LAFAYETTE -- Peak to Peak Charter School was granted the city's approval to rezone the land it bought, allowing the school to add a second access road, new parking lot and new sports fields.

The City Council voted unanimously Tuesday night to approve the zoning changes. Peak to Peak still needs design approval before constructing the planned baseball fields.

"We need to work with what's been proposed and make it the best we can," said City Council member Alex Schatz.

Several neighbors of the 1,400-student school complained Tuesday about the traffic and cars parked on their streets, urging the council to vote against the zoning change. Noise and light pollution also were concerns.

"We all believe this project will only compound problems and add new ones," said neighbor Paul Resch. "Do not allow Peak to Peak to get by with the minimum, with no responsibility to the neighborhood."

Boulder Valley school board members last year agreed to sell the 8.9-acre parcel of land to Peak to Peak. The land, which cost Peak to Peak $550,000, sits next to the charter school at 800 Merlin Drive in Lafayette.

The land mainly will be used for two regulation baseball fields. But the first priority, officials said, is building a second access road off Emma Street and a new, 84-space parking lot -- improving traffic flow.

"We seriously want to be a good neighbor," said Peak to Peak parent Rich Bradfield.
