The project , entails subdividing an existing 5.38 acre site consisting of6 buildings andparkingJot around its perimeter. Access exists from Loker Avenue via a driveway in the Northbound direction. 'Please refer to the Vicinity Map (next page) for the approximate project location. The scope of this project is to detennine the flow rates contributing to each of the three existing catch basins / inlets on site and the appropriate water quality devices to be selected based on the calculated Qs. There will be no construction activities taking place on the project. National Pollutant Discharge Elimination System NPDES requirements are contained in Section 402(P) of the federal Clean Water Act. These requirements are implemented through permits issued by the State Water Resources Control Board (SWRCB) or the local California Regional Water Quality Control B..)ard (CRWQCB) in which the project is located. These requirements are discussed in further detail within Section 3.0 of this report. This project is exempt from permanent storm water requirements as defined by the Municipal Storm Water Permit. Section F.l.b.(2)(a) Qfthy Municipal Pennit states that projects adding or creating at least 5,000 square feet of impervious surfaces on an already developed site are subject to SUSMP requirements. This project proposes no improvements and thus no new impervious surfaces. This preliminary technical report is intended to comply with the City of Carlsbad requirement to provide a Stonn Water Management Plan with application submittals. BMP options, flow calculation and maintenance requirements are provided, however it is emphasized that per the California Regional Water Quality Control Board Municipal Permit this project should not be subject to the requirement for these water quality treatment devices.

Board, San Diego Region is the State Agency· tasked with regulating storm water discharges in the City of San Di<;:go, the County of San biego, the Port of San Diego, and 17 other cities in the region (hereafter referred to as . Copermittees). On February 21,2001 the Regional Board adopted a new Municipal Storm Water Permit, Order No. 2001-01 (Municipal Permit). This Municipal Permit coupled with the existing Statewide General Construction Permit, Order No. 99-08-DWQ, places greater requirements on new development. The Municipal Permit requires municipalities to develop and implement Jurisdictional Urban Runoff Management Programs (JURMP). The JURMp contains several components. These components include: • Land-Use Planning for New Development and Redevelopment • Construction • Existing Development • Education • Illicit Discharge Detection and Elimination • Public Participation • Assessment of Jurisdictional URMP Effectiveness • Fiscal Analysis The Land Use Planning for New Development and Redevelopment Component requires each Copermittee to modify their development project approval processes. Prior to project approval, Copermittees are tasked with conditioning each proposed project to implement measures that ensure pollutants and runoff from the development will be reduced. This reduction of pollutants is accomplished through the development ofproject requirements in local permits. These conditions include specific requirements for project proponents, such as: • Implementing source control B<;:st Management Practices (BMPs) for all applicable development projects; Prepared By: Rick Engineering Company 3 August 29,2003 ST:rh\R:\d_14437\Report\SWMP (001 ).doc I I I I I I I I I I I I I I I I I I I • Implementing site design/landscape characteristics which maximize infiltration, provide . retention, slow runoff ~d minimize impervious land coverage. for all development:projects; and • Providing proof of a mechanism which will ensure on going long-term maintenance of all structural Post-Construction BMPs Another constituent of the Land Use Planning for New Development and Redevelopmem.t Component of the Municipal Permit requires Copermittees to provide SUSMPs to reduce pollutants from all new c1evelopment and significant redevelopment projects falling under specific priority project categories or locations. The SUSMP includes the use of structural treatment BMPs. These BMPs should be located to infiltrate, filter or treat a required volume or flow prior to its discharge to any receiving water body supporting beneficial uses. This volume or flow based BMP treatment is known as Numeric Sizing Criteria. The San Diego Final Model Standard Urban Storm Water Mitigation Plan (San Diego SUSMP) developed by the Copermittees and approved by the SDRWQCB on June 12,2002 provides an implementation guide for compliance with the Municipal Permit.

Pesticides may pose problems when. excessive applications containing toxic levels of its active component result in runoff While the site is not expected to generate a large volume of sediment since no construction activities will take place, some sediment will be tracked in by cars and a small amount may be generated on site. This sediment is defined as a pollutant, and may also contain attached polhltants such as heavy metals. The majo:i.ty of these typical pollutants will be transported by low flows occurring during the initial stage of a storm event. Pollutants of Concern in Receiving Waters According to the "Water Quality Control Plan for the San Diego Basin (9Y', dated September 8, 1994, the Lot 21 property is within the Agua Hedionda Hydrologic Subarea of the San Marcos Hydrologic Area within the Carlsbad Hydrologic Unit. The corresponding number designation is 904.51 (Region '9', Hydrologic Unit '04', Hydrologic An~a '5', Hydrologic Subarea '1 '). Existing condition collects runoff in a drain network that will discharge into Agua Hedionda Creek. Agua Hedionda Creek drains west into Agua Hedionda Lagoon and ultimatelY:drains into the Pacific Ocean. Lot 21 does not discharge directly into any impaired water bodies and the property is therefore not subject to the requirements of a 303(d) listings.

