When combined with a minimum lot size of o 5 acres per dwelling unit for a septic system, this area is severely restricted for future development In addition, a substantial portion of the remaining land area is designated as Resource Preservation These two factors will limit development and the future number of septic systems allowed in the San Timoteo Canyon area. Figure 1 3 shows the permitted septic systems They account for only 14 4% of the City's area or about 3,354 acres Restricted Areas for Onsite Wastewater Treatment System Preserves and Parks As mentioned prior, a combination of the General Plan Requirements and terrain restricts development within San Timoteo Canyon Hillsides often exceed 30% of slope Very little level ground is found within the canyon Numerous minor canyons provide tittle relief to this condition and act as funnels, collecting runoff from the hillsides and creating local flooding Soils within the area have proven to be highly erosive The cost of developing in this area is discouraging and has been mostly single-family homes on single lots North of San Timoteo Canyon Road between Alessandro Road and Nevada Street, the westerly City Limit in this area, 200 acres has been dedicated to The San Timoteo Nature Sanctuary This would preclude any further development in this area In addition and to a lesser extent, portions near to San Timoteo Creek have also been dedicated to The San Timoteo Nature Preserve Combined, these two areas severely limit the available area for development in the canyon South of the intersection of Creekside Drive and Horse Trail Dnve, a City owned 40 -acre park has been constructed This park, called Sunset Hills Park, has been left in a natural state, with some hiking or horseback riding trails No sewer service is available and as of this date, no septic system is planned for the park City of Redlands — Local Agency Management Program Page 5 • • 1 • ',es. : • e • ? ! se ■ • as ■ • ■ , ~•. • .• + ■ • cts If a • • 1 • ■ ■ • a ■ a•? • 1 rh 4. • leg • s ;� •■•. • • • • •■•'•■ r • • i • g •• •• • ••! t • _■ • M ■• ■ ■ • •� • M • • • 1. • • •:,• •• • ! •a•a tsi • r��•+ • • r •a • Y bf4*4•4•30:. ell.lilligr • r kp o • : .4)4 PI• :`• .• • w • • •• ■ . oijii — . ■ M • a • 1 • • •...• • ▪ • . •• • esi• * • • /lira ■ • + a ! • • Permitted Septic Systems Parcels with Septic Tank Redlands Redlands Sphere of Influence Figure 1.3 cum Qr CITY THAT WORKS" At the intersection of Sutherlands Drive and South Lane, a 14 5 -acre park owned by the City has been established Named Oakmont Park, this park, like Sunset Hills Park has been left in a natural state, with some hiking or horseback nding trails No sewer service is available and as of this date, no septic system is planned for the park Next to Oakmont Park and extending to the east City limit is the Herngt `Aki' Preserve More than 340 acres have been set aside for permanent conservation No sewer services have been provided Immediately south of the Herngt `Aki' Preserve and Live Oak Canyon Road is the Gateway Ranch, a 14 -acre site now being established as a regional hub for hikers, cyclists, equestnans, naturalists, ecologists, botanists, and birders for the inland area This was an existing functioning ranch and had a previously approved septic system Under the terms of development for this site, no further homes or dwelling may be constructed Finally, San Timoteo Creek has been designated as an impaired waterbody, which further restricts the use of OWTS in the canyon Sections 7 and 8 discuss the impacts of this designation and development is restricted in this area Figure 1 4 shows the areas in San Timoteo Canyon where development is restricted, due to topography, parks, and agricultural preserves Public Water Wells A search of the City's Geographic Information Systems (GIS) revealed 114 known wells within the City limits Redlands was once the center of the largest navel orange producing region in the world and the number of wells needed for irrigating citrus is not surprising Even though citrus farming has been in decline with subdivisions replacing orange groves, approximately 2,500 acres of citrus still remain in production Many of the wells that no longer irrigate orange groves are used for non -potable irrigation of landscaping The City of Redlands owns 15 domestic wells that pump directly into the water system or into reservoirs The City also receives water from two wells that are owned by the South Mountain Water Company All of these wells are adequately separated from sewerage facilities Waterbodies Redlands is located between the Santa Ana River to the north and south of San Timoteo Creek and Yucaipa Creek San Timoteo Creek was added to the 2014 and 2016 Integrated Report (303(d)) List, indicating a TMDL (Total Maximum Daily Load) will be required The remaining waterbodies, including any of the minor ones within City jurisdiction are un -impaired The Zana Channel runs more or less through the middle of Redlands and it is un -impaired Figure 1 5 shows the waterbodies in Redlands City of Redlands — Local Agency Management Program Page 7 1 i›,_ 1 1 Sewer Not Available Due to Topography • Sewer Not Available Due To Topography Redlands Redlands Sphere of Influence Figure 1 4 w N Scale E 0 0.5 Miles Sant na Ri Iver =alb.

