
20 Years Mansfield ISD
LCISD 2004-05 Maintenance Cost per Mile & Avg Annual Miles by Service Age of Bus Fleet
Recommendation: Regular Bus Replacement Plan LCISD Regular Fleet Replacement Plan
Regular Program Goal 15 year service life On average replace 13 buses per year (current fleet)
Special Program Goal 15 year service life On average replace 2 buses per year (current fleet)
Note: Annual replacement buses will increase as fleet expands to meet growth
Recommendation: Purchase Expansion Buses to Match Growth Assumes current policies continue Two growth scenarios base on 2005
demographic projects: “Most Likely” – student enrollment increases from
18,760 in 2004 to 32,508 in 2014 (+73%) “High Growth” – student enrollment increases
from 18,760 in 2004 to 34,731 in 2014 (+85%)

Capacity Most Likely High Growth
Recommendation: Increase Maintenance Capacity for Expanded School Bus Fleet Current facility is near capacity Additional capacity is required to provide
adequate space for expanding school bus fleet
One maintenance location increases cost to operate unproductive miles to reach all routes in large school district area
Requirements for Maintenance Facility Building
Maintenance bays Driver area
Parking
Bus parking and circulation Employee/visitor parking Fueling lanes/other
Requirements for Maintenance Facility Considerations
Right of way acquisition Construction Fixed operating costs Spreading expenditure over time Reduced operating costs by reducing
unproductive mileage Strategy:
Two facilities/100 buses each Located: southern and northwestern
