Supplementary Notes Research Study Title: Crash Testing HESCO Bastion Ltd Concertainers (HBLC) to U.S. State Department K-12 Name of Contacting Representative: Col. (ret) Jere Cook 16. Abstract The objective of this test is to determine if the HESCO Bastion Ltd. C-3315 flood barrier is capable of arresting a 6810 kg (15,000 lb) truck traveling at 80 km/h (50 mi/h) with 1.0 m (3.3 ft) of vehicle partial penetration and/or deflection. This criterion is based on Condition Designation K12 as stated in ST-STD-02.01, Revision A. This condition designation requires the HESCO Bastion Ltd. C-3315 flood barrier to withstand kinetic energy of 1,695,000 J (1,250,000 ft-lb). This report presents the construction details of the HESCO Bastion Ltd. C-3315 flood barrier, details of the vehicle used in the test, details of the test, and the assessment of the test results. Target impact speed was 75.0 km/h or above (47.0 to 56.9 mi/h), and the actual impact speed was 81.0 km/h (50.3 mi/h). The 1995 International 4700 single-unit flatbed truck impacted the barrier at 90 degrees, with the centerline of the vehicle aligned with the centerline of the barrier. The HESCO C-3315 barrier brought the vehicle to a complete stop with minimal penetration of the vehicle. The front of the cargo bed did not penetrate the inside edge of the barrier and came to rest 0.85 m (2.8 ft) from the inside edge of the barrier. ST-STD-02. 01, Revision A performance criteria limits penetration of the leading edge of the cargo bed to 1 m beyond the pre-impact, inside edge of the barrier. As stated above, the cargo bed did not penetrate the inside edge of the barrier. The actual impact speed was within the permissible range to receive the designated K12 condition level. According to the results of the full-scale crash test, the HESCO Bastion C-3315 flood barrier, as constructed in this test configuration, met the requirements for Condition Designation K12. 17.

  • Kopeopeo Canal Remediation Project Flood Management Plan Condition 7.1 Resource Consent 67173
    Kopeopeo Canal Remediation Project Flood Management Plan Condition 7.1 Resource Consent 67173 BOPRC ID: A2708898 MEMORANDUM To: Brendon Love Project Manager - Kopeopeo Canal Remediation From: Peter West B.E. (Hons), CPEng, MIPENZ Date: 28 September 2017 Contract Engineer File Ref: Objective Id: Subject: Kopeopeo East Canal Remediation Project; Flood Management Plan 1 Executive Summary Bay of Plenty Regional Council has received resource consent to remove and treat contaminated sediment from within the Kopeopeo East Canal (the Canal) by a wet-dredging method. This report primarily addresses the detailed conceptual flood-management and drainage aspects of the project specific to the proposed dredging method. It is intended that this report should provide a complete treatment of the relevant material, but in places to improve readability, reference has been made to our previous and/or supporting memoranda (references at the end). This report is in two parts: Part 1 discusses relevant aspects of flood management that form necessary background material, or that have not been previously addressed – either from changes in the proposed method; or from developments in supporting information as the project has unfolded. Part 2 forms the Flood Management Plan proper, with the necessary matrix of preparation, monitoring and response procedures and actions. This flood management plan and its supporting documents (see references below) fulfil the requirements of consent condition 7.1 including all items from 7.1a through 7.1g (Resource Consent 67173; 28 September 2016). This flood management plan is consistent with the Site Management Principles and the Flood Management Principles (reproduced below) that were identified in our January 2016 memo that now form the basis of the resource consent conditions relating to flood management.

  • Mosquito Creek Debris Flood Barrier – the First Line of Defence in Protecting the Public from Geohazards
    Mosquito Creek Debris Flood Barrier – The First Line of Defence in Protecting the Public from Geohazards Charles Hunt, M.Sc., P.Eng., ACSM., Jamie Stirling, M.Sc., P.Geo., Jack Price, EIT., ACSM Tetra Tech EBA, Vancouver, BC, Canada Fiona Dercole, Michelle Weston District of North Vancouver, North Vancouver, BC, Canada ABSTRACT In the District of North Vancouver, the Mosquito Creek watershed drains water from Grouse and Fromme Mountains through a densely populated residential area down to Burrard Inlet. The upper part of the watershed has had a number of landslides which have the potential to create debris floods, a significant geohazard to the residents of North Vancouver. The District of North Vancouver (DNV) requested the design and installation of a debris flood barrier at an optimal point on Mosquito Creek. Critical to this installation was careful sizing of the barrier for a 200-year debris flood event, locating the barrier within a fish bearing creek containing rare long tailed frogs and providing the most cost effective solution to the DNV. This paper presents the investigation of the mainstem of Mosquito Creek, including a detailed geohazard inventory map documenting notable features such as; significant sediment sources, natural barriers, landslides, bedrock canyons, waterfalls and debris jams. The paper also details some of the engineering design undertaken to construct the debris net within a bedrock canyon. The flexible net debris barrier at Mosquito Creek is only the second barrier of this type to be installed in British Columbia and when compared to alternatives is more cost effective, less intrusive and more easily repaired, making it a more sustainable solution.

  • Joint Emergency Action Plan for Severe Storm and Flood Response in City of San José
    Joint Emergency Action Plan for Severe Storm and Flood Response in City of San José Last Revised: December 2018 (THIS PAGE INTENTIONALLY LEFT BLANK) Joint Emergency Action Plan for Severe Storm and Flood Response in City of San José MC14104 December 2018 EXECUTIVE SUMMARY—JOINT EMERGENCY ACTION PLAN The first version of the Joint Emergency Action Plan for Severe Storm and Flood Response in City of San Jose (EAP) was approved by the Santa Clara Valley Water District (District) Board of Directors and San Jose City (City) Council at a joint meeting held on November 3, 2017. The EAP provided guidance on how the District and City would coordinate, communicate, and make decisions during storm and flood events and established a new method of classifying Flood Emergency Operational and Severity Levels. Since there was flooding on Coyote Creek in February of 2017, the EAP included an appendix of specific guidance related to Coyote Creek. The EAP is to be reviewed and/or exercised annually and updated/revised as appropriate. The District Board of Directors and San Jose City Council delegated approval authority for updates and revisions of the EAP to the City Manager and District Chief Executive Officer (CEO) or their designee. In addition to an annual review and revision of the EAP in 2018, three new appendices are being added to provide specific guidance related to flood risks on Guadalupe River, Canoas Creek and Ross Creek. The 2018 review and update to the EAP was initiated in April under the direction of a Joint Management Team and continues to be based on the concept of a Multi-Agency Coordination (MAC) Group.
