Development Review Manager Public Works Department Town of Oro Valley Oro Valley, Arizona 85737 RE: Drainage Report Addendum for Parcel 224-27-299A, Monte Del Oro, Easterly Portion Lot 187, Dear Mr. Keesler: This letter is an addendum to JEF's drainage report dated May 4, 2007. Although the May 41h report was approved, the drainage design scheme outlined in the report required that the property owner secure a permanent drainage easement from the owner of Lot 186 for the purpose of constructing an offsite diversion berm. Since the owner of Lot 186 was not willing to grant an easement, the drainage scheme was revised accordingly. A drainage swale will now be constructed immediately upstream of the proposed house pad as shown on the attached preliminary grading/site plan prepared by Ron Staub Associates, LLC. Offsite runoff entering the parcel along the eastern portion of the northern boundary will now be captured and conveyed around the east and west side of the proposed house pad. The approximate quantity of flow conveyed in each subsection of the swale was determined from the existing -conditions HEC-RAS model using the flow distribution at Section 6 as a guide (see attached drainage exhibit). The maximum quantity of flow conveyed in the eastern portion of the swale around the east side of the house pad was determined to be approximately 16 cfs. The maximum quantity of flow conveyed in the western portion of the swale was determined to be approximately 197 cfs. A typical section of the swale is shown on the revised site plan. The proposed slope is approximately 1.25%. The hydraulic properties associated with the maximum discharge (197 cfs) are summarized on the attached normal -depth computation sheet. Assuming a minimum freeboard of one foot, the minimum depth of the swale will be 2.8 feet. Since the maximum anticipated flow velocity in the swale will be approximately 5.39 feet per second (fps), the house pad will be protected with rock riprap. Per Pima County's Technical Policy document TECH-006 for dumped rock riprap (copy attached), the minimum D50 size of the rock will be nine (9) inches, and the minimum layer thickness will be 18 inches. The minimum toe - down depth will be four (4) feet. The encroachment analysis presented in the May 4, 2007 report was also revised to reflect removal of the berm. The results of both the existing conditions and developed conditions HEC-RAS analysis are summarized in the following tables. However, only the revised input/output listing for developed conditions is attached to this letter, since the existing conditions listing provided in the May 40' report is still valid. 8400 S.

The maximum change in the flow velocity is 0.41 feet per second (fps). The maximum flow velocity adjacent to the proposed pad protection, from the HEC-RAS analysis, is 3.64 fps. However, since the normal -depth flow velocity associated with the swale is 5.39 fps, the rock riprap was designed using this velocity to ensure adequate protection. In addition, the minimum finish -floor elevation was increased one foot from 2515.5 to 2516.5 to ensure that the minimum pad elevation would be at least equal to the minimum top of bank elevation in the adjacent swale (2516), which is one foot above the depth of flow in the Swale.

JE Fuller/Hydrology & Geomorphology, Inc. PINIA COUNTY REGIONAL FLOOD CONTROL DISTRICT TECHNICAL POLICY POLICY NO.: Technical Policy, TECH-006 EFFECTIVE DATE: March 2"), 2006 POLICY NAME: Erosion Protection of Fill Pads in Floodway Fringe Areas PURPOSE: To clarify 16.26.040.13 regarding the protection of the till pads firom erosion in order to establish consistent permitting requirements that are sufficiently protective of the fill pad and structure for the flood hazards that have been identified. BACKGROUND. The Floodplain and Erosion Hazard Management Ordinance (2005-FC2) provision 16.26.040.13 requires that any (ill placed in a floodway fringe be adequately protected from erosion by rip -rap vegetative cover, bulk -heading, or other approved method, but does not establish appropriate levels of erosion protection based on the hazards that may be encountered due to the lateral forces of moving water. In addition, Ordinance provision 16.25.050.E requires that fill pads extend to a distance 25 feet from the edge of the structure, but does not specify methods of erosion protection. Historically, the need for erosion protection has not been addressed at the time of permitting and therefore, erosion protection has not been provided. The following publications discuss till pads and/or erosion protection: I ) The FENIA publication, Manuffactured Hone Installation in blood Ifa�ard rfrcus, FF.,tI1f�5, published in September 1985, prescribes: a. A minimum of 25 feet of fill beyond the perimeter of the structure, which is consistent with the ordinance. b. Vegetative cover as erosion protection when velocities are 5 fps or less, rock rip -rap for velocities between 5-10 fps, and prohibit fill pads in areas of ,renter velocity. 2) The ZOOS draft of FG11,185 prescribes: a. A reduced fill pad dimension of 5 feet or twice the fill pad height (from 25) from the perimeter of the stricture. b. Limitations on the use fill pads where it will constrict floodplains and cause significant increases in flood heights or velocities 3) 'File City of Tucson Drainage Standards Manual, specifically Chapters 6 and 9, provides methods to deterniine erosion.'scour depths, and rip -rap sizin3. a. The scour equation in Chapter 6 includes the effects of local scour due to obstructions of flow, such a till pad. The applicable portions of the scour equation will be used in estimating potential scour. I). The rip -rap sizing chart is intended for use In channel design, and indicates the need for rile -rap at velocities less than 5 fps. This use of this chart is intended to augment the FENIAS5 document when applied to fill pads. 4) The Pima County Drainage and Channel Design Standards Manual, and the Grading Design Manual provide additional criteria for the design of erosion protection of channels based oil flow velocity, and cut and fill slopes. The criteria include riprap sizing, side slope steepness, toe clown depth; and maximum height requirements. The COT Drainage Manual and the Pima County Drainage and Channel Design Standards Itilanual indicate that erosion protection in addition to vegetative cover is needed at approximate flow velocities of 2.5 fps and greater. Because they are more restrictive than FENIA85 and more representative of the Arizona soil and hydraulic conditions, these documents will be used for this policy However, the COT Drainage Manual Equation 6-3 is an additive equation that establishes a total potential scour based on a variety of scour components. Since some of these components are not applicable for fill pads in broad floodplains, this policy may establish design criteria that is not as restrictive as the equation. In addition, in order to efficiently and effectively address the need for minimum erosion protection standards across a wide variety of flow regimes, RFCD has chosen to apply minimum standards categories using ranges of flow depths and flow velocities. The criteria from these publications and calculations are used as the basis for this policy. POLICY: If the fill pad encroaches into all Erosion hazard Setback, is in a study area that establishes a requirement for an engineering analysis, or if RFCD determines that, due to unusual conditions, engineering is required, the engineering analysis requirements supersede this policy. The following policy shall apply in floodplain areas outside of Erosion Hazard Setbacks or other areas rc(Iui►-ing engineering: 1) in all cases, the fill pad sliall be constructed at or above the BFE for at least 25 feet outside the perimeter of the stricture, and the side slopes shall be no steeper than 3:1 (from both Channel and Grading Standards). If engineering analysis is provided that justifies a reduction, the engineering analysis shall draw conclusions regarding the level of protection needed and this policy is not applicable. 2) ']'lie attached table, which establishes 4 nunimuni erosion protection standards, shall be used wlicn this policy applies. The description of each standard is as follows: a. No additional erosion protection other than vegetation is required (Green category): This category applies when flow velocities are less than 2.5 fcct per second, and generally applies in sheet flooding areas, Af i Zones, Shaded X Zones, AO I Zones where the slope is 1 % or less, or where maximum velocities at the fill pad are known and are less than 2.5 fps. The applicant shall specify the type and quantity of vegetation on the site plan. Fill pad protection must be placed along the entire length of all sides that experience flood flows and must completely surround any fill pad that is surrounded by floodwaters. b. additional protection consisting of G" rip -rap, with 3 ibot toe down (Yellow category): This category applies when flow velocities are 2.5 to less than 4.0 feet per second, and generally applies in AO1 Zones where the slope is more than 1 AO2 Zones where the slope is I°a or less, or where maximum velocities at the fill pad are known and are between 2.5 and 4 fps. The applicant shall specify that the fill be protected by the use of geo-textile titter fabric underlying angular rock rip -rap with a DS()= b", a minimum thickness of 12".and a minimum toe -down depth of 36". Fill pad protection must be placed along the entire length of all sides that experience flood flows and must completely surround any fill pad that is surrounded by floodwaters. The toe -down depth can be accomplished by either extending the rip -rap into the native soil at the same slope to the appropriate depth or by using a 12" thick vertical cut-off wall constructed where the rip -rap meets the natural grade. See fill pad detail (Attached). c. additional protection consisting of9" rip -rap, with 4 foot toe down (Orange category): This category applies when flow velocities are 4.0 to less than 5.5 feet per second, and ,,enerally applies in AO2 Zones where the slope is more than l ° o but less than 2(1//o, or where nlaxilnllill velocities at the till pall are knows) and are between 4.0 and 5.5 fps. The applicant shall specify that the fill be protected by the use or"co-textile filter fabric Underlying angular rock rip -rap with a D5O= 9", a mininuun thickness of 18"1 and a inininluill toe -down depth of 48". Fill pad protection must be placed along the entire length of all sides that experience flood flows and rllllst Colnpletely surround any fill pad that is surrounded by floodwaters. The toe -down depth can be accomplished by either extending the rip -rap into the native soil at the same slope to the appropriate depth or by using a 12" thick vertical cut-off wall constructed where the rip -rap meets the natural grade.See fill pad detail (Attached). d. Engineering analysis required (Purple category): This category applies when flow velocities are 5.5 feet per second or greater. Any fill pad proposed in these areas shall have in engineering analysis that establishes adequate protection from scour and shall include, at a minimum rip -rap size, thickness, and inimmunl toe down depth 3) When an engineering analysis is required for this and/or other reasons, including Erosion Hazard area reduction, encroachment analysis, based on Special Studies or for unusual conditions the engineering analysis also shall prescribe the uiininluill erosion protection and this policy is not applicable. / APPROVED BY: --..