The Stom Water Standards manual indicates projects shall incorporate the following BMPs into the project design: Site Design BMPs Source Control BMPs BMPs for Individual Priority Project Categories (these are site design and source control) Treatment Control BMPs In general, site design, source control, and category specific BMPs are non-structural; and treatment control BMPs are structural. A more detailed description of each type ofBMP is discussed below. Site Design Site design BMPs are designed to maintain or reduce pre-development erosion and protect stream habitat. Since the proposed subdivision will not result in any disturbance of the native vegetation, site design BMPs are not required for this project. However, the discharge within an existing storm drain network would be treated by structural treatment control facilities, which are discussed below. Source Control Source control BMPs are generally non-structural and are intended to reduce the quantity of pollutants entering the storm drain system. This can be accomplished by employing integrated pest management (IPM) principles that includes minimizing the use of pesticides on site, Prepared By: Rick Engineering Company 6 . August 29, 2003 ST:rh\R:\d_14437\Report\sWMP (OOl).doc I I I I I I I I I I I I I I I II I I I utilizing efficient irrigation systems to prevent runoff from landscaping, through public education (e.g., storm water conveyance system stenciling and signage, pollution prevention literature), as well as street sweeping. Public education is a preventative measure to reduce potential storm waterpollution at its source. Public education typically includes literature describing storm water pollution prevention, resources for reduction, and proper disposal techniques for potential storm water pollutants. Stenciled inlets are another form of public education that informs the general public that the storm drain system discharges directly into downstream water bodies~ The owner of a property subject to source control BMP's would be responsible for removal and disposal of waste material from the project site and maintaining landscaping on the project site in 'a manner that would prevent soil erosion and minimize sediment transport. Street sweeping physically removes sediment and trash from the roadways and parking areas to prevent it from entering the storm drain system. Site specific source control BMPs would be described in greater detail within the PCSWOMP as required for termination of coverage when under the General Construction Permit. Treatment Control Treatment control BMPs will treat, infiltrate, or filter a specified amo1,l11t of runoff from the project based on the numeric sizing criteria described in the Storm Water Standards manual (and the Municipal Permit Order No. 2001-01). The amount ofrunoffthat must be ,treated maybe calculated using either the volume-based criteria or flow-based criteria, depending on the type of BMP selected to meet this requirement. The Storm Water Standards manual provides several criteria for calculating treatment volume of runoff for volume-based BMPs' or treatment flow for flow-based BMPs. The following discussion of structural BMPs describes the treatment control BMPs which could be used to address the pollutants of concern associated with a project such as this.

Following are descriptions of Structural BMP options that could be used on a site such as Lot 21. In-line storm water treatment units (with absorbent booms added) are mechanical separatots that physically reduce sediment, trash, debris, and oil and grease from the flow and pesticides that attach to sediment. In-line storm water treatment units are installed after the last inlet to the storm water conveyance system and before the system connects to the existing off-site: storm drain system. In-line storm water treatm~nt units are flow-based BMPs. These BMPs would be incorporated to meet the requirements of the Storm Water Standards manual and would be sized using a flow-based numeric sizing criteria. Catch basin/inlet filter inserts (with absorbent booms added) are flow-based BMPs. Catch basin/inlet filter inserts reduce sediment, trash, debris, oil and grease from the flow and pesticides that attach to sediment. The catch basin/inlet filter inserts must be capable of treating the required treatment flow for the area of the project site draining to the catch basin or inlet. These BMPs would-be incorporated to meet the requirements of the Storm Water Standards manual and would be sized using a flow-based numeric sizing criteria. The required treatment flow for in-line storm water treatment units andlor catch basinlit).let filter inserts is calculated using the flow-based numeric sizing criteria provided in Table 3 of the Storm Water Standards manual, Table 3 -Numeric Sizing Treatment Standards (Section III of Storm Water Standards). Appendix C provides calculations fo~ water quality treatment flow requirements for the project based on the following numeric sizing criteria: "the maxImum flow rate of runoff produced from a rainfall intensity of 0.2 inch of rainfall per hour for each hour of a storm event". For the purposes of this water quality technical report, Suntree Technologies filter inserts and KriStar-Enterprises, Inc. filter inserts (named FloGard+PLUS) have been sized according to Prepared By: Rick Engineering Company 8 August 29, 2003 ST:rh\R:\d..) 4437\Report\SWMP (001 )_doc r-----------------------------------------------------------------------~------~---- I I I I I I I I I I I.

