Civic Involvement is too broad a request. My bank would get so many memberships on the PTA, or booster clubs for cheerleaders, future farmers of America - that sort of involvement, the kind that does not meet the definition of community development.
An addition to your form to provide better info to the examiners might be a question to the staff asking them to explain why this activity meets the definition of community development under the CRA. Or what info is being relied upon to make the determination that the activity is CRA eligible as a community service.