CITY THAT WORKS" Percolation Testing The City requires percolation testing, and accompanying reports, to be prepared by a Qualified Professional For soil to be considered uniform, test results must fall within 25% of the mean percolation rate If not uniform, the most conservative test result will be used Determining the number of percolation tests required will be based on soil conditions and project type All percolation testing will be conducted per the procedures outlined in Appendix A of this LAMP, unless another method is approved in wnting by Building and Safety prior to any actual tests being performed Percolation testing x Is used to ensure the dispersal field is located in an area where no conditions exist, which could Adversely affect the performance of the system, or Result in groundwater contamination x Is used to determine the necessary area needed to treat, and maintain underground sewage properly x Must be in the general area of the disposal system, both primary and expansion, if the proposed area is known Seepage Pits The use of seepage pits, as a dispersal field, will only be allowed in instances where leach lines are not feasible, and minimum separation requirements to groundwater are met The City requires a 10- foot minimum separation from the bottom of the seepage pit to groundwater When the pit percolation is less than 10 minutes per inch (MPI), the following must occur x The separation to groundwater must be at least 40 feet from the bottom of the seepage pit, or x A sieve analysis of the soil, for a thickness of 10 feet below the bottom of the seepage pit, must contain at least 15% fines passing the #200 United States standard sieve Evaluation Methods Site evaluations contain site specific information, which includes a review of the physical features of the site Exploratory borings or trenches are the main evaluation methods to determine if there is adequate separation from the bottom of the dispersal system to the groundwater To determine the highest level of groundwater within the dispersal field, data from permitted wells, local water purveyors, and the United States Geological Survey (USGS) are used in addition to exploratory borings or trenches This section details the evaluation methods, as well as the information that will be reported City of Redlands — Local Agency Management Program Page 18 Parcel Features

preliminary exemption approval by the Santa Ana Regional Water Quality Control Board may be requested from the customer Additional information may be requested by the City of Redlands or the Santa Ana Regional Water Quality Control Board for review of the exemption request Special Considerations The majority of the City of Redlands is in a nver plain, where geologic conditions have a less significant impact on OWTS The hilly areas throughout the City, however, have significantly more geological factors that must be addressed prior to installing an OWTS This section City of Redlands — Local Agency Management Program Page 44 "CITYTsaiWo" discusses the various geological factors within the City that will be given special consideration when reviewing requests for OWTS installation Geological Factors The performance of OWTS is affected greatly by the geology of the land in which it is located Geological factors which must be accounted for prior to installing an OWTS include x Soil characteristics, x Slope stability, x Topography, x Landforms, and x Presence and movement of subsurface water Groundwater Conditions The City reties on local aquifers for both public and private water supplies Site evaluation includes identifying and documenting any signs of groundwater The documentation and soil permeability identified by a percolation test provides the basis for selecting OWTS design and separation distance of the dispersal system This documentation is obtained to minimize contamination of the groundwater in the local aquifers The identification and location of nearest supply wells and current groundwater quality should be included in any proposal when information is available Designated Maintenance Areas are Tier 3 Areas of Special Concern There are areas within the City that have a high density of OWTS Due to the unique topographical and hydrogeological conditions in these areas, additional monitoring and maintenance is required Domestic Well Usage Numerous domestic wells are located the City of Redlands Domestic wells are often used in conjunction with OWTS In an effort to ensure the protection of new and existing wells from the effects of OWTS, the following requirements exist x Minimum horizontal setback distances between OWTS and any well x Well water testing for all newly constructed wells x Allowing supplemental treatment as an option for OWTS in areas where there are potential impacts to groundwater due to - High domestic well usage, and/or - Existence of other limiting factors (i e , shallow groundwater or fast percolation