But your call requesting redlines of Improvement Plans just seems to start the endless loop again. You quoted an e-mail from early May. That e-mail prompted a meeting with all of the OV staff that have been involved in the evolution of this lot split. So that e-mail is badly outdated in relation to the status of the project today. As a result of that meeting, Paul Keesler indicated that all communications on this project would go thru Manny. My very next submittal to Manny was forwarded to David Ronquillo since Manny had left. David's response e- mail (attached) was a list of remaining requirements, but they did not reflect the discussions at the meeting. I responded to that e-mail with a copy to Paul Keesler. Paul's response e-mail (also attached) seemed to bring things back to coincide with the meeting. My delivery yesterday was addressed to David Ronquillo and David Laws to bring in the final two required items. The e-mail you read to me simply does not apply at all any more. Please review this with Paul Keesler to confirm my comments. If there are still items outstanding, I am prepared to get them to you. Help. I feel that I am again caught in this endless whirlwind again. Ron Ronald J. Staub, PE RonStaubAssociates, LLC 2420 West Catalpa Road Tucson, AZ 85742-9447.

With this said, when you and I last spoke, you relayed to me that the actual building configuration is undetermined at this time. In fact your client may sell the lot to someone else to develop. The building pad can be generic (i.e. a square larger than what you expect a reasonable residence would encompass). The most important thing that will be gleaned of the plan is that there is adequate FFE with respect to the adjacent floodplain and the ability to get a reasonable connectivity (i.e. slope) in the driveway to Lambert Lane. I will coordinate this with David & David. Paul Keesler, P.E. Development Review Division Manager Town of Oro Valley 08/25/2008 Page 2 of 3 Department of Public Works 11,000 N. La Canada Drive 520-229-4811 pkeesler@orovalleyaz gov From: RonStaubAssociates [mailto:rsa@Comcast.net] Sent: Thursday, June 05, 2008 3:23 PM To: Ronquillo, David Cc: dkaws@orovalleyaz.gov; Keesler, Paul Subject: RE: OV12-05-06, Monte Del Oro Lot 187 split Dear David --- Thank you for the informational e-mail below. Many items are as decided upon at our recent meeting. However, it was my understanding that the revised Site/Grading Plan without a specific building would be required and would serve as a Preliminary Plat. This was determined due to the fact that no public street improvements are required. That is what we are preparing. However, now you (OV Staff) have added the requirement of Standard Preliminary Plat notes and signature blocks, required landscaping, all-weather driveway requirements, etc. which in my mind makes it a full-blown Preliminary Plat. That is far beyond what we agreed on. Not to be disagreeable, but here again what we discussed during the meeting is not what is now being requested. David, it seems like I am always hearing something different in the meeting from what eventually comes down in written form. It appears that since this is not a "normal" development project, everyone on staff has a different idea of what should be required and somehow adds their unique ideas into the mix to try to make it look like a normal project. Bottom line is that this is completely different than what was originally requested because as new staff are brought in, each person has a different concept of how it should work. (Sorry if I sound frustrated, but I am.) We need to discuss this again and try to once again come to an agreement. I don't want to bring the developer/owner into it, but to say the least, he is getting frustrated as we seem to keep getting caught in these endless loops.

I didn't think anybody had been in contact with you. After discussing the outstanding items with Paul Keesler and David Laws, the following will need to be achieved: 08/25/2008 Page 3 of 3 1. You will need to complete the site plan, which will act as your Preliminary Plat/Improvement Plan. This plan and supporting documentation needs to delineate the following: • Requested property line change with just basic dimensional control • Grading Plan that shows the building pad as well as the access (i.e. the driveway out to Lambert). o You also need to show the drainage patterns, particularly the area where the driveway intercepts the Lambert ROW flow (I.E. a small culvert or a dip section if the hydrology is less than 6" deep over the drive). The driveway must be all-weather access. o Demonstrate that the building pad is V higher than the 100yWSEL of the adjacent floodplain, at the north end of the building pad. • Delineate the floodplain • Show all easements from the title report. • Show any required landscaping • Delineate the required building set -backs • Provide the accompanying drainage report/work • Standard Preliminary Plat/Improvement Plan notes • Signature blocks for both Planning & Zoning for the preliminary plat and one for the Town Engineer for the improvement plan portions respectively. Once #1 is approved by staff, then we can proceed with step 2. 2. Final Plat. The following must be included in the final plat: • Property line surveyable metes & bounds • Floodplain with surveyable metes & bounds • All easements from the title report. • Any new easements (i.e. public water, drainage, etc.) • Standard Final Plat notes and format The site plan prepared for this project will act as the Preliminary Plat/Improvement Plan. Staff has reviewed this plan and has offered comments in the past, there are standard notes and details that need to be included as well as the new grading you need to revise because the drainage easement is no longer available. After all the comments on the Preliminary Plat/Improvement plan (aka site plan) are addressed, and the comments of the Final Plat are finished, then staff will approve the PP/IP and move forward with the Final Plat to mayor & Council. If you have specific questions regarding the engineering items please contact David Laws. Thanks, David Ronquillo 08/25/2008 FHw.A. STATE PROJECT N0. Ows TOTAL AS NALT REGION NO.

