Respectfully submitted, John Powell Public Works Director/City Engineer Page 4 of 53 WATER BOARD AGENDA MEMO To: Water Board, City Administrator From: John Powell, Public Works Director Department: Engineering Subject: Well 5 Retaining Wall Meeting: Water Board - Aug 24 2023 INTRODUCTION: The retaining wall along the northeast side of the Well 5 driveway is failing and in need of repair. As this is the second time the retaining wall has had to be repaired, the Water Board directed staff to consider additional options before making the repairs. DISCUSSION: Well 5 was constructed in 1999. As part of the project a Modular Block Wall (MBW), about 4 feet tall and 117 feet in length, was constructed between the Well 5 driveway and the boulevard of English Avenue. In 2008, a significant segment of the retaining w all near the Well 5 building was repaired. Another 85-foot section of the wall has failed. A preliminary cost estimate using the same MBW materials indicated that the repairs could cost as much as $80,000. At the January, 2023 meeting, the Water Board directed staff to consider additional options for the wall repair. TKDA was retained to review repair options; their report is attached. Per the report “One option considered and discounted was rebuilding the existing wall with similar materials. The disadvantage of this option is that the failure will likely occur again. There is no evidence of drain tile below the wall and the limestone backfill may be insufficient to handle additional loading due to any potential water behind the wall.” The recommended option is complete replacement of the retaining wall with Prefabricated Modular Block Wall materials. Prefabricated Modular Block Wall materials are made from placing concrete in a mold and curing in the mold. This is a different process than used fo r MBW materials. BUDGET IMPACT: As noted in the TKDA report, the estimated construction cost for a replacement wall is $164,000, which includes a 20% construction contingency. Also attached is a scope and budget for preparation of construction plans and specifications, and bidding assistance; the estimated cost is $16,400. ACTION REQUESTED: Receive the report and proceed with the design and construction of a replacement Well 5 retaining wall using Prefabricated Modular Block Wall materials as recommended.

The wall is 117 feet long. The wall was built with dry cast concrete blocks with a geogrid between layers and clear limestone rock backfill. The wall varies in exposed height from 0 feet to 4 feet tall. Existing plans of the wall were not available. Field measurements were taken on stable portions of the wall to determine the original design batter dimensions. The field measurements on portions of the wall that showed no signs of deterioration indicate that the front face of the wall was to be battered at 0.75” horizontally per 8” of block height. A 4” tall top block was used for the length of the wall and was set 1.5” forward from the front face of the topmost block. Figure 1 – Location of Pumping Station Retaining Wall Page 12 of 53 Page 2 2023 Wall Evaluation Pumping Station Retaining Wall 1.1 Wall Evaluation Findings A visual inspection of the wall was performed on June 30th, 2023. The general wall layout can be seen in Figure 2. Measurements were taken at the top of the wall to determine how much the top of wall was set back or battered from the face of the wall at the ground line. Batter measurements are tabulated below in Table 1. These batter measurements were compared to calculated batter values according to measurements taken at the South end of the wall, where no signs of failure were observed. The planned batter measurements will be compared to the field batter measurements to determine locations of potential failure along the length of the wall.

This batter was assumed to be the planned batter for the entire length of the wall. The planned batter also includes a 1.5” forward set of the top block, which is 4” tall. (2) Negative value indicates top of wall is tipping forward relative to base of wall at ground line. (3) Wall has completely failed from STA 0+91 to 1+09. Page 14 of 53 Page 4 2023 Wall Evaluation Pumping Station Retaining Wall At almost all locations that measurements were taken along the wall, the batter measured is less than the anticipated batter. This indicates that the wall has tipped forward at these locations or it was improperly constructed. Between station 0+91 and 1+09, the wall has already failed, which can be seen in Figure 3. Figure 3 – Station 0+91 to 1+09 Failure The location of the failure corresponds to where vehicles likely drive and/or park on the driveway for the pumping station building above the wall. It is possible that the wall was not designed to withstand the live loads that are associated with vehicular traffic thus resulting in the failure and the wall tipping forward at numerous locations. Poor drainage behind the wall may also contribute to failure and tipping forward. The presence of water behind the wall will add additional horizontal pressure on the wall. The clear limestone backfill does help to drain the wall, but if there is no drain tile at the base of the wall the water has no place to go and it will sit within the voids of the clear limestone. Page 15 of 53 2023 Wall Evaluation Pumping Station Retaining Wall 1.2 Cost Estimate and Wall Recommendations Given the existing wall has already failed over a length of 18 feet, it is not recommended to repair the wall. The following recommendation would require an investigation into the utilities present under and around the wall. There is a catch basin about 250 feet north of the wall on English Avenue that would likely be used as a tie in point for the drainage system of the wall. The use of this catch basin as a tie in point would need to be investigated as well. 1.2.1 Option 1 - Prefabricated Modular Block Wall (PMBW) Prefabricated Modular Block Wall (PMBW) have been around for a very long time and can be built very efficiently when the exposed height of the wall is kept below 8 feet. When PMBW walls are installed at exposed heights greater than 8 feet they require soil reinforcement to be installed behind the wall. This increases the excavations required for the wall as the soil reinforcement typically goes behind the wall a considerable ways. At this location, the wall could be kept under the 8 feet height to keep an efficient design and construction. In addition, the front face of the PMBW could be installed about 8 feet farther forward (towards the street) from the face of the existing wall. This would allow the wall to be further from the parking/driving area and reduce the additional live load on the wall. This location would also allow for the new wall to remain under 8 feet tall, which would avoid the need for any geogrid reinforcement. PMBW’s have near level fill on the top of the wall, which would not be a problem, given the existing driveway on top of the wall. The existing curb and a portion of the pavement (up to approximately 5 feet from the curb) would be removed and replaced due to the existing settlement and deterioration due to the current failed wall condition. With the wall being set 8 feet forward from the existing wall, a fence could be used at the edge of the existing parking/driving area to keep vehicular loading further from the wall. This would keep both vehicular loading away from the wall and provide a safety barrier to reduce falling risks. It may be necessary to install temporary shoring between the existing wall and the well building to protect from undermining during installation of the new wall. The shortest distance between the building and the back face of the existing wall is 5.5 feet, leaving sufficient room for the temporary shoring. Refer to Exhibit A for a schematic of this option.

