Cross drainage structures - Cross drainage structures convey storm drainage flows from one side of the street to the other and normally consist of storm drains or culverts. Design Rainstorm - A rainfall event, defined by storm frequency and storm duration, that is used to design drainage structures or conveyance systems. Detention Basin - An impoundment structure designed to reduce peak runoff flow rates by retaining a portion of the runoff during periods of peak flow and then releasing the runoff at lower flow rates. HEC-HMS - A Hydrologic Modeling System developed by the U.S. Army Corps of Engineers. Initial storm drainage system - The drainage system which provides for conveyance of the storm runoff from minor storm events. The initial drainage system usually consists of curb and gutter, storm drains, and local detention facilities. The initial drainage system should be designed to reduce street maintenance, control nuisance flooding, help create an orderly urban system, and provide convenience to urban residents. Major storm drainage system - The drainage system that provides protection from flooding of homes during a major storm event. The major storm drainage system may include streets (including overtopping the curb onto the park strip and sidewalk), large conduits, open channels, and regional detention facilities. Major storm event - Generally accepted as the 100-year storm. Homes should typically be protected from flooding in storm events up to a 100-year event. Minor storm event - Storm event which is less than or equal to a 10-year storm. Probable Maximum Flood - A flood event with a very low probability, usually less than 0.2%, of being exceeded in any given year. This flood event is used as a design storm when failure of the structure could cause loss of life. Retention Basin - An impoundment structure designed to contain all of the runoff from a design storm event. Retention basins usually contain the runoff until it evaporates or infiltrates into the ground. Storm Duration - The length of time that defines the rainfall depth or intensity for a given frequency. Storm Frequency - A measure of the relative risk that the precipitation depth for a particular design storm will be equaled or exceeded in any given year. This risk is usually expressed in years. For example, a storm with a 100-year frequency will have a 1% chance of being equaled or exceeded in a given year. ---PAGE BREAK--- v Murray City Storm Drainage Master Plan Update ABBREVIATIONS cfs cubic feet per second (ft3/s) E East ft foot or feet GIS Geographic Information System HAL Hansen, Allen & Luce, Inc.

(HAL) in June 2000. This master plan update report addresses existing and future storm drainage needs of Murray City and includes an area which was annexed after the master plan was completed in 2000. Most of Murray City has been developed, but plans to redevelop parts of the City exist. Therefore, this master plan update identifies deficiencies due to development since the 2000 Master Plan, deficiencies previously identified in the 2000 Master Plan, existing deficiencies in the annexed area, and projected deficiencies due to planned future development. Existing and future deficiencies are identified and the preferred solution alternatives are presented with cost estimates. A capital improvements plan is developed for the master plan update projects. Murray City’s storm drainage master plan update serves four purposes: 1. Provide storm water runoff models which predict how the storm drainage system responds to design storm runoff events 2. Identify and describe existing system problems 3. Identify alternative mitigation measures to eliminate flooding during design storm runoff events 4. Provide a capital improvement plan implementing the preferred drainage solutions Storm water models were prepared for the 2000 Master Plan using the U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center Model (HEC-1). As part of the storm drainage master plan update, HAL translated the HEC-1 models to the updated USACE model Hydrologic Engineering Center Hydrologic Modeling System (HEC-HMS) which was selected as the storm drainage model for computing the storm runoff hydrographs. ArcGIS 9.2 Geographic Information System (GIS) by Environmental Systems Research Institute (ESRI) was used as a spatial reference tool for development of the HEC-HMS models. The models, in conjunction with the GIS data, will help the City to continue to update and analyze the system for potential drainage deficiencies and facilitate the analysis and design of mitigation measures. BACKGROUND Murray City is located in the central region of Salt Lake County near the intersection of Interstate Highway 15 and Interstate Highway 215. Murray City has expanded a number of times over the past 100 years and recently annexed nearly 1,500 acres into the City boundaries. Most of the annexation stretches to the East, extending the City boundaries to the Van Winkle Expressway (Hwy 152). The annexed area contains storm drainage systems, but has not been analyzed recently. The annexed area also includes some old irrigation lines used for storm drainage. In addition, Murray City has experienced development and existing storm drainage system changes since the last comprehensive storm drainage master plan was completed in June 2000. Consequently, the City desires a plan that addresses existing storm drainage problems, and necessary infrastructure to support future development. Murray City covers about 7800 acres and has an elevation change of approximately 230 feet from 4232 to 4462 above mean sea level (Figure I-1). The natural drainages of the study area are the Jordan River, Little Cottonwood Creek, and Big Cottonwood Creek. Both of the Cottonwood Creeks flow northwest and join the Jordan River in the