The specific structural BMPs that have been selected for installation throughout the development area are listed in the tables provided in Appendices D and E ofthis report. Approximate costs for both manufacturers have been provided in Appendix G of this report. CDS Technologies in-line treatment units have been sized according to water quality treatment requirements for lot 21 and approximate costs have been provided. Additional approved manufacturers ofin-line treatment facilities exist and maybe substituted if the appropriate calculations are performed to size each facility according to its own unique water quality treatment capacities.

Manufacturers often offer servicing for their own facilities, however, maintenance services are also offered through a variety of other manufacturers and cleaners as well. Th~ frequency of maintenance required is site and drainage area specific. The units should be inspected periodically to assure its condition is adequate to handle anticipated runoff. Initially following the installation of new treatment BMPs, it is important to check that the unit is functioning properly and measure the amount of deposition occurring from specific storm events. At a minimum, inspections should be made on a monthly basis and after every storm event to check that the unit is functioning properly and whether the unit requit~s servicing at 'that time. Based on these inspections, it may be necessary to adjust the frequency of schedule<l in~pections and maintenance cleanings. It is important to note that for the purpose of this water quality technical report, anticipated maintenance costs and the frequency of servicing (as discussed below for "Anticipated Maintenance Cost of Post-Construction Structural BMPs") are approximated and do not reflect the periodic inspections that are necessary to determine the actual frequency that site specific units will require. Specific to the curb inlet filter inserts provided by KriStar Enterprises, mc., serv.ice procedures include the removal of the manhole cover, vacuuming the collected debris,. replacing the hydrocarbon pouches as necessary (sorbent material), inspecting for needed repairs andlor replacement ofthe filter medium, closing the manhole cover, properly disposing of the waste, and recording the maintenance service for future reference. Specific to the curb inlet filter inserts provided by Suntree Technologies, service procedures include the removal of the manhole cover, removing the curb inlet basket, properly disposing of Prepared By: Rick Engineering Company 10 August 29, 2003 ST:rti\R:\d _ i 4437\Report\SWMP (001 ).doc ··1 I I I I I I I I I I I I I I II I I I the waste, replacing the hydrocarbon absorption boom (sorbent material), returning the filter to its secure position and closing the manhole cover, and reporting on debris and condition of filters . for the maintenance service. Specific to the CDS Technologies units, "a unit can be cleaned using a vacuum truck or a small clamshell bucket, or a basket can be provided to fit a standard sump," as specified in the "CDS Technologies Storm Water Pollution Control Technical Manual," date:d July 2002. If a basket is desired, CDS Technologies should be advised so that the material and installation costs can be adjusted accordingly. Anticipated Maintenance Cost of Post-Construction Structural BMPs Please refer to Appendix G of this water quality technical report for a summary of the . approximate maintenance costs associated with the proposed post-construetion BMPs. ~he annual maintenance cost; provided within Appendix G assume that the catch basin inlet filters will be serviced four times a year, and the CDS units twice a year. However, periodic inspections should be made to ensure the unit is functioning properly and that the frequency of maintenance does not need to be increased (as described above in· "Typical Maintenance Procedures for Treatment Control BMPs"). It is important to realize the annual maintenance costs provided within this report are preliminary and are approximations, which do notteflect the actual frequency that installed units may require servicing. Pursuant to information provided to Rick Engineering Company on May 20, 2002 from Bio Clean En~ironmental Services (a provider/vendor of Suntree Technologies Curb Inlet Baskets), maintenance costs for filter inserts are $316.00 per inlet per year, which assumes four $79.00 cleanings per year per inlet. It is recommended that maintenance requirements are monitored for any necessary increase in frequency. Pursuant to a phone conversation made on April 23, 2003 with Bob Griese of Downstream Services (a local distributor of KriStar Enterprises' FloGard+PLUS units), maintenance costs associated with the filter inserts range from approximately $150.00 to $450.00 per inlet per year .

