TO: THE CITY CCUNCIL FROM: THE CITY MANAGERS OFFICE SUBJECT: COU\CIL C0ADIUNICATIOt` AUTHORIZE DEMOLITION OF HALE PARK RECREATION BUILDING October 21, 1987 PREPARED BY: City Manager RECOMMENDED ACTION: That the City Council order the demolition of the Hale Park Recreation Building and direct staff to initiate the proceedings. BACKGROUND INFORMATION: At the regular meeting of September 16, 1987, the City Council was advised that the Hale Park Recreation Building had been closed following a routine inspection which revealed the possibility of serious structural deficiencies. An inspection by a licensed structural engineer was ordered and the results of his inspection are summarized in the attached report (Exhibit A) previously distributed to the City Council. The staff has met on this matter to discuss the removal of certain equipment which can be used elsewhere in other City facilities and everything which fits that category will be removed prior to the demolition. The bulk of the activities previously held in this facility have been relocated to Hutchins Street Square. Respectfully submitted, Thomas A. Peterson City. Manager TA":br Attachment TXTA.07A COUNC269 MEMORANDUM TO: The Honorable Mayor and Members of the City Council FROM: City Manager DATE: October 2, 1987 SU6J: Hale Park Recreation Center Approximately three weeks ago during a routine inspection of the !sale Park Recreation Center prior to repainting the structure, it was determined that there was sufficient reason to temporarily close the building in the interest of public safety, pending receipt of a structural engineer's evaluation and report. The building has remained closed since that date and events booked for this facility have been relocated. We have received that report, a :opy of which is attached. The City Council's attention is directed to the conclusions on page 3. The bottom line is that the structural"' engineer hired to perform this evaluation has deemed the building to be unsafe for occupancy. As the building now stands, the firm concludes, it is a public hazard. The staff will initiate the procedures leading to the demolition of this building next week. We will keep the City Council apprised. TAP:br Attachment TXTA.07A COUNC266 GAMAYO, SANCH EZ & ASSOCIATES, INC.

There are small classrooms and storage rooms around this building As you requested, representatives of our firm inspected the Hale Park Recreation Center on East Locust St. in Lodi, CA on September 21, 1967. The building has been closed to the public due to bowing of the roof trusses. The purpose of our inspection was to investigate the trusses and to evaluate the integrity of the building for both gravity and lateral loads.

STRUCTURAL ENGINEERS ASSOCIATION OF CALIFORNIA GENERAL The main portion of the building is a large room, approximately 110' long and 64' wide, with a narrow mezzanine walkway, on three sides. There are small classrooms and storage rooms around this building on all sides. The main roof framing consists 'of ix straight sheathing spanning to 2x4 ra.- -rs @ 30" o.c. which are supported by 4x10 purlins @ 8' o.c. spanning 16' between wood trusses. These trusses were constructed using the following: 4- 2x8 mambers for the top chords 4- 2x10 members for the bottom chords steel rods of varying diameter for the vertical webs 2x8 members for typical diagonal webs a,. 4x8 members for the diagonal webs at midspan" There is a line of x -bracing at the second panel point from each end of the trusses. '. The lower surrounding portion of the roof consists of lx sheathing i Registered as Civil and/or Structural Engineers in: California. Nevada, Oregon, Wyoming• Hawaii, Washington, Colorado.

Oc'ober 11, 198 STRUCTURAL 3 CML ENG;NEERS CONSULTANTS Pace 2 with 2x4 rafters @ 30" o.c. and 2x4 ceiling joists @ 24" o.c. It appears the building has been re -roofed more than once as several layers of roofing are visible on both the upper and lower roof areas. UPPER ROOF AREA There is a pronounced bowing of the upper roof area which is easily visible from the outside. The south exterior wall is seen to be bowed laterally outward and the north wall has bowed inward. The cause of this movement is the slenderness of the top chords of the trusses and the lack of a proper diaphraom to keep the compression side of the truss in alignment. The 4- 2x8 members are not connected in a manner which would enable them to act as one integral chord and, thus, must be considered to be 4 separate members. The resulting slenderness problems have caused the top chord to buckle between the end of the truss and the line of x -bracing. The bucked chord is approximately 8" from its original position. The line of x -bracing has apparently prevented further movement but has pulled out in many locations and may no longer be effective. In the second truss from the south wall, at the second panei point from the end, the top chord has shifted laterally by 1" from its original location relative to the intersecting diagonal web, causing an eccentric connection condition at this point. The 2x8 diagonal webs have a slenderness factor, L/d, greater than 50 and would not be acceptable by today's standards. These members are overstressed by up to 174% for total loads and up to 5070 for dead loads alone. The multiple layers of roofing further aggravate this condition. There are numerous water stains on the ceiling, indicating severe roof leakage at some time in the past. it could not be ascertained whether or not these leaks have been repaired. The 1x sheathing has been replaced in a small area on the north side of the building, possibly in response to dry rot resulting from this leakage. LOW ROOF.AREA The 2x4 rafters are overstressed by 48% for dead + live loads and exhibited excessive deflections even for dead load alone. The 2x4 hip rafters at the building corners are highly overstressed for dead loads alone, and were seen to have high deflections under existing load Hale Pa ­ Center October 1 1987 Page 3 conditions. GAMAYO. SANCHEZ L ASSOCIATES, INC. STRUCTURAL E CIVIL ENGINEERS . CONSULTANTS There is a considerable amount of dry rotting evident in both the sheathing and rafters. particularly at the overhangs. In one location, on the East side, there is a 6" diameter hole which has penetrated the sheathing completely. RESISTANCE TO LATERAL LOADS Having been built in the 1920's. the building was apparently not designed to resist wind or seismic for,:es as there is no reliable lateral force resisting system. The roof r.nd floor sheathing cannot act as lateral load diaphragms because there arc no connections enabling them to do so; and, the end wall studs ora not even properly connected to the roof system. CONCLUSIONS , Based on the severe bowing of the roof framing and the lack of a lateral load resisting system, it is our professional opinion that the building is unsafe for occupancy. It should be noted that the deficiencies described in this report resu.Ited from a brief inspection. A more thorough inspection may well reveal more problem areas. We believe the building has surpassed its useful life. O attempt to upgrade or renovate it would be neither practical nor economically feasible and may, indeed, prove to be* impossible. Thus, our recommenda- tion would be to demolish the building as soon as possible. As It now stands, it is a public hazard. Respectfully submitted, ustin C.