rates) - Small lot size or high density City of Redlands - Local Agency Management Program Page 45 atmQr CITY THAT WORKS" Prohibited Discharge Conditions for Septic Tank Systems In an effort to ensure the proper functioning of septic tank systems, as well as prevent adverse effects to the environment, the following discharges are prohibited for septic tank systems x Surface water, ram, and/or other clear water x Toxic or hazardous chemicals to a domestic system x Water softener and iron filter discharge to a sewage disposal system or on the ground surface, unless specifically approved by Santa Ana Regional Water Quality Control Board Water softener and iron filter discharge must be disposed of at an approved disposal site Note Commercial developments will have individual monitoring ports for each unit connected to a confluent sewage disposal system if there is a single owner of the development Multi -owner units (condominium type) will have a separate system for each unit Surface Water Quality Protection Setback requirements are the pnmary source of protection for surface water These setbacks act as a buffer zone between the potential contaminants of the OWTS and the water body The requirements listed in the LAMP are consistent with the Basin Plan for the Santa Ana Regional Water Quality Control Board, as well as meeting or exceeding requirements outlined in the California Plumbing Code This section describes the requirements for surface water quality protection Watersheds Watersheds are reservoirs which serve as a source of drinking water supply for several downstream communities, and therefore require special protections These areas are outlined in the Basin Plan for the Santa Ana Regional Water Quality Control Board Increased setback standards are required for any OWTS proposal within 2,500 feet of surface water intake for public water supplies Impaired Water Bodies San Timoteo Creek within the City is listed as impaired, pursuant to the Clean Water Act Section 303(d) Any OWTS installed within 600 feet of the impaired water bodies contained in the 303(d) list is subject to the Advanced Protection Management Program (APMP) Refer to Section 8 for more information regarding impaired water bodies and the APMP Should any water body within the City become 303(d) designated at a future date, these standards will apply to it also Special Circumstances In the hillside portion of the City, there are multiple known OWTS installed prior to this LAMP When these systems are replaced or modified, they will be required to meet the current standards City of Redlands — Local Agency Management Program Page 46 eau Qr "A CITY THAT WO " The following factors will also be given special consideration and will be reviewed on a case- by - case basis x Density x Parcel size x Potential cumulative OWTS impact issues Note To provide greater flexibility to City residents, alternative systems may be approved on a case-by-case basis with revised standards for setback requirements See section 8 for details on alternate systems Tier 4 Classified OWTS As noted in the OWTS Policy section, Tier 4 is a temporary classification for all systems that have been found to be failing, and/or in need of repair OWTS which are included in Tier 4 must continue to meet applicable requirements of the LAMP, pending completion of corrective action This section provides detailed information regarding OWTS, which are classified as requiring corrective action Tier 4 Replacement Replacement of the OWTS where public sewer is available is prohibited The public sewer may be considered not available when such public sewer is located more than 200 feet from any property line This provision does not apply to replacement OWTS where the connection fees and construction cost are greater than twice the total cost of the replacement OWTS and the City determines that the discharge from the OWTS will not affect groundwater or surface water to a degree that makes it unfit for drinking or other uses OWTS Requiring Corrective Action OWTS have the primary purpose of protecting public health When systems are no longer meeting this purpose, they are deemed to be failing and require corrective action When this occurs, systems must be replaced, repaired, or modified to return to proper functioning and comply with Tier 2 or Tier 3 classifications as appropriate Failing OWTS include any OWTS that has x A Dispersal system failure which is no longer percolating wastewater adequately, causing — Pooling effluent, — Wastewater discharge to the surface,