northwest region of the City. ---PAGE BREAK--- Salt Lake County North East South West Northeast Central South Central Southeast Central East Central West Northwest 3900 S HIGHLAND DR HIGHLAND DR HIGHLAND DR 4500 S 1300 E 900 E STATE ST I-15 SB FWY I-15 NB FWY REDWOOD RD 5900 S 5400 S VINE ST I-215E EB FWY 4800 S I-215E WB FWY I-215E SB FWY I-215E NB FWY I-215W SB FWY 700 E 7200 S 7000 S 5300 S 6400 S I-215W EB FWY I-215W WB FWY 4700 S 6200 S VANWINKLE EXPY WASATCH BLVD TAYLORSVILLE EXPY HUSKY HWY VINE ST Murray Holladay Taylorsville Midvale Cottonwood Heights West Jordan West Valley City South Salt Lake Sandy Sandy JORD A N RIVE R N O R T H JO R DAN C ANA L EAS T CA N A L J O RDAN A N D S LC C ANAL LITT LE C O TTO N WOOD CR E E K BIG CO T T ONWO O D CREEK B R I GH T ON C A N AL SO U T H J O R D AN C A NAL MURRAY CITY STORM DRAINAGE MASTER PLAN UPDATE FULL STUDY AREA FIGURE I-1 0 6,000 12,000 3,000 Feet ¦ LEGEND City Boundaries Rivers and Canals ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update I-2 The Jordan River flows north along the west side of Murray City. The East Canal and Jordan and Salt Lake City Canal cut across the southeast corner of the City and flow to the northeast (Figure I-1). Storm water runoff is a difficult resource to manage. Unlike sanitary sewers and culinary water systems, there are no clearly defined minimum service requirements for storm water systems. Storm water flows are dependent on many complex time and spatially varied factors. Even a natural undeveloped drainage system is not static. Streams can erode in one section while depositing in another. Stream courses can also change alignment and cross section dramatically with just one storm runoff event. Urbanization compounds the problem and creates a need for a drainage system with the basic goals of managing nuisance water, protecting development from damage, and protecting waters from adverse quality and quantity impacts. SCOPE The scope of the storm drainage master plan update includes the following: 1. Review of existing storm drain facility mapping and information. 2. Translation of the HEC-1 storm drainage models prepared for the 2000 Master Plan to HEC-HMS and an update of the models reflecting existing conditions. 3. Evaluation of the existing storm drainage facilities and identification of deficiencies. 4. Development of the preferred storm drainage plan including recommendations for immediate and future improvements. AUTHORIZATION In June 2010, Murray City selected Hansen, Allen & Luce, Inc. (HAL) to assist them in updating the master plan of the City’s storm drainage system. Development of the storm drainage master plan update was completed under the direction of, and in cooperation with City staff. STUDY AREA The complete master plan update study area includes area within Murray City boundaries and drainages tributary to areas of the City. The northern boundary of the study area reaches 3900 South. The southern boundary extends into Midvale City as far as 7200 South (Figure I-1). The western boundary of the study follows along Murray City’s western boundary. The eastern boundary of the study extends into part of Holladay City as far as Highland Drive and includes parts of Salt Lake County in between Murray City and Holladay City. ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update II-1 CHAPTER II HYDROLOGY This section describes the hydrologic analysis that was performed for the study area, which includes a discussion of 1) the frequency and duration of the design storm used in the analysis, 2) updating and development of drainage basin characteristics, and 3) the methodology and process behind the storm drainage models. DESIGN STORM Drainage Design Frequency The approach selected by Murray City for determining the drainage design frequency is based upon methodology given in the Urban Storm Drainage Criteria Manual (Denver Regional Council of Governments, 2001). This manual defines the urban drainage system as follows: "Every urban area has two separate and distinct drainage systems, whether or not they are actually planned for and designed. One is the initial system, and the other is the major system. To provide for an orderly urban growth, reduce costs to future generations, and obviate loss of life and major property damage, both systems must be planned and properly engineered." The initial storm drainage system is sometimes referred to as the convenience system in that it is designed to "reduce street maintenance costs, to provide protection against regularly recurring damage from storm runoff (of a 10-year recurrence interval or less), to help create an orderly urban system, and to provide convenience to the urban residents" (Denver Regional Council of Governments, 2001). Storm sewer systems are generally considered part of the initial storm drainage system. In conjunction with the initial storm drainage system, provisions should be made to avoid major property damage or loss of life from a major storm runoff event. Such provisions are considered to comprise the major storm drainage system. Please refer to Figure II-1 which identifies the initial and major storm drainage systems described in the Urban Storm Drainage Criteria Manual. The major storm drainage system in newly developing urban areas or business districts should generally be designed for the 100-year event with the objective to eliminate major damage to edifices (homes, buildings, etc.) and to prevent loss of life. This does not mean that storm sewers (which are considered part of the initial storm drainage system) should be designed for the 100-year event. It means that the combination of storm sewers and channelized surface flow as part of a 100-year channel should be designed to accommodate the 100-year event. There appears to be general agreement