Allensworth said it didn't "seem to fit the overall pattern of extension of town services" because development there would get sewer and water service from Hagerstown not Funkstown.
He said he also had concerns about the effect of development on the town road and bridge.
Kuczynski said the rationale was that residential building on the property would add to the town's tax base.
Funkstown Planning Commissioner George Wheelock said he didn't think development on the property would substantially affect traffic through town.
It's development around Funkstown that's increasing traffic through the town, said Wheelock, who said planning commissioners were mainly concerned with how annexing the land would affect plans to build a bypass through it.
Planning Commission Chairman Doug Stone said the commission had no problems with the annexation proposal as long as the bypass plans weren't affected.
Stone said the commission wasn't clear on the bypass route based on the annexation maps it had seen.
The planned bypass route hasn't changed, Crampton said.
Crampton has said his immediate plans are to build a house for his family on the 43.6-acre property, bordering the town's western boundary across Antietam Creek.
He said he has made no plans for developing the rest of the land, primarily zoned suburban residential with a few acres along Oak Ridge Drive zoned neighborhood commercial.
The 23.8-acre tract of parkland is east of the town limits, adjacent to Funkstown Community Park. It was purchased with a grant from the state's Program Open Space.
The county zoning for the property is suburban residential and agriculture, but the Open Space grant was awarded on condition the land not be developed.
The annexation will go into effect on Oct. 4 after the proper papers are filed and the town charter is amended to describe the new boundaries, Kuczynski said.