minimum required management program for all Onsite Wastewater Treatment Systems (OWTS) located near a water body that has been fisted as impaired due to nitrogen or pathogen indicators, pursuant to the Clean Water Act, Section 303(d) City of Redlands is authonzed to implement APMPs in conjunction with an approved Local Agency Management Program (LAMP), or when there is no approved LAMP, APMPs can be approved under Tier 1 guidelines The City of Redlands will collaborate with the Regional Water Boards by sharing any information pertaining to the impairment, provide advice on potential remedies, and regulate OWTS to the extent that the City's authority allows for the improvement of the impairment Per the State Water Resources Control Board's OWTS Policy, OWTS which are located near impaired water bodies may be addressed by a Total Maximum Daily Load (TMDL) and its implementation program, or special provisions contained in a LAMP Total Maximum Daily Load Section 303(d) of the Clean Water act requires each State to establish a TMDL for each impaired water body to address the pollutant(s) causing the impairment In California, TMDLs are City of Redlands - Local Agency Management Program Page 54 cum Qr "A CITY THAT WORKS" generally adopted as Basin Plan amendments and contain implementation plans detailing how water quality standards will be attained This section provides information regarding the TMDL requirements for impaired water bodies located within the City of Redlands Total Maximum Daily Load Calculation According to the United States Environmental Protection Agency (EPA) website, a TMDL calculates the maximum amount of a pollutant allowed to enter a water body so the water body will meet, and continue to meet, water quality standards for that particular pollutant The TMDL calculation includes both anthropogenic and natural background sources of pollutants, which includes allocations to x Point sources [Wasteload Allocation (WA)], and x Nonpoint sources [Load Allocation (LA)] TMDLs must also include a margin of safety (MOS) to account for the uncertainty in predicting how well pollutant reduction will result in meeting water quality standards, and account for seasonal variations The TMDL calculation is TMDL = Sum of WA (point sources) + Sum of LA (nonpoint sources & background) + MOS Geographic Area for Advanced Protection Management Program Where there is an approved TMDL, the geographic area for each water body's APMP is defined by the applicable TMDL When there is not an approved TMDL which defines the geographic area, it will be 600 lmear feet (in the horizontal map direction) of a water body listed on the 303(d) list, where the edge of the water body is the x Natural or levied bank for creeks and rivers x High water mark for lakes and reservoirs x High tide line for tidally influenced water bodies, as appropnate There may be OWTS located near impaired water bodies that would not be included in the

OWTS with adequate infiltration surface area based on an expected percolation rate and the rate of loading, and to provide for a system intended to allow for a long-term expectation of satisfactory performance Percolation testing is required for all new OWTS All percolation testing for dispersal systems except vertical seepage pits in the City of Redlands shall be conducted using the following procedures The test shall be performed by or under the direct supervision of a California registered professional engineer, or geologist Any deviation shall be authorized only after receiving written approval by the City of Redlands Building and Safety Department Note Grading or clearing of brush for the purposes of completing a percolation test will require approval from Engineering and requires the implementation of wind and storm water erosion BMPs Test Holes Number of Test Holes 1 A minimum of four test holes are required when percolation rates are less than 60 minutes per inch (mpi) 2 A minimum of six test holes is required when the average percolation rate is more than 60 mpi 3 Additional test holes may be necessary on a site-specific basis for reasons that include, but are not limited to the following x Unacceptable or failed tests x Areas of the disposal field require exclusion x Test holes were not located in the area of the disposal field Depth of Testing 1 Test holes shall be representative of the dispersal system installation depth 2 Conditions which may require testing deeper than leach line depth x Shallow consolidated rock or impervious soil layers x Slope

12-14 inches in depth shall be excavated into the bottom of the trench Preparation of Test Holes 1 The sides and bottom of the holes shall be scarified to remove the areas that became smeared by the auger or other tool used to develop the hole 2 All loose material should be removed from the hole Soil Classification 1 All test holes and deep borings shall have soil types described according to the American Society for Testing and Matenals (ASTM) Soil Classification System (Unified) 2 All borings are to be reported, including any, which encountered groundwater or refusal 3 Comments about consolidation and friable characteristics shall be included in the report Presoaking the Test Holes Procedure 1 Carefully fill the test hole with 12-14 inches of clear water 2 Maintain 12-14 inches of clear water for a minimum of four (4) hours After four hours, allow the water column to drop overnight (Testing must be done the next day, but not less than 15 hours or more than 30 hours after the initial four-hour presoak) 3 Overnight Option If clay soils are present, it is recommended to maintain the 12-14 inch water overnight A siphon can be used to maintain the supply at a constant level 4 In highly permeable sandy soils with no clay and/or silt, the presoak procedure may not be possible If, after filling the hole twice with 12-14 inches of clear water, the water seeps completely away