among most major flood control agencies that in the design of the major storm drainage system for urban areas the 1-percent storm (100-year return period) should be used, except in the design of water impoundment structures that exceed a specified capacity. Dam design should comply with the requirements provided in the State of Utah Statutes and Administrative Rules for Dam Safety (UAC, 2010 After consultation with City officials the 10-year return period was chosen for determining the adequacy of the initial drainage system and this master plan effort focuses on the initial drainage system. ---PAGE BREAK--- ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update II-2 Design Rainstorm In 1999 Salt Lake County contracted with TRC North American Weather Consultants and Meteorological Solutions Inc. to complete an updated rainfall intensity duration analysis of Salt Lake Valley. The 1999 rainfall study performed an “analysis of valley-wide, warm season (March – October) precipitation, for use in runoff-related design consideration.” The results of the study were summarized on “eighteen maps covering area rainfall at duration ranging from 15 minutes through 24 hours for return periods from 2 years to 100 years (Select maps located in Appendix A summary of design rainfall depths for various return periods for Murray City are shown on Table II-1. TABLE II-1 10-YEAR RETURN PERIOD DESIGN RAINFALL DEPTHS RAINFALL DEPTH (INCHES) BY DURATION 30-MIN 1-HOUR 3-HOUR 6-HOUR 0.72 0.90 1.15 1.45 The storm duration that will produce the highest peak runoff flow rate is dependent on rainfall- duration relationships, the characteristics of the basin, and upon the level of detention storage. Generally speaking, the longer runoff takes to flow through a drainage basin or detention basin, the longer the critical storm duration. A duration sensitivity analysis of the hydrologic study area was performed by successive model runs using 30-minute, 1-hour, 3-hour, and 6-hour storm durations. The storm duration producing the largest peak runoff for developed areas tributary to detention basins was typically the 1-hour storm. To compute runoff from a given storm, the distribution of the rainfall through time must be known. Critical runoff events from urban areas along the Wasatch Front are caused by cloudburst type storms, characterized by short periods of high intensity rainfall. During the 1960s and early 1970s, Dr. Eugene E. Farmer and Dr. Joel E. Fletcher completed a major study of the precipitation characteristics for storms in northern Utah. In Davis County, Farmer and Fletcher (1971) examined rainfall gage records and classified storms based on whether the heaviest rainfall of the storm fell in the first, second, third, or fourth quarter of the storm period. Farmer and Fletcher found that “first and second quartile storms together comprise 76 percent of those storms containing a burst of 5-minute duration, with a 2-year recurrence interval and 92 percent of storms containing a burst of 10-minute duration, with a 10-year recurrence interval.” Farmer and Fletcher developed model storms for first and second quartile storms. The second quartile storm distribution produces the higher runoff peaks and is the rainfall distribution used in this study for runoff hydrograph calculations. DRAINAGE BASIN CHARACTERISTICS A drainage basin is an area where all rainfall or snowmelt runoff within it will collect to a common point. Drainage basins may also be referred to as watersheds or catchments. Subbasins are smaller drainage basins located within a larger drainage basin. Drainage subbasin boundaries depend upon both the topography and the location of storm drainage facilities. The drainage subbasin boundaries delineated for the existing conditions models are shown on Figure II-2. ---PAGE BREAK--- SB323 SB578 SB488 SB537 SB502 SBT1103a SB559 SBT1202 SB444 SB661 SB566 SB530 SB573 SB375 SB506 SB531 SB458 SB554 SB431 SB516 SB542 SB110 SB349 SB432 SB558 SB529 SB661b SB556 SB486 SB535 SB595 SB455 SB646 SB284 SB461 SB662 SB504 SB218 SB440 SB261 SB360 SB428 SB505 SB459 SB553 SB502 SB1701 SB577 SB1205 SB460 SB497 SB602 SB121 SB422 SB598 SB587 SB591 SBT1102g SB217 SB1507 SB325 SB667 SB109 SB399 SB118 SB433 SB550 SB555 SB524 SB2104 SB589 SB557 SB673 SB434 SB115 SB582 SB204 SB1101 SB624 SB1509 SB603 SB590 SB8 SB466 SB526 SB1603 SB563 SB1401 SB98 SB116 SB262 SB416 SB5 SB1201 SB138 SB205 SB1102 SB77 SB99 SB3105 SB473 SB534 SB73 SB1307 SB93 SB141 SB430 SB87 SB462 SB400 SB1103 SB502 SB49 SB382 SB31 SB467 SB490 SB32 SB664 SB560 SBT1102d SB47 SB3104 SB539 SB436 SB117 SB538 SB19 SB1301 SB201 SB515 SB361 SB672 SB634 SB38 SB26 SB78 SB630 SB541 SB51 SB4 SB496 SB183 SB199 SB396 SB585 SB44 SB100 SB1502 SB429 SB3101 SB219 SB393 SB1302 SB347 SB15 SB144 SB621 SB153 SB203 SB41 SB599 SB152 SB173 SB9 SB276 SB517 SB124 SB607 SB3206 SB420 SB27 SB171 SB575 SB277 SB344 SB111 SB445 SB37 SB48 SB154 SB146 SB464 SB2103 SB50 SB367 SB1508 SBT1102c SB631 SB487 SB1402 SB478 SB225 SB547 SB39 SB2101 SB449 SB353 SB114 SB156 SB2 SB147 SB469 SB3205 SB231 SB212 SB612 SB106 SB66 SB67 SB624b SB568 SB79 SB60 SB457 SB282 SB1503 SB1 SB480 SB1505 SB412 SB1203 SB671 SB126 SBT1101b SB338 SB527 SB549 SB113 SB424 SB363 SB358 SB408 SB533 SB519 SB421 SB415 SB379 SB40 SB46 SB472 SB381 SB3 SB2105 SB444 SB368 SB354 SB24 SB6 SB85 SB357 SB228 SB372 SB536 SB493 SB369 SB572 SB119 SB513 SB392 SB58 SB528 SB345 SB190 SB316 SB510 SB1308 SB395 SB574 SB359 SB468 SB140 SBT1101 SB422b SB129 SB639 SB1403 SB562 SB92 SB235 SB438 SB13 SB583 SB514 SB446 SB137 SB163 SB159 SBT1103b SB232 SB407 SB522 SB500 SB390 SB1204 SB214 SB543 SB20 SB101 SB518 SB475 SB150 SB16 SB509 SB76 SB540 SB161 SB95 SB134 SB45 SB120 SB418 SB151 SB604 SB339 SB14 SB195 SB1202 SB425 SB1303 SB669 SB389 SB340 SB227 SB3201 SB7 SB131 SB28 SB1513 SB174 SB122 SB12 SB596 