This application is true and correct to the best of my knowledge. I am the owner of the above described property or have been authorized by the owner to make this application. Date Signature TRIMBLC- ENGINEERING SERVICES, 2798 W. Appaloosa Road Tucson Arizona 85742 (520) 307-0300 Town of Oro Valley Public Works Department 11000 N. La Canada Drive Oro Valley, Arizona 85737 Re: Lot 187 Monte Del Oro Estates -Parcel No. 224 27 2990 Gentlemen/Ladies: This correspondence is being sent on behalf of the owner of referenced parcel Mr. James Hunsberger as my determination of the Hydrologic Concerns in regards to the possible splitting of the parcel. A summary of my findings is a follows. As per the recorded subdivision plat ( 27/99) for Monte Del Oro Estates, the majority of the lot is within the 100-year Flood prone Area. Please refer to a copy of the referenced plat. A home has been permitted and is currently under construction at the northwest comer of the lot and is not within the platted 100-year floodplain. Per information provided by the Town this platted 100-year flood prone area is not within a FEMA designated 100-year floodplain. Using the Pima County GIS Data, with 2 foot contour intervals it was determined that the Off -Site Watershed contributing to this 100 year flood prone area is 119 acres in size. The watershed extends northerly from the parcel approximately 6100 feet to the north, please refer to the attached Off -Site Watershed Map. Using the City of Tucson Method, it has been estimated that this watershed will produce a 100-year peak discharge of 452 cubic feet per second, please refer to the attached data sheet for additional information. Using the Site Topography that was part of the Grading Plan for the referenced house under construction, 3 three cross -sections were taken to determine the 100-year water surface elevations and hydraulic data at these locations. Please refer to the attached plan for the specific locations of these cross -sections. Using a Manning's Rating program the following data was determined. CROSS-SECTION 100 Yr WSEL DEPTH VELOCITY FROUDE NO. A -A 2516.89 0.89 ft. 3.75 fps 0.90 B-B 2513.21 0.61 ft. 2.86 fps 0.84 C-C 2509.39 0.39 ft. 2.73 fps 0.83 Please refer to the Attached Data Sheets for additional information on these cross -sections. Page 1 of 2 The 100-year flows across this parcel are quite shallow, less than 1 foot and the velocities are low and the flow as been determined to be sub -critical. Therefore, it is my Professional opinion that the parcel could be split and an additional home site could be designed on the eastern portion of the lot, without adversely impacting the upstream or downstream properties adversely. Once the exact size and location of the proposed home site is know additional hydraulic analysis should be accomplished to assure that these conditions are met and the 100 year water surface elevation is not increase by more than 0.10 feet Please let me know if you any questions or need any additional information.

Smzn-CRY xMiORIZATION: nie Legislature of the State of Arizona has, in ARS Section enabled the Town to adopt regulations in conformance with ARS Section 45 2349 designed to pramote ._. the public health, safety, and general welfare ofits citizen. Therefore, the Town Council of the Town of Oro Valley, , Arizona, ordain as follows: Sec. 202. FINDINGS OF FACT: 1. The flood hazard areas of the Torn of Oro Valley area sub?ect to periodic inundation which results in loss of life a�1r'o� services' arxi safety hazards, disruption of _ extraordinary public expenditures for flood protection and relief, and - impairment of the tax base, all of which adversely affect the pub lic health, safety and general welfare. 2. These flood losses are caused by the emulative effect of Obstruction -. -- in areas of special flood hazards which increase flood heights and .. -. velocities, and when inadequately anchored, damage uses in other areas Uses that are inadequately flood -proofed, elevated or otherwise protected from flood damage also contribute to the flood loss- 3 ...,,_ - --- 't Sec. 203. STAZEMERr OF PURPOSE: It is the purpose of this Ordinance to promote the public health, safety, and general welfare, and to minimize public and private losses due to flood conditions in specific areas by provisions designed: 1. To protect human life and health; 2. To minimize eXpenditure of public money for costly flood control projects; 3. To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; 4. To minimize prolonged business interxuptias; 5. To minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in areas of special flood hazard; 6. To help maintain a stable tax base by providing for the second use and development of areas of special flood hazard so as to minimize future flood blight areas; 7. To insure that potential buyers are notified that property is in an area of special flood hazard; 8. To insure that those who occupy the areas of special flood hazard assume responsibility for their actions; and 9. To maintain eligibility for State disaster relief. Sec. 204. NEMODS OF REDUCIM FIfJOD IOSSFS: In order to accomplish its purpose, this ordinance includes methods and provisions for: 1. Restricting or prohibiting uses which are dangerous to health, safety, and property due to water or erosion hazards, or which result in damaging increases in erosion or in flood heights or velocities; 2. Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damages at the time of initial construction; 3. Controlling the alteration of natural flood plains, stream channels, and natural protective barriers, which help accc¢odate or channel flood waters; 4. Controlling filling, grading, dredging, and other development which may increase flood damage; and, 5. Preventing or regulating the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards in other areas. 4 ARTICLE III Sec. 301. This ordinance shall apply to all regulatory flood plain areas within the Corporate Limits of the Town of Oro Valley. - Sec. 302. When not inconsistent with the context, words used in the --- present terLse include the future, words in the singular number include the r plural and words in the plural number include the singular; the word" bji i 1 c�� n includes the Word "structure;" the Word 11 shall" is _ mandatory and the word "may" is permissive.

An equal degree of encroaciment is a standard aPPlied to the evaluation of the effects of the encroachment on increases in flood heights. It assumes that an encroackanent if permitted may confer on all property owners on both sides of the wage an equal right to encroach to the same degree within that reach. since the factors affer_ i hydraulic efficiency are usually not uniform within a reach this staix3ard will usually not result in equal measured distances between floodway limit lines and the regulatory floodplain boundaries of the watercourse• g• "Exist' Manufactured Home park or division" means a manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including, at a miniMM, the installation of utilities, the construction of streets and either final site grading or the pouring of concrete pads) is cxopleted before the effective date of the floodplain management regulations adopted by a cc==-ity. 9. "Expansion to an Existing Manufactured Home park or Subdivision" means the preparation of additional sites by the construction of facilities for servicing the lots on which the manufacture homes.., are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads)•--�-- 10. "Flood" or Flooding" means a general and temporary condition of .�... partial or complete inundation of no= ally dry land areas from: (1) Zhe overflow of flood waters and/or (2) The unusual and rapid accumulation of runoff of surface waters from any source- 11.

