SUBJECT:
A Resolution to award the Rosedale, Liberty, and Sans Souci Storm Sewer Extensions project to H. Linden & Sons Sewer and Water, Inc., 722 E. South St., Unit D, Plano, IL 60545 located in Wards 5 & 7.
PURPOSE:
To extend storm sewer at three locations to address localized drainage issues at those locations. Location map is included as Exhibit A.
BACKGROUND:
These three locations were brought to the Engineering Division's attention by residents with drainage concerns. Two of the locations, Rosedale Avenue South of W. Illinois Avenue and the Sans Souci Drive Cul-de-Sac just east of Orchard Road are located in Ward 5. The first location occurs at the two south inlets at the Rosedale Avenue and W. Illinois Avenue intersection which receive over 13 acres of tributary flow from as far south as Plum Street. The existing storm sewer on the south side of W. Illinois Avenue is shallow, so constructing new 12" storm sewer 330' south to the Lilac Court is the feasible limit of this extension. Additional inlets with high capacity grates will also be added on the south side of the W. Illinois Avenue intersection to prevent the grates from clogging with tree debris and to prevent ponding at the south intersection radii.
The second Ward 5 location is the Sans Souci Drive Cul-de-Sac. The property owners at 2350, 2360, and 2370 Sans Souci Drive have experienced more frequent ponding along the rear and side yard property lines in recent years. These homeowners have committed to installing storm sewer on their properties and require a storm sewer structure in the R.O.W. at the front of their property to connect to. The curb slope at the proposed structure location is relatively flat and experiences ponding in the curb which can be seen in the condition of the pavement. This additional structure will also improve the drainage of the street.
The third drainage issue is located in Ward 7 on the south side of Liberty Street in front of the 2375 Liberty Street property approximately 1,100 feet west of the Asbury Street intersection. Groundwater appears to be surfacing in the curb line east of the 2375 Liberty Street driveway and this nuisance flow is causing a hazardous condition of ice buildup during freezing conditions that needs to be eliminated. Perforated storm sewer is proposed to be installed under the curb and gutter along with an infiltration catch basin in order to intercept the groundwater flow preventing it from surfacing. All three proposed storm sewer extensions will provide benefits to each neighborhood.
DISCUSSION:
The project is budgeted for in 2019 within accounts 280-1852-512-81-01(B010, Entire $200,000.00 budget to be utilized pending City Council approval) and 280-1852-512-81-23 (B037, $13,321.00 of $400,000.00 budget for storm sewer extensions) which will cover the low bid cost of $213,321.00 as attached. The proposed improvements have been publicly advertised and bid in conformance with City procedures. The advertisement for bid is attached as Exhibit B. Six conforming bids were received, publicly opened and read aloud on June 27, 2019. This contract is subject to the local vendor preference ordinance. However, none of the contractors submitting bids were eligible according to the requirements listed in the ordinance. The low bidder, H. Linden & Sons, has successfully completed similar projects for the City in the past. The bid tabulation and H. Linden & Sons's bid are attached as exhibits C and D.
IMPACT STATEMENT:
These three locations will experience minor traffic impacts during construction of the improvements.
RECOMMENDATIONS:
I request the proposed resolution be adopted.