SB453 SB69 SB451 SB409 SB64 SB355 SB576 SB112 SB191 SB380 SB413 SB1506 SB200 SB169 SB23 SB402 SB1609 SB3202 SB43 SB105 SB632 SB452 SB1605 SB176 SB584 SB90 SB42 SB579 SB125 SB471 SB622 SB665 SB175 SB335 SB523 SB531b SB180 SB1304 SB97 SB315 SB86 SB427 SB640 SB281 SB181 SB33 SB605 SB398 SB71 SB81 SB136 SB642 SB328 SB1702 SB170 SB103 SB215 SB259 SB158 SB376 SB641 SB1608 SB22 SB627 SBT1514 SB18 SB454 SB193 SB593 SB370 SB414 SB1504 SB507 SB417 SB198 SB133 SB65 SB383 SB213 SB1306 SB391 SB280 SB89 SB511 SB644 SB221 SB1104 SB149 SB285 SB21 SB163b SB135 SB207 SB570 SB162 SB397 SB188 SB17 SB208 SB155 SBT1102e SB216 SB2102 SB202 SB104 SB3102 SB364 SB352 SB194 SB348 SB84 SB234 SB442 SB172 SB670 SB165 SB68 SB1604 SB142 SB108 SB1607 SB56 SB164 SB83 SB387 SB356 SB498 SB643 SB53 SB1501 SB25 SB107 SB501 SB600 SB196 SB11 SB626 SB192 SB1606 SB637 SB394 SB586 SB145 SB592 SB1310 SB1514 SB220 SB63 SB1312 SB544 SBT1102a SB608 SB654 SB148 SB96b SB613 SB102 SB483 SB342 SB186 SB187 SB625 SB57 SB30 SB620 SB206 SB1105 SB130 SB588 SB1404 SB278 SB184 SB185 SBT1513 SB55 SB660SB658 SB1311 SB479 SB394b SB94 SB1512 SB10 SB508 SB1305 SB647 SB594 SB580 SB3103 SB177 SB167 SB59 SB70 SB1703 SB3203 SB441 SB229 SB61 SB494 SB655 SB615 SB581 SB439 SBT1102b SB132 SB482 SB52 SB128 SB1610 SB1309 SB419 SB666 SB623 SB373 SB3204 SB470 SB499 SB548 SB597 SB525 SB341 SB157 SB260 SB656 SB443 SB82 SB160 SB143 SB1511 SB384 SBT1102f SB182 SB484 SB96 SB546 SB531a SB233 SB96b SB485 SB512 SB29 SB521 SB614 SB619 SB635 SB532 SB75 SB628 SB520 SB2106 SB668 SB1601 SB209 SB1602 SB618 SB324 SB346 SB420b SB463 SB343 SB127 SB652 SB648 SB163c SB609 SB1515 SB650 SB616 SB545 SB1510 SB645 4500 S 1300 E 900 E STATE ST I-15 SB FWY 5900 S VINE ST I-215E EB FWY 4800 S I-215E WB FWY REDWOOD RD I-215E SB FWY I-215E NB FWY 5400 S 7200 S 7000 S 5300 S 6400 S 700 E I-215W EB FWY 6200 S TAYLORSVILLE EXPY WASATCH BLVD HIGHLAND DR HIGHLAND DR MURRAY CITY STORM DRAINAGE MASTER PLAN UPDATE DRAINAGE SUBBASIN BOUNDARIES FIGURE II-2 0 5,000 10,000 2,500 Feet ¦ LEGEND Subbasins Annexation Area ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update II-3 Subbasin characteristics were developed based on field observations, the 2009 Murray City aerial photographs, 4-foot elevation contour data available for the former boundaries of the City, 0.5 meter elevation contour data available for the annexed area, and soils coverage from the state GIS site which comes from the Natural Resource Conservation Service database (NRCS, 2010). Subbasin characteristics included: • Subbasin area • Hydrologic Soil Type • Percentage of impervious area • SCS curve number • Conveyance characteristics Hydrologic characteristics of each subbasin are given in the model input files provided on the CD in Appendix D. Subbasin identification numbers are labeled on Figure II-2. Subbasin Area Subbasins were updated within the GIS database using topographic mapping and the locations of storm drainage facilities. Digital base mapping of the City consists of contours with physical features such as property lines and streets. Site visits were made to verify drainage patterns in areas where the drainage directions could not be determined using the available mapping. Subbasins vary in size depending upon the level of development within the subbasin and the locations for which hydrographs were needed. Hydrologic Soil Type Hydrologic soil type is a general indication of the soil’s infiltration capacity. Soils are assigned a hydrologic type of A, B, C, or D by the Natural Resource Conservation Service (NRCS). Soils of hydrologic soil type A have the highest infiltration rate, and therefore produce the least amount of runoff. Soils of hydrologic soil type D have the lowest infiltration rate, and therefore produce the highest amount of runoff. Soils in the study area are mostly type A, C, and D. Each subbasin was assigned a hydrologic soil type based upon the NRCS mapping. Impervious Area Impervious areas within each subbasin were updated using the 2009 aerial photography, average impervious areas per residence, and impervious area mapping from Murray City. The impervious area was divided into two components, directly connected impervious areas and unconnected impervious areas. Directly connected impervious areas have a direct path for runoff to a conveyance such as a pipe, gutter, or channel. Directly connected impervious areas include roadways, parking lots, driveways, and sometimes the roofs of buildings. Runoff from unconnected impervious areas crosses pervious areas before reaching a conveyance. Examples of unconnected impervious areas include sidewalks that are not adjacent to the curb, patios, sheds, and usually some portion of the roofs of buildings. It is important to distinguish between directly connected and unconnected impervious areas because runoff from directly connected impervious areas reaches the drainage conveyance system quickly and usually determines the magnitude of the peak flow rate upstream from detention. Impervious areas such as back yard patios, which drain to grassed or landscaped areas impact storm runoff peak flows much less than directly connected impervious areas. ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update II-4 Based upon field observations, the directly contributing impervious area for a typical residential lot in Murray City generally includes the majority of the driveway and 26 percent of the home and garage area. The runoff from the remaining 74 percent of the home and garage area typically flows over pervious areas before reaching the street. Please note that roughness coefficients (Manning’s n values) for sheet flow were estimated using the information on page 3-3 of Technical Release-55 (TR-55), which can be found in Appendix A. SCS Curve Number Each basin was assigned an SCS (Soil Conservation Service) curve number. The curve number describes the relationship between precipitation and runoff for the pervious and unconnected impervious portions of the subbasin. Curve numbers range from 0 to 100. Areas with high runoff rates have high curve numbers. Areas that are more pervious have lower curve numbers. For example, parking lots and other impervious surfaces have curve numbers of about 98, whereas pervious areas such as fields, lawns, and gardens, typically have curve numbers between 70 and 89. Curve numbers for each subbasin were estimated using a methodology presented by the Soil Conservation Service (SCS, 1972). Residential areas usually have C soil types due to imported topsoil. C soil types have a curve number of 74. Because much of the study area includes residential areas, a conservative minimum SCS curve number of 74 was applied to the entire area whenever calculated curve numbers were below that value. Conveyance Characteristics Storm drainage conveyance characteristics were estimated based on available system information using storm drainage facilities mapping and available drawings, field observations of the type and size of the conveyance, and approximate slope as determined from the contour data in conjunction with given storm drain depths. Future Land Use and Hydrologic Characteristics Most of Murray City has been developed, and parcel owners are required to limit storm runoff from their parcels to 0.2 cfs/acre, wherever new development or redevelopment has occurred. The required detention of 0.2 cfs/acre applied to future developed areas does not worsen existing problems or create new problems in the existing models. STORM DRAINAGE UPDATE MODELS DEVELOPMENT Methodology The Murray City Storm Drainage Update Models are a combination of an ArcGIS model and the United States Army Corps of Engineers (USACE) Hydrologic Modeling System (HEC-HMS). As As indicated previously, the storm water models prepared for the 2000 Master Plan were translated into HEC-HMS. HEC-HMS calculates peak flows and runoff hydrographs for all model elements including subbasins, reaches, junctions, and detention basins. Delineation of subbasins and determination of subbasin and reach characteristics were performed using the ArcGIS model. Subbasin boundaries and storm drain conveyance shapefiles were then imported as background images into HEC-HMS for creation of the storm drainage model. ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update II-5 Subbasins were modeled using the SCS curve number loss method and the kinematic wave transform method. Modeling Existing Conditions The existing system models were updated to identify existing deficiencies in the storm drainage system. Conveyances included in the models were those which receive drainage from at least one subbasin. Modeling of the existing drainage system is presented in the following chapter (Chapter III). Modeling Future Conditions Future conditions were not modeled after analyzing the potential for new development. The City currently has a specific release rate requirement of 0.2 cfs/acre from parcels with new development. Undeveloped areas were analyzed assuming detention restricting the storm runoff to 0.2 cfs/acre. As discussed previously, future development will not adversely affect the current storm drain system or the proposed improvements. Computation of Runoff Hydrographs Hydrographs were computed for each subbasin, conveyance, junction, detention basin inlet, and detention basin outlet. The maximum value from each hydrograph is the peak runoff flow rate. Hydrographs were calculated for the 30-minute, 1-hour, 3-hour, and 6-hour storm duration. The highest peak flow rate identifies the critical storm duration and is the flow rate used for design or evaluation of that element in the model. As the drainage plan for the City’s system was developed, runoff hydrographs were calculated for the conveyances. The peak flow rates were then compared to the capacities of the analyzed conveyances to determine where problems might exist. Peak runoff flow rates for each conveyance are provided in Appendix C. An electronic copy of the storm drainage models models along with the HEC-HMS installation software, GIS data, and backup information are included on CD-ROM in Appendix D. ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update III-1 CHAPTER III EXISTING STORM DRAINAGE SYSTEM Little Cottonwood Creek, Big Cottonwood Creek, the Jordan River, and the Jordan and Salt Lake City Canal provide outlets for storm drainage facilities in Murray City. Little Cottonwood Creek and Big Cottonwood Creek are tributary to the Jordan River. Major basins, modeled conveyances, detention basins, and drainages of the existing storm drainage system are shown on Figure III-1. Major basins are named based on relative location in the City (North, East, Northeast, Northwest, West, Central West, Central, Central East, Central South, South, and Southeast). NATURAL DRAINAGES Little Cottonwood Creek Little Cottonwood Creek flows through approximately 4.5 miles of Murray City from Union Park Avenue and I-215 to the Jordan River at 4800 S. The creek provides drainage for the Southeast, Central East, Central, and North Basins. It is conveyed through the City by a series of open channels and road crossing structures before discharging to the Jordan River after crossing Murray Boulevard. Big Cottonwood Creek Big Cottonwood Creek flows through approximately 4.2 miles of Murray City from 1300 E and 4705 S to the Jordan River at 4200 S. The creek provides drainage for the Northeast, East, and North Basins. It is conveyed through the City by a series of open channels and road crossing structures before discharging to the Jordan River after crossing 500 E. Jordan River The Jordan River flows through approximately 