The limits are established by assuming that the area landward (outside) of the floodway lines will be ultimately developed in such a way that it will not be available to convey flood flows. If hydraulic efficiency of the floodway is maintained by protecting it against unnecessary encroadumnts, it will be adequate to convey the regulatory flood resulting in an increase in flood elevation of more than on (1) f <,- 1/, oor- A = o. _--1. "Floodwav Fringe Area" means land outside the floodway and below the regulatory flood elevation. 22.

It is representative of large floods kx�to have occurred generally in the area and reasonable characteristic of what can be expected to occur on a particular watercourse. ,he regulatory flood generally has the probability of a 1% chance of being equalled or ooceeded in any given year. Said flood shall be determined fran analysis of floods on a particular watercourse and other watercoursesin the same general region in accordance with the criteria established by the Arizona Director of Water Resources, which criteria is hereby incorporated by reference and made a part of this ordinance. 34. Regulatory Flood Elevation: The water surface elevation of the regulatory flood. .P35. Regulatory Floocplain: Zhat portion of the floodplain that would be inundated by the Regulatory Flood and those areas which are subject to sheet flooding. 36. Retention Swstem• A type of flood control system which stops the downstream progress of flood waters by employing methods of total containment which generally involve creation of storage areas whin' incorporate infiltration devices, such as dry wells, to dispose of stored waters, principally by percolation over some specified period of time thereby eliminating basin contributions to downstream flood peaks or flood volumes. 37. Sheet Floodirx;: moose areas which are subject to periodic flooding with depths of one (1) foot or greater where a clearly defined channel does not exist and the path of the flooding is often unpredictable and indeterminate. on areas covered by Flood Insurance Rate Maps, these areas are designated as AD Zones. 38. Special Use permits; An official document which authorizes special activity within the Regulatory Floodplain. 39. Start of Construction: means the first placement or permanent construction of a structure (other than a mobile home) on a site, such as the pouring of slabs or footings or any work beyond the stage of excavation. Permanent construction does not include land preparation, such as clearing, grading and filling, nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers or foundations or the erection of temporary forms. For a structure (other than a mobile home) without a basement or poured footings, the "start of construction" includes the first permanent framing or assembly of the structure, or any part thereof, on its piling or foundation. W For mobile homes not within a mobile home park or mobile hone subdivision, "start of construction" means the affixing of the mobile home to its permanent site. For mobile homes within mobile hone parks or mobile hone subdivision, "start of construction: is the date on which the construction of facilities for servicing the site on which the mobile hone is to be affixed (including, at a minimum, the construction of streets, either final site grading or the pouring of concrete pads, and installation of utilities) is ccupleted. 40. "Substantial Damage" means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged conditions would equal or exceed 50% of the market value of the structure before the damage occurred. 41. "Substantial Improvement" means any reconstruction, rehabilitation, addition or other improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure before the "start of construction" of the improvement. This tern includes structures which have incurred "substantial damage", regardless of the actual repair work performed. The term does not, however, include either: (1) Any project for improvent of a structure to correct existing violations of state or local health, sanitary or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions, or (2) Any alteration of a "historic structure", provided that the alteration will not preclude the structure's continued designation as a "historic structure". 42. Variance means a grant of relief frm the requirements of this ordinance which permits construction in a manner that would otherwise be .prohibited by this ordinance. 43. Watercourse: A lake, river, creek, stream, wash, arroyo or other body of water or channel having banks and beds with visible evidence of the flow or occurrence of flood water except such lake or ponds without outlet to which only one landowner is riparian; and any depression serving to give direction to a current of storm water where the drainage area above the same is one square mile or more in extent; provided that it shall, upon rule or order of the Floodplain Board, also include other generally and specifically designated areas where substantial flood damage may occur.

Larger floods may occur on rare - occasions or the flood height may be increased by non -made or natural causes, such as bridge openings restricted by debris. This ordinance does not imply that areas outside Floodway and Floodway Fringe Areas boundaries or land uses permitted within such areas will be free frcam flooding or flood damages. This ordinance shall not create liability on the part of the Town of Oro Valley or any officer or employee thereof for any flood _.. damages that may result fra reliance on this ordinance or any a&nn strative decision lawfully made thereunder. .0 « i r • •. �■ • r• a •• ■ r• • • •. Sec. 901: This ordinance uses a reasonable method of analyzing flood -- hazards which consist of a series of inter -related steps: 1. Selection of a Regulatory Flood which is based up on engineering 24 calculations which permit a consideration of such flood factors as • its emoted frequency of occurrence, the area inundated, and the depth of inundation. The Regulatory Flood selected for this ordinance is representative of large floods known to have occur.--ed in this region and which are reasonably characteristic of what can be expected to occur on the particular streams or watercourses subject to this off. It is in the general order of a flood which could be expected to occur on the average of once every 100 years (See Article 3). 2. Calculation of water surface profiles which are based upon a hydraulic engineering analysis of the capacity of the stream or watercourse channel and overbank areas to convey the Regulatory Flood. 3. Delineation of Regulatory Floodplain boundary lines within which the area is subject to inundation by the Regulatory Flood. 4. Ccmlxrtation of the Floodway required to convey this flood witt ut increasing flood elevations more than one (1) foot or to an extent which would cause substantial upstream or downstream damage to existing or reasonably anticipated future development. 5. Delineation of Flocdway boundary lines within which no cbstxu Lion is permitted which would cause such damage. 6. Delineation of Floodway Fringe Area, i.e. that area outside the Floodway but within the Regulatory Floodplain. 7. Within one hundred twenty (120) days after camletion of construction of any flood control protective works, the Regulatory Floodplain and Floodway in the areas affected by such works shall be re -defined. Sec. 902: As an aid in understanding and visualizing the effects of flood hazard areas and floodplain regulations, referral is made to the following illustrations which are on file in the office of the Pima County Floodplain Board, in the offices of the Pima County Planning and Zoning lion, and in the offices of the Pima County Engineer. Miele illustrations are accepted as part of the ordinance as long as they continue on file in the above Pima County offices. 1.

