The Lake Oswego Indoor Tennis Center, located at 2900 Diane Drive in Springbrook Park, offers four indoor courts and is open year round for public use. LOITC is a 4 court indoor tennis center with 19 parking spaces. The facility was built in 1975 at a cost of $335,000. The City‘s Charter prohibits development of any kind in SpringbrookPark which limits the expansion of the existing tennis facilities at its current location. The facility is available for all ages and abilities, and provides a variety of recreational opportunities. These activities help build confidence, reinforce self-esteem and encourage socialization.

Throughout the year, Parks & Recreation offers tennis lessons for players of all abilities, ages four and up. Special activities include City League and USTA play, competitive and social ladders, Jr. Aces, a summer youth program, junior development/match play opportunities, Special Olympics, and daily court play.

structural Consultant Report - KPFF

• Building Description

• The tennis center is a pre-manufactured metal building made by Varco Pruden as evidenced by the VP symbol on the ridge of the building. The original design drawings were made available for review and are dated 1974.

• Current Condition

• A walk through of the building did not show any obvious signs of distress in

• the metal building frame. It appears that the roof does have some minor wind damage and may require some maintenance. Additionally it appeared that the gutter on the back side of the building was likely clogged and should be cleared to ensure that leaking does not occur on the interior of the building.

• Seismic Resisting Lateral System

• The lateral resisting system consists of X-braced tie rods in the long direction and steel frames in the short direction. Current code level seismic forces are higher than those the building was designed for in 1974. The building weight is light enough that it is possible wind loads would control the lateral design of the building, but the building would not meet current code prescribed seismic forces.

• Recommendations

• A seismic hazards investigation should be performed to assess the seismic condition of the building and recommend seismic improvements to the building as required.
