The Prince George’s County Council adopted a $5 billion spending plan on Wednesday for the fiscal year that begins July 1 that boosts investments in education and public safety, keeping intact the priorities of County Executive Angela D. Alsobrooks (D). The budget — which is nearly 10 percent larger than this year’s — is designed to help the county navigate the long tail of the pandemic while equitably providing resources to county residents. The Board of Education will see its budget rise about 12 percent under the plan, to $2.63 billion, accounting for the largest slice of the pie. Public safety resources such as police, fire and corrections departments follow, receiving a combined $827 million.