4.6 miles of Murray City along the western border of the City. The Jordan River provides drainage for the West, Central South, Central West, and North Basins. Jordan and Salt Lake City Canal The Jordan and Salt Lake City Canal flows through approximately 1.9 miles of Murray City from 900 E and I-215 northeast to Van Winkle. The canal provides drainage for the Southeast and Northeast Basins. The canal is conveyed through a series of open channels and culverts before exiting the City boundary. It must be noted that although the canal currently is part of the storm drainage system, especially for older irrigation pipes which also convey storm drain runoff, the canal cannot be used as an outlet for future storm drain projects. DETENTION Existing detention basin locations are shown on Figure III-1. Stage capacity and discharge data was estimated by field measurements, contour data, available design drawings and the City’s 0.2 cfs/acre maximum discharge requirement. ---PAGE BREAK--- $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ North East South West Northeast Central South Central Southeast Central West Northwest Central East JORDAN RIVER EAST CANAL JORDAN AND SLC CANAL BIG COTTONWOOD CREEK NORTH JORDAN CANAL BRIGHTON CANAL 4500 S 1300 E 900 E STATE ST I-15 SB FWY I-15 NB FWY 5900 S VINE ST I-215E EB FWY 4800 S I-215E WB FWY I-215E SB FWY I-215E NB FWY 5400 S 7200 S 7000 S 5300 S 6400 S 700 E I-215W EB FWY I-215W WB FWY 6200 S VANWINKLE EXPY TAYLORSVILLE EXPY WASATCH BLVD VINE ST MURRAY CITY STORM DRAINAGE MASTER PLAN UPDATE EXISTING STORM DRAINAGE MODELED CONVEYANCES FIGURE III-1 0 5,000 10,000 2,500 Feet ¦ LEGEND 10-inch Dia.

Ditch Curb and Gutter as Conveyance $ Rivers and Canals ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update III-2 STORM DRAIN CONVEYANCES Capacities of storm drainage pipes were estimated based upon size, slope, material type, Manning’s equation, and approximated inlet capacity limitations. Where known pipe slope was not available, slope was estimated based on the contour data and pipe depth, or upon a minimum slope of 0.4%. Estimated pipe capacities are based on conceptual level engineering and do not consider detailed inlet capacity and restrictions. Estimated capacities also do not consider allowable surcharging that might provide additional capacity. While the estimated capacities may not be precise, they are consistent with the precision of the runoff estimates and are sufficient for drainage master planning efforts. Capacities of modeled existing storm drains collecting runoff at the exit point of subbasins and main storm drainage conveyances can be found in Appendix A. The capacity of the curb and gutter was estimated for a standard residential street with the water surface level with the top of the curb. Maximum flow capacities were calculated with Manning’s equation for gutter slopes from 0.4 to 9 percent. Because gutters are often obstructed by parked cars or other obstacles, the maximum flow capacity was reduced to an allowable capacity according to a methodology outlined in the Urban Storm Drainage Criteria Manual (Denver Regional Council of Governments, 2001). This methodology applies a reduction factor to the maximum capacity to estimate the allowable capacity of the gutter. The reduction factor is a function of the gutter slope. Curb and gutter capacity varies from 7 to 17 cfs for the typical range of slopes allowed on residential streets assuming the typical 6" curbs found throughout the City. ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update IV-1 CHAPTER IV DRAINAGE SYSTEM EVALUATION ADEQUACY OF STORM DRAINAGE FACILITIES The storm drainage criteria established as part of this study includes that the initial storm drainage system should be designed for the 10-year storm runoff event. The system was not analyzed for the 100-year storm runoff event. The combination of the storm drain pipes and the curb and gutter should convey the runoff from the 10-year storm runoff event without overtopping the curb. EXISTING AND BUILDOUT STORM DRAINAGE PROBLEM AREAS Storm drainage problem areas were identified by comparing the existing peak flows from the drainage system models with the estimated capacity of the existing storm drainage facilities and by collaborating with Murray City to identify known problem areas where frequent flooding occurs. Storm drainage problems are described in Table IV-1 and shown on Figure IV-1. Table IV-1 also includes a description of the location, the conveyance identification number, the peak flow rates for a 10-year storm for existing conditions, and the existing 10-year capacity of each problem conveyance. ---PAGE BREAK--- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 17 16 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 North East South West Northeast Central South Central Southeast Central West Northwest Central East 4500 S 1300 E 900 E STATE ST I-15 SB FWYI-15 NB FWY 5900 S VINE ST I-215E EB FWY 4800 S I-215E WB FWY REDWOOD RD 5400 S I-215E SB FWY I-215E NB FWY 7200 S 7000 S 5300 S 6400 S I-215W EB FWY 700 E I-215W WB FWY 6200 S VANWINKLE EXPY TAYLORSVILLE EXPY 4700 S VINE ST MURRAY CITY STORM DRAINAGE MASTER PLAN UPDATE STORM DRAINAGE PROBLEMS FIGURE IV-1 0 5,000 10,000 2,500 Feet¦ LEGEND Problem Areas City Boundaries ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update IV-2 TABLE IV-1 STORM DRAINAGE PROBLEMS PROBLEM ID # LOCATION CONVEYANCE ID* 10-YEAR STORM WATER FLOW (cfs) 10-YEAR CAPACITY (cfs) PROBLEM DESCRIPTION 1 Jeremy Ct and Jeremy Dr CN1513 23.1 4.3 Peak flow from the 10-year storm is greater than the capacity of the existing pipes. 2 Shenandoah to Fontaine Bleu CN1307 CN1505b CN1505c CN1512 31.7 32.1 20.2 20.4 18.6 7.7 14.9 10.9 Peak flow from the 10-year storm is greater than the capacity of the existing pipes.