INTRODUCTION The subject Site is Lot 187 of Monte Del Oro Estates as recorded in Maps & Plats Book 27 at Page 99 and is located at the Northeast comer of Lambert Lane And Pecan Place. The Site is located within a portion of the Southeast Quarter of Quarter of Section 11, Township 12 South, Range 13 East, G & S R M, within the incorporated area of the Town of Oro Valley. The site is 3.96 acres in size and currently has a single family residence constructed at the northwest comer of the lot, that was recently completed. Please refer to the "Location Map", Figure 1. The objective of this Report is to provide calculations and analysis that support the splitting of the lot and construction of a single family residence upon the eastern portion of the site, together with the preparation of a Final Plat reflecting this Lot Split. This will be accomplished by determining the existing 100-year water surface elevations and then inserting a proposed house and performing an encroachment analysis conforming to the Town of Oro Valley Floodplain Management Ordinance. The Site is zone "R1-43% and per the Monte Del Oro Subdivision Plat, the majority of the Lot is located within a 100-year flood prone area. The Site is not located within any FEMA designated 100-year Foodplain. The site is approximately 1400 feet north of the Canada Del Oro Wash. Detention will not be required. Except for -the northeasterly portion of the site which has the existing home constructed upon it, the remaining undeveloped portion of the lot slopes from north to south at approximately 3%. -1- . 1 "iNt:er 2 %Z BG1�K _aiL_ PAGE - �f . � ' 6 �� DEDICATION 0 s0 • t IY bT..

EXISTING CONDITIONS DRAINAGE Off Site - Hydrology From the Pima County GIS Mapping and Site investigation it has been determined that an off -site watershed area of 119 acres (including this parcel) impacts this site. Please refer to Figure 2 Off -Site Watershed Map. This watershed area consists of Single Family Residences constructed upon R1-43 lots. The majority of this watershed is developed and it is believed that the existing run off and future will not significantly increase from the existing. The Soils Type for this watershed is 80% b, 20% D, using the Rational Method a 100- year Peak Discharge of 457 cfs was determined, (as a double check using the C.O.T. Rational Method a 100-year Peak Discharge of 452 cfs was established). In the upper reached of this watershed the flow is contained within an existing natural channel. As this flow reached this site it is widely dispersed in sheet flow that exits the site across Lambert Lane to curb openings and into an improved drainage channel along the south side of Lambert Lane. There are not any existing drainage studies for the project that/Site or adjacent sites that are impacted , or impact this site. On -site Drainage The Existing site is bisected by very shallow eroded drainage rivulets, which appear to be quite fluid and move with each storm event, which indicates shallow sheet flow across the site. The Site is not located within any FEMA designated 100-year floodplain. The site is approximately 1400 feet north of the Canada Del Oro Wash. -3- 1 4 ' w .&ZG4-' i �TBYf'M -- �' _ � � �,` `'�j2 �771•- .-. ri/ i7% ,f I ,t � w `}- � :{,. - �D ^.4 _1.. 2� ? ry _ter q"3 < 2758 2694., „"/ N-t I � � _� r�' nl -_. ?^ - _ � ',n ��� _ �0 } �r -.6 _•:2 �`i�ri rc 2664 76 z ,ta '` - � _ v'�" � t�� i� 269�• � r, .� � � `��' � �298� � c �2 r A� t", - w� n- 2b6L be^h ^,.:-� ,.�--+�•-�•--r1l ,o n G l:'r�.

PROPOSED CONDITIONS DRAINAGE DESIGN It is proposed to split the parcel into a West Parcel with the existing house that is 1.63 acres in size and an East Parcel of 2.34 acres in size that will have a proposed +/- 3800 square foot home constructed upon it. Please refer to Figure 3-Proposed Split for more specific information. Storm water detention is not required for this, however it is recommended that the Grading Design for the proposed house incorporate the use of water harvesting for the landscaping. The proposed split will not have an adverse impact upon any existing drainage concentration points or existing drainage facilities. It is proposed that the existing sheet flow discharge points remain after development of the East Parcel. -5- TAGGO NAIL IN AST DRIVTA 1 � _ EMI RSLOPE I C � m 1 :AI � t 1 � II i 1 O i 0 1 NI m v , ' a I /X I I m r ; ch r 1" 00 L M IN a 20' SIDEYARD SETHACK•1 �1H't1= 1100 LI SENENT NBI ¢E DS /ePARCEL A - % I \.

Also, compliance with the current United States Fish and Wildlife Service Endangered Species Act's list of threatened and endangered species will need to be supplied. In addition an SWPPP will need to be provided. I6� 5. HYDROLOGY AND HYDRAULIC ANALYSIS � Lro Ili Hydroloqv As previously stated a 100-year Peak Discharge of 457 cfs was determined for the combined off -site & on -site watershed, with this dispersing as sheet flow along the southerly property line of the site. Hydraulics Using Site Topography, that was field determined three cross -sections were taken to determine the existing 100-year water surface elevations and hydraulic information. This data was determined using a Manning's Rating Program (results in the Appendix). Please find the results for the existing Cross -Sections as follows: CROSS-SECTION 100-YR WSEL DEPTH VELOCITY FROUDE NO. A -A 2516.89 0.89 ft. 3.75 fps 0.90 B-B 2513.21 0.61 FT. 2.86 fps 0.84 C-C 2509.39 0.39 FT. 2.73 fps 0.83 These results show that the existing 100-year flow is fanning out and slowing down as it flows to the south across the parcel.

HYDROLOGY AND HYDRAULIC ANALYSIS -continued Hydraulics Inserting the proposed 3800 s.f. house on the East Parcel will modify only Section B-B, The construction of the house will result in a 100-year water surface elevation of 13.53 _, feet with a velocity of 3.80 fps. This is an increase of water surface elevation of 0.32 feet and an increase of velocity of 0.94 fps. The flow will be split along the sides of the proposed house and will rejoin prior to Section C-C. The water surface elevation and velocities at the upstream and downstream sections will remain the same, therefore this construction does not adversely impact the site, or surrounding parcels. Please refer to Figure 5-Developed Site Conditions. Because of the low velocities, erosion control will not be required and scour will not be a factor. Figure 5-Developed Site Conditions -10- 5. CONCLUSIONS The site as proposed do be developed will not adversely impact upstream or downstream properties and will meet the requirements of the Town of Oro Valley Drainage Design Manual and Standards. -11- APPENDIX Hydrologic Data Sheets Hydraulic Calculations -12- City of Tucson Hydrologic Data Sheet for Computing I00-Year Peak Discharge loo) I - Project Name and Location: Lrr 1121 — 110 Da L, Cj9.6 Z Z / co / L/ 2.

