Many Americans entering their golden years are looking for a way to remain in their homes while growing older. At the same time, these senior citizens want the luxury of a support system to help them navigate the challenges they face.

A solution developed in New York that is gaining in popularity across the country is the naturally occurring retirement community, which provides a structure for seniors who have decided to stay in their homes instead of moving to an assisted living facility or other alternative.

Now, these NORCs are becoming more accessible than ever. A new Web site, NORCBlueprint.org, was launched last month by the founders of the original communities to reach funders, policy makers, program managers, and health care providers. It will outline NORC strategies, track the health care needs of senior citizens, and be a resource for groups such as the United Hospital Fund, which sponsors the site, to learn more about the needs of those “aging in place.”

“We were looking at how to connect NORC communities with health care providers, and also tracking people’s health in different areas to find out who are these seniors,” a spokesman for the United Hospital Fund, Bob de Luna, said. “The NORC Blueprint is a strategic effort to bring all these things together to make a difference for these seniors.”

In 1986, Fredda Vladeck founded the first NORC in Manhattan. There are now more than 80 publicly funded programs in 24 states, as well as many others supported by private donors. As the program grew, Ms. Vladeck was unclear how the NORC model would evolve outside of New York, especially as more NORCs began asking for guidance. So, with grants from the Daniels Fund, the New York-based nonprofit United Hospital Fund set out to create the NORC Blueprint.

“We wanted to create an extension of NORC nationally to help others around the country do what we’ve been doing,” Ms. Vladeck said. “The environment and the place are different, but the challenges are the same: the challenges of bringing together resources to make this a better place to grow old in.”

The Web site is set up to appeal to various users who are working with NORC programs. It uses case studies to illustrate how NORCs work and outlines a five-step program — focusing on areas such as community and sustainability — to help other communities develop NORC programs. It also includes strategies for funders and for the senior citizens themselves. Each page even has a resizing tool to increase the size of the text, in case any users are having trouble reading the information.

A wide range of experts helped develop the Web site, the senior program manager of the NORC Blueprint Project, Anya Nawrocky, said. Federal and local officials, policymakers, health care providers, and others were consulted in the process, which helped to make the program an all-encompassing resource.

“NORC is so unique because it will actually serve people of all income levels,” Ms. Nawrocky said. “When you think of an array of services, we tried to think of aging across the income spectrum.”

Although the Web site is set up to connect people to NORCs, it is not meant to solicit seniors to create a NORC. Many senior citizens don’t get their information from online sources, and most of them wouldn’t use the site to find and apply for benefits for themselves. Most of that kind of guidance is best spread by word of mouth and relationship-building.

“The Web site doesn’t take the place of good, quality relationships,” Ms. Vladeck said. “We are figuring out what uses of technology work best.”
