This proposed culvert upgrade is necessary to alleviate the frequent backwater flooding on Onion Branch and the Hermitage Subdivision that is the result of existing culverts crossing under the Georgetown Railroad (Figure 1). The proposed improvements will provide conveyance of stormwater runoff for a design storm that is between a 2 -year and a 10 -year storm event based on economics and physical constraints related to the crossing. Runoff flow rates that exceed the design storm will still continue to overtop the Georgetown Railroad. Figure 1 Onion Branch Creek and Georgetown Railroad Crossing (looking downstream) The scope of this project includes the development of construction plans for the design of as many as 8 box culverts with associated channel improvements for transitioning. Espey Consultants, Inc. (EC) will solicit the support of subconsultants to provide survey and geotechnical services necessary to complete this project. I. Coordination with USACE and Notification — EC will coordinate and submit necessary documents to the USACE for compliance with Section 404 of the Clean Water Act. At this time it is anticipated that the activity will be covered under a "nationwide" permit and will not require an "individual" permit. A nationwide permit will require approximately 45 day review / approval time front the Corps. 2. Preparation of Construction Plans — Based on design criteria from the American Railway Engineering & Maintenance of Way Assoc., cost, input from the City of Round Rock and USACE, availability of materials, etc., EC will adjust the proposed design as necessary and develop construction plans of the proposed improvements. Construction plans will include appropriate general notes to contractor, erosion / sedimentation control measures, provisions for C:IDocuments and SettingslC0101Loca1 SettingslTemporary Internet FilesIOLK151contrnct anachments.doc April 2003 Culvert Upgrade on Onion Branch at the Georgetown Railroad Contract Agreement securing existing utilities (manholes, wastewater laterals, etc.), plan and profiles of the channel and box culverts, necessary cross - sections, details, etc. as required for construction by the contractor. EC will coordinate with the Georgetown railroad for "sign oft" of a phasing plan and construction documents. EC will prepare one draft set construction plans and one final mylar set of construction plans with incorporated draft comments. 3. Preparation of Bid Documents and Specifications — EC will prepare bid documents that will include contract documents and technical specifications using format and standard documents provided by the City of Round Rock. 4. Bid Phase Services (limited) — EC will prepare a master copy of the bid documents for reproduction at the CoRR's expense. EC will provide assistance at a pre -bid conference, the bid opening, and tabulating bids, and will make a recommendation of award following review of bid results. CORR will be primarily responsible for scheduling, conducting and holding meetings. 5. Water Pollution Abatement Plan — EC will prepare a water pollution abatement plan (WPAP) for submittal and review by the TCEQ. EC will work with the TCEQ and modify the WPAP as necessary for compliance with the Edwards Aquifer rules and approval by the TCEQ. The scope of the project does not include: 1. bid phase services; 2. utility adjustments or relocations; 3. significant channel improvements other than that necessary to transition back to the existing channel; 4. construction phase services; or 5. preparation of SW3P for compliance with TPDES.

Consider a resolution authorizing the Mayor to execute Supplemental Agreement No. 1 with Espey Consultants, Inc. for the study of Onion Branch stormwater drainage in the vicinity of The Hermitage. Resource: Tom Word, Chief of Public Works Operations Danny Halden, City Engineer History: The eastern edge of The Hermitage subdivision is within the 100 -year flood plain. Even though the houses in the subdivision are somewhat elevated and haven't experienced flooding, the streets will become inundated during intense rainfall events. An analysis of the area was recently performed under the original Professional services agreement approved by the Council on 9/26/02. The analysis indicates that houses in the area are relatively safe from flooding even during intense rainfall events. This Supplemental Agreement will provide engineering services to design culvert improvements to decrease the frequency in which streets in the area are inundated. Funding: Cost: $39,150 Source of funds: Regional Stormwater Detention Program Outside Resources: Espey Consultants, Inc. Impact /Benefit: Design of culverts to reduce frequency of flood inundation of Hermitage Drive.