Does not include any costs for temporary easement or relocation of existing utilities. 1.2.2 Option 2 - Increase Slope from Back of Curb Leaving the wall in its current location, the slope from the back of curb to the front face of the wall could be increased to shorten or eliminate the wall. When the wall cannot be eliminated in these areas a PMBW wall would be recommended at these locations of similar design to Option 1 above. For this report TKDA assumed a maximum slope of 1V:3H in front of the wall at two cross sections from available survey information. At both locations the wall could not be eliminated, but it could be shortened to a wall height significantly less than 8 feet. Refer to Exhibit A for a schematic of this option. Page 17 of 53 2023 Wall Evaluation Pumping Station Retaining Wall 1.2.3 Consideration of Options Other Options One option considered and discounted was rebuilding the existing wall with similar materials. The disadvantage of this option is that the failure will likely occur again. There is no evidence of drain tile below the wall and the limestone backfill may be insufficient to handle additional loading due to any potential water behind the wall. The location of the curb behind the wall also indicates the wall sees additional loading due to live load surcharge, which could contribute to the failure again if it were re-built with similar materials. Another disadvantage of small block retaining walls is that they cannot go as high without proper reinforcement. Typical reinforcement methods use geogrid, which anchor the soil back behind the wall. If the wall were to be pushed out to avoid additional live load surcharge it is likely that reinforcement would be needed and require additional excavations, including removal of a large portion of the parking area, to rebuild the wall with small blocks. Option 1 PMBW walls are contractor designed walls that require special provisions in the form of a performance specification. These walls require near level fills on top of the wall. As there currently is an existing parking/driving area on top of the existing wall, a level fill on top of the wall can be maintained. A fence could be used to ensure that vehicular traffic stays further away from the wall than it currently does. The sprinkler box near the front face of the wall and the fiber vault to the north of the wall will need to be investigated in case any utility relocation is required. The front face of PMBW walls can also have an aesthetic treatment, though the range of aesthetics can be limiting. The wall can be painted with any desired color of special surface finish. Option 2 Keeping the wall in its current location and increasing the fill slope from the back of curb to the front face of the wall would still be most effective with a PMBW wall of shorter height and length. Therefore, the benefits of the PMBW wall listed above still apply. Although this option provides the least cost there are still some drawbacks. There will be a much steeper slope in front of the wall and if a shorter PMBW wall is still required it will be adjacent to the parking/driving area. TKDA recommends that Option 2 be investigated first to determine if the wall can be eliminated or wall height reduced. If the wall cannot be eliminated, it may be best to determine if a combination of Option 1 and 2 can be used. If the wall can be pushed forward and the slope on front of the wall steepened a shorter PMBW wall can be used and there will be a “buffer” zone between the back face of the wall and driving/parking area. A combination of Options 1 and 2 may prove to be a more economical solution than Option 1 alone. In any case, the impacts to the existing utilities will need to be considered in all options. A geotechnical engineer must be retained in either option for the following needs at a minimum: · Analyze foundation soils o Determine Foundation Types and Requirements · Determine backfill requirements · Investigate the vibration impacts on the existing wall and adjacent building during footing excavations · Provide general geotechnical recommendations consistent with a wall investigation/construction Page 18 of 53 0+00 0+68.4 7 0+00 0+64.84 A A B B SECTION A-A 965 970 975 980 965 970 975 980 0+00 0+50 0+85 SECTION B-B 965 970 975 980 965 970 975 980 0+00 0+50 0+75 STA:0+00.00 ELEV:970.66 STA:0+19.14 ELEV:970.33 STA:0+23.55 ELEV:970.27 STA:0+27.38 ELEV:966.28 STA:0+49.84 ELEV:961.19 STA:0+07.67 ELEV:971.10 STA:0+23.63 ELEV:971.06 STA:0+24.42 ELEV:967.00 STA:0+43.16 ELEV:962.42 CURB CURB TOP WALL BOTTOM WALL CURB CURB TOP WALL BOTTOM WALL K: \ a - f \ F a r m i n g t o n \ 2 0 7 5 1 0 0 0 \ 0 4 _ P r o d u c t i o n \ 0 1 _ C A D \ 0 3 _ C o n c e p t s \ C - S E C T I O N S . d w g J u l 3 1 , 2 0 2 3 - 5 : 0 0 p m DESCRIPTION OF REVISIONSNO.DATE BY DESIGNED DRAWN CHECKED DRAWING NO.