It is recommended that maintenance requirements be monitored for any necessary increase in frequency. Pursuant to a phone conversation with Gordon Wilson of CDS Technologies, mc. on June 3, 2003, maintenance costs associated with the PMSU20 _15_ 4 treatment unit proposed for this project is approximately $1,470 per unit per year, based on two cleanings a year. The number of cleanings a year is based on soil and site conditions and may range from one to four cleanings a year. It is important to note that a variety of vendors distribute, install, and maintain these types of treatment facilities:and may offer significantly different costs associated with each unit than those provided within this technical report.

Systems SCOPE: Federal, State an~ Local Clean Water Act regulations and those of insurance carriers require that stonnwater filtration systems be maintained and serviced on a recurring basis. The intent of the regulations is to ensure't4at the systems efficiently r~move petroleum hydrocarbons, chemicals, sedinient and other harmful pollutants from stoi-mwa~er runoff. . RECOI\1l\1END.ED FREQUENCY OF SERVICE: Drainage Protection Systems (DPS) re90mmends that catch basin filtration systems be serviced on a recurring basis. The ,frequency depends on the amount of runoff, 'pollutant loading and interference from debris (Ieaves~ vegetation, cans, paper, etc.). As ~ minimum., it is. tecon:uTI.ende~ that each installation be serviced' a minimum of three times per y~ar, wj~h a change of filter . nie~ium once per year. SERVICE PROCEDURES 1. The catch basin shall be visuaily inspected f~r defects and. possible illegal dumping. if defects that affect the efficiency of the catch basin are found, the 9ustomer repreSentative will.be SO notified and a note made on the catch basin. service log; If illegal dumping has occurred, the proper authorities and prop~rty owner repr~sentatiye should be notified as . soon as possible. Debris around the. catch basin shall be collected and placed in a DOT approved container for later di~pos~1. . . 2. Depending on the type of system, the catch basin grate or manhole cover will be removed ··and the cond,ition of the 'filter and filte~ me4ium visually inspected. Serviceability' of the gaskets, silicone sealant and stainleSs steel concrete anchors should be determined a~d a check made to insure proper P9sitioning of the filter within t~e·catch basin. Problems found with the filter will be corrected and noted on t~e catch pasin service log. The filter medium pouches will be inspected for remaining useful life and rep~aced as ne~ed. 3. The collected debris will be vacu:umed'from tfie filter and placed in. a DOT approved storage tank .. Materials in the filter that are questionable in tetms of polhltloq po~ential will be placed: in a separate DOT approved con~ainer. Once th~ debris has b.ren removed, the filter liner and liner connections will be inspected fot damage. Damage to the liner or liner connections .will be corrected ~nd an appropriate notation made on the catch basin. s,ervice' log. . . 4. After the filter is cleaned, and :necess~ry repairs or adjustments made, the grate or . manhole cover will be replaced. The amount and typ.e of debris removed from the filter will be'fecord~' on the catch basin.service log. Recommendations' orpotentlill problem.s will also be noted on the catch basin serv.ice log. . :-d l-r ... ·····,. '. .' l.r I~ I' I' ,1, I I l.. ~~ I ~ I 1 I. ; .. I j I .1. I J I j " . EXCHANGE AND DISPOSAL OF EXPOSED FILTER :MEDTIJM The. frequency of filter medium pouch exchange will be in accordance with the maintenance agreement. DPS recommends that the medium be changed at least once per year. During the appropriate service call, or if so determined by the service techniCian, the'filter'medium pouches will be replaced. with new pouches and the exposed pouches placed in Ii. separa~-e DOT approved container. Once the filter !1ledium is removed, DPS takes possession of the waste and becomes responsible ror proper handling and disposal. The exposed mediufil and the debris removed from .. the filter and catch basin will be kept in separate DOT approved coritainers. Because the task-of the filter medium is to remove petrole~m'hydrocarbons, some heavy met'als and other harmful pollutants from stormwater runoff, the pouches must be treated. as' an EPA Class 2 Hazardous Waste and disposed of in accordance with local, state and federal agency-regulations .. DISPOSAL OF REMOVED DEBRIS Debris removed from the catch basin will be placed in a DOT approved container. Once'~he , " debris is removed from the catch basin" DPS takes possession and becomes responsible for proper disposal. The debris removed from the catch basins will be transported off site, tested arid profiled to'determine the proper method of disposaL After the debris is profiled, it will be .- mani(ested and transported to an appropriate waste facility. All manifests and. test results will be retained by DPS. Copies of the manifests and test results. can be supp1i~ upon request of the customer. . CATCH BASIN SERVICE LOGS , . Every catch basil? that contains a filter will be assigned an identifying tracking number. A catch basin',ser.:vice log folder will be assembled for-each specific site. The catch basin se,rvice log will be used to track the' debris removed and any potential problems for each individual catch basin for each service call. After each service call, copies of the catch basin service log will be forwarded to the customer and these should be placed in the/older:·provided to the customer by .DPS. DPS . will send copies ofthe service logs to the appropr~ate government agency upon requ~s~ of the customer. . . . ADDITIONAL SERVICES, IF REQUIRED Services not mcIuded'in the foregoing service agreement, but may be necessary, are removal and disposal of debris, sediment,. etc. at the bottom of the catch basins or more frequent .filter services. DPS also has the capability of servic~g catch basins without filters, underground oil/water . separators, stormwater iriterceptors, and other devices.