Box 6457 Phoenix, A2 85005-6457 JUL 15 2003 JUL Western Area Power Administration (Western) has reviewed the plans you submitted on behalf of the landowners. The plans depicted certain grading and a septic line crossing Western's transmission line right-of-way. Pima County Assessor's records indicate that James and Penelope Hunsberger are the owners of the land (Parcel No. 224-27-2990) underlying Western's transmission line easement across this area. The grading and septic line, as proposed, will involve Western's Oracle -Tucson 115-kV Transmission Line right-of-way in Section 11, Township 1.2 South, Range 1.3 East, O&SRM, Pima County, Arizona. The location of Western's structure (pole) was not depicted on your plans; therefore, research was conducted and the location of the pole calculated to be approximately 15 feet from Western's Structure No. 14-7, Since excavation is prohibited within 20 feet of Western's pole, we could not concur with the line crossing 15 feet from the power pole. Mrs. Marter, during a telephone discussion, assured me that the septic line would be a minimum of 50 feet from the nearest Western power pole. Our records will be documented to reflect the line crossing 50 feet south of Structure No. 14-7. As also discussed with Mrs. Matter, heavy line equipment must have ingress and egress along the right-of-way and to the structures or poles at all times. A. level, clear. -zone area (100-foot diameter) around the transmission line pole must be provided for maintenance purposes. Western will not be responsible for any damage caused to the septic line by the heavy equipment and Iarge vehicles used for routine maintenance and in emergency situations. The grading you propose will need to be restricted to the outside 15 feet of the westerly boundary of the transmission line right-of-way. The transmission line easement area is a restricted -use area; therefore, any additional grading, changes, or other proposed use must be reviewed and approved by Western. Other prohibited uses or improvements include, . but are not limited to, buildings, swimming pools, tennis courts, light poles, RV parking or storage, and similar structures. Trees must not be planted within the easement area. Any fences located across the right- of-way must have a dual -lock, 16-foot-wide gate at each end. Metal fences must be adequately and properly grounded. +.+V�. iV I...VVJ 1'f•JV 1 1\VI I• I U: bti 0dt58Jz4 P. 3%9 2 We are enclosing an original and duplicate -original License Agreement for signature by the landowners. Please note that the License lists other restrictions or prohibited uses of the transmission line night -of -way. The signed original and duplicate -original License Agreement should be returned to this office for further processing. We request the date on the License Agreement be left blank, as our Regional Manager will date the License at the time he approves and executes it. If both originals are signed and returned to this office, we will forward the fully executed original License Agreement to the landowners for their records. Should any additional service be required of Western on the proposed use of the right-of- way, a written request will need to be addressed to Ms. Jean Gray, Assistant regional Manager for Power Marketing, at the above address. A Letter Agreement will be prepared to provide the advanced funds for Western to perform the needed service. Both you and the landowners should be aware of the electrical hazards involved in construction operations under or near an energized line. All equipment should be properly grounded, and the minimum clearance must be maintained at all times between the conductors and any construction equipment. If you have any questions or require additional information, please contact me at (602) 352- Jo Penunuri Realty Specialist Enclosure UNITED STATES OF AMERICA DEPARTMENT OF ENERGY WESTERN AREA POWER ADMINISTRATION Oracle -Tucson .115-kV Transmission Line 1 r Section 11, Township 12 South, �l���-'1 - Range 13 East, G&SRM, Pima County, Arizona ` JUL Between Structures 14-7114 +' LICENSE AGREEMENT THIS LICENSE AGREEMENT, made this day of _, 2003, between James A. and Penelope Hunsberger, 10408 North Pecan Place, Oro Valley, Arizona 85737, (LICENSEE), whether one or more, and the UNITED STATES OF AMERICA, Department of Energy, Western Area Power Administration (Western), represented by the officer executing this Agreement, pursuant to the Reclamation Act, Act of June 17, 1902,32 Stat. 388, and acts amendatory thereof and supplementary thereto, and the Department of Energy Organization Act, Act of August 4, 1977, 91 Stat. 565.

With this said, when you and I last spoke, you relayed to me that the actual building configuration is undetermined at this time. In fact your client may sell the lot to someone else to develop. The building pad can be generic (i.e. a square larger than what you expect a reasonable residence would encompass). The most important thing that will be gleaned of the plan is that there is adequate FFE with respect to the adjacent floodplain and the ability to get a reasonable connectivity (i.e. slope) in the driveway to Lambert Lane. I will coordinate this with David"& David. Paul Keesler, P.E. Development Review Division Manager Town of Oro Valley Department of Public Works 11,000 N.

Pecan Place (Section 11, T12S, R13E), Oro Valley, Pima County, Arizona. The enclosed aerial photograph delineates the waters of the United States, including wetlands, regulated by Section 404 of the Clean Water Act. This approved jurisdictional determination will remain in effect for five years from the date of this letter unless an unusual flood event occurs. After this five- year period or after an unusual flood event alters stream conditions, the Corps of Engineers reserves the authority to retain the original jurisdictional limits or to establish new jurisdictional limits as conditions warrant. Each water of the United States herein delineated is an interstate water or a water that is tributary to an interstate water. The Section 404 jurisdictional limit for a water of the United States is defined at 33 CFR Part 328. The jurisdictional limit for a non -tidal water of the United States is determined by the jurisdictional wetland boundary and/or the ordinary high water mark. The jurisdictional limit of a wetland is determined in accordance with the Corps of Engineers 1987 Wetlands Delineation Manual. Otherwise, presence of the indicators stated in the definition of ordinary high mark (33CFR 328.3(e)) are used to establish the jurisdictional limit of a water of the United States. The basis of this jurisdictional determination is shown on the enclosed checklist. Any discharge of dredged or fill material within the designated jurisdictional area requires a Section 404 permit from the Corps of Engineers. The Corps of Engineers emphasizes avoidance of the delineated jurisdictional area. Please review this delineation and evaluate your proposed activity to ensure that avoidance of the jurisdictional area is given full consideration in your design. If all discharges of dredged or fill material occur outside the designated jurisdictional area, no Section 404 permit is required. If avoidance is not practicable, please reference File Number 2006-00457-MB when submitting your Section 404 permit application to the Corps of Engineers. Please be advised that your application needs to substantiate that avoidance of designated jurisdictional areas is not practicable and substantiate that impacts to waters of the United States have been minimized.

Development Review Manager Public Works Department Town of Oro Valley Oro Valley, Arizona 85737 RE: Drainage Report Addendum for Monte Del Oro, Lot 187, Parcel 224-27-2990, 10408 N. Pecan Place — OV12-05-06 Dear Mr. Keesler: In March 2006, JE Fuller (JEF) was retained to prepare a drainage report addendum for the above - referenced project that addressed Craig Civalier's comments dated May 20, 2005 (copy attached). Since the comment letter was almost a year old, as were all the comment letters from the Town regarding this project, meetings were held on April 25, 2006 and August 3, 2006 to discuss the resubmittal requirements. After the August 3`d meeting, Jill Manion -Farrar, a Town planner, summarized the requirements in a letter to Lyle Marter dated August 10, 2006. The only reference to the drainage requirements was Craig Civalier's letter to Tom Trimble of Trimble Engineering. However, the outcome of those meetings also resulted in the following revisions to Mr. Civalier's comments. • Comment 2 —This comment was no longer applicable since the results of the HEC-1 analysis prepared by Entranco for the Lambert Lane improvement project (OV 30-99/00-07) could be applied to this project. Comment 3 — Additional cross sections downstream of Lambert Lane would not be needed since the existing (without -project) and the proposed (with -project) HEC-RAS models could assume that the Lambert Lane improvements were constructed. This assumption provides the most conservative starting water -surface elevation for the two models, since a box culvert will be constructed beneath the new elevated roadway section and a berm/collector channel will be used to capture and convey flow to the inlet. • Comment 4 — Since the topography used for the Lambert Lane improvement project was more detailed than the mapping prepared by Trimble Engineering, the Lambert Lane topography could be used for the more -detailed HEC-RAS analysis. • Comment 5 — This comment is no longer applicable, since Section A -A is not part of the revised analysis. Those comments that are still applicable (i.e., Comment 1, the majority of Comment 3, and Comment 6) are addressed as follows: 8400 S. Kyrene Rd., Suite 201 2160 N. Fourth Street, Suite 202C 40 E.

