Saying he wanted to know "exactly where the problems are," Fairfax supervisor James M. Scott (D-Providence) asked to have the hiring practices of individual county agencies scrutinized as the Board of Supervisors this week received the first draft of an affirmative action plan.

Before its final adoption by the county, the plan, designed to eliminate discrimination in hiring, will be reviewed at several public hearings throughout the county.

Scott said he believes the county "has a long way to go" in getting rid of hiring discrimination, adding, "I'm talking about what the numbers show, very little has been accomplished."

The board staff was asked to summarize the monthly hiring reports required by the federal government for individual county agencies and report their findings to the supervisors.

Alan H. Magazine (D-Mason) said he hopes that the affirmative action will result in changes in the county's hiring policies but he voiced concern that the public hearings will raise young people's expectations about getting hired immediately.

Supervisor Warren I. Cikins (D-Mt. Vernon) reminded the board that the affirmative action plan should be made relevant not only in the hiring of blacks but also in hiring women.

In other action, the board announced plans to review the increase in rents and in tax assessments of rental property over the past few years in order to determine if the taxes paid by landlords have been in proportion to the rents paid by tenants.

The tax assessment and rent review was suggested by supervisor Audrey Moore (D-Annandale) who noted that in Prince George's County in the last 10 years there had been a 200 per cent rise in rents but only an 18 per cent rise in tax assessments.

Magazine suggested tht tenant advisory committees already set up in the county as well as the Landlord-Tenant Commission be invited to attend the public hearings when the board reviews the rents and tax assessments. The board asked that the review be held within the next 30 days.

The board also agreed to waive all building, electrical or plumbing fees for people installing solar heating systems in their homes as an incentive for home owners to use these energy-conserving systems. A home owner could save up to $60 in waived fees.