Under 'sueh eonditions 'it may be ad-visable to use a weir with a thleker crest. It is often con- venient to use an' existi)"lg weir or overflow dam' for mep.suring discharges. Weirs of various dlmensions and sha.pes are used in hydraulic structures. When designing 'such'struetures it is important to be able to estimate approximately the dis~h;rges OV& these w~irs (p. 2-15). The amount of water which will pass over a weir, not sharp- crested., depends tq a large extent upon. its' sectional form and the shape ·of its crest, and it is necessary to resort to experiment . to determine the discharge over any particular shape. Inas- 'much as the number cif shapes of weirs is uiilimited, it is not to be expected that experimental data are or ever will be available fo; them all. There are available, however, the results of several series of experiments on :weirs of different crosS sections which furnish much. valuable information for detei:m.ini:ng discharges over weirs of the same or similar shapes. The available experiments are not extensive enough for a comprehensive study of the effect of velocity of Ilopproach on weirl3 not sharP-crested. The coefficients given in this chapter probably apply more accurately where the velocity of approach . is not .high. From a consideration of s.harp-crested weirs ~t . appears that· discharges, . for high. yelociti~s. of app!.~fl:c1i" will be somewhat greater tl;tan is given by formula (5-10). Since exp~llnental conditions will'seldom be duplicated in practice, it is probable th!J-t errors inay resUlt from th~ general use of the coefficients' given in this chapter. Extreme accuracy, however, is not always necessary in design, where uncertain~r as to the exact quantity of water to be provided for may exist. The problem of establi~hing a fixed relation qetween head and dischargel for weirs not sharp-crested, is complic\Lted Py' the ..fact that the nappe may assume a variety. of forms in passing over. the weir. For each modification of nappe form, . there is a, corresponding change m the relation between head and Qjscharge. The effect of this co~dition ~ more nof.iceable /..-... for low heads. The nappe mll-Y undergo.~Beveral of these mddifications in succession as the head is varied.. T~e I succe~sive forms that appear ,with an increasing stage may differ from those p'er-., taining to similar stages v6th a decreasing head. . The head at . which the changes of nippe.form·occur'·varies with the rate of, . WEIRS 5-23 change of head, whether increasing or decre!lsing, and with other' conditions. Among weirs of irregular section there is a. large cla:ss for which, from· the nature of their section, the napp~ can assume only one form unless drowned. Such weirs, it is suggested, may, if properly calibrated, equal or exceed the usefuJ.D.ess of the thin-edged weir for purposes of stream gaging, b~cause of their stability of section and because the thin-edged weir is, not free from modifi.ca~ion of nappe form for low heads. 'Broad-crested Weirs. A weir approximately rectangular in cross section is. termed a broad-crested weir. Unless otherwise noted, it will be assumed to have vertical fac'es, a pJane level b FIG. 5-6. Broad-crested' weir. crest, and sharp right-angled corners. Figure 5-6'represents a: broad-crest'ed weir of breadth b. The h~ad H should be measured at least 2.SH upstream from the weir. ~ecause of the sharp upstream ed~e, contraction of the nappe occurs. Surface contraetion begins at. a point slightly upstream from .the weir. . The disc4arge over broad-crested weirs is usually expressed l.:!y the equation Q = 'CLHH. '. (5,..10) Experiments on broad-crested weirs have been performed by Blackwell:, Bazin, Woodburn, the U.S. Deep Waterways Board, ll.nd, th~ "0:9" Geo.logical Survey. These exper:iments cover' a wide range of conditions as to head, breadth, and height pf weir. Considerable discrepancy e~ists Pl ~he results ot" the different experimenters, especialJy for ~ads below 0.5 ft. For heads from 0.5 tq about 1.5 it the coefficient becomes more uniform, ~nd for' heads from i.5 ft to tb,at at whi.ch,the nappe becomes detached from the crest, the coeffici~nt as given by·the .different experiments is nearly constant and equals approximately 2.63.
