NIWOT — As the holidays approach, Community Food Share and other local nonprofit groups hope to tap into your charitable giving side.

Niwot-based Community Food Share wants donors to participate in its "1 Resident, $1, $1 Million" challenge to raise money for a new building in Louisville. The idea is that if each resident in Boulder and Broomfield counties contributed just $1 to the capital fundraising campaign, the group would reach its goal to raise $1 million to help buy the building.

An anonymous benefactor has pledged an additional $2.5 million to Community Food Share at the end of the year if the food bank raises $1 million by then. The nonprofit has $375,000 left to raise.

The group's annual "Let's Bag Hunger" campaign also wraps up this week. Tom Reed, Community Food Share's food procurement manager, said the group hopes to collect as much food as last year – just under 102,000 pounds. That's well short of the group's goal to collect 120,000 pounds of food donations though. Wednesday is the last day to donate food.

At the same time, the Community First Foundation in Arvada is gearing up for Colorado Gives Day on Tuesday, Dec. 4. Community First helps donors give money to local charities through its online website GivingFirst.org. FirstBank Holding Co., based in Lakewood, has committed $600,000 to the 2012 campaign. Locally, FirstBank has nine locations in the Boulder area.

Boulder Valley residents and companies gave close to $1 million to local charities for Colorado Gives Day last year. In total, the campaign raised $12 million for 900 charities across the state in 2011.

In Boulder County, 5,426 people made $942,145 in donations to 97 local charities, according to statistics from Community First. The amount represented a 156 percent increase in donations through Colorado Gives Day more than the 2010, according to statistics.

Broomfield County saw 297 donors give $41,509 to eight charities. The amount represented a 24 percent increase in giving from the year before.

In all, Boulder County donors made $1,087,325 in 6,415 donations to their favorite charities in the county and around the state. Broomfield County donors gave $91,308 in 650 donations to charities.

In 2011, the Colorado Gives "day" actually ran for 36 hours because of a computer glitch. High traffic from donors disrupted the group's website.

Donations ranged from $10 to $500,000, with almost half of all donations made were either $50 or $100, the foundation said. Processing fees were covered by Community First Foundation, FirstBank and 10 other foundations, meaning that 100 percent of the donations went directly to the participating nonprofit groups, the foundation said.