Saturation and Swelling 1 The test hole must be saturated prior to testing The time required for this can vary greatly 2 Swelling is caused by the intrusion of water into soil particles that expand as they become wet This is typically a long process and most likely to occur in clay soils Use of Inserts 1 If sidewalls are not stable or sloughing results in changing depth, the test hole may be abandoned or retested after means are taken to shore up the sides The holes shall be re -cleaned prior to resuming the test 2 Options for shonng or maintaining test hole stability x Hardware cloth (1/8 inch grid) x Perforated pipe or containers x Gravel pack NOTE A correction factor is necessary if a gravel pack is used Show all calculations on the test report Determination of Percolation Rates Dependmg on the soil type and permeability, and the results of the presoak, variations in the procedures used for determining percolation rates will occur Testing shall proceed based on the conditions outlined in the following examples Example 1 — Water remains overnight in the test hole following the four-hour presoak (Unless an overnight siphon is used ) Example 2 — Soil with a fast percolation rate is encountered where two columns of 12-14 inches of water percolates in less than 30 minutes for each column during the presoak Example 3 — No water remains in the test hole after the four-hour presoak Example 1 Procedure 1 Adjust depth of water to 6 inches in the hole 2 Take two (2) readings at thirty (30) minute intervals and report percolation rate as the slower of the two readings NOTE When a minimum amount of water remains due to a damaged hole or silting, the hole may be cleaned out and tested under Example 3, starting with the presoak Example 2 Procedure 1 Begin test the next day, but not less than 15 hours or more than 30 hours after presoak 2 Fill the hole twice with 12-14 orches of water Observe to see if each column of water seeps away in less than 30 minutes If so, proceed with the percolation test If not, go to Example 3 City of Redlands — Local Agency Management Program Page 85 cum Qr CnTYTiATWORKsn 3 Refill hole to 6 inches above the bottom 4 Measure from a fixed reference point at ten (10) minute intervals over a period of one (1) hour Measure to the nearest 1/16th inch Add water at each 10 -minute time interval 5 Continue 10 minute readings as long as necessary to obtain a "stabilized" rate with the last 2 rate readings not varying more than 1/16th inch or for a duration of four (4) hours The last water level drop will be considered in the percolation rate Example 3 Procedure 1 Begin test the next day, but not less than 15 hours or more than 30 hours after presoak 2 Clean out the silt and mud and add 2 inches of 3/8 inch pea gravel 3 Adjust water depth to 6 inch above the pea gravel buffer and measure from a fixed reference point at 30 -minute intervals Measure to the nearest 1/16th inch NOTE It is not necessary to record data points for the first hour as this is an adjustment penod and a reestablishment of a wetted boundary 4 Refill the hole as necessary between readings to maintain a 6 -inch column of water over the pea gravel If a fall of 1 inch or less is recorded, the test can continue without refilling until the next 30 -minute reading interval 5 Continue recording readings at 30 -minute intervals for a minimum of four (4) hours 6 The last water level drop is used to calculate the percolation rate Calculations and Measurements Calculation Example The percolation rate is reported in minutes per inch For example, a 30 -minute time interval with a 3/4 inch fall would be as follows 30 minutes — 3/4 inch = 40 minutes per inch (mix) Measurement Principles 1 The time interval for readings are to reflect the actual times and are to be maintained as near as possible to the intervals outlined for the test (10 or 30 minutes) 2 Measurements to the nearest 1/16th inch should be adjusted to the slowest rate, e g , a reading observed between 3/8 inch and 5/16 inch (80 mpi and 96 mpi) would be reported as 96 mpi Measurements, Special Considerations 1 Measurement from a fixed reference point shall be from a platform that is stable and represents the center of the test hole City of Redlands — Local Agency Management Program Page 86 "A CITY THAT WO " 2 Accurate measurement is vital and in cases of