A new location map and a 2005 aerial photograph of the project site are provided as attachments to this letter. In addition, a revised grading/site plan for the project was prepared by Ron Staub of Ron Staub Associates. A portion of the revised plan is also provided as an attachment to this letter. 3. The relevant information from Entranco's hydraulic analysis of the watercourse impacting the project site, including their floodplain map, is included as an attachment to this letter. The regulatory flood plain shown on their map was delineated using the headwater elevation from the proposed box culvert at Lambert Lane and the results of a normal -depth analysis of two topographic cross sections (Sections 9A and 913). The HEC-RAS analysis JEF conducted included eight (8) topographic cross sections. The locations of the cross sections are shown on the attached existing -conditions Floodplain Map. The first cross section was located at the inlet to the proposed Lambert Lane box culvert and the last cross section was located just upstream of the northern boundary to Lot 187. Based on the results of the more -detailed HEC-RAS analysis, the existing 100-year floodplain boundary is approximately the same as the boundary defined by Entranco (e.g., Entranco's water - surface elevation at Section 913, which corresponds to Section 6, is 2515.25, and the corresponding value at Section 6 is 2515.34). Using the site plan provided by Ron Staub Associates, the existing -conditions model was revised to reflect the proposed encroachment, which consists of an onsite/offsite berm and the fill pad associated with the building envelope (see the attached developed -conditions Floodplain Map). The results of the existing and developed conditions HEC-RAS analysis are summarized in the following tables. The HEC-RAS input/output listings are provided as an attachment to this letter.

Mr. Paul Keesler, P.E. — RE: Drainage Report Addendum - OV 12-05-06 May 4, 2007 Page 3 Based on the results of the encroachment analysis, the maximum increase in the water -surface elevation is 0.18 feet. However, this increase, which occurs at Section 6, is confined to the boundary of Lot 187. The maximum offsite increase is limited to 0.08 feet. The maximum change in the flow velocity is 0.46 feet per second (fps). The average flow velocity adjacent to the proposed berm is 3.08 fps. Per Pima County's Technical Policy document TECH-006 for dumped rock riprap (copy attached), the minimum D50 size of the rock is 6 inches and the minimum layer thickness is one foot. The minimum toe -down depth will be three (3) feet. A scour analysis conducted using the procedure outlined in the City of Tucson Drainage Standards Manual was used to confirm that the minimum toe -down depth would be adequate. The computed scour depth was 1.5 feet; therefore, the minimum depth from TECH-006 was deemed adequate. A copy of the scour computation sheet is included as an attachment to this letter. 6. A copy of the Section 404 Jurisdictional Delineation exhibit prepared by the U.S. Army Corps of Engineers in March 2006 is provided as an attachment to this letter. The minimum finish -floor elevation was determined using an interpolated water -surface elevation relative to Sections 5 and 6. The upstream limit of the proposed structure is approximately 22 feet upstream of Section 5. In the vicinity of the structure, Sections 5 and 6 are separated by approximately 61 feet. The interpolated water -surface elevation for developed conditions was determined to be 2514.23. Therefore, the minimum recommended finish -floor elevation is 2515.23. Although the preliminary site plan shows a finish -floor elevation (FFE) of 2515.0, the final site plan will be revised accordingly. If you have any questions, regarding the results of our analysis or our response to Craig Civalier's comments, please feel free to contact me at your convenience.