Selection of the preferred alternative for each problem was a process of evaluation and refinement, rather than a simple choice between alternatives. The process of selecting a preferred alternative included: reviewing the list of storm drainage inadequacies, brainstorming possible solutions to the problems, screening alternatives based on feasibility and public acceptance, development of alternatives, comparison based on cost and function, and selection of the preferred alternative. The flows and pipe diameters provided in the capital improvement project descriptions are approximate and are for planning purposes only. A detailed hydrologic and hydraulic analysis should be performed during the design process for the master plan update improvement projects to identify final design pipe sizes. MURRAY CITY STORM WATER MANAGEMENT PLAN As part of the 2011 UPDES permit issued to Murray City from the State of Utah Department of Environmental Quality (DEQ) the City must develop a plan to retrofit sites that are adversely impacted by storm water quality. As part of the 2011 Storm Water Management Plan, projects included in the Storm Water Master Plan will be evaluated for post construction Best Management Practices (BMPs) during the design phase of each project. Evaluation criteria for projects will include: • Proximity to water body • Status of a water body (wetlands, pond, etc.) used to improve an impaired water body • Hydrologic condition of the receiving water body • Proximity to sensitive ecosystem or protected area • Any upcoming sites that can be further enhanced by retrofitting storm water controls Design questions to be addressed during post construction BMP evaluation will be: • Is this a highly impacted area? • Why is this area highly impacted? • How does the existing system work in this area? • What BMPs might address the problems? • Is there room to retrofit at the end of the line? • Would projects upstream maximize water quality and minimize impacts? • What are the anticipated costs? After evaluation, the City will decide what post construction BMPs meet the needs and requirements of both the project and storm water protection. ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update V-2 PRECISION OF COST ESTIMATES When considering cost estimates, there are several levels or degrees of precision, depending on the purpose of the estimate and the percentage of detailed design that has been completed. The following levels of precision are typical: Type of Estimate Precision Master Planning ±50% Preliminary Design ±30% Final Design or Bid ±10% For example, at the master planning level (or conceptual or feasibility design level), if a project is estimated to cost $1,000,000, then the precision or reliability of the cost estimate would typically be expected to range between approximately $500,000 and $1,500,000. While this may seem very imprecise, the purpose of master planning is to develop general sizing, location, cost, and scheduling information on a number of individual projects that may be designed and constructed over a period of many years. Master planning also typically includes the selection of common design criteria to help ensure uniformity and compatibility among future individual projects. Details such as the exact capacity of individual projects, the level of redundancy, the location of facilities, the alignment and depth of pipelines, the extent of utility conflicts, the cost of land and easements, the construction methodology, the types of equipment and material to be used, the time of construction, interest and inflation rates, permitting requirements, etc., are typically developed during the more detailed levels of design. At the preliminary or 10% design level, some of the aforementioned information will have been developed. Major design decisions such as the size of facilities, selection of facility sites, pipeline alignments and depths, and the selection of the types of equipment and material to be used during construction will typically have been made. At this level of design the precision of the cost estimate for a $1,000,000 project would typically be expected to range between approximately $700,000 and $1,300,000. After the project has been completely designed, and is ready to bid, all design plans and technical specifications will have been completed and nearly all of the significant details about the project should be known. At this level of design, the precision of the cost estimate for the same $1,000,000 project would typically be expected to range between approximately $900,000 and $1,100,000. ESTIMATED CONSTRUCTION COSTS Estimated construction costs for the storm drainage pipe lines include manholes, inlets, roadway repair, curb and gutter replacement, and utility relocation for larger storm drain diameters. It was assumed that curb and gutter would not be replaced for storm drain diameters smaller than 30-inches. It was also assumed that one existing utility would need to be relocated for storm drain diameters larger than 30-inches, and two existing utilities would need to be relocated for storm drain diameters larger than 48-inches. Estimated construction costs for detention facilities include excavation, grading, inlet and outlet structures, and general landscaping. Unit costs for the construction cost estimates are based on conceptual level engineering. Unit construction costs were estimated based on construction cost indices, communication with material suppliers, and HAL experience with similar construction. All costs are presented in ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update V-3 2010 dollars. Recent price and economic trends indicate that future costs are difficult to predict predict with certainty. Engineering cost estimates given in this study should be regarded as conceptual level as appropriate for use as a planning guide. Only during final design can a definitive and more accurate estimate be provided. A detailed cost estimate of each project along with unit pipe costs and detention basin project costs are provided in Appendix B. CAPITAL IMPROVEMENTS PLAN Recommended projects are presented in Table V-1 with master plan level storm drain pipe diameters. Identified problems (Table IV-1) were reviewed in workshops with City staff. Problems 1, 4, 6, 8, 11, 13, 15, 16, 18, 34, 35, 36, 37, 40, 46, 50, 52, 53, and 54 were designated to be put on a watch list for further assessment. Project ID #s do not correspond to Problem ID but problems alleviated by the projects are listed in Table V-1. Estimated construction costs are also included this table. Figure V-1 shows the location of each project by ID number. The cost estimates are master planning level and reflect current pricing. They include mobilization, engineering and contingency. They do not include costs associated with acquisition of right-of-way, legal fees, or administration. Actual costs may vary. Priority is assigned to each recommended project. Priority levels are either A, B, or C, and refer to projects scheduled to be completed in 0 to 5 years, 5 to 10 years, or beyond 10 years, respectively.

