4 Mission Statement: Project Purpose Establish an ecodistrict that transforms the 10th Street and Maryland Avenue corridors into vibrant, well-connected places to commemorate, visit, work, and live in a manner that creates a national showcase of sustainability through innovation, technology, and design. Goals: Create a Livable Community, Workplace, and National Cultural Destination Create a National Showcase of Sustainability Ensure Mobility To, From, and Within the Area for all Modes of Travel Create a Healthy Urban Ecosystem Goals 4

5 Overview What is an Ecodistrict? It captures, manages, and reuses energy, water, and waste beyond a single building to a group of buildings within a precinct It includes transportation choices and a mix of uses within a neighborhood It creates a neighborhood of connected parks, plazas and open spaces for a vibrant, green, and walkable community 5

46 Successes and Challenges What are the challenges moving forward? The funding and phasing of infrastructure. The need for a governance entity for implementation and ongoing operations. The coordination and legislative actions needed to improve efficiency of the central utility plant. Prioritizing multiple agency missions and objectives. The need for private sector participation and ability to interface with the private sector. 46