Erosion Protection of Fill Pads in F000dway Fringe Areas PURPOSE: To clarify 16.26.040.13 regarding the protection of the fill pads from erosion in order to establish consistent permitting requirements that are sufficiently protective of the fill pad and structure for the flood hazards that have been identified. BACKGROUND: The Floodplain and Erosion Hazard Management Ordinance (2005-FC2) provision 16.26.040.13 requires that any fill placed in a floodway fringe be adequately protected from erosion by rip -rap vegetative cover, bulk -heading, or other approved method, but does not establish appropriate levels of erosion protection based on the hazards that may be encountered due to the lateral forces of moving water. In addition, Ordinance provision 16.25.050.F requires that fill pads extend to a distance 25 feet from the edge of the structure, but does not specify methods of erosion protection. Historically, the need for erosion protection has not been addressed at the time of permitting and therefore, erosion protection has not been provided. The following publications discuss fill pads and/or erosion protection: 1) The FEMA publication, Manufactured Home Installalion in Flood Hazard Areas, FEMA85, published in September 1985, prescribes: a. A minimum of 25 feet of fill beyond the perimeter of the structure, which is consistent with the Ordinance. b. Vegetative cover as erosion protection when velocities are 5 fps or less, rock rip -rap for velocities between 5-10 fps, and prohibit fill pads in areas of greater velocity. 2) The 2005 draft of FEM485 prescribes: a. A reduced fill pad dimension of 5 feet or twice the fill pad height (from 25) from the perimeter of the structure. b. Limitations on the use fill pads where it will constrict floodplains and cause significant increases in flood heights or velocities 3) The City of Tucson Drainage Standards Manual, specifically Chapters 6 and 9, provides methods to determine erosion/scour depths, and rip -rap sizing. a. The scour equation in Chapter 6 includes the effects of local scour due to obstructions of flow, such a fill pad. The applicable portions of the scour equation will be used in estimating potential scour. b. The rip -rap sizing chart is intended for use in channel design, and indicates the need for rip -rap at velocities less than 5 fps. This use of this chart is intended to augment the FEMA85 documept when applied to fill pads. 4) The Pima County Drainage and Channel Design Standards Manual, and the Grading Design Manual provide additional criteria for the design of erosion protection of channels based on flow velocity, and cut and fill slopes. The criteria include riprap sizing, side slope steepness, toe down depth, and maximum height requirements. The COT Drainage Manual and the Pima County Drainage and Channel Design Standards Manual indicate that erosion protection in addition to vegetative cover is needed at approximate flow velocities of 2.5 fps and greater. Because they are more restrictive than FEMA85 and more representative of the Arizona soil and hydraulic conditions, these documents will be used for this policy However, the COT Drainage Manual Equation 6-3 is an additive equation that establishes a total potential scour based on a variety of scour components. Since some of these components are not applicable for fill pads in broad floodplains, this policy may establish design criteria that is not as restrictive as the equation. In addition, in order to efficiently and effectively address the need for minimum erosion protection standards across a wide variety of flow regimes, RFCD has chosen to apply minimum standards categories using ranges of flow depths and flow velocities. The criteria from these publications and calculations are used as the basis for this policy. POLICY: If the fill pad encroaches into an Erosion Hazard Setback, is in a study area that establishes a requirement for an engineering analysis, or if RFCD determines that, due to unusual conditions, engineering is required, the engineering analysis requirements supersede this policy. 'File following policy shall apply in floodplain areas outside of Erosion Hazard Setbacks or other areas requiring engineering: I ) In all cases, the fill pad shall be constructed at or above the BFE for at least 25 feet outside the perimeter of the stricture, and the side slopes shall be no steeper than 3:1 (from both Channel and Grading Standards). if engineering analysis is provided that justifies a reduction, the engineering analysis shall draw conclusions regarding the level of protection needed and this policy is not applicable. 2) The attached table, which establishes 4 minimum erosion protection standards, shall be used when this policy applies. The description of each standard is as follows: a. No additional erosion protection other than vegetation is required (Green category): This category applies when flow velocities are less than 2.5 feet per second, and generally applies in sheet flooding areas, AH Zones, Shaded X Zones, AOI Zones where the slope is 1% or less, or where maximum velocities at the fill pad'are known and are less than 2.5 fps. The applicant shall specify the type and quantity of vegetation on the site plan. Fill pad protection must be placed along the entire length of all sides that experience flood flows and must completely surround any fill pad that is surrounded by floodwaters. 3) b. Additional protection consisting of 6" rip -rap, with 3 foot toe down (Yellow category): This category applies when flow velocities are 2.5 to less than 4.0 feet per second, and generally applies in AO Zones where the slope is more than i %, AO2 Zones where the slope is 1 % or less, or where maximum velocities at the fill pad are known and are between 2.5 and 4 fps. The applicant shall specify that the fill be protected by the use of geo-textile filter fabric underlying angular rock rip -rap with a 1350= 6", a minimum thickness of 12", and a minimum toe -down depth of 36". Fill pad protection must be placed along the entire length of all sides that experience flood flows and must completely surround any fill pad that is surrounded by floodwaters. The toe -down depth can be accomplished by either extending the rip -rap into the native soil at the same slope to the appropriate depth or by using a 12" thick vertical cut-off wall constructed where the rip -rap meets the natural grade. See fill pad detail (Attached). c. Additional protection consisting of 9" rip -rap, with 4 foot toe down (Orange category): This category applies when flow velocities are 4.0 to less than 5.5 feet per second, and generally applies in AO2 Zones where the slope is more than 1% but less than 2%, or where maximum velocities at the fill pad are known and are between 4:0 and 5.5 fps. The applicant shall specify that the fill be protected by the use of geo-textile filter fabric underlying angular rock rip -rap with a D50= 9", a minimum thickness of 18 and a minimum toe -down depth of 48". Fill pad protection must be placed along the entire length of all sides that experience flood flows and must completely surround any fill pad that is surrounded by floodwaters. The toe -down depth can be accomplished by either extending the rip -rap into the native soil at the same slope to the appropriate depth or by using a 12" thick vertical cut-off wall constructed where the rip -rap meets the natural grade.See fill pad detail (Attached). d. Engineering analysis required (Purple category): This category, applies when flow velocities are 5.5 feet per second or greater. Any fill pad proposed in these areas shall have an engineering analysis that establishes adequate protection from scour and shall include, at a minimum rip -rap size, thickness, and minimum toe down depth When an engineering analysis is required for this and/or other reasons, including Erosion Hazard Area reduction, encroachment analysis, based on Special Studies or for unusual conditions the engineering analysis also shall prescribe the minimum erosion protection and this policy is not applicable. f APPROVED BY: -5�- i Suzanne hieids Directo Da{e( Original Policy Approved: Date(s) Revised: ); RIPRAP AND TOE -DOWN REQUIREMENTS FOR EROSION PROTECTION OF FILL PADS IN FLOODWAY FRINGE AREAS PIMA COUNTY REGIONAL FLOOD CONTROL DISTRICT TECHNICAL POLICY TECH-006 P fJU7 NOTES. n = manning's roughness coefficient for overbank flow per Table 8.1, SMDDFM Drg = 0,180 Lnchas Dia of soil particle for which 75 % of fill pad material is smaller (Default if no info available is 4 mm = 0.157 inches Dso , 0,039 fthes Dia of soil particle for which 50 % of fill pad material is smaller (Default if no Info is available is 1 mm = 0.0394 inches) h = 38.5 dog("* angle of repose of fill material per Figure 7.8, SMDDFM a, _ 25 ft length of embankment projecting into sheet flow Z = 3 , 1 slope of embankment (Z = 2 or 3 only for riprap, 1.5 < Z < 4 for allowable velocity calculations) < _ 45 degrees angle of impingement of flow on the embankment slope, ft/ft 0.002 0.004 0,006 0,008 0.010 0,012 0.014 0.016 0,018 0.020 0,022 0.024 0.026 0.028 0.030 r ow 100yr Flow Depth, It 100•YR NORMAL FLOW VELOCITY FOR BROAD, FLAT FLOODPLAIN AT INDICATED SLOPE AND FLOWING AT INDICATED DEPTH mannin 's equ.), fps Depth, ft 0,50 2.53 2 52 2:. 0.50 1.00 2.71 2,93 3.13 3 32 3 50 3 67 3 84 3 QJ 4 14 4.29 1.00 1.50 2,89 3.24 355 3.83 409 434 458 4.80 5 01 522 5.42 5.61 1.50 2.00 3.03 3 50 ' 9 , 4 29 463 495 5.25 5,53 5.80 6,06 6.31 6.55 6.78 2.00 2.50F3.23 2.87 3.51 4 Cie,4 53 4.97 537 5.74 6.08 6.41 673 7.02 7.31 7.59 7.85 2,50 3.00 3.96 4.57 511 5.80 6.05 6.47 6.86 723 759 7.92 8.25 8.56 8:88 3.00 slope, ft/ft 0.002 0.004 0.006 0.008 0,010 0.012 0.014 0,016 0,018 0,020 0.022 0.024 0.026 0.028 0.030 ept 100yr Flow 7ow ft TOE -DOWN DEPTH a u. 6-3SMDDFM , ft Depth, ft 0.50 1 1 1. 0.50 1.00 t :. 2.6.1 2.72 2.80 2.87 2.94 3.00 3,06 yi 1 ;: 3118 1.00 1.50 3.19 3 35 348 3 60 3111 382 3.92 401 4 10 4 18 4.27 4,35 1.50 2.00 3.67 389 4.09 4. 216 4.41 4 _56 4,69 4 S2 494 5,06 5.17 528 5.39 2,00 2,50 3.94 4,27 4 ; e 478 4 96 5 17 5.35 552 5.66 583 5,97 6,12 6.25 639 2.50 3,00 4.46 4.85 516 5-43 5.88 5490 6,11 6,31 6,50 6.68 6,86 703 719 7,35 3.00 slope, tuft 0.002 0.004 0,006 0.008 0.010 0.012 0.014 0.016 0.018 0.020 0.022 0.024 0.026 0.028 0.030 Flow Depth, 100yr Flow ft ANOUALR RIPRAP D S.G : 2.65; fig. 91, SMDDFM , ft Depth, ft 0,50 0.19 0.21 3.21 0.50 1.00 0.22 0.26 0.30 0.34 0,38 0.42 0.48 0,50 AS ?