TABLE V-2 CAPITAL IMPROVEMENTS SUMMARY PRIORITIZATION TIME FRAME ESTIMATED TOTAL COST (2010 U.S. DOLLARS) ESTIMATED TOTAL COST W/ ALTERNATIVES (2010 U.S. DOLLARS) A 0 to 5 years $7,204,000 $7,286,000 B 5 to 10 years $11,494,000 $11,256,000 C Beyond 10 years $4,511,000 No Alternatives SUMMARY OF RECOMMENDATIONS 1. The City should proceed with implementation of the Storm Drainage Capital Improvements (see Table V-1). 2. We recommend that the City require all new developments to comply with the Murray City Drainage Design Criteria. 3. We recommend that the City continue the design review and inspection policies that will ensure City design and construction standards are achieved. 4. We recommend that the City continue to require new developments to detain peak storm runoff flows. 5. We recommend that Murray City be actively involved in regional storm drainage planning efforts, notably along the Van Winkle Expressway. 6. The Murray City Geographical Information System (GIS) and the storm drainage models data should be updated as further land use, conveyance, capacity, and detention data become available. 7. We recommend that detention basins required for future development peak discharge mitigation be located on land owned by or dedicated to the City. 8. The storm drainage master plan should be periodically reviewed and updated dependent upon change and new development but not less than 5 years. ---PAGE BREAK--- Murray City Storm Drainage Master Plan Update R-1 REFERENCES Denver Regional Council of Governments. 2001.

*Attributes of subbasins located in the South Basin can be seen on the CD located in Appendix D Subbasin Attributes 8/8 ---PAGE BREAK--- CONVEYANCE CAPACITIES Storm drainage facilities and features conveying storm drainage from subbasins have been represented in the model. Smaller storm drainage facilities within subbasins are represented in the characteristics of the subbasin in which they are located. As explained in the report, capacities of storm drainage pipes were estimated based upon size, slope, material type, Manning’s equation, and approximated inlet capacity limitations. These estimated conveyance capacities were then compared against the corresponding HEC-HMS model peak discharge. The following table includes capacities and model output comparison. Each of the columns in the table is labeled and described below: Col. Description 1 Assigned conveyance ID. Each conveyance ID name is prefixed by “CN_” or “CV_” followed by the identification number of the conveyance. 2 Major Basin in which the conveyance is found. 3 Length of the conveyance based upon the 2000 SDMP report or upon city data of in- place pipes. 4 Slope of the conveyance based upon the 2000 SDMP or upon 4 ft and 0.5 m contours for Murray City and depths corresponding to in-place pipes. 5 Mannings n value based upon the material of the conveyance. 6 Shape of the conveyance. 7 Diameter of circular conveyances. 8 Width of trapezoidal conveyances. 9 Side slope of trapezoidal conveyances, horizontal:vertical. 10 Capacity of conveyance based on Manning’s Equation assuming full flow in the pipe. Mannings Equation: ( ) ( ) Q cfs n A A Pw S ( ) . =     1 486 2 3 1 2 11 Inlet control capacity. Based on a maximum velocity of 8 ft/s for pipes equal to or less than 30 inches in diameter and 10 ft/s for pipes with diameters larger than 30 inches. 12 Capacity of curb and gutter flow. Based upon Manning’s Equation (see 10) for 6-inch back curb and gutters and is doubled for curb and gutter on both sides of the street. 13 Total capacity for the conveyance. Based upon the controlling or smaller capacity between capacity due to Manning’s Equation and inlet control capacity, in addition to the curb and gutter capacity of the street. 14 Peak flow in the conveyance. The peak flow is from the largest peak flow between the four 10-year storm flows. The peak flows can be seen in the 2010 Existing Peak Flows for All Elements. 15 Amount of flow over capacity. Based upon the amount of peak flow greater than the capacity of the conveyance.
